English High Court Finds BHP Mining Liable for 2015 Dam Collapse

The English High Court has ruled that BHP Mining, an Australian company, is liable for the catastrophic collapse of the Fundão Dam in Brazil, which occurred in 2015. This tragic event resulted in the deaths of 19 people and is regarded as one of the most significant environmental disasters in Brazilian history. Despite not owning the dam at the time, the court’s decision highlights the company’s responsibility under Brazilian environmental law.

In a ruling delivered on October 13, 2023, Justice Finola O’Farrell concluded that the failure of the dam was reasonably foreseeable. She dismissed BHP’s defense argument that the incident was sudden and unexpected. Evidence presented in court indicated that more than a year prior to the collapse, the dam exhibited distress signals, including seepage and cracking. A proper stability analysis could have identified a significantly elevated risk of failure.

Application of Brazilian Law in English Court

This landmark decision is notable for its application of Brazilian environmental law within an English court context. BHP had previously challenged the case’s validity, claiming it duplicated Brazilian legal proceedings and constituted an “abuse of process.” However, the court overcame these objections, allowing the case to proceed.

Justice O’Farrell clarified that BHP falls under the definition of a “polluter” as stipulated by Brazilian law. According to Article 3, IV of the Brazilian Environmental Law, the strict liability regime holds parties responsible for environmental damage regardless of fault. The court adopted a broad, multifactorial test from Brazilian jurisprudence, indicating that liability extends beyond direct operators to include those who finance or benefit from such operations.

The ruling referenced guidelines from the Superior Court of Justice in Brazil, emphasizing that responsibility includes factors such as control over the activity, risk creation, and economic benefit derived from the operations. This comprehensive approach could set a powerful precedent, enabling accountability for multinational corporations operating in foreign jurisdictions.

Impact of the Dam Collapse on Brazil’s Environment

The Fundão Dam’s failure led to an environmental catastrophe, with an estimated volume of mine waste comparable to filling 13,000 Olympic-size swimming pools. The toxic sludge flowed into the Doce River, causing extensive ecological damage. A report by the Wilson Center detailed the devastating effects on biodiversity, noting that around 29,000 fish carcasses were collected, severely disrupting the food chain. Many birds faced starvation as their primary food sources were decimated.

The socio-environmental damage caused by the disaster has been estimated between 37.6 billion to 60.6 billion reais. The destruction of approximately 80 percent of native vegetation further exacerbated the ecological crisis, leading to long-term consequences for the region’s ecosystem.

Before this pivotal ruling, various legal actions had been initiated against top BHP executives, who faced charges of homicide related to the deaths of 21 individuals. These proceedings were later suspended, but the latest ruling may reignite scrutiny of BHP’s operations and decision-making processes.

As the global community grapples with the implications of corporate responsibility for environmental disasters, the English High Court’s decision serves as a significant reminder of the need for accountability in multinational operations.
