Appellate rulings on BHP's Mariana dam and automotive emissions anchor an expanding slate of UK group actions.
Mass Tort
A formal High Court Group Litigation Order clears the way for British talc cancer trials — exposing Johnson & Johnson to major UK liability damages.
BackgroundJohnson & Johnson faces tens of thousands of personal injury lawsuits globally alleging its legacy cosmetic talc products contained trace asbestos contamination. While the healthcare conglomerate pursued bankruptcy settlements in the US, British claimants must litigate through English civil courts.
- The High Court order establishes a centralised register for thousands of British claimants to join collective proceedings against the healthcare giant, standardising procedural management.
- A parallel group action has been registered in the Scottish Court of Session, testing compensation principles under Scots damages law without English cost-capping rules.
- Johnson & Johnson continues to deny allegations of asbestos contamination, asserting that decades of independent testing confirm the safety of its talc and disputing scientific causation links.

By upholding costs in the £36bn Mariana dam suit, the Court of Appeal kept BHP on the hook — clearing the way to calculate historic environmental damages in London.
BackgroundThe 2015 collapse of the Fundão tailings dam in Minas Gerais, Brazil, released toxic mining sludge that killed 19 people and devastated hundreds of miles of river basin. More than 450,000 Brazilian individuals and municipalities brought suit in London against Anglo-Australian miner BHP as parent company.
- Appellate judges dismissed BHP's challenge against pre-judgment interest awarded to claimants funded via conditional fee agreements, protecting early legal cost recovery.
- The decision follows the High Court's Stage 1 liability verdict that designated BHP strictly liable as an environmental polluter under Brazilian law, narrowing parent-company defence options.
- City litigation funders noted the judgment affirms London's jurisdiction as an enforceable venue for multi-billion-pound corporate cross-border tort actions, encouraging further international filings.

Lawyers representing 1.6m British motorists are escalating Dieselgate to the Court of Appeal — fighting to hold automakers liable for emissions defeat software.
BackgroundThe UK Pan-NOx litigation represents the largest consumer group action in English legal history, targeting manufacturers including Mercedes-Benz, Ford, and Stellantis. Plaintiffs argue that engine management systems deliberately manipulated nitrogen oxide emissions controls during statutory laboratory testing.
- Steering firms Leigh Day and Hausfeld are lodging appellate filings to challenge High Court findings regarding technical regulatory compliance, seeking to revive broader software deception claims.
- A parallel quantum trial against Mercedes-Benz will proceed in the High Court to establish financial compensation formulas for affected vehicle owners, testing statutory loss calculations.
- Automotive manufacturers face potential cumulative UK liabilities stretching into hundreds of millions of pounds if appellate judges revive broader claims, adding further pressure to diesel residual values.

Over 840 infant formula injury suits continue to hang over Reckitt Benckiser — keeping the FTSE consumer giant's shares under persistent legal pressure.
BackgroundFTSE 100 consumer products giant Reckitt acquired baby formula manufacturer Mead Johnson in 2017 for $16.6bn to expand in global infant nutrition. However, a wave of US lawsuits alleging formula caused fatal bowel disease in premature infants has weighed heavily on Reckitt's market valuation.
- An Illinois appellate court overturned a prior $60m jury verdict against Mead Johnson on learned intermediary grounds, giving Reckitt temporary legal breathing room and establishing key precedent.
- Federal MDL Judge Rebecca Pallmeyer has scheduled upcoming bellwether trials to test causation evidence across hundreds of remaining infant claims, shaping future settlement leverage.
- City equity analysts estimate potential legal settlements could reach hundreds of millions of dollars, constraining capital expenditure across the group and delaying planned corporate reorganisations.
