INTRODUCTION
In England and Wales, where under the CPR, the Court orders one party (the paying party) to pay the (non-fixed) costs of the other party (the receiving party), the Court can assess those costs[1]:
(a) summarily (immediately, or at a later date); or
(b) by ordering that they be the subject of a detailed assessment.
(unless any rule, practice direction or other enactment provides otherwise; see r.44.6 and Practice Direction 47, paragraph 8[2]).
Where they are ordered to be assessed, the default is for the costs to be the subject of a detailed assessment, unless the Court orders otherwise[3].
Where the Court orders that those costs be the subject of a detailed assessment, the receiving party will have an incentive to commence those detail assessment proceedings quickly, in order to get a figure for what costs the paying party must pay the receiving party, and hopefully, swift payment thereafter. While a payment on account of costs order under r.44.2(8)[4] will go some way to dampen this incentive, there will still be the incentive there. There can be however a myrad of reasons why a receiving party might delay/dither, and not start detail assessment proceedings quickly.
In the first instance, the CPR does specify deadlines for commencing detail assessment proceedings. Which raises the question, what then happens if a CPR specified deadline is missed?[5] What are the consequences for the receiving party and paying party, respectively? what options does the paying party have?
This article will consider this, in light of:
(1) CPR r.47.7 and r.47.8, contained in Chapter II, entitled 'Costs Payable by One Party to Another-Commencement of Detailed Assessment Proceedings', within CPR Part 44, entitled 'Procedure for detailed assessment of costs and default provisions';
(2) Parts of Practice Direction 47 ('PD47');

Two points:
(1) An important point made in Rattan (not an inter parties costs order case[7]) is that, in the situation under consideration:
(a) the Court has already awarded the receiving party with an order in the receiving party's favour; and so,
(b) 'The position was broadly comparable to the delayed enforcement of the judgment, rather than the delayed pursuit of a claim.' (Rattan, paragraph 65)
(2) detailed assessment proceedings are commenced, as set out in r.47.6(1)[8], by serving on the paying party:
(a) notice of commencement in the relevant practice form (form N252); together with,
(b) a copy (or copies) of the bill of costs, as required by PD47; and
(c) if required by PD47, a breakdown of the costs claimed for each phase of the proceedings (using Precedent Q)(unless the same information is fully provided in an electronic bill).
We turn to the CPR rules first[9].
CIVIL PROCEDURE RULES
CPR r.47.7
CPR r.47.7 is entitled 'Period for commencing detailed assessment proceedings' and reads:
'The following table shows the period for commencing detailed assessment proceedings.'
There is then a 2 (column) x 3 (row) table. Not all of it is relevant for present purposes[10]. The first column is entitled 'Source of right to detailed assessment' and, the relevant row is row 1, which states:
'Judgement, direction, order, award or other determination.'
The second column is entitled 'Time by which detailed assessment proceedings must be commenced' and for, row 1, it reads:
'3 months after the date of the judgment etc. Where detailed assessment is stayed pending an appeal, 3 months after the date of the order lifting the stay'
Accordingly, where a Court has ordered a detailed assessment of costs, r.47.7 requires that the detailed assessment of costs be commenced within 3 months (unless the order was stayed pending an appeal[11]).
PD47, paragraph 6 supplements the CPR rules. PD47, paragraph 6 is entitled 'Period for commencing detailed assessment proceedings: rule 47.7' and reads:
'6.1 The time for commencing the detailed assessment proceedings may be extended or shortened either by agreement (rule 2.11) or by the court (rule 3.1(2)(a)). Any application is to the appropriate office.
6.2 The detailed assessment proceedings are commenced by service of the documents referred to. Permission to commence assessment proceedings out of time is not required.'
Accordingly,
(1) in light of the wording to:
(a) CPR r.2.11[12];
(b) CPR r.3.1(2)(a))[13];
(c) CPR r.47.8(1)(b),
it is clear that the deadline for commencing detailed assessment proceedings, can be changed by: (a) Court order/direction; or (b) agreement between the parties.
(2) the commencement itself, of detailed assessment proceedings, outside of time, does not require Court permission[14].
CPR r.47.8
CPR r.47.8 is entitled 'Sanction for delay in commencing detailed assessment proceedings' and reads:
'(1) Where the receiving party fails to commence detailed assessment proceedings within the period specified-
(a) in rule 47.7; or
(b) by any direction of the court,
the paying party may apply for an order requiring the receiving party to commence detailed assessment proceedings within such time as the court may specify.
(2) On an application under paragraph (1), the court may direct that, unless the receiving party commences detailed assessment proceedings within the time specified by the court, all or part of the costs to which the receiving party would otherwise be entitled will be disallowed.
(3) If-
(a) the paying party has not made an application in accordance with paragraph (1); and
(b) the receiving party commences the proceedings later than the period specified in rule 47.7,
the court may disallow all or part of the interest otherwise payable to the receiving party under-
(i) section 17 of the Judgments Act 1838; or
(ii) section 74 of the County Courts Act 1984,
but will not impose any other sanction except in accordance with rule 44.11 (powers in relation to misconduct).
(4) Where the costs to be assessed in a detailed assessment are payable out of the Community Legal Service Fund, this rule applies as if the receiving party were the solicitor to whom the costs are payable and the paying party were the Legal Services Commission.
(5) Where the costs to be assessed in a detailed assessment are payable by the Lord Chancellor under Part 1 of the Legal Aid, Sentencing and Punishment of Offenders Act 2012, this rule applies as if the receiving party were the solicitor to whom the costs are payable and the paying party were the Lord Chancellor.'
As will be apparent, the sanction for delaying the commencement detailed assessment proceedings, beyond the 3 months stipulated, is that:
(1) the paying party (who may be, in the circumstances specified in r.47.7(4) or (5), be the Legal Services Commission or Lord Chancellor, respectively) may apply for an order requiring the receiving party to commence detailed assessment proceedings within such time as the court may specify ('Application for court imposed detailed assessment commencement deadline' or 'r.47.8(1)-(2) Application'). On such an application, the Court may direct that, unless the receiving party commences detailed assessment proceedings within the time specified by the court, all or part of the costs to which the receiving party would otherwise be entitled will be disallowed.
As stated by Master Brown in Awan, 'Applications such as this are reasonably common and often agreed or take little time to determine...' (paragraph 4). Typically a 30 minute listing might be given.
(2) where:
(a) the receiving party commences the proceedings later than the period specified in rule 47.7; and there was,
(b) no Application for court imposed detailed assessment commencement deadline, made by the paying party,
the Court may still impose 2 sanctions:
(1) one of disallowing interest, otherwise payable to the receiving party, whether in whole or in part, under either of 2 statutes (as applicable);
(2) one of imposing a r.44.11 sanction (a misconduct sanction)
PD47, paragraph 7 supplements the CPR rules. PD47, paragraph 7 is entitled 'Sanction for delay in commencing detailed assessment proceedings: rule 47.8' and reads:
'An application for an order under rule 47.8 must be made in writing and be issued in the appropriate office. The application notice must be served at least 7 days before the hearing.'
TYPES OF IMPOSABLE SANCTIONS
Before considering r.47.8(1)-(2) Application (i.e. an application for court imposed detailed assessment commencement deadline) in detail, it is convenient to consider the 3 'types' of sanction which may be imposed in this area of law. Which can be imposed, will depend on the circumstances before the Court:
(1) 2 are 'disallowances' - these are imposable only on the receiving party; and the other is,
(2) a r.47.11 misconduct sanction - these may be imposed on either party.
Looking at the 2 'disallowances', these are:
(1) disallowance of costs - available only as a sanction for non-compliance with a Court imposed deadline for detailed assessment proceedings commencement;
(2) disallowance of interest - available only as a sanction where no r.47.8(1)-(2) Application is made, and the receiving party commences the proceedings outside the 3 months permitted.
The sanction imposable under r.44.11 is this disallowance of costs (r.44.11(2)).
ISSUED R.47.8(1)-(2) APPLICATION - APPLICATION FOR COURT IMPOSED DETAILED ASSESSMENT COMMENCEMENT DEADLINE
Where the CPR prescribed detailed assessment commencement deadline is missed by the receiving party, the paying party can apply under r.47.8(1)-(2) for a Court imposed detailed assessment commencement deadline. The purpose of giving the paying party this option/provision, is in order to enable the paying party to be able to obtain an order (an unless order) from the Court, requirng the receiving party to serve a notice of commencement by a certain, Court imposed, date, on pain of a sanction (disallowance, under r.47.8(2), of costs) for non-compliance. This gives, in the paying party's hand, a way to prevent (or at least, disincentivise) further delay/'drift', in getting to a final determination on the quantum of costs, under the costs order, the paying party has to pay the receiving party. As to this, Lindsay J in Haji-Ioannou 279 made 2 observations:
(1) '...if the receiving party does dally then the paying party has a remedy in its own hands, one that, by way of an “Unless” Order, may carry with it a very powerful sanction.' (paragraph 9). Later, Lindsay J described this as '...a convenient and inexpensive mechanism (47.8(1)) by which to counter delay....'
