# Mariana dam litigation legal representation dispute > Developing situation record from CLSTR: https://clstr.news/situations/mariana-dam-litigation-legal-representation-dispute > Updated: 2026-10-12T14:31:02.000Z. Sources: 4. Developments: 2. The litigation regarding the Mariana dam disaster against mining company BHP has been complicated by internal disputes within the legal representation. Initially, the London-based law firm Pogust Goodhead announced plans to rebrand following a dispute with co-founder Harris Pogust. Mr. Pogust demanded the removal of his surname from the firm and criticized the firm for initiating legal proceedings against the victims' committee, stating, ‘I have never in my 39-year career sued a client.’ Following these developments, the firm rebranded as PGMBM. A legal challenge arose when a 17-member Client Committee attempted to terminate PGMBM’s contract to appoint Bailey Glasser International as the new representative. However, the UK High Court ruled that the Committee lacked the authority to rescind the contract on behalf of all affected parties. The court decision ensures PGMBM will continue representing the Brazilian victims as the litigation moves toward a trial scheduled for April 2027. The ruling also addressed financial risks, noting that rescinding the contracts could expose plaintiffs to approximately £2 billion in costs. ## Timeline ### 2026-10-12: UK High Court maintains PGMBM representation in Mariana dam disaster lawsuit A UK High Court judge ruled that PGMBM will continue representing victims of the Mariana dam disaster, rejecting a Committee's attempt to switch legal counsel to BGI. 2 sources. https://clstr.news/cluster/uk-high-court-maintains-pgmbm-representation-in-mariana-dam-disaster-lawsuit ### 2026-09-24: Pogust Goodhead to rebrand amid dispute over Mariana dam litigation Law firm Pogust Goodhead will rebrand following a dispute with co-founder Harris Pogust over the £36bn Mariana dam litigation and the firm’s decision to take legal action against its own clients. 2 sources. https://clstr.news/cluster/pogust-goodhead-to-rebrand-amid-dispute-over-mariana-dam-litigation --- Cite as: Mariana dam litigation legal representation dispute.
