The relationship between the continental shelf regime and a new international instrument for protecting marine biodiversity in areas beyond national jurisdiction

States have acknowledged that the new internationally legally binding instrument (ILBI) for the conservation and sustainable use of marine biodiversity beyond national jurisdiction must take account of the interests of coastal states with continental shelves that extend beyond 200 nautical miles. This article argues that the ILBI should go beyond repeating the existing legal position as set out in international treaties and customary international law. In particular, the concept of sedentary species is unhelpful in the context of a legal regime governing the use of marine genetic resources. The article makes a number of suggestions for possible inclusions in the ILBI to clarify the relationship between the continental shelf regime and the regime for biodiversity beyond national jurisdiction.
