What Would Happen When There Is No More Earth? Legal Fictions, Maritime Entitlements, and the Double Standard of International Law

Main Article Content

José María OLVERA AMADO

Abstract

Abstract. Sea-level rise is one of the major global challenges of our time. Its effects are not only geographical but also directly impact international law. One of the most significant consequences involves State territory and maritime entitlements, as baselines shift due to rising sea levels. This context has sparked debate over whether to adopt fixed or ambulatory models for baselines. However, this debate remains inconclusive, with many questions unresolved and few definitive answers. This article aims to update the current state of this debate and offer a critical perspective on legal fictions that have sometimes benefited powerful States but not others. It examines whether international law continues to uphold principles of equity or remains influenced by major powers, especially considering the doctrines of Empire by Purchase and Lebensraum.
