Parent liability after Mariana v BHP: control, vigilance, and the need for structural reform – Legal Studies
‘On 14 November 2025, the High Court of England and Wales handed down judgment in the largest environmental mass tort in UK history: the group claim by more than 600,000 Brazilian victims of the 2015 collapse of the Fundão tailings dam against the mining giant BHP Group. In Município de Mariana v BHP Group, the Court found BHP (through its UK and Australian-listed parent companies) liable on both strict liability and negligence grounds under Brazilian law.’
