The concept of democracy has long fuelled controversy among international legal scholars, especially concerning its definition. This article is an attempt to single out three constitutive elements of democracy that have been subject to extensive scrutiny in the practice of electoral assistance and the more comprehensive peace-building and state-building missions that the UN has taken up or supported since the end of the twentieth century: freeand fair elections, freedom of association – with emphasis on the freedom to establish political parties – and freedom of expression. In doing so, this paper examines the role and the importance of each of these three constitutive elements in the practice pertaining to post-conflict reconstruction of Kosovo, East Timor, Afghanistan, and Iraq.
