Challenging the Notion of a “Single Continental Shelf”

Abstract

According to international courts and tribunals, there exists in law only a “single continental shelf,” rather than an “inner” and an “outer” continental shelf. What originally started as a simple phrase to justify the jurisdiction of the court or tribunal eventually ended up as a justification for using the traditional delimitation methodology for delimitation of the continental shelf beyond 200 NM. This article challenges the notion of a “single continental shelf” on various bases, namely, with respect to bases of entitlement, delineation formulas, the nature of coastal state rights, and the inapplicability of the equidistance line beyond 200 NM.
