The High Court blocked an internal bid to oust Pogust Goodhead — keeping the firm in charge of the £36B trial against BHP.
BackgroundThe 2015 Fundão dam collapse in Brazil unleashed toxic mining tailings that killed 19 people and contaminated the Rio Doce river basin. After London courts established BHP's strict liability under Brazilian law, quantum proceedings were scheduled to calculate individual losses.
- Pogust Goodhead warned that transferring case files to rival firm Bailey Glasser would derail quantum preparations and expose 420,000 claimants to £2bn in adverse costs.
- Mr Justice Waksman ruled individual client retainers could not be revoked by a breakaway claimant committee, maintaining existing governance over the group litigation order.
- The decision protects lead counsel standing in the largest group action in English legal history ahead of formal quantum hearings set for April 2027.
- BHP continues to dispute total exposure, arguing parallel compensation funds distributed in Brazil should offset any future damages awarded in London.

The High Court ordered rugby concussion claimants to pay £1.5M in adverse costs — delivering a sharp blow to funders backing the lawsuit.
BackgroundRoughly 1,000 former professional and amateur rugby union and league players are suing governing bodies, alleging negligent head injury protocols caused early-onset dementia. Group litigation orders demand strict adherence to procedural deadlines to manage high volumes of medical disclosure across hundreds of individual claims.
- Senior Master Cook and High Court judges penalised claimants for chronic delays in producing verified medical reports and CPR-compliant loss schedules.
- Governing bodies World Rugby, the Rugby Football Union, and the Welsh Rugby Union sought £2.8M in indemnity costs, citing serious trial preparation prejudice.
- The £1.5M penalty must be satisfied within 14 days, placing acute cash-flow demands on third-party commercial funders underwriting the concussion action.
- Sports authorities across football, cricket, and cycling are monitoring the proceedings as emerging brain injury claims gather momentum across British sports.
Mass Tort
The Law Commission proposed extending strict liability to artificial intelligence — ending a 40-year statutory shield for defective code.
BackgroundThe Consumer Protection Act 1987 holds manufacturers strictly liable for physical injuries caused by defective goods, but historically excluded digital software from its scope. As autonomous systems take control of physical machinery, injured UK consumers currently face the difficult burden of proving corporate negligence.
- The proposed reforms expand statutory product definitions to cover standalone software, machine learning algorithms, and digital files used in 3D manufacturing.
- To assist claimants facing complex digital supply chains, the commission proposes rebuttable legal presumptions regarding defect status and causation.
- The formal public consultation runs until 14 January 2027, harmonising English tort law with the European Union's updated Product Liability Directive.
- Insurers cautioned that imposing strict liability on software developers could sharply increase product liability insurance premiums across Britain's domestic technology sector.

Funder LCM entered run-off following heavy portfolio losses — deepening a capital squeeze across the UK mass litigation market.
BackgroundThird-party litigation funders cover legal fees for claimants in complex group actions in return for a share of final damages or settlement proceeds. The UK Supreme Court's 2023 PACCAR ruling created legal uncertainty around litigation funding agreements by classifying percentage-based recovery terms as damages-based agreements.
- LCM halted all fresh investment commitments after 7 of its 8 recently resolved commercial litigation bets resulted in severe financial losses.
- The firm's managed exit follows the collapses of UK funders Fenchurch Legal and Woodville Consultants, tightening liquidity across London group actions.
- Commercial litigation boutiques warned that retrenching capital providers will restrict claimant access to justice for expensive, document-heavy British class actions.
- City law firms are redrafting existing funding agreements to withstand judicial challenges and protect claimants against rising adverse costs liabilities.
