It is now unquestionable that corruption has become an issue of international concern. A complex set of substantive and procedural rules has emerged concerning the prevention and repression of corruption, representing the international legal framework against corruption. The present study begins by tracing the emergence of this framework and engages in a systematic analysis of its content, highlighting weaknesses and innovative aspects. What does international law require States to do in relation to corruption? What happens if States do not meet their international obligations? The responses to these questions constitute the core of this study.
