The King’s Bench Division’s decision in Mew v General Dental Council [2026] EWHC 1116 (Admin) concerned an appeal against erasure from the Dentists’ Register following a Professional Conduct Committee determination that the appellant’s fitness to practise was impaired by reason of misconduct.
Background
Dr Michael Mew, a registered Specialist Orthodontist and the owner and principal practitioner at a private clinic offering treatment under the umbrella term “Orthotropics,” appealed to the Administrative Court against a determination of the Professional Conduct Committee (“PCC”) of the General Dental Council (“GDC”) dated 6 November 2024. By that determination, the PCC found Dr Mew’s fitness to practise impaired by reason of misconduct and ordered the erasure of his name from the Dentists’ Register. The appeal was brought under section 29 of the Dentists Act 1984.
The charges before the PCC related to advice and treatment provided to two young patients, referred to as Patient A and Patient B, between September 2013 and May 2019, as well as claims made in a YouTube video posted in September 2017. In broad terms, the GDC alleged that the Orthotropic treatment provided to both patients was not clinically indicated, that misleading claims had been made to the patients’ parents about the aims and benefits of the treatment, and that certain statements made publicly on YouTube were inappropriate and without adequate objective evidential foundation. Thirty charges were brought in total, with admissions made to seventeen of them either in advance or at the hearing.
Orthotropics is not recognised by the GDC as a speciality, nor is it available within the NHS. Its central premise, as advanced by Dr Mew, was that environmental factors rather than genetics were the predominant cause of malocclusion, and that early environmental intervention could prevent or improve malocclusion in growing children. Dr Mew described himself as “probably the world’s expert” in Orthotropics and acknowledged that it remained a controversial approach with a limited evidence base.
The PCC proceedings were substantial. There were no fewer than 46 hearing days spread across a two-year period from November 2022 to November 2024, with the matter having originally been listed in December 2021 but removed at Dr Mew’s request. The determination itself ran to 197 paragraphs across 75 pages. Expert evidence was heard from four experts: Mr Stephen Powell and Mr Keith Smith for the GDC, and Professor Daniele Garcovich and Professor Stephen Sheldon for Dr Mew. Joint expert reports were also prepared. The PCC preferred the evidence of the GDC’s experts, found the charges proved, and concluded that misconduct and impairment were established. Erasure was imposed as the appropriate sanction, together with an immediate order for suspension.
The appeal was heard over three days on 20, 21 and 22 January 2026 before Charles Bagot KC, sitting as a Deputy High Court Judge. Further written submissions were received through to 26 February 2026, with email communications continuing to 30 April 2026. A draft judgment was circulated on 8 May 2026, with the parties’ corrections and submissions on costs received on 13, 14 and 15 May 2026. The appeal was dismissed in its entirety. The documents before the court ran to over 8,500 pages, with an authorities bundle of 925 pages.
On the substantive grounds, the Deputy Judge found that the PCC’s determination was correct in all material respects and unassailable. The primary challenge, directed at the PCC’s approach to the competing expert evidence, was rejected. The remaining grounds, including challenges to specific charge findings, the approach to “The Jaw Epidemic” paper, the alleged failure to define “adequate objective evidence,” and the exclusion of open-source internet material from cross-examination, were each dismissed. The fresh evidence application, which sought to adduce the full Harvey Thesis and a cephalometric interpretation guide, was also refused on a notional basis, having been considered at the parties’ joint request to assist with the resolution of costs.
The Legal Framework
CPR 44.2 deals with the court’s discretion about whether to make a costs order and the factors it will take into account. CPR 44.3 guides the court as to the basis of assessment. Where standard basis costs are concerned, the court is to determine any doubt about whether costs were reasonably and proportionately incurred, or were reasonable and proportionate in amount, in favour of the paying party. The considerations which point towards costs being proportionate include whether they bear a reasonable relationship to the factors in CPR 44.3(5), including the value of the non-monetary relief in issue, the complexity, additional work generated by conduct, and wider factors such as reputational issues or public importance.
As for the procedure to adopt for the assessment, CPR 44.6(1) and PD 44.9.1 provide the court’s jurisdiction to conduct either a summary assessment or refer costs for a detailed assessment by a costs officer or judge. PD 44.9.1 provides that the general rule is that the court should make a summary assessment of costs at the conclusion of any hearing which has lasted not more than one day.
