English Mass Tort Confronts Capital and Liability Strain
Rival law firms fracture the £36bn Mariana dam litigation, the High Court trims Dieselgate liabilities, and litigation funders face an escalating post-PACCAR squeeze.
Mass Tort
A bitter fee feud over 400,000 claimants threatens to stall Britain's £36bn BHP trial — exposing how mass-tort justice can be held hostage by lawyer infighting.
BackgroundThe 2015 collapse of the Fundão tailings dam in Mariana, Brazil, released toxic mining waste that killed 19 people and devastated the Rio Doce basin. In late 2025, the English High Court found Anglo-Australian mining giant BHP strictly liable under Brazilian environmental statutes.
- A confidential 17-member claimant steering committee voted to replace Pogust Goodhead with BGI, triggering emergency High Court management hearings to decide representation.
- The court must resolve the legal representation standoff before commencing Stage Two quantum trials, stalling the timeline for determining individual compensation sums.
- Litigation funders backing the multi-billion-pound group action are monitoring proceedings closely, with hundreds of millions in contingent legal fees directly at stake.

The High Court's Pan-NOx ruling shields major carmakers from automatic consumer payouts — drawing a strict boundary between regulatory infractions and private compensable harm.
BackgroundThe Dieselgate scandal erupted after car manufacturers deployed software defeat devices that curbed emissions during laboratory tests but shut off during real-world driving. Thirteen consolidated Group Litigation Orders were brought before the London High Court representing roughly 1.6M British vehicle owners.
- Lady Justice Cockerill ruled that unlawful defeat devices must possess an objective sensing purpose, throwing out claims against several manufacturers that lacked targeted cheat software.
- Mercedes-Benz and Stellantis remain liable to proceed to quantum hearings, keeping hundreds of thousands of individual compensation claims active before the courts.
- The judgment sharply confines consumer product liability under English law, preventing claimants from using regulatory breach findings as automatic shortcuts to financial compensation.

J&J's $5.5bn American settlement leaves thousands of British victims out in the cold — locking the company into an unprecedented London product liability trial.
BackgroundJohnson & Johnson faced tens of thousands of North American personal injury lawsuits alleging its cosmetic baby powder was contaminated with carcinogenic asbestos fibers. The healthcare giant discontinued global talc sales in 2023 in favor of cornstarch formulas while continuing to dispute any cancer links.
- Mrs Justice Hill ordered a preliminary issue trial to establish whether talc products sold in Britain between 1965 and 2023 contained detectable asbestos traces.
- The litigation marks the largest pharmaceutical and personal care product liability action ever brought before the English courts, testing corporate accountability across decades.
- Claimant solicitors KP Law confirmed the UK docket is tracking toward a 2028 trial, entirely insulated from American corporate bankruptcy maneuvers or global settlement deals.
Mass Tort
External law firms have extracted £334m defending the Horizon scandal — consuming more taxpayer money on legal advisory fees than victims received in initial compensation.
BackgroundBetween 1999 and 2015, hundreds of sub-postmasters were wrongfully prosecuted for theft and false accounting caused by software bugs in Fujitsu's Horizon accounting system. Alan Bates led 555 branch operators in a landmark High Court group litigation that exposed institutional coverups across senior Post Office management.
- Lead advisory firm Herbert Smith Freehills collected £14.1m over the past 12 months, raising its cumulative fees from the scandal to £202m since 2014.
- The Department for Business and Trade has paid out £223m to approximately 90% of eligible unconvicted postmasters ahead of the December scheme cutoff.
- Sub-postmaster advocates condemned the spending figures, pointing out that public funds paid to commercial lawyers have vastly exceeded initial victim settlements.
