Perspectives on Katanga: An Introduction

The principle of complementarity is one the cardinal features of the architecture of the Rome Statute. Complementarity provides not only a forum to advocate overlapping competencies and litigate jurisdictional disputes over admissibility (e.g. Articles 17 and 19), but marks the foundation of the Statute as a multidimensional system of justice (e.g. Preamble, Article 1). This topic has been a focus of attention of the Court since its very inception. When taking office, the Prosecutor of the International Criminal Court (ICC), Luis Moreno-Ocampo, qualified complementarity as one of the key factors for the successful operation of the Court, noting that ‘the absence of trials led by [the] Court as a consequence of the regular functioning of national institutions would be a major success’. As of 2003, the Office of the Prosecutor (OTP) has developed guidelines and principles on complementarity in order to clarify its theoretical underpinnings and operational features.
