Adam Gerchen Discusses His Approach to Litigation Finance

Public
The Legal Services Board (LSB) has unveiled a new consumer‑protection initiative to address mounting concerns in the UK legal market linked to volume litigation, law‑firm consolidators and unregulated service providers. An article in Legal Futures reports that the regulator cited “clear evidence” of risks to consumers arising from the dramatic growth of volume litigation, pointing in particular to the collapse of firms such as SSB Law.
Legal Futures reports that under the programme, the LSB will explore whether the current regulatory framework adequately protects consumers from harm in mass‑litigation contexts. That includes examining: whether all litigation funding – especially portfolio funding models – should fall under the supervision of the Financial Conduct Authority (FCA); whether co‑regulation arrangements should be established between the FCA and the Solicitors Regulation Authority (SRA); and whether the list of reserved legal activities needs revision to account for the rise of unregulated providers and AI‑enabled legal services.
On the law‑firm side the initiative spotlights the consolidation trend — especially accumulator or “consolidator” firms backed by private equity and acquiring large numbers of clients. The LSB flagged risks around viability, quality of client care and short‑term investor‑driven growth at the expense of compliance and long‑term service stability.
For the litigation‑funding sector, the message is unmistakable: the regulator will be more active in mapping the relationships between funders, law firms and client outcomes. It intends to use its market‑intelligence function to monitor whether misaligned incentives in the funding‑chain may harm consumers, and to obtain data from frontline regulators where necessary.
Veteran solicitor-campaigner Walter Merricks is poised to assume the role of class representative in a major collective action against rail operator Govia Thameslink Railway, following the death of the previous lead claimant. The case — brought under the opt-out regime before the Competition Appeal Tribunal (CAT) — alleges anticompetitive fare charging that harmed passengers traveling without a London Travelcard.
An article in the Law Society Gazette states that Merricks has formally applied to take over from former class representative David Boyle, who passed away earlier this year. The transition raises “a number of complex and difficult issues,” given the opt-out nature of the proceeding and the procedural demands of the UK’s evolving collective redress framework.
The move comes amid broader tensions between Merricks and his former litigation funder, Innsworth Capital. That dispute centers on the earlier £200 million settlement of Merricks’ landmark claim against Mastercard. Though the CAT approved the settlement, Innsworth launched a judicial review and initiated arbitration proceedings to challenge the allocation of proceeds, arguing its entitlement to a larger portion of the award. Merricks has been openly critical of the funder’s conduct, calling its approach an “embarrassment” and warning it could undermine public trust in third-party funding.
For the rail case, Merricks has retained Wilkie Farr & Gallagher as counsel. His application to replace Boyle as class representative is currently before the tribunal and will be considered at a hearing in January 2026.
In a major breakthrough for cross-border group litigation, Pogust Goodhead has secured a resounding victory in its long-running claim against mining giant BHP over the 2015 collapse of the Fundão tailings dam in Mariana, Brazil. The UK High Court has ruled BHP liable for the disaster, which killed 19 people and unleashed a wave of toxic sludge through the Rio Doce basin, displacing entire communities and leaving lasting environmental damage.
According to Non-Billable, the ruling confirms BHP’s liability under both Brazilian environmental law and the Brazilian Civil Code. In rejecting the company’s jurisdictional and limitation defenses, the court made clear that English law recognizes the right of over 600,000 Brazilian claimants to pursue redress in UK courts. The judgment underscores BHP’s operational and strategic control over the Samarco joint venture and found that the company was aware of critical dam defects more than a year before the collapse. The attempt to distance itself through the argument of being an indirect polluter was also dismissed.
This outcome is a critical milestone in one of the largest group actions ever brought in the UK. A trial on damages is now scheduled for October 2026, with case management proceedings set to resume in December.
The win comes amid internal turbulence at Pogust Goodhead, including recent leadership changes and reported tensions with its litigation finance backers, but the firm remains on course to press forward with what could be a multibillion-dollar compensation phase.