The Deputy Judge rejected the Appellant’s submission that it should be implied from that passage that summary assessments should not be made in cases where the hearing has lasted more than one day. The court retains a discretion summarily to assess costs following hearings lasting longer than one day and there is no presumption, let alone rule, against doing so. The Deputy Judge was fortified in that view by the White Book Editors’ guidance at paragraph 44.6.3, which states: “There is no rebuttable presumption against summary assessment in relation to costs where hearings last longer than one day. The exercise of the power to make a summary assessment should be considered in every case.”
The Deputy Judge also noted the guidance at PD 44.9.2 that there may be good reason not to conduct a summary assessment where, for example, the paying party shows substantial grounds for disputing the sum claimed for costs that cannot be dealt with summarily.
Costs Issues Before the Court
Following circulation of the draft judgment, the parties agreed that costs should follow the event in accordance with CPR 44.2(2)(a), with the Appellant to pay the Respondent’s costs of the appeal. That much was not in dispute. The costs issues requiring determination by the court were twofold: first, whether the quantum of the Respondent’s appeal costs should be resolved by way of summary assessment or referred to detailed assessment in default of agreement; and second, if summary assessment was the appropriate course, what the correct quantum of those costs should be.
The Respondent’s costs schedule had originally been served in October 2025, when the appeal was first listed but subsequently adjourned. That schedule claimed costs totalling £85,853.20. An updated schedule dated 12 May 2026 increased the sum claimed to £96,248.48. Prior to the costs determination, the Respondent made an open concession of £10,000 against the experts’ fees element of the claim, reducing the sum in issue to £86,248.48. The Appellant raised objections across a range of items within the schedule and opposed the court proceeding to a summary assessment at all.
A procedural issue arose on the morning of handing down, when a dispute emerged between the parties as to whether there had been agreement for the court to be shown recent correspondence containing offers on costs. The Appellant contended that no such agreement had been reached and submitted that the court could not fairly conduct a summary assessment having been exposed to the parties’ respective offers. The Respondent maintained that agreement had been given. The Deputy Judge found it unnecessary to resolve that factual dispute in order to determine the costs issues, holding that judges are routinely required to put matters out of mind (such as documents seen de bene esse or offers disclosed in costs management hearings) and that he was able fairly to conduct a summary assessment notwithstanding his awareness of the offers.
An additional procedural point arose from the Appellant’s submission that, because the draft judgment had been embargoed, its content had not been communicated to Dr Mew by his legal representatives, and it had therefore not been possible to take instructions from him on costs. The Deputy Judge rejected the premise of that submission, noting that the embargo expressly permitted disclosure of the draft and its substance to the parties themselves and their legal representatives, and that there was accordingly no bar on sharing the draft with Dr Mew or taking his instructions.
The Parties’ Positions
Summary assessment versus detailed assessment
The Appellant opposed summary assessment on a number of grounds. It was submitted that, as the appeal hearing had lasted more than one day, the general rule in PD 44.9.1 pointed away from summary assessment. The Appellant also contended that there were multiple areas of the costs schedule requiring further interrogation and the provision of additional detail, and that the objections raised could not fairly be dealt with summarily. A further submission was advanced to the effect that, because the draft judgment had been embargoed and instructions had not been taken from Dr Mew, a summary assessment was procedurally inappropriate. Finally, the Appellant argued that the court’s exposure to the parties’ offers on costs meant that a fair summary assessment could not be conducted.
The Respondent’s position was that the court retained a discretion to conduct a summary assessment regardless of the duration of the hearing, and that the overriding objective supported resolving the costs of the appeal within the judgment rather than deferring them to detailed assessment. The Respondent pointed to the fact that the updated schedule of 12 May 2026 represented only a modest increase on the October 2025 schedule, of which the Appellant had had considerable notice, and that the schedule itself provided the expected level of detail and breakdown. The Respondent had also made an open concession of £10,000 on the experts’ fees, which was characterised as a realistic and sensible approach rather than an acknowledgement that the remaining costs were disproportionate.
Quantum
The Appellant challenged a range of items within the Respondent’s schedule, including the level of experts’ fees, the time costs associated with the experts and their reports, the time spent on producing the costs schedule, and the overall number of items detailed in the schedule of work done on documents (95 separate items being said to be indicative of excess). The Appellant declined to file or serve a schedule of his own costs and declined an invitation from the Respondent to do so for the purpose of contextualising the objections raised.
