High Court Holds Trial Dates on Mariana Dam and Diesel Claims
English judges refuse stays in multi-billion-pound group actions, while Law Commission proposals could expand opt-out litigation.
Mass Tort
The High Court refused to let a bitter funder feud stall Britain's biggest mass tort — keeping BHP facing a catastrophic £36B reckoning.
BackgroundThe 2015 Fundão dam collapse in Brazil unleashed 43M cubic metres of toxic waste, killing 19 people and devastating the Doce River basin. London judges previously found BHP strictly liable, leaving more than 420,000 victims waiting for English courts to calculate compensation.
- Former Pogust Goodhead chief executive Thomas Goodhead joined rival firm Bailey Glasser, siding with claimant committee members attempting to replace lead legal counsel.
- The bitter leadership dispute pits litigation funders Gramercy and North Wall Capital against each other following disagreements over a proposed $1.4B settlement offer.
- The High Court scheduled an open hearing in October 2026 to resolve representation rights without pushing back the main trial on monetary compensation.

The High Court locked carmakers into an October damages trial — finally determining what 1.6M British drivers can collect over diesel emissions tampering.
BackgroundThe pan-NOx litigation brings together 13 Group Litigation Orders against carmakers including Mercedes-Benz, Ford, and Stellantis over diesel emissions tampering. Earlier rulings narrowed the technical definition of unlawful defeat devices, curtailing some claims while confirming buyers retain private law damages rights.
- Mr Justice Constable rejected an application by carmakers to stay proceedings, keeping the initial lead quantum trial on schedule for 26 October.
- The trial will evaluate actual vehicle valuation loss across selected test models to establish binding payout benchmarks for the remaining 1.6M claimants.
- Carmaker defense solicitors argued earlier liability restrictions will severely constrain final awards compared to the billions initially sought by claimant law firms.

English judges establishing trial timetables for talc claims ensures Johnson & Johnson cannot sidestep British product-liability scrutiny through US corporate restructuring.
BackgroundMore than 3,000 UK claimants allege their ovarian cancer and mesothelioma were caused by asbestos contamination in baby powder used over decades. In the US, Johnson & Johnson has repeatedly used bankruptcy filings and multi-billion-dollar offers to manage tens of thousands of similar lawsuits.
- High Court judges reviewed defense strike-out bids and ordered standardized disclosure across decades of historical laboratory testing archives.
- The court set sequential hearings to test general product liability and medical causation before opening individual compensation assessments for claimants.
- Claimant solicitors at KP Law warned that corporate spinoffs between J&J and Kenvue will not insulate either entity from UK common-law liabilities.
Mass Tort
Mead Johnson's clean defense verdict removes outstanding US jury penalties against Reckitt — dismantling a multi-billion-pound liability threat that haunted London investors.
BackgroundMead Johnson and Abbott Laboratories face hundreds of lawsuits alleging cow's-milk preterm infant formula causes necrotizing enterocolitis, a severe gastrointestinal illness. London-listed Reckitt previously suffered severe share price drops following early adverse state court jury verdicts that awarded tens of millions.
- An Illinois federal jury deliberated five hours before rejecting claims that Enfamil Premature formula had design defects or failed to give adequate medical warnings.
- The complete defense verdict follows an Illinois state appeals court overturning a prior $60M award against Mead Johnson, wiping clean its outstanding jury liabilities.
- City equity analysts noted the defense victory sharply reduces expected litigation settlement provisions, restoring confidence across London trading desks in Reckitt's core valuation.
