English courts press ahead on landmark mass torts and group actions
High Court rulings in London lock in trial dates for historic emissions and mining disputes while the Supreme Court reviews billions in water pollution claims.
Mass Tort
A formal group litigation order imports America's largest toxic tort fight into London — forcing Johnson & Johnson to defend its baby powder safety record before English judges.
BackgroundJohnson & Johnson faces tens of thousands of personal injury lawsuits alleging its baby powder caused cancer through historical asbestos contamination. While the company sought shelter in US bankruptcy courts to halt American claims, English courts allow direct mass tort litigation under consumer safety statutes.
- Mrs Justice Hill scheduled a preliminary trial for early 2028 focused strictly on product contamination and general medical causation.
- The court separated questions of corporate knowledge from the first trial, preventing massive disclosure costs from overwhelming proceedings before causation is proven.
- Spin-off consumer brand Kenvue was named as a co-defendant, carrying potential liabilities inherited during its corporate separation from Johnson & Johnson.
Mass Tort
Mead Johnson's clean jury verdict halts plaintiff momentum in infant formula litigation — removing the existential legal cloud that wiped billions off FTSE giant Reckitt.
BackgroundParents of premature babies filed thousands of toxic tort claims against formula makers, alleging cow's milk products trigger necrotizing enterocolitis, a deadly intestinal infection. Early state court verdicts against Mead Johnson and rival Abbott Laboratories wiped out substantial equity value from Reckitt's balance sheet.
- Federal jurors rejected claims that Enfamil formula was defectively formulated or failed to give adequate hazard warnings to neonatal intensive care physicians.
- The defense verdict leaves Mead Johnson with zero active judgments against it, after an Illinois appeals court threw out an earlier $60 million state verdict.
- City analysts noted the federal jury win gives Reckitt decisive leverage to negotiate global settlement terms without paying catastrophic trial premiums.

Refusing to freeze the Mariana Dam litigation keeps BHP under relentless trial pressure — claimant infighting will not spare the miner a £36 billion reckoning.
BackgroundThe 2015 collapse of the Fundão tailings dam in Brazil killed 19 people and washed 40 million cubic meters of toxic sludge into regional rivers. In late 2025, the English High Court found UK-domiciled BHP entities strictly liable for the disaster in a landmark cross-border tort ruling.
- A committee representing 400,000 Brazilian claimants sought to replace lead solicitors Pogust Goodhead with rival US and UK firms, threatening to derail trial preparation.
- Mr Justice Constable rejected claimant requests to seal the proceedings, ordering that the contest over who controls legal strategy be argued in open court.
- Keeping the April 2027 trial date locked in maintains intense settlement pressure on BHP to resolve the £36 billion cross-border exposure before damages are quantified.
Mass Tort
Forcing the Mercedes test case to trial this month will set emissions compensation formulas — either unlocking billions for 1.6 million drivers or wiping out claimant leverage.
BackgroundThe Pan-NOx group litigation represents the largest consumer product liability action in English history, targeting automakers over alleged diesel defeat devices. The High Court narrowed the technical definition of unlawful software in July, significantly reducing exposure for several vehicle manufacturers.
- Mr Justice Constable stayed parallel quantum trials against Ford and Stellantis, channeling the entire legal fight through the lead Mercedes test case.
- The trial will establish binding formulas for vehicle depreciation, consumer overpayment, and whether distress damages apply under UK consumer protection laws.
- A favorable ruling on valuation models for Mercedes would sharply deflate settlement expectations across 13 other pending group litigation actions.
