The purpose of this brief is precisely to evaluate the work of the Assembly in terms of oversight on implementation of legislation. The highest legislative body in the country has been subject to repeated criticism in the European Commission Country Report on Kosovo, for poor performance in its oversight role. The brief starts with an analysis of the legal framework that vests the Assembly with legislative oversight powers, to establish if there are gaps in this regard, and follows with a comparative analysis of different legislatures since 2008. Lastly, there is a review of reports adopted by the Assembly covering the oversight on implementation of legislation and an examination whether the provisions that could not be implemented in practice have been identified. Additionally, this paper examines the international practices in the oversight on implementation of legislation, respectively the efforts being made by parliaments in developed democracies, parliaments in neighboring countries and those aspiring European Union (EU) membership.
