A brewing legal rift in one of the UK’s largest consumer class actions has escalated, as litigation funder Innsworth Capital seeks judicial review of the £200m Mastercard settlement approved by the Competition Appeal Tribunal (CAT). Innsworth, which financed the long-running Merricks v Mastercard case, is contesting the tribunal’s distribution structure, claiming it unjustly limits the funder’s return to less than half its investment, while allocating over £30m to a third-party charity.
An article in the Global Legal Post reports that Innsworth’s challenge centers on the May ruling, which capped its return at £22.8m—just 0.5× its £45.6m outlay—while setting aside the remaining balance of a £54.4m discretionary fund for either top-up class member payments or donation to the Access to Justice Foundation (ATJF). Innsworth alleges the tribunal made legal and procedural missteps, including misapplying Australian case law and failing to account for the commercial risk it bore in a case once valued at £14bn.
The funder argues that a return of 1.5× was both contractually contemplated and supported by precedent, and that the tribunal denied it a fair chance to respond to the proposed settlement mechanics. Its filing calls attention to what it deems an “arbitrary and irrational” allocation that favors a charity over the party that funded the claim’s pursuit.
The timing of Innsworth’s action is notable, following the Civil Justice Council’s June 3 report urging statutory regulation of funders and a legislative fix to PACCAR. The outcome of this judicial review could influence how courts and legislators assess funder profits—and reshape expectations around post-settlement fund allocations in collective redress cases.
