Funding Disputes and Collective Actions Remake UK Litigation
Major funding reforms and landmark group litigation orders reshape the legal battlefield for homebuilders, pharmaceutical giants, and class-action funders.
Mass Tort
The High Court's group litigation order against Johnson & Johnson clears a coordinated path for thousands of cancer victims — potentially forcing J&J into a major UK-specific settlement.
BackgroundGroup Litigation Orders (GLOs) allow individual lawsuits sharing common factual or legal issues to be managed collectively in the High Court of Justice. This procedural framework serves as the primary UK alternative to US-style class actions for personal injury and negligence claims.
- Over 2,100 initial claimants allege that J&J's asbestos-contaminated cosmetic talc caused mesothelioma or ovarian cancer, with up to 5,000 more expected to register before the court-mandated cutoff date.
- The claimants allege J&J knowingly suppressed reports of raw supply contamination for decades, potentially forcing the pharmaceutical giant to settle rather than risk a highly public High Court trial.
- The court permitted claimants to introduce new allegations regarding carcinogenic iron contaminants, introducing a distinct legal avenue that complicates J&J's defense strategy.
Mass Tort
A landmark £4.5B opt-out class action targets major UK home developers — certifying this class would expose the entire construction sector to unprecedented, industry-wide collusion damages.
BackgroundOpt-out collective actions allow a class representative to sue on behalf of a large group of affected consumers without requiring individuals to actively join. The Competition Appeal Tribunal has exclusive jurisdiction to hear these claims, which have historically focused on antitrust and competition law.
- Backed by £29 million in third-party litigation funding from Burford Capital, the lawsuit represents over 700,000 UK new-build homebuyers, marking a dramatic escalation in funded consumer actions.
- The claim targets major builders including Persimmon, Taylor Wimpey, and Barratt Redrow, alleging consumers overpaid by up to £6,200 per home and potentially driving down their shares if damages are awarded.
- This case represents the largest property litigation in UK history, testing whether the tribunal will certify massive consumer classes without prior formal regulatory infringement findings by the competition watchdog.
Mass Tort
The government's targeted class-action funding reform expands contingency fees for competition claims — but keeps the door firmly shut against US-style mass consumer personal injury lawsuits.
BackgroundThird-party litigation funding allows specialized firms to cover the legal costs of a lawsuit in exchange for a percentage of any eventual payout. The UK government has historically restricted these arrangements in general consumer claims to prevent the rise of a highly litigious culture.
- The government explicitly decided not to expand the opt-out collective actions framework to general consumer or injury claims, shielding manufacturers and healthcare providers from US-style class-action exposure.
- For competition cases, the reforms lift the ban on damages-based agreements, enabling contingency fee funding modeled after successful Australian frameworks that have attracted billions in private capital.
- The rules tighten initial certification thresholds for class representatives, making it harder for professional litigators to launch speculative actions without clear evidence of systemic market harm.