The Respondent maintained that the costs claimed were reasonable and proportionate having regard to the relevant factors under CPR 44.3(5), including the value of the non-monetary relief in issue, the complexity of the underlying proceedings, the additional work generated by the conduct of the litigation, and the wider reputational and public interest considerations. Particular emphasis was placed on the reasonableness of Counsel’s fees, given the nature and duration of the underlying PCC proceedings, the complexity of the appeal, and the need for complete mastery of 46 days of hearings and over 8,500 pages of documents.
The Decision
The Deputy Judge determined that the appropriate exercise of his discretion was to proceed summarily to assess the costs of the appeal, rather than deferring them to detailed assessment in default of agreement. Whilst he recognised that a referral to detailed assessment would be the normal order following a hearing of more than one day, it was not an invariable rule or presumption. Applying the rules and the overriding objective, several factors pointed in favour of summary assessment.
First, the Deputy Judge was well placed, having heard and determined the appeal via a detailed judgment, to conduct a summary assessment. He had considerable experience of costs and summary assessment, both as a Deputy High Court Judge and when sitting as a Deputy King’s Bench Master. The scale of the costs pointed towards summary assessment, given the amount claimed by the Respondent for the appeal was in five figures, not a substantial six-figure sum or more.
Second, whilst the Appellant complained that he had only about one day to review the Respondent’s updated costs schedule dated 12 May 2026, this had to be seen in the context that this was an update to a schedule served in October 2025, when the appeal was previously listed but adjourned. That earlier schedule already particularised almost 90 per cent of the costs claimed. The October 2025 schedule claimed costs totalling £85,853.20 whereas the May 2026 schedule increased that sum to £96,248.48 (before the £10,000 concession). The Appellant had therefore had an appropriate time period to consider the costs and could reasonably have anticipated that the adjourned hearing would produce a modest increase to the sum claimed.
Third, the Deputy Judge did not accept the Appellant’s assertion that there were multiple areas of the Respondent’s costs schedule which required interrogation and the provision of additional detail. The whole ethos of summary assessment is to avoid that sort of process and the attendant costs and delay, when this can fairly be done. Having scrutinised the Respondent’s schedule, it provided the expected detail and breakdown and, subject to certain adjustments, there was nothing in it which the Deputy Judge considered on the face of it to be disproportionate or unreasonable.
Fourth, and most fundamentally, the Deputy Judge bore in mind that these proceedings related to conduct between 2013 and 2019, now between 7 and 13 years ago. It was in accordance with the overriding objective to resolve all consequential matters within the judgment, rather than deferring the resolution of the appeal costs to further negotiation or, more likely, detailed assessment. The parties’ positions on costs were far apart. The Deputy Judge was pessimistic that simply allowing further time would result in an agreement on the amount of costs. It was probable that further costs would be incurred in proceeding at least part way towards a detailed assessment, which would swiftly become disproportionate to the sums involved, generate additional costs, and entrench the parties’ polarised positions further.
The Deputy Judge also noted that, notwithstanding the importance of the matter to the parties and the public interest in professional regulation, the underlying disciplinary proceedings had already taken up more than their fair share of the tribunal and court system’s limited resources. The PCC proceedings had occupied 46 hearing days spread across a two-year period. The Deputy Judge observed that this duration was manifestly disproportionate and that, with hindsight, the PCC should have exercised considerably more active case management, evidential control, and trial timetabling. Whilst the Appellant opposed the court proceeding to a summary assessment, it was in the Appellant’s interests, as much as the Respondent’s, to draw this protracted matter to a close. It would be doing the Appellant no kindness to permit him to spend further time, energy and money in disputing the appeal costs which he was to pay.
Quantum
As for the quantum of costs, with the Respondent’s open concession against the experts’ fees claimed of £10,000, the sum claimed totalled £86,248.48. The Deputy Judge bore in mind the Appellant’s various objections across a range of the amounts claimed. The Appellant had chosen not to file or serve a schedule of his costs and had declined an invitation by the Respondent to do so in order to contextualise the objections made. The Deputy Judge inferred that the Appellant’s costs of the appeal were greater than those claimed by the Respondent (the Appellant’s experts having, as the Deputy Judge understood it, worked pro bono), which would not be surprising assuming he was privately paying and as he was advancing the appeal, rather than responding to it.