(2) '...parties are, under CPR 1.3, required to help the court to further the overriding objective of, inter alia, ensuring that a case is dealt with expeditiously. A paying party who sits on his hands whilst the receiving party dallies is thus not himself wholly free of blame.' (Less, paragraph 9)
A third obversation can be added, from Warren J in Less:
(3) because a paying party can make a r.47.8(1)-(2) Application, delay by the receiving party, in commencing the detailed assessment proceedings, is not a violation of the paying party's art.6 rights;
Is commencing the detailed assessment proceedings, within the CPR prescribed 3 month window, optional?
In Awan, Master Brown addressed the question: 'whether under the provision CPR 47 there is in effect an optional scheme whereby parties may not commence detailed assessment if a costs order is made in conventional terms.' (paragraph 30.
As to this, Master Brown in Awan concluded that the obligation under 47.7, to serve a notice to commence a detailed assessment, within the CPR prescribed 3 months, was not optional; it was obligatory. He said, at paragraphs 31, 33 to 40:
'In my judgment, the rules are clear. A party in whose favour an order for costs is made - an order which provides for detailed assessment, must commence detailed assessment within three months. The word 'must', in the provisions of 47.7. is of importance and plainly, to my mind, is inconsistent with this step being optional.
...
Quite apart from the use of the word 'must' there are quite a number of other matters which support the conclusion that there is an obligation to commence detailed assessment and that is it not optional.
47.8 provides:
"where the receiving party fails to commence detailed assessment proceedings within the period specified in rule 47".
The word 'fails' connotes to my mind an obligation to commence. There must be an obligation to do so because it is only if there is obligation to do so could there be a 'failure'. At least that to my mind is the correct reading of the rules in the context of the other provisions.
Further, there are comments of Court of Appeal in [Haji-Ioannou 1663]. In that case a party failed to commence detailed assessment proceedings within the relevant period. The Court were principally concerned with the provisions of CPR 44.14, as they were, which set out powers in relation to misconduct in detailed assessment proceedings and whether there had been any misconduct. Longmore LJ said this at [9], dealing with delay:
"The judge then proceeded, rightly, to hold that there is no inconsistency between part 44.14 and 47.8. It may, however, be said that there is a certain tension between them. A failure to commence detailed assessment proceedings within the three months required by Part 47.7 may fairly be described as a failure to comply with a rule and, therefore, at least be included in the general term 'fails to comply with a rule' within the words in 44.14(1)(a). Yet it can scarcely be supposed that, when 47.8 provides the court 'must not impose any' sanction other than the disallowance of interest 'except in accordance with rule 44.14 (powers in relation to misconduct)', every failure to commence detailed assessment proceedings should be regarded as misconduct and permit the disallowance of costs as well as interest."
And then at [17]:
"Of course delay is to be deprecated but where the relevant rule not only gives to the party at the receiving end of the delay the option of preventing further delay by himself taking the initiative but also spells out the normal sanction for penalising such delay … it seems to me that the court should be hesitant to exercise further powers to impose further penalties by way of reducing otherwise allowable costs."
... it is clear from these passages that the court took CPR 47.7 to be a rule that imposes an obligation to serve detailed assessment proceedings within three months and that failure to comply with that rule is a breach of that rule. As Longmore LJ makes clear, not every time this happens will it amount to misconduct. But the absence of misconduct does not mean there has not been a failure to comply with a rule.
There may be indeed be good reasons why a party is unable to serve a bill within three months. It can be an unrealistic period of time to prepare a bill in the high value cases that we sometime deal with. In such cases the parties can agree extensions of time. It is perhaps surprising to me, and perhaps to others, how infrequently parties apply for an extension of time for service of bills. But parties do, sometimes I think, agree extensions of time. There is moreover no doubt, that the practice of parties is generally to agree that judgment rate interest does not run in a period of delay - as a reflection of a failure to commence within time. So, at least as I see it, the notion that the commencement is optional is not accordance with general practice and the way parties generally interpret the rules.
There are perhaps other things to be said about this but for all the reasons I have given in my view the obligation under 47.7 is not optional. It does not become optional there having been a failure to commence proceedings in the three months. The receiving party is still in breach after the three month period - as 7.8(2) might suggest. Accordingly, I reject the [r.47.8(1)-(2) Respondent's] case on this point. They should have served a Bill and Notice of Commencement within 3 months of the costs order an [SIC] are in breach of the rules.
That takes me to the second point of construction which arises on this application.' [words underlined are in italics in original; bold added]
Does 47.8(1) give the Court any discretion, when considering an paying party's application for an order, that the receiving party do commence detailed assessment proceedings?
In Awan, Master Brown consider this question, and concluded that the court does have some discretion as to whether to accede to a r.47.8(1)-(2) Application, but that discretion must be exercised with provisions' purpose in mind, which is to bring the costs claim to a conclusion within a reasonable time. At paragraphs 42 to 46, Master Brown in Awan said:
'It is correct that the provision is permissive in one sense because it makes clear that the paying party may apply for an order requiring the receiving party to commence detailed assessment proceedings within such time as the court may specify. The first use of the word 'may' is however directed to the act of applying, giving the paying party power to stop delay and thus bring about detailed assessment. The court also clearly has a discretion to order an unless order under subrule (2). But the terms of subrule (1) allow the paying party to apply "for an order requiring the receiving party to commence" proceedings and do not expressly give the court a discretion to refuse the application.
I agree that the fact that rules provided for an application to a judge rather than a court officer point to the court having some discretion. If it were otherwise, the rules would provide for the matter to be dealt with by a court officer. Further the rules do not say that the court must order the commencement of detailed assessment proceedings. I can thus see the force of the point that it must be implicit in the rule that the court has a discretion not to make such an order. Again, if were otherwise the rule would have said so. Albeit the rule is perhaps not quite as clear as it might be I am prepared to agree with Mr Lipson's analysis on this point to the extent of accepting that the court is not required to make an order for detailed assessment and there must some discretion.
That said, I do not think that there is a general discretion to be exercised in the way that [counsel for the r.47.8(1)-(2) Respondents'] was urging me to do. It seems that at the very least there must be a good reason why the Court should not make an order for the commencement of detailed assessment proceedings if an application is made,
There may, as I have recognised, be a good reason not to commence in accordance with the time limit in the rules. The three month time limit can be unrealistic in some cases. It seems to me perhaps obviously, that the court might not be obliged to make an order in those circumstances. Or at least it is perhaps conceivable there are circumstances where no order would be made. I have to say I find it difficult to imagine that in the ordinary case a court would not make some order for detailed assessment because the Court, even if it does not make an unless order, is going to want to ensure that there is some time limit applicable to the service of detailed assessment proceedings. In general the Court should not, in accordance with the overriding objective permit substantial delay. But I do accept that it is conceivable that there may be circumstances where it may not appropriate to compel a party by order the commencement of detailed assessment proceedings.
Certainly, however as Mr Lipson's research revealed, a number of judges - Master Kaye in Ineos Upstream v Persons Unknown [2023] EWHC 214 (Ch) in [114], and in Michael Wilson & Partners Ltd v Emmott [2025] EWHC 747 (Comm), HHJ Pelling KC, sitting as a judge of the High Court, appear to accept the provision exists in order to compel a party who has not served detailed assessment proceedings in time within, to compel them to do so, to enforce an obligation to do so. That, it seems to me, clearly is the purpose that underlies that provision. Whilst I am prepared to accept, as I say, that [counsel for the r.47.8(1)-(2) Respondents'] is right that the provision does not itself require that the Court make such an order, and if not obliged to do so, there must be some discretion, undoubtedly that discretion has to be exercised with its purpose in mind, which is to bring the costs claim to a conclusion within a reasonable time.' [words underlined are in italics in original (save for the last paragraph); bold added]
The reference to 'as I have recognised', was a reference back to what Master Brown had said, in Awan, in paragraph 38:
'There may be indeed be good reasons why a party is unable to serve a bill within three months. It can be an unrealistic period of time to prepare a bill in the high value cases that we sometime deal with.' In such cases the parties can agree extensions of time. It is perhaps surprising to me, and perhaps to others, how infrequently parties apply for an extension of time for service of bills. But parties do, sometimes I think, agree extensions of time. There is moreover no doubt, that the practice of parties is generally to agree that judgment rate interest does not run in a period of delay - as a reflection of a failure to commence within time. So, at least as I see it, the notion that the commencement is optional is not accordance with general practice and the way parties generally interpret the rules.'
Seemingly though: (a) the discretion is not a 'general discretion' (at least, not commonly interpreted as such); (b) the discretion is generally exercised in favour of granting the r.47.8(1)-(2) Application. Master Brown in Awan, said, at paragraph 51:
'For what it is worth, as I understand it, the provision is not commonly interpreted as giving rise to a general discretion. If an application is made it for commencement as I understand it will at least generally be made.'
Master Brown identified:
(1) a problem with refusing such a r.47.8(1)-(2) Application[15]. It would leave the interim order, the interim payment on account of costs order, enforceable, permanently in the sense of never being replaced by a final detailed assessment of costs order (in the absence of agreement between the parties on the quantum of the detailed assessment sum). It would, in practical terms, to refuse a r.47.8(1)-(2) Application, would convert the interim order, into a final order. Interim orders are not 'designed' to be final orders. Interim orders meet a different purpose[16].
