International organizations have been described metaphorically as the Frankenstein of international law. They are created by states and yet more often than not they assume powers that humble their creators. This paper presents a different metaphor to describe the Association of Southeast Asian Nations [ASEAN]. Created in 2007, ASEAN, it is argued, resembles the fettered wayang kulit in Indonesian theatre. It is an international organization which is controlled by its Member States in various ways. This paper analyzes three forms of ASEAN's fetters: constitutional, extra-constitutional, and practical. Constitutional fetters refer to the structural control embedded in the ASEAN Charter. Extra-constitutional fetters refer to rules of procedure that close the openness of the constitutional text. Finally, practical fetters refer to the ways the Member States limit ASEAN's legal personality in practice. Through these control mechanisms, ASEAN has so far acted on the stage of world politics according to the narrative of its puppet masters.
