In The Juridical Nature of Unilateral Acts of States in International Law Eva Kassoti explores the question of the legal nature of unilateral acts by focusing on their essential characteristics, namely unilateralism and the manifest intention to be bound. By analysing the legal and factual context surrounding the making of unilateral acts, this volume offers a list of indicators of the elements of unilateralism and manifest intention that will facilitate the determination of the existence of a unilateral juridical act in practice. Kassoti explores the legal nature of unilateral acts from the viewpoint of the theory of international juridical acts and thus, attests to the validity of this theory as a comprehensive framework for the analysis of all juridical acts in international law.
