The Supreme Court will decide whether water monopolies can be sued by millions of customers over sewage spills — or remain shielded by industry legislation.
BackgroundRegulated water and sewerage monopolies operate under strict statutory price limits determined by Ofwat alongside binding environmental compliance duties. Consumer advocates are testing competition law to bypass traditional statutory complaint bodies and secure direct consumer restitution.
- The class action accuses six monopoly water companies, including Thames Water and Severn Trent, of systematically underreporting unlawful sewage spills to avoid price penalties.
- The Supreme Court appeal will determine whether section 18 of the Water Industry Act bars consumer class actions from challenging statutory utility operators.
- A victory for claimants would expose the debt-laden British water sector to hundreds of millions in court-ordered customer refunds, worsening already strained balance sheets.

Google's £260 million developer payout is the biggest opt-out settlement in UK history — proving London's competition tribunal can extract massive class action payouts.
BackgroundThe Consumer Rights Act 2015 created an opt-out collective action mechanism before the Competition Appeal Tribunal to enable aggregate antitrust damages. Tech platforms have faced rising legal scrutiny over app store commission rates, which developers challenge as anticompetitive market abuses.
- The historic settlement distributes £160 million in direct compensation to eligible British app developers and allocates £100 million for litigation funding and legal costs.
- The agreement represents both the largest and fastest settlement achieved from initial court filing under the UK's decade-old collective action framework.
- Legal practitioners emphasize that the approved payout establishes an attractive benchmark for ongoing consumer class actions targeting Apple and other Big Tech ecosystems.

Lawyers for 1.6 million UK drivers are fighting to overturn a narrow defeat-device ruling — in a make-or-break appeal for the largest lawsuit in English history.
BackgroundThe Pan-NOx emissions litigation is the largest consumer group action in English legal history, seeking billions in compensation against automotive manufacturers. The High Court previously adopted a narrower test for defeat devices than European judges, shielding carmakers from automatic liability.
- A 2-day permission hearing takes place before the High Court on 7–8 October, directly preceding the scheduled damages trial.
- Claimants argue the trial judge misinterpreted emissions regulations by accepting manufacturer arguments that thermal software windows legitimately protected engines from damage.
- The outcome will determine whether car giants including Mercedes-Benz, Ford, Renault, and Stellantis face billions in aggregate liabilities or walk away largely unscathed.

Scotland's highest civil court has authorized the nation's first talc cancer class action — clearing an independent avenue for UK victims to bring Johnson & Johnson to trial.
BackgroundJohnson & Johnson has faced tens of thousands of personal injury lawsuits in the United States alleging its baby powder contained carcinogenic asbestos fibres. While the company withdrew talc-based powders globally in 2023, victims across Britain are now pursuing collective actions in domestic courts.
- The Scottish proceedings mark the first contaminated talc group action authorized in Scotland, proceeding alongside parallel High Court litigation in England.
- Scots law permits certain surviving family members of deceased victims to bring claims directly within the group action structure, significantly broadening potential recovery.
- Claimants allege the healthcare giant marketed talcum powder for decades despite internal documents indicating raw mineral deposits contained trace asbestos.
