The Regime of Islands Reframed

Abstract

The definition of islands represents a longstanding source of uncertainty under the international law of the sea, resulting in numerous disputes among coastal States. This is primarily due to the significant impacts the legal status of islands has on both their maritime entitlements and potential role in the delimitation of maritime boundaries. This study highlights the geographical diversity of islands and outlines the historical development of as well as progress towards the clarification of the legal definition of islands. The Award of the Arbitral Tribunal in the South China Sea case is examined in detail as it provides the first detailed international judicial examination and interpretation of the Regime of Islands. The definition of other types of insular features including low-tide elevations and artificial islands as well as submerged features are also addressed. Reactions to the interpretation of Article 121 by the Tribunal in the South China Sea case are explored before conclusions and considerations on the potential implications of these developments are offered.