(2) an alternative, in effect, to making a r.47.8(1)-(2) order. Varying the original order for costs, such as to provide for a summary assessment of costs. Variation being permissible on the basis of a material change of circumstances (Tibbles v SIG [2012] 1 WLR 2591 (Court of Appeal))(see Awan, paragraph 52; also, paragraph 53[17])
On the facts in Awan, Master Brown make the r.47.8(1)-(2) order (paragraph 55). He identified 3 factors[18], namely, the receiving party's prospective:
(1) costs associated with serving a Notice of commencement and a bill of costs;
(2) fees for request for detailed assessment (if there is a Points of Dispute - noting that, if the receiving party limited itself to the interim order sum, his might reduce the scope for disputes);
(3) concerned about the difficulties with enforcement against the paying party;
but even then, reasoned that he was 'not satisfied' that counsel for the r.47.8(1)-(2) Respondents had provided any good reason not to have a detailed assessment (paragraph 60).
Master Brown:
(1) acknowledged that the order sought would oblige the r.47.8(1)-(2) Respondents to undertake further steps, with costs implications. But, he said that he was '...not satisfied that they are as substantial or difficult or should weigh heavily against making of any order for commencement for detailed assessment.' (paragraph 60)
(2) said 'Many of the factors which are relied for not proceeding to assessment could be raised by any receiving party.' (paragraph 60);
(3) considered the delay between 20.10.17 detailed assessment order (20.1.18 - 3 month CPR prescribed detailed assessment commencement deadline) and 2.10.25 (the date of the hearing), a gap of c.8 years. But said '...even accepting that the passage of time is substantial in this case it is not to my mind a good or sufficient reason it [SIC] to make the order sought and to deprive the [r.47.8(1)-(2) Applicant] of the ordinary entitlement to the service of a bill and assessment.' (paragraph 60)
(4) considered the contention that the r.47.8(1)-(2) Applicant's pursuit of the r.47.8(1)-(2) Application, was:
(a) an abuse, because of the r.47.8(1)-(2) Applicant's: (i) very substantial delay; and (ii) conduct (paragraphs 64 and 65).
(b) considered the contention that r.47.8(1)-(2) Applicant had an ulterior motive for pursuiting the r.47.8(1)-(2) Application;
Master Brown concluded that:
(1) the objections to a r.47.8(1)-(2) order, put forward by the r.47.8(1)-(2) Respondents, were '...insufficient to outweigh the factors in favour of a detailed assessment.' (paragraphs 61). 'If the discretion were to be exercised having regard to the need to bring about finality it would certainly to my mind, would have to be exercised in the Applicant's favour.' (paragraph 61); and that
(2) as to point (4) above, about abuse, he '...was not persuaded that these considerations make any difference.' (paragraph 65). He said:
'As I read [Haji-Ioannou 1663], considerations of abuse now have little part to play in dealing with the delay in commencing detailed assessment proceedings. The case appears to indicate that there the provisions are a self contained scheme dealing with delay, with prescribed sanctions.' Delay, in the author's view, means: (a) the paying party faces the prospect of paying judgment rate interest; conversely, (b) the receiving party faces negative consequences, such as the the deprivation of interest (see paragraph 66).
On receiving party detailed assessment commencement delay, Master Brown did say he accepted that '...there must come a point, when the delay is so long that it would not be appropriate for detailed assessment to go ahead.' (paragraph 67). However, later, Master Brown said, at paragraph 82:
'There would be real difficulty, if [counsel for r.47.8(1)-(2) Respondent] were right if the court had the wide discretion [counsel for r.47.8(1)-(2) Respondent] argued that it did, in determining at what point the delay were such that a court was required to say that was long enough, the interim on account order should stand, and the order for detail assessment is be left lying - as it were - on the record. How would the discretion be exercised? What are the criteria by which it would be exercised? I do not see how the new rules in the CPR, which were intended to overcome problems under the RSC and reduce uncertainty and satellite litigation, could be interpreted do as to give rise to such a general discretion. That seems to be another reason why I should reject the [r.47.8(1)-(2) Respondent] argument.'
On the facts, before him (a c.8 year delay case) however, Master Brown said that '...that point has not been reached in this case, notwithstanding there has been substantial delay. It would not be unfair for this matter to proceed to detailed assessment nor is there any other reason why this matter could proceed to an assessment even now some years after the relevant work was done.'[19].
(3) the ulterior motive challenge was not sustainable. Master Brown said that 'It is not normally appropriate to consider an underlying motive for an application where an application, as it is here, is objectively justifiable.' (paragraph 79) and that 'the court generally does not have the means to for a view about this.' (paragraph 79) Acknowledging that there was, at the very least, a reasonable suspicion that the r.47.8(1)-(2) Applicant making the r.47.8(1)-(2) Application, as a way to defer enforcement of the interim order, Master Brown took the view that, '...[n]evertheless a paying party is normally entitled to see a Bill of costs before agreeing costs and in an appropriate case, to a detailed assessment.' (paragraph 79; see also paragraph 83)
(4) said that r.47.8 contained '...a self contained code for dealing with delay which puts the obligation on the receiving party to commence detailed assessment proceedings, and gives the paying party merely the option to enforce that.' (paragraph 80) and that 'It seems that under CR 47.7 there are difficulties with the paying party complaining about the delay, as it has the ability to bring it to an end. As the Court of Appeal indicated in [Haji-Ioannou 1663], the scheme worked very well.' (paragraph 81)
(5) an unless order was made (paragraph 87).
NO ISSUED R.47.8(1)-(2) APPLICATION - APPLICATION FOR COURT IMPOSED DETAILED ASSESSMENT COMMENCEMENT DEADLINE
CPR rules
Where:
(a) the paying party has not made an application in accordance with r.47.8(1)-(2); and
(b) the receiving party commences the proceedings later than the period specified in rule 47.7,
the court may disallow all or part of the interest otherwise payable to the receiving party under-
(i) section 17 of the Judgments Act 1838; or
(ii) section 74 of the County Courts Act 1984,
but will not impose any other sanction except in accordance with rule 44.11 (powers in relation to misconduct).
CPR r.44.11 (formerly numbered r.44.14), is entitled 'Court’s powers in relation to misconduct' and reads, so far as relevant:
'(1) The court may make an order under this rule where-
(a) a party or that party’s legal representative, in connection with a summary or detailed assessment, fails to comply with a rule, practice direction or court order; or
(b) it appears to the court that the conduct of a party or that party’s legal representative, before or during the proceedings or in the assessment proceedings, was unreasonable or improper.
(2) Where paragraph (1) applies, the court may-
(a) disallow all or part of the costs which are being assessed; or
(b) order the party at fault or that party’s legal representative to pay costs which that party or legal representative has caused any other party to incur.'
Rule 47.8(3) disallowance of interest and r.44.11 sanctions
In Less, Warren J at paragraph 71 said:
'It is true that if D did not in fact serve his Notice of Commencement on all Cs within the time-limit under CPR 47.7 he was in breach of the rules. However, the consequence is not automatic that costs must be disallowed either in whole or in part. The primary sanction is disallowance of interest and, indeed, any other sanction is prohibited save by the application of CPR 44.14.' [bold added]
The exact interrelationship between r.47.8(3) disallowance of interest and r.44.11 (formerly r.44.14) sanctions has proved problematic, and in need of clarification.
On this, first, the decision of Lindsay J in Haji-Ioannou 279 will be considered (and, we shall see, an appeal against Haji-Ioannou 279, to the Court of Appeal, was dismissed).
Haji-Ioannou 279 - the facts
In Haji-Ioannou 279, on 31.3.99, the defendant (the receiving party) received a costs order, subject to a detailed assessment if not agreed, in its favour against the claimant (the paying party). So the receiving party ought to have issued a notice of commencement, by 30.6.99 (Haji-Ioannou 1663, paragraph 5). In fact, the notice of commencement was not served until 1.7.04 (5 years later[20]). On 9.9.05, the paying party applied for relief, by way of: (a) a disallowance of interest; and (b) disallowance of a proportion of the receiving party's costs. On 26.9.05, at first instance, Costs Judge Seager Berry dismissed the paying party's application. The paying party appealed, and this appeal can before Lindsay J (the first appeal).
