Mass Tort brief
AI Product Liability, Mariana Dam Carriage, and Baby Powder Trials
English courts and law reformers reshape collective redress, digital strict liability, and corporate catastrophe exposure.
Mass Tort
The High Court keeping Pogust Goodhead in sole control of the £36bn Mariana dam lawsuit stabilizes the world's largest group action ahead of trial.
BackgroundThe 2015 collapse of the Fundão tailings dam in Brazil killed 19 people and devastated river communities, prompting over 420,000 victims to sue BHP in London. Group actions in English courts require designated lead solicitors to manage collective funding arrangements and represent hundreds of thousands of claimants efficiently.
- Mr Justice Waksman rejected an application by a claimant committee and US firm Bailey Glasser to terminate collective fee agreements, preserving stability before preliminary hearings.
- The Court of Appeal confirmed that pre-judgment interest remains recoverable on legal costs even when funded through conditional fee agreements, protecting claimant firms against severe inflation erosion.
- Stage 2 trial proceedings determining causation, individual losses, and corporate liability will run through 2027, making this the largest environmental group litigation in English legal history.

Stripping digital platforms of their software liability shield exposes artificial intelligence vendors to strict statutory damages for algorithmic defects.
BackgroundThe Consumer Protection Act imposes automatic legal liability on manufacturers for injuries caused by defective physical goods. Software, artificial intelligence models, and digital services historically escaped strict liability because English common law treated them as intangible services rather than physical products.
- The proposed reforms expand statutory product definitions to cover downloadable software, artificial intelligence codebases, and digital platform design features, opening developers to direct claims.
- Online marketplaces and fulfilment service providers would face strict compensation liabilities when defective foreign software causes consumer harm, closing a longstanding cross-border legal loophole.
- The consultation introduces rebuttable evidential presumptions to assist claimants injured by opaque algorithms, shifting the burden of technical proof onto technology companies.

Cumulative Horizon redress crossing £600m across all tracks underscores the immense public cost of resolving Britain's most destructive corporate miscarriage of justice.
BackgroundHundreds of subpostmasters were wrongly prosecuted for theft and false accounting after defective Fujitsu Horizon accounting software created fictitious branch shortfalls. The High Court established group litigation liability, forcing the government to fund multi-tier statutory redress programs to compensate victims.
- The Department for Business and Trade recorded £237m delivered under the primary settlement track, covering legal fees and direct financial losses suffered by subpostmasters.
- Parallel statutory schemes disbursed £324m under the Horizon Convictions Redress Scheme alongside £68m for overturned criminal convictions, accelerating compensation delivery for elderly claimants.
- Ministers introduced fixed-sum expedited offers to settle outstanding claims before independent review panels begin formal hearing schedules early next year.
Mass Tort
London's phased baby powder trial opens an active European front against Johnson & Johnson, defeating corporate maneuvers to block talc injury claims.
BackgroundTens of thousands of US consumers filed product liability claims alleging cosmetic talcum powder was contaminated with carcinogenic asbestos fibers. While Johnson & Johnson pursued contentious multi-billion-dollar bankruptcy restructurings in US courts, British victims launched separate claims under English tort law.
- Mrs Justice Hill ordered an initial trial phase on whether talc formulations contained asbestos fibers capable of causing human tumors, narrowing the litigation's core scientific debate.
- The court refused applications by Johnson & Johnson and Kenvue UK to dismiss hundreds of claims over scientific causation, ensuring victims secure access to full evidential disclosure.
- The London litigation establishes substantial European balance-sheet exposure for consumer manufacturers after US bankruptcy maneuvers repeatedly stalled federal multidistrict proceedings.
