Developing a Business and Human Rights Treaty: Lessons from the Deep Seabed Mining Regime Under the United Nations Convention on the Law of the Sea

This article delves into the deep seabed mining regime under the United Nations Convention on the Law of the Sea (UNCLOS) with a view to inform the negotiating process of the proposed business and human rights (BHR) treaty. It highlights points of convergence and divergence between the two regulatory regimes and explores how the BHR treaty negotiations could draw from the deep seabed mining regime with regard to the responsibility and liability of states and corporations. In particular, it suggests that a BHR treaty could incorporate some of the arrangements of UNCLOS to address state obligations and direct corporate human rights obligations, both of a general and specific nature, including the obligation to carry out human rights due diligence. The article also proposes a mechanism of responsibility and liability of states and corporations under the future BHR treaty going beyond UNCLOS and embracing residual liability for home and/or host states.
