This work investigates the role of the gravity principle in establishing the legitimacy of international criminal law within the global community. Margaret M. deGuzman, a professor of law, utilizes historical analysis and legal theory to argue that the concept of gravity—the severity of a crime—serves as a critical, yet under-examined, mechanism for defining the scope and authority of international tribunals. By examining how gravity influences prosecutorial discretion and sentencing, the author provides a framework for understanding how international courts justify their intervention in domestic affairs.

Legal scholars and practitioners frequently cite this text as a foundational exploration of the gravity principle's normative function in international courts. Experts highlight the author's ability to synthesize complex jurisdictional theory into a coherent argument regarding the legitimacy of global legal institutions.
