European Union conditionality and the Acquis communautaire

The EU's conditions for the central and cast European applicants look deceptively straightforward: they comprise stable democracy, a competitive market economy, and the capacity to implement EU laws and policies (the so called acquis communautaire). However, they arc very general and not amenable to quantitative assessment, leaving ambiguity about exactly when they have been met. This ambiguity increases the EU's power in accession negotiations, but the accompanying uncertainty diffuses its influence in shaping institutional and policy choices. This article examines the EU's accession conditionality levers and the constraints on their use. It concludes that readiness for membership depends not only on technical progress in negotiations, but also on when the current member-states are politically ready for enlargement.
