Cost Case Law Update - May 2025

Costs Case Law Update – May 2025

Welcome to the Kain Knight Case Law Update for May 2025, written by Colin Campbell. This edition brings you concise summaries of significant court decisions impacting civil litigation costs, professional conduct, and funding arrangements.

This month’s key cases explore the severe consequences of professional misbehaviour, including wasted costs orders against legal representatives for citing “manufactured” case law (Frederick Ayinde, R (on the application of) v The London Borough of Haringey). Colin also examines the intricacies of security for costs, including the unavailability of CPR 25 for a claimant against a non-party applicant (Jones v Persons Unknown & Ors), the court’s assessment of a bank’s “legal jeopardy” in refusing to return funds due to sanctions (Virgo Marine v Reed Smith), and the suitability of ATE policies as security (Lloyds Developments Ltd v Accor HotelServices UK Ltd).

Further significant rulings cover the timing and scope of Costs Management Orders (BDW Trading Ltd v Ardmore Construction Ltd), the definition and assessment of “costs thrown away” (Carl v Hawkins), and the application of Aarhus Convention costs protection (HM Treasury v Global Feedback Ltd). Additionally, we review developments in costs capping in the IPEC (Shorts International Ltd v Google LLC), the approach to issue-based costs orders and interim payments (Okuashvili v Ivanishvili), the approval of settlement agreements in class actions involving litigation funders (Merricks v Mastercard Inc), and the impact of narrowly missing a Part 36 offer (H & P Advisory Ltd v Barrick Gold (Holdings) Ltd).

Frederick Ayinde, R (on the application of) v The London Borough of Haringey [2025] EWHC 1040 (Admin) – 3 April 2025.

In a judicial review involving a housing matter, the defendant local authority failed in its application for relief from sanctions to enable it to participate in the trial. However, it was permitted to apply for a wasted costs order against the claimant’s solicitors and counsel on the grounds that the submissions that had been filed in support of the judicial review, had cited case law that had been “manufactured”.  Ritchie J held that putting fake cases into a pleading was wholly improper and such appalling professional misbehaviour justified a wasted costs order being made against both the solicitors and counsel.

Jones v Persons Unknown & Ors [2025] EWHC 977 (Comm) – 29 April

The claimant applied for security for costs under CPR 25 on the grounds that a non-party applicant had applied to set aside a summary judgment. Louise Hutton KC held that as the application was being made in existing proceedings and that as CPR 40.9 permitted a person who was not a party to apply to set aside a judgment, CPR 25 could not be deployed, since that rule only permitted a defendant (not a claimant) to apply for security for costs.

BDW Trading Ltd v Ardmore Construction Ltd [2025] EWHC 1063 (TCC) – 2 May. 

A submission by the claimant that the court had no power to make a costs management order (CMO) after a Costs and Case Management Conference had taken place, was rejected by Andrew Mitchell KC. He held that a CMO can be made at any time under CPR 3.15(2). It followed in the case before him, that subsequent revisions fell to be dealt with under CPR 3.15(A)  (budget variation) and he permitted adjustments for leading counsel’s fees on witness statements, disclosure and incurred costs but in sums that were below those sought.

Carl v Hawkins [2025] EWHC 1104 (Ch) – 7 May.

When dealing with “consequentials”, Simon Gleeson observed that the term “costs thrown away” was not strictly prescribed. There were cases where such costs were clearly identifiable such as on an application for an order which was later set aside. However, where a trial had to be adjourned and took place later, not all the costs would be wasted. Where that was the case, the court could not perform a summary assessment, and the costs would be subject to detailed assessment.

The Judge also held that there should be no costs consequences following the failure to send a pre-action letter as it was not possible to see how such a letter would have contributed to the efficient management of the proceedings, or in any reduction to the costs of resolving the dispute.

HM Treasury v Global Feedback Ltd [2025] EWCA Civ 624 – 13 May.

Below, Lang J had held that a claim for judicial review was an Aarhus Convention claim (see (see Article 9(3) Convention on Access to Information, Public Participation in Decision-Making and Access to Justice in Environmental Matters) falling within Part IX of CPR 46 and had ordered that the costs limits in CPR 46 should apply. The Court of Appeal reversed her decision. Part IX gave partial effect to Art.9(4) by imposing costs limits on Aarhus Convention claims. The Convention required each party to ensure that members of the public had access to administrative or judicial procedures to challenge acts and omissions by private persons and public authorities which contravened provisions of its national law relating to the environment. The challenge in question had amounted to allegations of breaches of public law principles and not to any breach of the country’s law relating to the environment or environmental law. Accordingly, it had fallen outside the scope of Art.9(3) of the Aarhus Convention, and any costs protection could only be considered through an application for a costs protection order.

Virgo Marine v Reed Smith [2025] EWHC 1157 (Comm) – 14 May.

