The English High Court found BHP liable under Brazilian law for the 2015 Fundão dam failure at Samarco, a joint venture between BHP Brasil & Vale. The decision follows a five-month trial examining parent company responsibility for environmental disasters at subsidiary operations. BHP intends to appeal the liability finding while damages assessment awaits future trials scheduled for 2026-2029. Over 610,000 people have already received $6.3 billion compensation through Brazilian mechanisms, including 240,000 UK claimants whose releases the court validated.
