Mass Tort

The High Court's narrow emissions ruling has gutted the UK's largest-ever group litigation — sparing major carmakers billions in potential damages.

BackgroundThe Diesel Pan-NOx litigation represents 1.6 million UK vehicle owners alleging that car companies used illegal software to manipulate emissions tests. Group litigation orders allow thousands of individual claims to be managed as a single case.

Points
  1. The High Court ruled that Ford, Renault, and Nissan sample vehicles did not contain prohibited defeat devices, sparing them from billions in potential damages.
  2. Adverse findings were issued against Mercedes-Benz and Peugeot-Citroën over specific software, setting up a second trial in October 2026 to assess damages.
  3. Claimant law firms are planning appeals, arguing the UK ruling departs from established EU precedent and creates a legal divergence that harms consumers.

Mass Tort

The upcoming case management hearing will decide the scientific evidence thresholds J&J must face — defining the legal risk in Britain's largest talc suit.

BackgroundJohnson & Johnson faces tens of thousands of lawsuits globally over its legacy baby powder product, which it transitioned to cornstarch in 2023. This UK litigation represents one of the largest product liability actions in British legal history.

Points
  1. The High Court appointed KP Law as Lead Solicitors and ordered detailed claimant schedules, which will be used to select representative lead cases for initial trials.
  2. Johnson & Johnson is expected to press for strict scientific causation thresholds, attempting to narrow its legal exposure by excluding claims without robust medical links.
  3. The formal registration cut-off date for new UK claimants was established as March 22, 2027, giving plaintiff law firms a clear timeline to register outstanding victims.

Mass Tort

The High Court's refusal to delay the ABF Malawi trial signals a growing willingness by English judges to hold UK parent firms liable for overseas ESG disasters.

BackgroundMalawian residents claim ABF's sugar subsidiary built protective earthen embankments that diverted devastating floodwaters into their village during a 2022 tropical storm. English courts have increasingly allowed ESG class actions against UK parent firms for foreign subsidiary operations.

Points
  1. The High Court rejected ABF's proposal to delay proceedings by holding a separate preliminary issues hearing in 2030, significantly speeding up the path to a full compensation trial.
  2. The multi-million-pound lawsuit represents a high-profile example of English courts asserting jurisdictional oversight over the overseas environmental impacts and ESG compliance of London-listed parent multinationals.
  3. Claimants allege that the two-meter-high flood embankments built by ABF's subsidiary directly caused seven deaths, leaving hundreds of villagers homeless following Tropical Storm Ana.