Security for costs under CPR 25. The defendant firm had held $11.m in an escrow account with a third-party bank in relation to the sale of a vessel by the claimant. US sanctions subsequently imposed on the claimant led to the termination of the sale contract. The firm was instructed to return the $11m but the bank refused due the potential violation of the sanctions. The claimant sued for the return of the $11m against the firm which brought an additional claim against the bank alleging breach of contract in failing to comply with its instruction. The firm applied for security for costs of £6m under CPR 25.27. Foxton J dismissed the application.

Whilst there was reason to believe that the claimant would be unable to pay any costs order in the firm’s favour, the evidence that Bank would face real legal jeopardy in making a payment from a bank account within the  jurisdiction to the firm  to discharge a liability due to the firm arising by reason of an order of the court, was thin and unpersuasive.

Shorts International Ltd v Google LLC [2025] EWCA Civ 653 – 14 May.

Following the dismissal in the Intellectual Property Enterprise Court (IPEC) of a trademark infringement claim against Google,  Shorts applied for a costs-capping order for its appeal under CPR 52.19. Google cross-appealed for £200,000 for security for costs. Lewison LJ held the IPEC had been established to facilitate access to justice by small and medium sized enterprises, and that facilitation of justice was expressed in the rule as a need. That tipped the balance. The recoverable costs of the appeal and the cross-appeal were limited to £60,000, to be paid as security for costs, since by making the application for a costs capping order, there was reason to believe that Shorts would be unable to pay Google’s costs if the appeal failed.

Okuashvili v Ivanishvili [2025] EWHC 1267 (Ch) – 16 May.

To reflect the relative success or failures at trial, the parties contended for issue-based costs orders under CPR 44.2(6((f). Rajah J held that none of the issues upon which one party or another had failed were discrete and could be isolated. The fact that along the way the claimants scored some hits did not detract from the outcome or justify an issue-based order. It followed that the claimants would pay the costs of the applications of all the defendants, except the second. As against him, that the claim had been shorn of the claimant’s other proposed routes to the same result did not justify an issue-based costs order.

For interim payments, they were payable in a sum that erred on the side of caution, so that they would not exceed the costs recovered on an assessment. That was 50% for standard basis costs orders and 60% for indemnity basis, with stays of payment in respect of Georgian based defendants, where there was a risk of irremediable prejudice to the claimant if no stay was granted and the appeal turned out to be successful.

Lloyds Developments Ltd v Accor HotelService UK Ltd [2025] EWHC 1238 (TCC) – 20 May.

In a claim relating to agreements between Lloyds and Accor for the construction and management of a 290 bedroom hotel, it was agreed (Lloyds being in administration) that security for costs should continue to be provided, £2m having already been ordered. Lloyds submitted that £617,336 should be given by an ATE policy. Accor contended for a further £1,162,336. Constable J held that the policy did not provide equal protection as a payment into Court. By reason of the generality of wording, there was (at a minimum) a realistic risk of the insurer properly arguing that as a matter of construction, it would be under no liability in the case of fraud by the Claimant (or its principal or agents) in placing the policy.

In addition, the insurer would not pay any claim under the Endorsement for “Incurred Adverse Costs incurred after the Litigation Funding Agreement has been terminated”, but the LFA Litigation Funding Agreement had not been disclosed. Accor therefore did not know in what circumstances it might be terminated. Lloyds was given 10 days to refine the policy to meet these two areas of concern. Any dispute on the refinements would be dealt with by way of written submissions. The total security to be provided was £882,336.

Merricks v Mastercard Inc [2025] CAT 28 – 20 May.

The CAT (Roth J acting President) approved the settlement agreement reached between Mastercard and class representative (CR), and opposed by the litigation funder (LF), which argued that the £200m payment was too low. Of that sum, £100m was ringfenced for class members, who had six months to claim from the claims administrator. Of the other £100m, £45,567,946.28 was ringfenced as a minimum return to the LF with the remaining £54,432,053.72 available to give the LF its return, subject to any further sums that needed to be distributed if take-up exceeded 5%.

Certain of the LF’s costs and the CR’s costs needed to be assessed and a report as to their reasonableness would be undertaken by an independent costs expert on a solicitor and own client basis together with the fees of the experts. The CAT would then determine the costs in the light of the report.

H & P Advisory Ltd v Barrick Gold (Holdings) Ltd (Re Consequential Matters) [2025] EWHC 1330 (Ch) – 30 May.

The Claimants failed on their substantive contractual case but demonstrated that they were entitled to a restitutionary quantum meruit of US$2m. The Defendants had made a Part 36 offer on 5 May 2023 to pay US$2m plus US$230,000 interest accrued to date. Subsequent determinations made by Simon Gleeson about interest meant that the Claimant had failed to beat the offer albeit by a whisker. There was nothing unjust about the consequences of CPR 36.17(4) applying. The defendant was ordered to pay 50% of the claimant’s costs up to 26 May 2023 being the date of expiry of the relevant period under the rule, with the claimant to pay the defendant’s costs thereafter.
