[1/3] Members of the Krenak indigenous people, Daniel Krenak, Andreia Krenak, Djanira Krenak, Maycon Krenak and Marcelo Krenak, demonstrate outside the High Court in London, Britain December 13, 2022.
BHP (BHP.AX) was initially sued by around 200,000 Brazilians over the 2015 collapse of the Fundao dam, owned by the Samarco joint venture between BHP and Brazilian iron ore mining company Vale (VALE3.SA).
BHP, the world's biggest miner by market value, denies liability and in December applied to join Vale to the case.
BHP has said the London lawsuit duplicates legal proceedings and reparation and repair programmes in Brazil.
BHP has applied to the Supreme Court to overturn that decision and its application is pending.
