A London court finds BHP liable for the Mariana dam collapse

The High Court ruled that BHP is liable under Brazilian law for the 2015 failure of Samarco’s Fundão dam. The claimants’ lawyers had valued the case at up to £36bn. Damages will be set in later trials, and BHP’s attempts to appeal were refused in 2026.
