How do international norms bring about constitutional and administrative change in apparently unreceptive environments? In South East Asia there is sensitivity to international law intruding on domestic sovereignty; a patchy tradition of constitutional democracy; and the central vehicle for international engagement, ASEAN, largely eschews binding norms. This panel nevertheless hypothesises that international norms have brought about significant change. ASEAN has prospered because it has contributed to the image of a particular form of State: the investee State. This model is characterised by four characteristics: growing central executives; normatively elaborate forms of network governance; significant reform of public administration used as a surrogate for legislative implementation of regional commitments; and a dual constitutional order in which the parliamentary and judiciary occupy one sphere and the executive and international actors the other.
