BHP Group must stop funding legal action seeking to halt some Brazilian municipalities from bringing a multi-billion pound claim over one of Brazil's worst environmental disasters, London's High Court ruled on Tuesday.
More than 720 000 Brazilians, including around 50 municipalities, are suing BHP over the 2015 collapse of the Mariana dam, which was owned and operated by its Samarco joint venture with Brazilian iron-ore miner Vale.
