Baselines under the International Law of the Sea

Between 2008–2018 the International Law Association (ILA) Committee on Baselines under the International Law of the Sea produced two reports on the normal baseline (2012) and straight and archipelagic baselines (2018). The Sofia Report (2012) is organised around the interpretation of Article 5 of the 1982 United Nations Convention on the Law of the Sea (LOSC) concerning the normal baseline. Under the leadership of Committee Chair Judge Dolliver Nelson, the Committee was asked to identify the existing law on the normal baseline and to assess the need for further clarification or development of that law in light of substantial coastal change. The Report applies the rules of treaty interpretation, including an assessment of the ordinary meaning of the terms of the treaty and, because those leave the meaning ambiguous, the preparatory works of the normal baseline provision. The Report then turns to address the application of the existing law to changing coasts and concludes that the law on the normal baseline is inadequate to address problems of substantial territorial loss. The Sydney Report (2018) is organised around a common methodology in assessing Articles 7, 8, 10, 13, 14 and 47 of the LOSC concerning straight baselines, closing lines, and straight archipelagic baselines. Each analysis seeks to provide some background to the drafting of the Article, analysis of the text, assessment of state practice, relevant case law, and a summary of the commentary by publicists. The Report then moves to address certain cross-cutting or global issues that are relevant to a contemporary analysis of straight and archipelagic baselines, before reaching conclusions.
