The Technology and Construction Court’s decision in Matière SAS v ABM Precast Solutions Ltd [2025] EWHC 2030 (TCC) establishes that Part 36 offers demanding “total capitulation” on multi-million pound counterclaims may not attract full indemnity costs consequences.
Background
The dispute arose from a Consortium Agreement between the French claimant, Matière SAS, and the defendant, ABM Precast Solutions Ltd. In December 2021, Matière issued proceedings to recover £373,295.06 in unpaid invoices. ABM’s Defence and Counterclaim, served in February 2022, partially admitted the debt, acknowledging £157,241.91 was due subject to set-off. The remainder of the claim was not admitted. ABM counterclaimed for damages for breach of express obligations of good faith under the Consortium Agreement and a subsequent Collaboration Agreement. The counterclaim was initially valued at approximately £4.8 million but was later amended to £18.92 million, alternatively £16.62 million.
By the time of the trial, ABM had admitted all but £35,000 of Matière’s claim. The court’s liability judgment, handed down on 11 June 2025, found in favour of Matière on the claim, awarding the full sum of £373,295.06 plus interest. The counterclaim was dismissed in its entirety.
A significant feature of the procedural history was a Part 36 offer made by Matière on 4 April 2022. This offer proposed settling the entire proceedings, including the claim and counterclaim, for a single payment of £350,000 to be made to Matière. The offer was expressed to have the consequences set out in CPR Part 36. ABM did not respond to this offer. A further Part 36 offer was made by ABM on 17 September 2024, shortly before trial, in which it offered to accept £5 million to settle the proceedings.
Costs Issues Before the Court
The court was required to determine the consequential matters arising from its liability judgment, with the primary focus being the appropriate costs orders. The central issue was whether Matière was entitled to the full beneficial consequences under CPR 36.17(4) as a result of its April 2022 Part 36 offer. This included claims for indemnity costs from the expiry of the offer’s relevant period, enhanced interest on both the damages awarded and costs, and an additional 10% uplift on the damages sum. A further issue was whether, in the alternative, the court should make an issue-based or proportionate costs order to reflect ABM’s success on certain sub-issues at trial and Matière’s conduct. Finally, the court was asked to determine the appropriate rate of interest on sums awarded and to rule on Matière’s application for a substantial payment on account of costs.
The Parties’ Positions
Matière argued that its April 2022 offer was a valid Part 36 offer and that it had achieved a result more advantageous than the terms of that offer. It contended that the full consequences of CPR 36.17(4) must follow unless ABM could demonstrate it would be unjust, a burden it characterised as a “formidable obstacle”. Matière submitted that the offer was a genuine attempt to settle the entire proceedings and that ABM had sufficient information to evaluate it at the time it was made. It sought indemnity costs from the expiry of the relevant period, the maximum 10% enhanced interest, the 10% uplift on damages, and a payment on account of 95% of its budgeted costs.
ABM accepted that the Part 36 offer was valid in relation to the claim and that Matière was therefore entitled to the 10% uplift on damages and enhanced interest on the claim. However, it contended that the offer was not a genuine attempt to settle the proceedings in respect of the counterclaim. ABM argued that an offer of ‘nil’ for a counterclaim valued at millions was a demand for total capitulation. It further submitted that, applying the principles of CPR 44.2, the court should make a proportionate costs order and reduce Matière’s costs of the counterclaim by 70% to reflect its success on certain issues (scope of duty and findings of breach) and to mark the court’s disapproval of Matière’s dishonest conduct. ABM also argued that the maximum 10% enhanced interest rate was inappropriate and proposed a rate of 4% above base rate.
The Court’s Decision
The court conducted a detailed analysis of whether it would be unjust to apply the full Part 36 consequences. It found that the April 2022 offer was a genuine attempt to settle the *claim*, representing a concession of approximately 12% of its value. However, it was not a genuine attempt to settle the *counterclaim*. The offer of ‘nil’ for a multi-million pound counterclaim amounted to a demand for total capitulation. The court noted that whilst Matière was ultimately successful in defending the counterclaim, it could not have been so confident of its prospects at the time of the offer that a nil valuation was justified, particularly given the court’s subsequent findings that Matière had acted dishonestly and in breach of its duties.
Consequently, the court held it would be unjust to apply the indemnity costs consequence of CPR 36.17(4) to the costs of the counterclaim. Matière was awarded its costs of the claim on a standard basis up to the expiry of the relevant period (25 April 2022) and on an indemnity basis thereafter. Its costs of the counterclaim were awarded on a standard basis throughout.
The court rejected ABM’s argument for a 70% reduction in costs under CPR 44.2. It found that the issues on which ABM succeeded (scope of duty and breach) were merely stepping stones to establishing its loss of chance claim, on which it failed entirely. There was significant overlap in the evidence between breach and causation, and ABM did not succeed on all its alleged breaches. The court also declined to reduce costs to mark its disapproval of Matière’s conduct, finding the dishonesty was not at the most egregious level and did not materially fuel the dispute or lengthen the trial beyond what was necessary.
On interest, the court awarded Matière the 10% uplift on the principal sum (£37,329.51) as provided for by CPR 36.17(4)(d). For the period before the relevant date, pre-judgment interest on the claim was awarded at 4% above base rate. Enhanced interest under CPR 36.17(4)(a) was awarded on the principal sum from the relevant date, but the court exercised its discretion to set this at 7% above base rate, not the maximum 10%. Enhanced interest on costs under CPR 36.17(4)(c) was also awarded at 7% above base rate, but only for the costs of the claim from the relevant date. Interest on the costs of the counterclaim was awarded at 2% above base rate.
On the application for a payment on account of costs, the court ordered ABM to pay 90% of Matière’s approved budgeted costs, amounting to £935,000. Interest on this payment was set at 2% above base rate. The costs of the consequential hearing were deemed to be part of the general costs of the proceedings and were subsumed within the overall costs order.
Key Takeaway
This decision reinforces that Part 36’s protective regime cannot be manipulated through offers that demand total capitulation on substantial claims. Practitioners should ensure settlement offers involve genuine concessions across all aspects of disputes to secure full Part 36 benefits.