Haji-Ioannou 279 - first appeal
In Haji-Ioannou 279, Lindsay J said, at paragraph 10:
'It is convenient to speak of those last words of 47.8(3) - “but must not impose” onwards - as “the Proviso”...Before we go on to look at the CPR 44.14 referred to, it is as well to pause to consider the terms of 47.8. The power to disallow which it confers is exclusively as to one or other of the two kinds of interest to which it refers; it does not permit any disallowance of costs. But the sanctions available under 44.14 to which the Proviso refers relate (as we shall come on to) exclusively to costs and not to interest. The Proviso thus does not operate as a true proviso; it does not operate to exclude some sanction which, but for the Proviso, would have been capable of application under the body of the rule. Instead it serves to emphasise to the court the boundary - the disallowance of interest only - of the sanction available under 47.8(3). There cannot, in such a case, for example, be anything deducted from the amount of any sum of principal awarded to the receiving party in any judgment in his favour nor, say, can there be some qualifying of the terms of any declaration or other relief which he had obtained. It cannot sensibly be said where the pre-conditions of 47.8(3)(a) or (b) are met and there is a disallowance of interest, that no other sanction can then ever be imposed as that would be to stop at the words “but must not impose any other sanction” without paying regard to the remaining words “except in accordance with rule 44.14” (our emphasis)' [words underlined as in italic in original]
Lindsay J in Haji-Ioannou 279 continued, at paragraph 11:
'Section 18 of the 1838 Act makes an order for costs a judgment debt within the meaning of s 17 of the same Act – see Powell v Herefordshire HA [2003] 3 All ER 253 at 255 para 8. In the case at hand the Court of Appeal, had it paused until the CPR came into effect, could have provided for interest on costs to have run from some date other than the date of their award – see CPR 40.8 and 44.3(6)(g) – but as at 31 March 1999 no such power existed and the 1999 Order thus could not make any such special provision as to interest on costs. Accordingly interest on costs runs from the date of the 1999 Order. It runs from that date and not from either the beginning or the end of the assessment process. By delaying his commencement, the receiving party, at any rate where the paying party does not intervene under 47.8(1), thus, in the absence of a disallowance or concession as to interest, prolongs the period in respect of which the paying party would be required to pay interest. But the paying party has the remedy of 47.8(1) in his hands and could, of course, further or alternatively reduce his liability as to interest by making a payment on account. Where the receiving party suffers a disallowance of interest or makes a concession to the same effect there is a corresponding benefit to the paying party who, in any event, by reason of the receiving party's delay, has the benefit of having still in his hands such principal monies as, had the receiving party acted more promptly, would have had to be paid over to that receiving party. Delay on a receiving party's part can in such circumstances thus represent a self-inflicted wound on the receiving party and something of a gratuitous windfall to the paying party.
Lindsay J in Haji-Ioannou 279, then turned to the sanctions that may be imposed in accordance with r.44.14 (misconduct). After quoting r.44.14 (now r.44.11), Lindsay J in Haji-Ioannou 279 said, at paragraphs 12 and 13:
'Little is to be made of the word “misconduct” in the heading. It does not appear in the body of the rule. Moreover, it is very easy to imagine circumstances falling within 44.14(1)(a) where nothing fairly describable as “misconduct” has occurred. One would hardly describe as involving “misconduct” the case of, say, a litigant in person whose failure to comply with a rule is demonstrated to have been wholly referable to serious illness or serious accident and injury.
It is plain from its terms and it is common ground before us that 44.14 includes no provision for disallowance of either of the two classes of interest disallowable under 47.8; 44.14, so far as concerns disallowance under 44.14(2)(a), provides only for disallowance of costs.'
Lindsay J in Haji-Ioannou 279 went on to reject a number of argument put forward, Lindsay J rejected the argument that:
(1) there may be an inconsistency, or conflict, between r.47.8 and r.44.14 (now r.44.11). Lindsay J said '...one relates to disallowance of interest and the other to disallowance of costs but the former makes it clear that the possibility or fact of disallowance of interest does not of itself preclude the disallowance of costs.' (paragraph 14)
(2) '...before there could be a disallowance by reason of the receiving parties having failed, within 44.14(1)(a), to comply with a rule, practice or Court Order, it would have to be shown that such failure had caused some identifiable tranche of costs to the paying party and that it was only that tranche which then could be disallowed.' (paragraph 14). Lindsay J said, at least a reason was, '...there is no express reference to any causative connection being required in 44.14(2)(a), that there is...no necessity to imply any such requirement, that the draftsman shows, from the nature of the provisions he makes in 44.14(2)(b), that when he intends a causative link he knows how to provide one and that the expressio unius canon of construction therefore suggests that no causative link was intended under 44.14(2)(a).' (paragraph 14)
(3) '...where the only rule which the receiving party has failed to comply with is the three-month time limit of 44.7 then the only possible sanction is a disallowance of interest under 47.8 and not any disallowance of costs under 44.14.' (paragraph 15). Lindsay J observed that, '...had that been intended the Proviso would have stopped at the words “but not impose any other sanction” whereas, as we have already noted, they do not stop there but rather go on to refer to 44.14 sanctions being available. The concluding words of the Proviso would hardly have referred to 44.14 sanctions were they to be unavailable in all circumstances' (paragraph 15)
(4) where a Court imposes a r.47.8 disallowance of interest, as a matter of jurisdiction, the Court cannot go on to impose a r.44.14 (now r.44.11) disallowance of costs, save in exceptional circumstances (paragraph 16). Lindsay J reasoned that '...[h]ad that been intended one could reasonably have expected to see the Proviso concluding with words such as “… save, and only in exceptional circumstances, in accordance with rule 44.14” and to find some proviso in 44.14(1)(a) excluding its applicability, save in exceptional circumstances, where interest had been already or was to be disallowed by order of the court under 47.8. Nothing such is to be found expressed in either rule and, as we find no inconsistency between the two rules, we see no need to make any implications in order to avoid it.' (paragraph 16)[21]
A factor in whether to impose a sanction, under r.47.8(3), on the receiving party, is the fact the paying party did not deploy the option, always available to it after the 3 months has expired, to make a r.44.8(1)-(2) Application, and counter the receiving party's delay.
Haji-Ioannou 1663
As stated, Haji-Ioannou 279 was appealed to the Court of Appeal. In the Court of Appeal, in Haji-Ioannou 1663, Longmore LJ (with whom Arden LJ and Sir Andrew Morritt C agreed):
(1) said that the Court of Appeal intended to '...give some guidance as to how the discretion vested in the costs judge by CPR r 44.14(2)(a) should be exercised.' (paragraph 1; now r.44.11(2)(a)).
(2) said, 'It is the inter-relationship between rule 44.14 and rule 47.8 that lies at the heart of this appeal.' (paragraph 2);
(3) noted the basic breach by the receiving party. That the notice of commencement was not served until 1.7.04 (paragraph 6);
(4) recorded that 2 arguments, deployed by the paying party in Haji-Ioannou 279, were no longer pressed by the paying party, that:
(a) '...in the event of delay in the commencement of assessment proceedings, the only possible penalty was the disallowance of interest;' (paragraph 8)
(b) '...there was some sort of jurisdictional condition precedent to the exercise of the power to disallow costs under CPR r 44.14 to the effect that there had to be exceptional circumstances of some kind in the case.' (paragraph 8)
Longmore LJ remarked that, neither argument was pressed before the Court of Appeal, '...no doubt for the excellent reasons set out in the judgment of Lindsay J.' (paragraph 8)
(5) recorded that the paying party did maintain that, '...before any disallowance of costs could be made pursuant to rule 44.14(2)(a), it had to be shown that the failure to commence the detailed assessment in time had caused the costs (which were to be disallowed) to be incurred or had caused at any rate some costs to be incurred.' (paragraph 8)
As to this, Longmore LJ:
(a) noted that Lindsay J had rejected this argument, for 3 separate reasons plus a '...conceptual difficulty of understanding how delay in assessing costs already incurred can have caused such costs to have been incurred' (paragraph 8). On the point, Longmore LJ used somewhat ambigous language, but did agreed, it seems with Lindsay J's reasoning, but upheld the decision: '...in any event, for the simple reason that, whereas rule 44.14(2)(b) does in terms require a causative link when it is shown that a party is at fault (in the sense of being guilty of unreasonable or improper conduct) and an order is sought that that party or his legal representative pay costs, rule 44.14(2)(a) does not. It is only rule 44.14(2)(a) on which the [paying party] in this case relies.' (paragraph 8)
(6) agreed that there was '...no inconsistency between rules 44.14 and 47.8' (paragraph 9), but did find that was a 'certain tension between them' (paragraph 9). Longmore LJ:
(a) opined that 'A failure to commence detailed assessment within the three months required by rule 47.7 may fairly be described as a failure to comply with a rule and, therefore, at least be included in the general term “fails to comply with a rule” within the words in rule 44.14(1)(a).' (paragraph 9);
(b) resolved the tension by holding that, the correct interpretation must be that, not '...every failure to commence detailed assessment proceedings should be regarded as misconduct and permit the disallowance of costs as well as interest.' (paragraph 9). That the heading to r.44.11 (then r.44.14) gave a clue - using the word 'misconduct' in it. That this pointed '...to the nature of the court's discretion.' (paragraph 9). On this distinction, and when the discretion to make a r.44.11 (then r.44.14) order disallowing costs, should be exercised, Longmore LJ said:
'Some breaches of the rules can be more readily described as misconduct than others and the rules trust the costs judges, in the course of exercising their discretion, to recognise such misconduct when it occurs. It is difficult to be more helpful than to say that a “bad” breach of a rule viz (for present purposes) the rule requiring detailed assessment proceedings to be commenced within three months will enable a costs judge to exercise the power to disallow some or all of the costs which he is assessing. In other words there will usually have to be a breach of the rule which can properly be categorised as “misconduct”. An inordinate and inexcusable delay which has prejudiced the paying party may well come within this category; excusable, although inordinate, delay may not, especially if it has caused no prejudice. The important point is that, while a non-compliance with a rule, practice direction or court order is the only jurisdictional requirement for the exercise of the power contained in rule 44.14, it will usually be appropriate as a matter of discretion to consider the extent of any misconduct which has occurred in the course of such non-compliance. I deliberately refrain from saying anything further about the circumstances in which it may be appropriate for the powers under rule 44.14 to be exercised.' (paragraph 9)
(c) considered some authorities, namely: (i) In re Homes Assured Corpn plc [2002] 1 Costs LR 71[22]; (ii) Botham[23], and (ii) Less. In relation to Less, he:
(I) summarised it as: 'Warren J thought that “mere delay” would not be enough to justify the exercise of the power to disallow costs unless there were “exceptional circumstances”. Inordinate and inexcusable delay causing prejudice to the paying party might well constitute “exceptional circumstances”' (paragraph 11); and
(II) said 'I would not therefore disagree with what Warren J said, while preferring to say that it will only be in the event of a breach of the rule which can properly be categorised as misconduct that it will usually be appropriate to use the power to disallow costs.' (paragraph 11)
(7) returned to when, and how frequently, the Court should be imposing r.44.11(2)(a) (then r.44.14(2)(a)) disallowance of costs. Longmore LJ
(a) recorded the rival submissions from the parties on this, and said he preferred the submissions of the receiving party (set out in a footnote[24]);
(b) said that 'Of course delay is to be deprecated but where the relevant rule not only gives to the party at the receiving end of the delay the option of preventing further delay by himself taking the initiative but also spells out the normal sanction for penalising such delay (as rule 47.8 does), it seems to me that the court should be hesitant to exercise further powers to impose further penalties by way of reducing otherwise allowable costs.' [bold added] (paragraph 17). In essence, normalising disallowance of costs as a further sanction, would lead to '...a real danger of encouraging satellite litigation.' (paragraph 18)[25]
(8) on the facts in Haji-Ioannou 1663, Longmore LJ, referred to the 'good sense of the decision of Lindsay J' (paragraph 20) and that he could '...see no error in the exercise of his discretion by the judge' (paragraph 13). He agreed that there were no sufficient reasons for disallowing costs as well as interest (paragraph 13), stating that:
(a) two particular features in the case had to be borne in mind, when the discretion to impose a r.44.11(2)(a) (then 44.14(2)(a) disallowance of costs, was being considered.
