Mass Tort brief
London Courts Tighten Grip on Multinationals
Record opt-out payouts and expanding parent liability trials cement London as a premier venue for global mass tort claims.
Mass Tort
London's competition tribunal has sanctioned its largest collective settlement — demonstrating Britain's opt-out class action system can extract hundreds of millions from dominant tech platforms.
BackgroundThe Consumer Rights Act 2015 created an opt-out collective proceedings mechanism in London allowing representative claimants to sue corporations for competition breaches on behalf of affected classes. Professor Barry Rodger brought the action alleging Google abused its dominant position by imposing excessive 30% commissions on digital app transactions.
- The approved order establishes a £160 million direct compensation distribution fund for British app developers who paid Play Store commissions since August 2018.
- The resolution represents the largest collective settlement payout sanctioned by the Tribunal, demonstrating the commercial viability of the UK's opt-out collective regime.
- Legal practitioners note that the settlement precedent will directly inform procedural strategies for parallel multi-billion-pound collective claims pending against Apple and Amazon.
Mass Tort
The High Court has rejected BHP's attempt to halt the £36bn Mariana Dam trial — keeping the largest mass tort in British history on track for judgment.
BackgroundThe 2015 Fundão tailings dam failure released 40 million cubic meters of toxic mining waste across Minas Gerais, destroying settlements and killing 19 people. English appellate courts affirmed jurisdiction over Anglo-Australian miner BHP, allowing victims to litigate parent liability under Brazilian law in London.
- The court scheduled an urgent two-day hearing in October to resolve an acrimonious leadership struggle between claimant firms Pogust Goodhead and Bailey Glasser.
- BHP argued that parallel compensation negotiations with Brazilian federal authorities justified staying the London action, but judges ruled English proceedings must continue.
- The £36 billion exposure represents the largest mass tort claim ever heard in a British court, creating persistent liability overhang for FTSE 100 investors.
Mass Tort
The High Court has whittled Britain's 1.6-million-driver emissions lawsuit down to Mercedes and Stellantis — clearing a direct path to an overdue quantum damages trial.
BackgroundFollowing the 2015 emissions scandal, claimant firms secured 13 Group Litigation Orders seeking compensation for British motorists whose vehicles contained defeat devices. High Court judges recently issued liability guidance establishing strict criteria for what vehicle software controls breached European and domestic emissions rules.
- The High Court's narrow interpretation of illegal defeat devices led to the dismissal of core liability claims against Ford, Renault, and Nissan.
- Mercedes-Benz was designated as the primary defendant for a lead damages assessment trial scheduled to calculate compensation benchmarks per affected vehicle owner.
- Claimant steering groups are seeking permission to appeal secondary manufacturer dismissals, threatening to prolong overall case timelines across the next two years.
Mass Tort
English judges are refusing to pause British talc cancer claims — leaving Johnson & Johnson exposed to consumer product liability trials outside US bankruptcy jurisdiction.
BackgroundConsumers worldwide have brought personal injury lawsuits alleging asbestos-contaminated cosmetic talc caused terminal ovarian cancer and mesothelioma. While Johnson & Johnson negotiated a $5.5 billion settlement inside US Chapter 11 bankruptcy proceedings, British victims formed a Group Litigation Order in London.
- Mrs Justice Hill directed the preliminary separation of general scientific causation issues from individual damages assessments to accelerate substantive pre-trial hearings.
- The UK action, managed by KP Law, represents cancer sufferers seeking compensatory damages under the strict statutory provisions of the Consumer Protection Act 1987.
- The procedural timetable insulates British claimants from US bankruptcy court automatic stays, maintaining multi-billion-pound international balance sheet exposure for Johnson & Johnson.
