State succession is a difficult area of international law, but the rules commonly associated with this field reflect certain general principles. The third preamble to the 1978 Vienna Convention on Succession of States in Respect of Treaties and to the 1983 Vienna Convention on Succession of States in Respect of State Property, Archives and Debts refers to the need for codification and progressive development in this area “as a means for ensuring greater juridical security in international relations”. This presentation advances, and tests, the thesis that the law of state succession to a greater or lesser extent reflects principles of continuity, stability and justice. These principles can assist in characterizing the purposes of the law of State succession across various areas, including treaties, property and nationality, and they are indicative of more general policies in international law.