(i) first - the paying party had always accepted that the delay has caused him no prejudice (paragraph 12);
(ii) secondly, '...even though the delay is inordinate, it is not inexcusable, since it was clear that no money to pay any assessed costs would be available until the claimant's Greek proceedings had come to some conclusion which has not yet happened.' (paragraph 12)
(b) Lindsay J had been correct that:
(i) the receiving party's delay was not such as to be wilful, deliberate or contumelious;
(ii) claimant as not being a model of cooperative expedition (which Longmore LJ said was a 'distinct understatement' (paragraph 13) and that that fact underlined Lindsay J's view that further sanction would be disproportionate and unnecessary.
The appeal in Haji-Ioannou 1663 was dismissed.
Costs
As to costs of a r.47.8(1)-(2) Application, see FN, wherein, Hamblen J said
'...the general position in relation to applications under CPR 47.8 is that the party who has not commenced detailed assessment within the requisite three months is ordinarily be [SIC] required to meet the costs of the application. This is pointed out in Cook on Costs at paragraph 28.19 which states as follows:
“Furthermore, the receiving party almost always ends up paying the costs of the application since there are few cases where the receiving party could not feasibly have a bill drawn and served notice within three months of the right to do so having arisen.”'[26]

[1] The labels 'paying party' and 'receiving party' have definitions in the CPR. Also defined is 'costs' and 'fixed costs' (amongst others). CPR r.44.1 is entitled 'Interpretation and application', and contains (so far as relevant):
'(1) In Parts 44 to 47, unless the context otherwise requires
“costs” includes fees, charges, disbursements, expenses, remuneration, reimbursement allowed to a litigant in person under rule 46.5 and any fee or reward charged by a lay representative for acting on behalf of a party in proceedings allocated to the small claims track;
...
“fixed costs” means costs, the amounts of which are fixed by these Rules;
...
“paying party” means a party liable to pay costs;
...
“receiving party” means a party entitled to be paid costs;'
[2] CPR r.44.6 is entitled 'Procedure for assessing costs' and reads:
'(1) Where the court orders a party to pay costs to another party (other than fixed costs) it may-
(a) make a summary assessment of the costs;
(b) give directions for the summary assessment of the costs to be made at a later date; or
(c) order detailed assessment of the costs by a costs officer,
unless any rule, practice direction or other enactment provides otherwise.
(Practice Direction 44 - General rules about costs sets out the factors which will affect the court's decision under paragraph (1).)
(2) Where a direction has been given under paragraph (1)(b), another judge who could have decided the claim or application which gave rise to the costs order may make the summary assessment if there is good reason to do so.
(3) A party may recover the fixed costs specified in Part 45 in accordance with that Part.'
Practice Direction 47, paragraph 8 is entitled 'Procedure for assessing costs: rule 44.6' and reads:
'8.1 Subject to paragraph 8.3, where the court does not order fixed costs (or no fixed costs are provided for) the amount of costs payable will be assessed by the court. Rule 44.6 allows the court making an order about costs either-
(a) to make a summary assessment of the amount of the costs; or
(b) to order the amount to be decided in accordance with Part 47 (a detailed assessment).
8.2 An order for costs will be treated as an order for the amount of costs to be decided by a detailed assessment unless the order otherwise provides.
8.3 Where a party is entitled to costs some of which are fixed costs and some of which are not, the court will assess those costs which are not fixed. The decision whether such assessment should be summary or detailed will be made in accordance with paragraphs 9.1 to 9.10 of this Practice Direction.'
'detailed assessment' is a defined term. CPR r.44.1 is entitled 'Interpretation and application', and contains (so far as relevant):
'(1) In Parts 44 to 47, unless the context otherwise requires
...
“detailed assessment” means the procedure by which the amount of costs is decided by a costs officer in accordance with Part 47;'
[3] Practice Direction 47, paragraph 8 is entitled 'Procedure for assessing costs: rule 44.6' and paragraph 8.2 reads:
'An order for costs will be treated as an order for the amount of costs to be decided by a detailed assessment unless the order otherwise provides.'
Master Brown, touched on this in Awan, where he noted, at paragraph 9;
'It is perhaps important to note that the costs were payable on the standard basis to be assessed if not agreed. The conventional order for costs, would be 'subject to detailed assessment if not agreed.' But nobody has really addressed me on this, may be because the assessment must mean detailed assessment in accordance with the 44PD.8. Indeed the Mr [SIC] judge would have reserved it to himself if he had intended to summary assessment. In any event nothing really turns on this. The point is that costs were to be assessed if not agreed.'
[4] CPR r.44.2 is entitled 'Court’s discretion as to costs' and r.44.2(8) reads:
'Where the court orders a party to pay costs subject to detailed assessment, it will order that party to pay a reasonable sum on account of costs, unless there is good reason not to do so.'
Payment on account of costs orders, are enforceable orders. In Patel v Awan [2024] EWHC 464 (Ch), Master Kaye gave judgment, ordering the sale of a property subject to a final charging order, the charging order securing payment of a payment on account of costs order ('POAOC order'). The POAOC order judgment debtors sought from Fancourt J, permission to appeal Master Kaye's decision. This was refused. In Awan v Patel [2025] EWHC 3332 (SCCO), Master Brown recorded, at paragraph 13, what happened:
'The Applicant and his wife subsequently sought to appeal that decision. On 19 July 2024 Fancourt J refused permission, stating that the Applicant and his wife had misunderstood the difference between an order for the payment of costs that had not yet been assessed and an interim payment. He held that there was no real prospect of establishing that an order for interim on account payment was not enforceable. He too made a number of remarks in his decision, but again...they were not integral to this decision. He noted what he referred to as to the 'checks and balances' in CPR 47 and said there was no requirement for a judgment creditor to pursue a detailed assessment, nor was there a requirement to make an interim payment conditional on the assessment machinery being invoked. These remarks also do not seem to me seems to be integral, or necessary, to the question whether the orders for interim on account payments are enforceable. He went on to say that the possibility of assessed costs being less than the amount of the interim payment did not justify refusing to allow the interim payment to be enforced in the interim.'
[5] The converse of this, is where the receiving party commences detailed assessment proceedings, before the receiving party is entitled to. PD47, paragraph 1 is entitled 'Time when assessment may be carried out: rule 47.1' and reads:
'1.1. For the purposes of rule 47.1, proceedings are concluded when the court has finally determined the matters in issue in the claim, whether or not there is an appeal, or made an award of provisional damages under Part 41.
1.2 The court may order or the parties may agree in writing that, although the proceedings are continuing, they will nevertheless be treated as concluded.
1.3 A party who is served with a notice of commencement (see paragraph 5.2 below) may apply to a costs judge or a District Judge to determine whether the party who served it is entitled to commence detailed assessment proceedings. On hearing such an application the orders which the court may make include: an order allowing the detailed assessment proceedings to continue, or an order setting aside the notice of commencement.'
[6] It must be said that the judgment in Awan v Patel [2025] EWHC 3332 (SCCO) suffers from some typographical errors/could have benefited from greater proofreading. Occasionally the 'receiving party' and 'paying party' appear the wrong way around.
