Litigation Funders Vie for Control of BHP Dam Collapse Lawsuit

Two prominent litigation funders are engaged in a significant dispute over control of a substantial legal claim valued at £36 billion (approximately $48.8 billion). This legal battle stems from the catastrophic 2015 collapse of the Samarco iron ore tailings dam in Mariana, Minas Gerais, Brazil, which is considered one of the country's most devastating environmental disasters. The funders are backing rival law firms, each seeking to lead the litigation against BHP Group, the co-owner of the now-defunct Samarco mining company.

The core of the dispute lies in which law firm will represent the thousands of plaintiffs, primarily victims and affected communities, in the ongoing legal proceedings. The litigation is being pursued in both Brazil and the United Kingdom, with the UK proceedings aiming to hold BHP accountable for its role in the disaster. The dam collapse unleashed a torrent of toxic mud and waste, destroying villages, polluting rivers, and causing widespread environmental devastation across hundreds of kilometers, ultimately reaching the Atlantic Ocean. The disaster resulted in at least 19 deaths and displaced thousands of people.

One of the litigation funders, believed to be a significant player in the global legal finance market, is supporting a UK-based law firm that has been actively involved in the proceedings. This firm has been instrumental in building the case against BHP, arguing for substantial compensation for the extensive damages suffered. The opposing funder is backing a different legal team, potentially seeking to streamline the legal process or secure a more favorable outcome for its investment. The involvement of multiple litigation funders highlights the high stakes and complexity of the case, as well as the growing influence of third-party funding in large-scale international litigation.

This clash between funders underscores the strategic importance of controlling major litigation. Litigation finance firms invest capital in legal cases in exchange for a share of any settlement or award. Their involvement can enable plaintiffs who might otherwise lack the resources to pursue complex legal claims. However, it also introduces a commercial dimension, where funders may have differing views on case strategy, settlement offers, and the overall management of the litigation. The outcome of this internal dispute among funders could significantly impact the trajectory and resolution of the £36 billion lawsuit, affecting the compensation received by victims of the dam collapse and the financial liabilities faced by BHP.
