Beyond Domicile: The BHP Litigation and the Functional Interconnection of Public and Private International Law

/0 Comments/in /by

 

from Marcel Vitor de Magalhães e Guerra

 

On 14 November 2025, the English High Court handed down its Stage 1 judgment in Município de Mariana and others v. BHP Group Plc and BHP Group Limited [2025] EWHC 3001 (TCC), finding the defendants liable — under Brazilian law — for the 2015 collapse of the Fundão tailings dam: over 600,000 claimants, an estimated £36 billion, the largest group litigation in English legal history.

Law without Borders? Extraterritorial Regulation and Unilateral Action

/in /by

In an increasingly multipolar world, national and regional actors are reasserting regulatory control over cross-border economic activities. States such as the United States and China, as well as the European Union, are increasingly relying on unilateral measures with extraterritorial reach – particularly in areas such as sanctions, digital regulation, supply chains, competition law, and data protection. At the same time, the multilateral order appears to be under strain: international organizations are being sidelined, agreements are terminated or ignored, and established norms are openly challenged.

To explore the implications of these developments for international (economic) law and the future of global economic cooperation, the German Society of International Law (DGIR) will host a conference in Munich on 11–12 June 2026. Focusing on “Law without Borders? Extraterritorial Regulation and Unilateral Action” the event promises to provide a timely and critical forum for discussing the evolving role of extraterritorial regulation and unilateralism in shaping the international legal order.
