Mass Tort brief
London Courts Test the Reach of Collective Redress
From Pan-NOx appeals and City supply-chain liability to landmark antitrust payouts, English courts are redefining the scope of group litigation.
Mass Tort
Lawyers for 1.6 million drivers are appealing to align English tort law with European precedent — fighting to keep multi-billion-pound emissions claims alive.
BackgroundThe Pan-NOx litigation is the largest consumer group action in English history, accusing major carmakers of using defeat-device software to evade legal emissions limits. In July, the High Court adopted a narrow technical definition of unlawful devices that shielded manufacturers across multiple group orders.
- Claimants argue the High Court diverged sharply from European court rulings, opening a cross-Channel legal rift that lets carmakers sidestep billions in liabilities.
- The appeal outcome will dictate the ground rules for London's upcoming eight-week quantum trial, which calculates financial compensation for drivers.
- Carmakers insist their engine software operated lawfully to protect catalytic exhaust systems from mechanical damage and acute thermal wear.
Mass Tort
Google agreed to pay £260 million to end the UK developer collective action — proving that Britain's opt-out tribunal can extract mega-settlements from Big Tech.
BackgroundApp developers sued Google under UK competition rules, alleging the tech giant abused market dominance by charging 30% Play Store commissions and blocking alternative billing systems. The class action represented thousands of British software businesses seeking recovery for excessive platform fees since 2018.
- The £160 million direct cash payout to developers represents the largest monetary distribution secured in the history of the UK collective proceedings regime.
- The court-sanctioned compromise sidestepped an arduous 10-week liability trial, illustrating that the CAT can force multinational technology firms into commercial settlements.
- The resolution arrives while Whitehall reviews certification rules for collective claims, offering class representatives strong evidence that opt-out mechanisms function effectively.

The High Court will decide whether City standard-setters owe a legal duty to overseas victims — a verdict that could expose London market gatekeepers to supply-chain tort claims.
BackgroundThe LBMA oversees the centuries-old 'Good Delivery' accreditation list that sets the standard for physical bullion traded across London's institutional market. Tanzanian families represented by Leigh Day allege the association breached a common-law duty of care by certifying a refiner linked to mine violence.
- The case tests whether London industry standard-setters can be held liable in English courts for alleged human rights violations committed along overseas supply chains.
- The LBMA argued in court filings that imposing upstream tort liability would make industry accreditation uninsurable and disrupt physical gold settlement in the City.
- A ruling for the claimants would open City accreditation bodies to direct legal exposure for third-party operations across emerging markets.
Mass Tort
The CAT approved £56 million in direct vehicle cartel payouts — setting an automated distribution benchmark that proves collective redress can deliver money to consumers.
BackgroundInternational roll-on/roll-off shipping lines colluded to inflate delivery surcharges on vehicles imported into Britain, prompting an opt-out class action on behalf of buyers. Past UK collective settlements suffered from low consumer engagement, leaving millions in compensation unclaimed.
- Eligible consumers and businesses will receive baseline payouts of £25 per vehicle, using automated registration matching to bypass tedious paperwork.
- CAT Judge Hodge Malek KC endorsed the streamlined distribution framework as a model to prevent class settlement funds from reverting to defendants.
- The tribunal approved £34 million in legal fees and litigation funder returns, providing financial validation for opt-out collective actions under the Consumer Rights Act.
