The group claim, one of the largest in British legal history, has been brought on behalf of Brazilian individuals, businesses, churches, organisations, municipalities and indigenous people and will open in Manchester on July 22.
BHP spokesman Neil Burrows said the claim did not belong in Britain because it duplicated proceedings in Brazil and the ongoing work of the Renova Foundation, an entity created by the miner and its partners to manage reparations and repairs.
Claimants allege BHP, the world’s largest miner by market value, ignored safety warnings as the dam’s capacity was repeatedly increased by raising its height – and disregarded cracks that pointed to early signs of rupture.
“The public companies at the top of the BHP group structure, which we firmly believe bear ultimate responsibility for the disaster, have until now been insulated from its consequences within the Brazilian legal system,” said Tom Goodhead, a partner at law firm PGMBM, which represents the claimants.
Goodhead said Brazilian environmental law had a long reach and imposed strict liability for environmental damage.
