The seabed disputes chamber of the international tribunal for the law of the sea gave its first advisory opinion on 1 february 2011. Asked to specify the obligations of states sponsoring persons and entities authorized to explore and exploit the Area’s resources, pursuant to the united nations convention on the law of the sea, and to clarify the circumstances in which the responsibility of those states might be implicated, the chamber provides valuable enlightenment not only as to the law of the sea, but also environment law and the law of international responsibility. The opinion allows the chamber, at the end of a balanced approach between caution and resolve, to pave the way for its own judicial policy.