[7] Rattan v Carter-Ruck Solicitors [2019] 5 WLUK 633 involved a delayed application for an assessment of a solicitors' bill of costs, in a dispute between a solicitor and the solicitor's own client. This involved consideration of CPR r.46. Different circumstances, to those under consideration in this article. Master Leonard said, at paragraph 66, when rejecting the relevance of: (a) Haji-Ioannou v Frangos [2006] EWCA Civ 1663; and (b) Less v Benedict [2005] EWHC 1643 (Ch)):
'...the court in Haji-Ioannou v Frangos & Ors and Less & Ors v Benedict was considering the effect of CPR 47.8 and CPR 47.14. Both provisions fall within the part of CPR 47 that apply, expressly, to costs payable by one party to another, meaning costs recoverable under an order. They prescribe the remedies available to a paying party where a receiving party fails in good time to serve a notice of commencement of detailed assessment proceedings or request a hearing. They are inconsistent with, and have no application to, a solicitor/client assessment governed by CPR 46.'
[8] CPR r.47.6 is entitled 'Commencement of detailed assessment proceedings' and reads:
'(1) Detailed assessment proceedings are commenced by the receiving party serving on the paying party-
(a) notice of commencement in the relevant practice form;
(b) a copy or copies of the bill of costs, as required by Practice Direction 47; and
(c) if required by Practice Direction 47, a breakdown of the costs claimed for each phase of the proceedings.
(Rule 47.7 sets out the period for commencing detailed assessment proceedings.)
(2) The receiving party must also serve a copy of the notice of commencement, the bill and, if required by Practice Direction 47, the breakdown on any other relevant persons specified in Practice Direction 47.
(3) A person on whom a copy of the notice of commencement is served under paragraph (2) is a party to the detailed assessment proceedings (in addition to the paying party and the receiving party).
(Practice Direction 47 deals with other documents which the party must file when requesting detailed assessment; the court’s powers where it considers that a hearing may be necessary; the form of a bill; and the length of notice which will be given if a hearing date is fixed.)
(Paragraphs 7B.2 to 7B.7 of the Practice Direction - Civil Recovery Proceedings contain provisions about detailed assessment of costs in relation to civil recovery orders.)'
See:
(1) PD47, paragraphs 5 to 12 on procedure;
(2) The relevant certificates in the bill must be signed by the receiving party or that party’s solicitor;
(3) Harris v Moat Housing Group-South Ltd [2007] EWHC 3092 (QB); [2008] 1 WLR 1578 High Court (Christopher Clarke J)
(4) Mainwaring v Goldtech Investments Ltd (No.2) [1999] 1 WLR 745, Court of Appeal
[9] For a (not particularly illuminating, it must be said) walk through of some of the CPR provisions, see Awan v Patel [2025] EWHC 3332 (SCCO), a r.47.8(1)-(2) application, wherein, under the heading 'The rules', Master Brown said, from paragraphs 15 to 20:
'The relevant rules are found, principally at least, in Civil Procedure Rule 47 which is headed 'Procedure for Detailed Assessment of Costs'.
CPR 47.6(1) provides::
(1) Detailed assessment proceedings are commenced by the receiving party serving on the paying party –
(a) notice of commencement in the relevant practice form;
(b) a copy or copies of the bill of costs, as required by Practice Direction 47; and
(c) if required by Practice Direction 47, (Rule 47.7 sets out the period for commencing detailed assessment proceedings.)
CPR 47.7. is in tabular form, but provides that where " the source of right to detailed assessment is a judgment, direction, order award or other determination, detailed assessment proceedings must be commenced within three months ".
[The r.47.8(1)-(2) appplicant] emphasised the word 'must' in the provision and argued that that means what [SIC] that there obligation was on the Respondents in this case to commence detailed assessment, an obligation that they failed to fulfil.
CPR 47.8 provides:
(1) Where the receiving party fails to commence detailed assessment proceedings within the period specified –
(a) in rule 47.7; or
(b) by any direction of the court,
the paying party may apply for an order requiring the receiving party to commence detailed assessment proceedings within such time as the court may specify.
(2) On an application under paragraph (1), the court may direct that, unless the receiving party commences detailed assessment proceedings within the time specified by the court, all or part of the costs to which the receiving party would otherwise be entitled will be disallowed.
(3) If –
(a) the paying party has not made an application in accordance with paragraph (1); and
(b) the receiving party commences the proceedings later than the period specified in rule 47.7, the court may disallow all or part of the interest otherwise payable to the receiving party under –
(i) section 17 of the Judgments Act 1838; or
(ii) section 74 of the County Courts Act 1984,
but will not impose any other sanction except in accordance with rule 44.11 (powers in relation to misconduct).
In Haji-Ioannou v Frangos & Others [2006] EWCA Civ 1663, a copy which Mr Awan produced to me, the Court of Appeal noted that the provisions, which came in with the Civil Procedure Rules, replaced what was described as to the much more cumbersome provisions in the RSC. The new rules were understood to avoid much of the satellite litigation associated with the earlier rules and were generally regarded as having proved effective. It is appropriate for me to mention this, way of passing comment only, but it might be understood that these new rules provided a largely self contained scheme for dealing with the question of delay in the commencement of detailed assessment proceedings.'
[10] The CPR r.47.7(1) table provides:

[11] PD47, paragraph 2 is entitled 'No stay of detailed assessment where there is an appeal: rule 47.2' (somewhat inaptly) and reads:
'An application to stay the detailed assessment of costs pending an appeal may be made to the court whose order is being appealed or to the court which will hear the appeal.'
[12] CPR r.2.11 is entitled 'Time limits may be varied by parties' and reads:
'Unless these Rules or a practice direction provide otherwise or the court orders otherwise, the time specified by a rule or by the court for a person to do any act may be varied by the written agreement of the parties. (Rules 3.8 (sanctions have effect unless defaulting party obtains relief), 28.3 (variation of case management timetable—fast track and intermediate track) and 29.5 (variation of case management timetable—multi-track), provide for time limits that cannot be varied by agreement between the parties).'
[13] CPR r.3.1 is entitled 'The court’s general powers of management' and r.3.1(1) and r.3.1(2)(a) read:
'The list of powers in this rule is in addition to any powers given to the court by any other rule or practice direction or by any other enactment or any powers it may otherwise have.
Except where these Rules provide otherwise, the court may-
(a) extend or shorten the time for compliance with any rule, practice direction or court order (even if an application for extension is made after the time for compliance has expired);'
[14] As observed by Master Brown in Awan v Patel [2025] EWHC 3332 (SCCO),
'There is no automatic sanction of strike out imposed for failure to apply within three months.'
[15] In Awan v Patel [2025] EWHC 3332 (SCCO) ('Awan'), Master Brown identified a particular and perhaps central difficulty with the r.47.8(1)-(2) Respondents' case (i.e their contention no r.47.8(1)-(2) order should be made). That was:
'As things stand the order for payment of £118,000 is for an interim on account payment. It is on account of the costs due on an assessment or a detailed assessment, if such costs have not been agreed. If costs are not agreed the payment is made on account of sums due on the detailed assessment. If there has been no detailed assessment - or no agreement, then I think [the r.47.8(1)-(2) Applicant] is right to say, effectively there have been no final determination or agreement as envisaged by the original costs order.
The £118,000 is payable on account of the sums which it was anticipated will be payable on assessment. The assumption which thus underlies the order is that receiving parties will progress the claim for costs to a detailed assessment. In this case they have not done so. It must follow from this that payment having been made because of the liability for costs arising on a detailed assessment - if not agreed, and there must be an assessment. So, it would follow from the terms if [SIC] the orders that I should order the service of notice commencement.
If I were to refuse this application, the interim on account payment order would remain, and continue to be an enforceable order. I put it to [counsel for the r.47.8(1)-(2) Respondents], not meaning to be pejorative, that in effect he was seeking to convert what is an interim on account order to a final order. And I am not persuaded by him that I have the ability to do that by the terms of the rules not least because the rules, at least in their express terms, envisage that orders will be made on an application under CPR 47.8(1) to enforce an obligation to commence detailed assessment.
Had it been anticipated there been a general discretion to make such an order it would, I think, be set out in express terms in the rule. It is not a necessary interpretation - the rule works well as it is ordinarily interpreted. Indeed if there were such an option to commence detailed assessment, it would substantially change the way costs are resolved with a far greater emphasis and time taken on applications for interim an account with the potential for substantial unfairness - and the potential for satellite litigation as to exercise of the discretion.
I think [the r.47.8(1)-(2) Applicant] is right about this, and clearly so....' (paragraph 47 to 51)
[16] In Awan v Patel [2025] EWHC 3332 (SCCO) ('Awan'), Master Brown said, at paragraphs 52 and 53:
'I accept and acknowledge the force of the point that [counsel for the r.47.8(1)-(2) Respondents] makes, that when a court makes an interim on account, the Court seeks to reflect the likely level of costs payable, following the guidance in [Excalibur Ventures LLC v Texas Keystone Inc [2015] EWHC 566 (Comm)]. That process is intended to assist the parties in determining or agreeing what those costs will be. But there may be real difficulties in the court forming a clear view as to the costs at a interim stage. The making of an interim on account order has another significant purpose, which is that it enables the receiving party to secure, by interim Charging Order or final Charging Order, or other such means, the sums which are going to be due to them by way of costs. It is an important step which enables the successful party to secure, as it were, the proceeds or the fruits of the litigation as it sometimes called. Recovering costs, as much as recovering damages, is important to a party and an a interim on account order may be important in securing an effective remedy. In the circumstance I do not accept the point made by [counsel for the r.47.8(1)-(2) Respondents] that if an interim on account payment cannot stand, as it were, as a final determination of the costs it would deprive the rules of their intended effect. It seems to me it plainly does not do so. The making of an enforceable order costs plainly does serve a useful purpose, even if, at the end of the day, there has to be a detailed assessment.'
