The question can be raised whether the principal effect of interactive policy development is to shore up a (creaking) democratic system or to destabilize its very foundations. In this article, a framework is presented for assessing the democratic credentials of interactive policy development. It is based on four views on how a democracy should work: instrumental or substantial democracy and direct or indirect democracy. Critics and advocates differ in their confidence that the intended aims can ever be realized. Based on extensive case study material of interactive local policy development projects collected between 1997 and 2001, the validity of the various arguments for or against interactive policy-making is analysed. The analysis indicates that whether interactive policy development undermines or sustains democracy depends principally on the extent to which divergences in the expectations of the various groups are made explicit and unrealistic or mistaken expectations are dispelled.
