London judges shut down appeal paths in the 1.6-million-motorist emissions suit while UK-listed multinationals resolve multi-billion-pound liabilities.
Mass Tort
GSK paid $2.2bn to wipe out 93% of its Zantac cancer suits — finally lifting a four-year mass-tort discount from its London share price.
BackgroundZantac was recalled in 2020 after US regulators found that its active ingredient could degrade over time into NDMA, a probable human carcinogen. GSK faced tens of thousands of individual personal injury claims in state courts across California, Delaware, and Illinois alleging the heartburn medicine caused various cancers.
- The comprehensive $2.2bn settlement resolves roughly 93% of all pending US state-court heartburn injury claims without any admission of corporate liability.
- Subsequent state court determinations in Delaware dismissed remaining claimant cohorts due to inadequate scientific proof demonstrating ranitidine causes cancer.
- City analysts are watching Wednesday's Q3 financial report to confirm that specialty medicines and vaccine revenues generate enough cash flow to cover the multi-billion legal charge.

London judges refused to pause the £36bn Mariana dam litigation — keeping BHP on track toward history's largest environmental damages determination.
BackgroundThe collapse of the Fundão tailings dam in Mariana, Brazil, killed 19 people, contaminated hundreds of miles of river systems, and devastated local municipalities. Claimant law firms brought group litigation in London because of BHP's historical dual-listed UK corporate headquarters.
- Mr Justice Constable rejected an application to pause proceedings following a representation dispute between claimant legal teams, protecting scheduled quantum hearings.
- The High Court previously established that BHP is strictly liable under Brazilian environmental law for damages stemming from the disaster.
- The proceedings represent the largest environmental mass-tort action ever heard in a British courtroom, testing whether UK courts can hold global parent companies liable for overseas mining disasters.
Mass Tort
The High Court blocked 1.6 million motorists from appealing their emissions defeat — shutting down the bulk of English history's largest mass action.
BackgroundFollowing the 2015 'Dieselgate' scandal, hundreds of thousands of British motorists joined group litigation against car manufacturers alleging illicit defeat devices were installed to pass emissions tests. Lady Justice Cockerill previously ruled that only software explicitly designed to recognize test cycles constituted unlawful defeat devices.
- The High Court held that only three out of 20 sample vehicle models contained prohibited defeat devices under English law, adopting a strict regulatory definition.
- The decision protects automakers including Mercedes-Benz, Stellantis, Renault, Ford, and Nissan from billions of pounds in speculative group compensation liabilities.
- The court will now proceed to scheduled quantum and remedy hearings restricted strictly to the narrow cohort of surviving vehicle models.
Mass Tort
An overturned $60m verdict gave Reckitt critical breathing room — but Abbott's $670m deal means a mass settlement is the only permanent exit.
BackgroundReckitt's Mead Johnson unit faces hundreds of lawsuits alleging cow's-milk-based formula administered to premature infants in neonatal intensive care units significantly increased the risk of necrotizing enterocolitis. Early state jury verdicts awarding massive damages severely weighed on Reckitt's London market valuation.
- The Illinois appellate court overturned the $60m Watson verdict, finding the trial judge improperly admitted prejudicial evidence regarding executive compensation.
- With co-defendant Abbott Laboratories agreeing a $670m settlement resolving ~2,000 cases, Reckitt is evaluating whether to settle remaining federal claims in Chicago.
- City investors are watching Reckitt's legal reserving strategy closely, as an orderly settlement framework would permanently remove a major overhang from its stock.