The Deputy Judge noted that the Respondent’s solicitors’ blended hourly rate claimed of £138 for all fee earners involved was below the guideline rate, even for a Grade D fee earner of £146 (London Band 3), let alone that for Grade A of £319. This no doubt reflected negotiations around lower agreed panel rates in return for a regular flow of GDC work. This relatively modest hourly rate mitigated areas where, had the rates been significantly higher, the numbers of hours claimed would have pushed the overall costs claimed in differing categories up to amounts which would potentially have been disproportionate and unreasonable.
After making what he considered to be an appropriate further overall adjustment downwards for experts’ fees consequential on the Appellant’s application to admit fresh evidence, as well as reducing somewhat the solicitors’ time costs relating to the experts and producing the costs schedule, the Deputy Judge reached an overall figure of £75,000 (inclusive of VAT), before examining the other categories of costs further.
Nearly half of that amount related to Counsel’s fees for the appeal inclusive of VAT. The Deputy Judge disagreed with the Appellant’s contention that Counsel’s fees of £30,450 before VAT for appearing at this three-day appeal as well as preparing for it and drafting the written documents, even before factoring in the adjournment of the original listing in October 2025, were disproportionate and unreasonable. Those fees consisted of a brief fee of £28,000, plus two refreshers at £1,000 each, with a modest uplift of £450 which, whilst not explicitly broken down, may have reflected the adjournment of the original listing and a modest amount of time reading back in.
The Deputy Judge considered that no realistic objection could be taken to such fees in the circumstances. Counsel for the Respondent was a leading junior of considerable experience specialising in regulatory work. The underlying proceedings were complex, very lengthy, hard fought and document heavy. All of those factors applied to the appeal, save that at three days, it was not particularly lengthy. That said, the parties had suggested that four days of pre-reading time for the court were necessary (although in the event the necessities of listing meant that it only had one day). Extensive and diligent preparation had plainly been carried out by both parties’ Counsel. That had to be seen in the context that it was necessary for Counsel to have a complete mastery of all the issues, the extensive documents and of 46 days of hearings before the PCC. It was also necessary to distil those lengthy proceedings, the wide-ranging grounds of appeal and the Appellant’s painstakingly detailed submissions into a detailed and convincing written and oral response on behalf of the Respondent. Much was at stake for both parties and there were the wider interests of reputation and the public importance in the proper pursuit of regulatory proceedings. Counsel’s fees claimed were eminently reasonable and proportionate.
As for the Respondent’s solicitors’ time costs, a number of the same considerations also applied in justifying detailed and time-intensive preparation. Other than in relation to expert evidence and time on producing the costs schedule, the Deputy Judge did not consider that the sums incurred were disproportionate or unreasonable, whether standing back and looking at the global amount or considering the breakdown.
The Appellant had complained about the 95 separate items detailed in the schedule of work done on documents, as indicative of excess. In the Deputy Judge’s view, one needed to delve beyond the mere number of items to see that this reflected an admirable attempt at transparency in breaking down tasks into individual components, many of which were less than an hour in duration and reflecting appropriate delegation most (but not all) of the time. The overall total number of hours spent on documents by all fee earners combined was 179.5. Given the relevant factors in relation to the appeal, subject to the points around time on expert evidence being somewhat too high, there was nothing notable or objectionable about the time spent. This reflected work over a period of more than a year from the Appellant’s Notice being served to the substantive hearing, with additional work on consequential matters when the draft judgment was received.
The Deputy Judge made a further downward adjustment, beyond the concession of £10,000 made by the Respondent, to the experts’ fees and solicitors’ time costs on dealing with the experts and their reports, as well as a reduction to the time costs in relation to preparation of the costs schedule which, whilst a complex exercise, appeared on the high side.
For all those reasons, the reasonable and proportionate costs of the appeal were summarily assessed at £75,000. This sum included VAT of £6,090 on the Counsel fee element only (VAT was not claimed on any other aspect), with the Counsel fee before VAT being £30,450. The Appellant was ordered to pay to the Respondent the total sum of £75,000 for the appeal costs.
Whilst CPR 44.7(1) provides that the standard period for the payment of a costs order is 14 days from the date of the order, the Deputy Judge allowed an additional 14 days (28 days in total) for the Appellant to pay the sum ordered, to ensure fairness to the Appellant in making arrangements to pay. The sum was ordered to be paid by 4pm on 12 June 2026.
