Bailey Glasser International Replaces Pogust Goodhead on the Mariana Dam Litigation
Bailey Glasser International has taken over conduct of the multi-billion pound group claim against BHP arising from the 2015 collapse of the Fundão Dam in Mariana, Brazil, replacing Pogust Goodhead as solicitors for the claimants.
According to a press release from Bailey Glasser International, the firm was appointed in *Município de Mariana and others v BHP Group (UK) Ltd and another* following a decision of the Client Committee dated 28 August 2026, with Hausfeld & Co LLP supporting the conduct of the litigation in London. The vote to terminate Pogust Goodhead's retainer and appoint BGI was unanimous among the Committee's members.
The release states that the decision followed "confidential matters identified by the Client Committee about Pogust Goodhead's conduct of the case," which were "repeatedly communicated to Pogust Goodhead, including by way of a formal notice."
The claim is one of the largest group actions in English legal history, brought for more than 420,000 Brazilian claimants. Liability was established at the Stage One trial, and after the Court of Appeal refused BHP permission to appeal in May 2026 it can no longer be challenged. The Stage Two trial on causation and quantum is listed from April 2027 to March 2028.
Faranak Ghajavand, Partner and Head of Commercial Disputes at BGI, said the firm's priority is "continuity for the claimants, with the case proceeding without disruption," adding that senior members of the existing counsel team will return to the matter.
The terms of the claimants' representation are unchanged, with fees payable only if the case succeeds. BGI is the first international venture of US firm Bailey & Glasser LLP, and is a trading name of Edward McCourt & Company LLP.
