Mass Tort brief
English Courts Redraw Mass Liability
From algorithmic strict liability to £36bn environmental trials and sewage class actions, London courts are expanding corporate liability across digital and industrial sectors.
Mass Tort
Expanding strict liability to software strips tech developers of traditional legal shields — opening algorithms to direct consumer injury suits.
BackgroundUnder the Consumer Protection Act 1987, strict liability applies almost exclusively to physical manufacturing defects that cause tangible bodily harm. Software, neural networks, and digital platforms have historically escaped statutory product liability because English courts treat code as intangible advice or services.
- The proposals expand the statutory definition of a product to encompass algorithmic systems, standalone software files, and platform engagement mechanics like infinite scrolling.
- Claimants would no longer have to reverse-engineer opaque deep-learning models to prove developer negligence in complex systemic product failures.
- The consultation also considers broadening statutory defendants to online marketplaces and abolishing the 10-year limitation longstop for latent algorithmic defects.
- Tech lobby groups warned that imposing strict liability on software will trigger defensive coding practices and inflate insurance premiums for British startups.
Mass Tort
The High Court blocked a leadership challenge in the £36bn Mariana Dam action — keeping lead solicitors in place for massive 2027 damages trials against BHP.
BackgroundThe 2015 Fundão dam collapse in Minas Gerais unleashed millions of cubic metres of toxic mining waste, levelling villages and killing 19 people. Over 400,000 Brazilian claimants joined group litigation in London, asserting BHP shares legal parent-company liability for the disaster.
- The court held that a dissident client committee lacked legal authority to terminate collective conditional fee agreements and High Court management orders.
- The decision solidifies Pogust Goodhead's unbroken control over the largest and most expensive group litigation in English legal history.
- The High Court previously established BHP's strict liability as an environmental polluter, with the Court of Appeal refusing permission to appeal.
- Stage 2 quantum trials are scheduled in London across 2027 and 2028, testing individual damages claims across hundreds of thousands of claimants.
Mass Tort
UK courts are advancing asbestos talc claims independently of US settlements — exposing Johnson & Johnson and Kenvue to £1bn in British liabilities.
BackgroundJohnson & Johnson faces tens of thousands of personal injury lawsuits worldwide alleging that historical cosmetic talc products contained carcinogenic asbestos fibres. While the company spun out its consumer brands into Kenvue and pursued US bankruptcy settlements, English claims operate under domestic civil liability rules.
- The High Court ordered a split trial, determining that asbestos contamination and epidemiological causation must be settled before corporate knowledge is tested.
- Claimant solicitors KP Law confirmed British actions are insulated from US bankruptcy stays or proposed transatlantic global settlement structures.
- The London litigation exposes corporate spinoff Kenvue UK and commercial casualty insurers to potential compensation payouts exceeding £1 billion.
- Cross-examination will focus on historical analytical testing records for cosmetic talc batches distributed across the UK between 1965 and 2023.
Mass Tort
The Supreme Court will decide whether water monopolies can use industry statutes to block a £1.5bn consumer class action over hidden sewage spills.
BackgroundThe Consumer Rights Act 2015 created an opt-out collective proceedings regime in the Competition Appeal Tribunal to penalise corporate competition abuses. Water utilities argue that the Water Industry Act 1991 assigns exclusive regulatory oversight to industry watchdogs, barring private civil damages claims.
- The litigation targets six regional monopolies: Thames Water, Severn Trent Water, United Utilities, Anglian, Yorkshire, and Northumbrian Water.
- The Supreme Court appeal will determine whether statutory water industry regimes completely preclude tribunal class actions against regulated monopolies.
- Certification would allow the claim to proceed on behalf of millions of household bill-payers in only the third opt-out case to reach the Supreme Court.
- Severn Trent and United Utilities warned that adverse judgments could expose the broader privatised utility model to coordinated multi-billion-pound collective liabilities.
