On Friday, the International Tribunal for the Law of the Sea in Hamburg dismissed an attempt by two subsidiaries of The Metals Company to halt a United Nations investigation into alleged breaches of deep-sea mining contracts. The legal challenge centered on exploratory permits in the Clarion-Clipperton Zone, an area of the Pacific Ocean regulated by the International Seabed Authority (ISA) and home to significant cobalt and nickel reserves.
The case follows The Metals Company’s application for US-sponsored mining permits earlier this summer, which triggered scrutiny from the ISA over compliance with environmental and operational requirements. With global demand for critical minerals climbing—cobalt prices reached $29,000 per tonne this week—scrutiny of deep-sea mining operations has intensified, especially during peak summer shipping seasons when maritime activity is most visible.
The Tribunal’s decision means the UN probe, originally launched in June, will proceed without delay. It also refocuses attention on the ISA’s 2026 target to finalize binding international regulations for seabed mining. While industry groups argue that deep-sea extraction is essential for the energy transition, NGOs including the Deep Ocean Stewardship Initiative have warned of possible irreversible damage to marine ecosystems if oversight is lax.
In Saturday’s court statement, Judge Tomoko Okamoto emphasized the need for transparent governance, citing the Tribunal’s mandate to uphold the UN Convention on the Law of the Sea. The Metals Company expressed disappointment, but signaled it would cooperate with investigators.
With the summer tourist season bringing new eyes to coastal communities from California to Kiribati, calls for moratoria on commercial seabed mining have gained volume. The next ISA council session, set for later this month in Kingston, Jamaica, is expected to review interim findings from the ongoing inquiry.
