The Eclipse of the Legality Principle in the European Union

Legality is a traditional normative concept to regulate the relationship between those in power and those subjected to that power. The principle of legality protects the citizen against the arbitrary use of power, or, more precisely, it demands a legal basis (which itself must be of a certain standard) to legitimize State action. Is legality under siege in Europe? The authors contributing to this provocative and important book answer this question in the affirmative.
