 More than 200,000 Brazilian people and groups will next week kick off a 5 billion-pound 6.3 billion lawsuit against Anglo-Australian miner BHP in Britain over a 2015 dam failure that led to Brazils worst environmental disaster. An initial, eight-day hearing will establish whether the case can be heard in Britain, although the judge is expected to reserve judgment until later in the year. 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.
