2. Supremacy, direct effect, indirect effect, and state liability

This chapter discusses the key concepts within the EU legal order: supremacy, direct effect, indirect effect, and state liability. The doctrine of supremacy dictates that EU law takes precedence over conflicting provisions of national law. If a provision of EU law is directly effective, it gives rise to rights upon which individuals can rely directly in the national court. If an EU measure is not directly effective, a claimant may be able to rely on it through the application of indirect effect, which requires national law to be interpreted in accordance with relevant EU law. State liability gives rise to a right to damages where an individual has suffered loss because a Member State has failed to implement a directive or has committed other breaches of EU law.
