London judges reverse course to reopen $7 bln Brazil dam lawsuit against BHP

London’s Court of Appeal made a U-turn last week by agreeing to reopen a $7 billion lawsuit against Anglo-Australian mining giant BHP, reviving a case over a dam rupture behind Brazil’s worst environmental disaster. PGMBM, who is bringing the claim with the backing of third party funding on behalf of 200,000 claimants, revived the case in April by applying for an oral Court of Appeal hearing – reserved only for exceptional cases – and arguing that the appeal judge had not properly grappled with arguments about why the case should proceed.
