This work investigates the legal status, function, and normative force of peremptory norms (jus cogens) within the framework of international public policy. Alexander Orakhelashvili, a scholar of international law, utilizes a rigorous analytical approach to evaluate how these non-derogable standards constrain the conduct of sovereign states. The text argues that peremptory norms serve as a fundamental check on state autonomy, effectively defining the boundaries of permissible international transactions and diplomatic objectives.

Legal scholars and practitioners frequently cite this text as a definitive resource for understanding the complexities of peremptory norms in modern jurisprudence. Readers often note the academic density of the prose, which is tailored for those with a background in international legal theory.