[17] In Awan v Patel [2025] EWHC 3332 (SCCO), Master Brown said, at paragraphs 52 and 53:
'There are other ways of dealing with the problems that Respondents say arise - as is as demonstrated in Pipia v BGEO Group Ltd [2022] EWHC 846 (Comm). The court in that case, having made the standard order for detailed assessment of costs, there was no effective engagement on the part of the paying party in relation to the costs. Satisfised that that was a material change of circumstances, having regard to Tibbles v SIG [2012] 1 WLR 2591 (Court of Appeal), the Judge varied that order to provide for summary assessment of costs to avoid the receiving party having to apply for detailed assessment.
Indeed I suppose if it is clear that a party is not engaging or not going to be engaging on the question of costs, it might always be open to a court, when making its order as to costs, to say there should be a detailed assessment but to make provision in the event of particular circumstances the matter can also be dealt with by a summary assessment. So, the matter can return to that the court to determine the costs by a summary assessment.'
[18] In Awan v Patel [2025] EWHC 3332 (SCCO), Master Brown said, at paragraphs 56 and 59:
'I acknowledge, that there are costs associated with serving a Notice of commencement and a bill of costs. In large litigation, the costs of drafting heavy electronic bills can be substantial, but in this case the solicitors should have the papers, the attendance notes. They should have time ledgers. There should be, at least I would assume there are, solicitor/client invoices which have been delivered. I do not know. Solicitor/client invoices have to be a detailed, reasonably detailed record of the costs - the solicitors' fees and disbursements. They should set out of the costs that are due reasonably due. In any event I do not think the preparation of a bill in this case, even though it may be for more than £118,000, is really a very significant or costly undertaking at all.
I also appreciate that if Points of Dispute were served then there might need to be a fee paid for request for detailed assessment. Fees for detailed assessment have increased over years and are not insubstantial, albeit this this case would perhaps be at the more modest end of the scale In an appropriate case there could be exemption or remissions for such fees if the receiving parties entitled to them. In any event I take these fees into account but do not consider this factor, even making allowance for the possibility of a need for such fees being paid, as having much weight.
I appreciate too the [r.47.8(1)-(2) Respondents] have been concerned about the difficulties with enforcement, in the sense that that has been held up - at least by the appeal process. But, when properly examined, it seems to be important to note that the [r.47.8(1)-(2) Respondents] in this case, have secured by Charging Order, at the very least a substantial amount of their costs and interest. Although there is reference to there being other charges against the [r.47.8(1)-(2) Applicant] and his wife's property, I have not seen any evidence as to the extent of those charges as [counsel for r.47.8(1)-(2) Respondents] acknowledge, so I am satisfied that that it would be appropriate to proceed on the basis the costs of a cost claim and interest is likely to be fully secured. That puts the [r.47.8(1)-(2) Respondents] in a more advantageous position than many.
It would always be open to the [r.47.8(1)-(2) Respondents], in a Bill of Costs and in Notice of commencement, to limit their claim to the amount of the interim on account payment so the [r.47.8(1)-(2) Respondents] could in this case effectively to limit their claim to £118,000 plus interest. I understand that the case may have been costs budgeted. I do not know whether there might not be much room or prospect for putting in any substantial points of dispute- there may be. If no such points were served the [r.47.8(1)-(2) Respondents] would be entitled to a default cost certificate without the need for any costs assessment at all. If they are served, and costs cannot then be agreed a detailed assessment may not take long.'
Master Brown then added, at paragraph 60:
'In any event, I am not satisfied that [counsel for r.47.8(1)-(2) Respondents] has provided any good reason not to have a detailed assessment.'
[19] On delay, Master Brown in Awan v Patel [2025] EWHC 3332 (SCCO) ('Awan'), said:
(1) 'It is plain that mere delay is not ordinarily sufficient to strike a claim for want of prosecution. In Icebird Ltd v Winegardner [2009] UKPC 24, the Judicial Committee of the Privy Court confirmed that principles that apply to a consideration as to whether a claim should be struck out on grounds of want of prosecution are those set out in Birkett v James [1978] AC 297. The power to strike out should only be exercised where the court is satisfied that:
"Either (1) the default has been intentional and contumelious, e.g. disobedience to a peremptory order or conduct amounting to an abuse of the court. or (2) (a) that there has been inordinate and inexcusable delay on the part of the plaintiff or his lawyer, and (b) that such delay will give rise to a substantial risk that it is not possible to have a fair trial of the issues in action or that there is likely to be serious prejudice to the defendants either as between the themselves and the claimant and the plaintiff or between them and third party."' (paragraph 68)
(2) 'The courts are ... used to assessing of costs which relate to work done a long time ago. In [Michael Wilson & Partners Ltd v Emmott [2025] EWHC 747 (Comm)], the court was concerned with a delay of 12 years, a very long period of time. It is not in any event unusual for litigation to cover long periods and for the court to have to assess the reasonableness of work over such periods which and which was done many years ago.' (paragraph 69)
(3) 'Moreover, there is no reason to believe solicitors should have kept their papers. There are likely to be solicitor/client invoices. I was not told whether there was, but it would be surprising if they were not. There should in any event be the underlying papers. Most costs assessment are decided on the papers and do not require oral evidence or depend on the recollection of witness...' (paragraph 70; in the author's view, the first sentence of this paragraph, potentially is missing a 'not' between 'should' and 'kept').
(4) '...mere delay, substantial as it is, could not in my judgment justify this matter not proceeding to assessment. I am not satisfied that there is any serious risk that it is not possible to have a fair trial or fair assessment. The [r.47.8(1)-(2) Respondents] are not prejudiced or significantly so for the same reasons - indeed even if they were, it might be said it is of their own making.' (paragraph 70)
(5) 'Even if it could be said, has been delay in, on the part of [the r.47.8(1)-(6) Applicant], in making this application, I am not satisfied it amounts to an intentional or contumelious conduct.' (paragraph 71)
(6) it was very doubtful that r.47.8(1)-(6) Applicant was not aware of it until 2025 (paragraph 72), having been a litigation solicitor, but '[i]n any event, even if [r.47.8(1)-(6) Applicant] knew about the provision before 2025, the first point to make is that it merely gives the paying party the option to force the receiving party to commence proceeding it does not impose an obligation. So I do not think he could be said to be in breach of any order.' (paragraph 73)
(7) '...there is in my judgment an obligation the part of the paying party to apply for an assessment for reasons. At the very least the primary obligation is upon the receiving party to commence detailed assessment proceedings. It would seem to me to be difficult for a receiving party effectively to seek a strike out or dismissal of this application for want of prosecution given their own default. There may be problems with the retainer on the part of the receiving party, which can sometimes explain delay. That would come to light in detailed assessment, That is an unknown – and is a matter of speculation in this case. But I do not think I can ignore the obligation on the part of the Respondents to pursue their own claim,' (paragraph 74). Later, Master Brown in Awan said
'...I think it is clear that detailed assessment is not optional. The obligation is upon the receiving party to commence such proceedings. That must in any event weigh, it seems to me, in the balance in favour of the [r.47.8(1)-(6) Applicant] on this point. But it seems to me that I should exercise any discretion in favour even if the receiving parties are right in saying they had an option to commence detailed assessment.' (paragraph 77)
(8) '...independent of the reasons I have just given, I cannot ignore the problems that must be faced by litigants having lost proceedings. They may have limited resources available to them, and having to take to steps to force the other side to bring a claim, which obviously that party does not want to have to be face, may be problematic.' (paragraph 75)
(9) 'In short, I am not satisfied delay in making this application was contumelious, such that it would mean that any discretion could not be exercised in the favour, and that the delay can be described as abusive.'
[20] Though Longmore LJ added that '...although one could indulgently call it a delay of four years and three months if one counted time from the dismissal of the petition to the House of Lords.' (paragraph 6)
[21] In Haji-Ioannou v Frangos [2006] EWHC 279 (Ch); [2006] 2 Costs L.R. 315, Lindsay J added, at paragraph 16:
'We add that had exceptional circumstances been intended to be required then one might also have expected some amplification as to what circumstances were to be regarded as exceptional and yet further provisions might have been needed so that a party could not escape the need for showing exceptional circumstances by a timely concession as to interest such as might preclude a formal disallowance by the court under 47.8(3). Perhaps also provision would have been needed so that a disallowance of only a trivial amount of interest under 47.8(3) would not of itself and in the absence of exceptional circumstances bar the applicability of 44.14.'
[22] In Haji-Ioannou v Frangos [2006] EWCA Civ 1663; [2008] 1 WLR 144, Longmore LJ said, at paragraph 11:
'The decision of Park J in In re Homes Assured Corpn plc [2002] 1 Costs LR 71 depended largely on the provisions applicable to legal aid taxation which are different from those in play in the present case.'
[23] In Haji-Ioannou v Frangos [2006] EWCA Civ 1663; [2008] 1 WLR 144, Longmore LJ said, at paragraph 11:
'In Botham v Khan [2005] 2 Costs LR 259, where there were claims and cross-claims and Richards J held that not all blame was on one side, the judge referred to the need for misconduct and decided that on the facts no disallowance of costs should be made despite the lengthy delay that had occurred in commencing the detailed assessment.'
Readers might be interested to read what Lindsay J, in Haji-Ioannou v Frangos [2006] EWHC 279 (Ch); [2006] 2 Costs L.R. 315, said about Botham v Khan [2005] 2 Costs LR 259. at paragraph 23, Lindsay J in Haji-Ioannou v Frangos [2006] EWHC 279 (Ch); [2006] 2 Costs L.R. 315 said:
'Next we went to Botham v Khan and Lamb v Khan, [2004] EWHC 2602 (QB); [2005] Costs LR 259 per Richards J. At the end of lengthy trials Costs Orders were made in favour of the defendants but, either in respect of earlier or simultaneous orders for costs, there were Costs Orders going the other way in both actions. Both claimants lodged appeals in the actions. Seven years elapsed before Notice of Commencement had been served by the defendants as receiving parties. The claimants argued, inter alia , that the defendant's costs of *327 both actions should be disallowed under CPR 44.14 . Richards J set out the convoluted history of the matter, which included a “without prejudice” letter from the receiving party that appeared to extend time for the lodging of bills of costs but provided also that either side could bring the extension to an end by serving 14 days notice. Such notice was not given. As in our case, the receiving party did not claim interest – para 36. Richards J had no need to consider in detail the construction of CPR 47.8 or 44.14 as to the jurisdictions thereby conferred and did not do so; the case represents no other than an exercise of the 44.14 discretion on its own particular facts. It was, as the learned judge held – para 37 – far from being a case as to which blame lay on only one side. At para 44 the learned judge said:
“The conclusion I reach on this issue is that the delay, although deeply regrettable, ought not in the circumstances to cause me to impose any greater sanction than that already conceded by the defendant in the form of disallowance of interest.”
The case says nothing as to jurisdiction and, so far as concerns discretion, does nothing to suggest that any costs should have been or must now be disallowed in the case before us.'
[24] In Haji-Ioannou v Frangos [2006] EWCA Civ 1663; [2008] 1 WLR 144, Longmore LJ said, under the heading 'Wider considerations', at paragraphs 15 to 17:
'[Counsel for the paying party] made the forceful point that in most such cases it will be axiomatic that the receiving party should forgo interest for the appropriate length of time and, if no further penalty is imposed for inordinate delay, the bad old pre- CPR days will return when lengthy delays occurred without the courts taking adequate steps to penalise such delays. He relied further on the overriding objective that cases should be dealt with expeditiously (CPR r 1.1) and the dicta of Lord Woolf MR in Biguzzi v Rank Leisure plc [1999] 1 WLR 1926, 1933:
“it is also essential that parties do not disregard timetables laid down. If they do so, then the court must make sure that the default does not go unmarked. If the court were to ignore delays which occur, then undoubtedly there will be a return to the previous culture of regarding time limits as unimportant.”
In answer [counsel for the receiving party's] for the receiving party submitted that the position was more complex than [counsel for the paying party] suggested. First, the new CPR includes a specific provision (rule 47.8(1)) for the paying party to apply for an order requiring the receiving party to commence detailed proceedings within a specified time. This provision is considerably less cumbersome than the equivalent process in RSC Ord 62, r 29(3). Second it is a fundamental feature of the CPR that the parties should co-operate to achieve the overriding objective: CPR r 1.3. Third, the history leading to the enactment of the CPR showed that a more sophisticated approach than that of [counsel for the paying party] was appropriate. Under the RSC the only sanction usually available was to strike out the proceedings for inordinate and inexcusable delay; this gave rise to considerable satellite litigation on the question when and in what circumstances it was appropriate for the court to make such an extreme order. That was, as the Biguzzi case [1999] 1 WLR 1929, 1932 itself recognised, exacerbated by the provision in the CCR 1981 (SI 1981/1687) for an automatic strike-out if a relevant step was not taken by a relevant date. That led to even more satellite litigation in order to avoid such a draconian consequence. The intention of the CPR was that, in accordance with the overriding objective of dealing with cases justly, the penalty should be proportional to the offence. Usually that has meant that costs orders (payable within 14 days) will be imposed if an order or rule of court is not complied with. Where, therefore, the relevant rule provided for a particular time limit (here three months) and a particular sanction (the disallowance of interest) the court should not, even if permitted by the rule, be astute to introduce further sanctions other than for very good reason especially if such sanctions could only be imposed after a court hearing which could itself be categorised as liable to lead to satellite litigation.
I prefer [counsel for the receiving party's] submissions.'
[25] In Haji-Ioannou v Frangos [2006] EWCA Civ 1663; [2008] 1 WLR 144, Longmore LJ said, at paragraphs 18 to 20:
'There is, moreover, a real danger of encouraging satellite litigation. As Arden LJ observed in the course of argument, the prescribed sanction of the disallowance of interest is likely to be both comparatively uncontroversial and also calculable without unnecessary dispute. A deprivation of costs already incurred will be likely to be controversial in two quite separate ways. First, the opposing parties in the case are unlikely to agree what proportion in relation to what category of costs should be disallowed. Secondly once a deduction or diminution of costs is ordered, there is likely to be considerable controversy between a solicitor and his own client (who will often have paid his solicitors on an on-going basis and will be looking to recover the costs of having done so from the paying party) as to who should bear the primary responsibility for the deduction. On any view the onus, as a matter of practical reality, will be on the client to sue his solicitor for recovery of the fees already paid by him which, as the result of any order, he is now unable to recover. This is a potentially undesirable situation.
In these circumstances we asked our assessor whether there were approximately the same numbers of applications to costs judges on the ground of delay since the introduction of CPR as there had been pre- CPR . He has informed us that since the introduction of CPR there have been distinctly fewer applications in *151 relation to delays in assessment. I would infer from this that: (1) since the enactment of the provision for disallowance of interest, practitioners have generally seen the good sense of that penalty for the delay; (2) since the enactment of the provision whereby the paying party can apply for an “unless” order requiring the receiving party to commence detailed assessment proceedings within a specified time, paying parties have been making or threatening to make use of that provision; (3) these new procedures have been working comparatively well; (4) in this respect the CPR have had the beneficial result of reducing unnecessary contentiousness.
To my mind these considerations reinforce the good sense of the decision of Lindsay J and, for these reasons also, I would dismiss this appeal.'
[26] On the facts in FN v Secretary of State for the Home Department [2015] EWHC 3057 (QB), Hamblen J upheld a Master's decision to refused to set aside the Master's earlier cost order, a costs order the Master had made in favour of the paying party and against the receiving party, in respect to the costs of a r.47.8(1)-(2) Application.
To give more details. On 11.6.12, a Court of Appeal costs order ('COA CO') was made in favour of the receiving party and against the paying party (paragraph 2). The 3 month period ended 11.9.12 (paragraph 3). On 4.8.13, the paying party's solicitors gave the receiving party's solicitors a warning. On 22.9.14, the paying party issued a r.47.8(1)-(2) Application, without notice, seeking an unless order, that, unless the receiving party do serve a notice of commencement of detailed assessment proceedings etc. within seven days, the receiving party's costs would be assessed at nil (paragraph 9). The r.47.8(1)-(2) Application was put before the court to be dealt with on the papers (paragraph 10). The Master: (a) acceded to the r.47.8(1)-(2) Application, but gave a longer period for compliance, to 31.10.14; (b) awarded a costs order, in favour of the paying party and against the receiving party (paragraph 10). The order also stated, 'This order has been made without a hearing. The party affected by this order may, within ten days after it is served on him, apply by letter to the court requesting the court to stay, set aside or vary it.' The receiving party availed themselves of that liberty and applied to set aside the order (paragraph 11). In the event, they complied with the requirement to commence the detailed assessment before the matter came on for hearing before the Master, and by the time of that hearing, the only matter in dispute related to the Master's costs order (paragraph 11). The receiving party contended that the paying party, because the r.47.8(1)-(2) Application was made, without notice, under a duty to make full and frank disclosure, which the paying party had failed to discharge (in 5 ways), and that that the failure, was sufficiently serious, to justify the sanction of setting aside the Master's costs order. The Master refused, and the receiving partys appealed, contending the Master erred on this (paragraph 20).
Hamblen J dismissed the appeal. The Master had been entitled to find that there had been no breach of the duty of candour (there had been no material non-disclosure). Hamblen J did consider what he would have done - what sanction ought to have been imposed (if there had been a breach of the duty of candour), in particular, disallowing costs (particularly, the Master's costs order). On this, Hamblen J said that '...there is no reason in all the circumstances why there should be the sanction of setting aside the costs order in this case.' (paragraph 43). Hamblen J said '...I would not have been persuaded that the Master's conclusion that his costs order should stay in place was an erroenous conclusion. It would not, in my judgment, be an appropriate case for a costs sanction of this kind in circumstances where it was the appellants' own delay and breach of the rules and their further delay, following the clear warning given, which led to the application being pursued and thereby the cost incurred.'
