Direct Effect in EU Law

Direct Effect in EU Law thoroughly examines the principle of direct effect, which enables individuals and companies to invoke their rights before domestic courts. Emphasizing the need for the CJEU to fully articulate and systematize direct effect, it ultimately puts forward solutions for its principled comprehension and enforcement.

Direct Effect in EU Law is the first book in English to thoroughly examine this revolutionary legal principle, tracing direct effect's evolution from its inception during EU legal integration. A founding doctrine of EU constitutional law and the driving force of the EU legal system, direct effect enables individuals and companies to invoke their rights before domestic authorities and the Court of Justice of the EU (CJEU). Yet, while the doctrine of direct effect remains the backbone of the EU legal system, it lacks clear legal framing by the CJEU.

Emphasizing the need for the CJEU to fully articulate and systematize direct effect as to its core components and consequences, the book advocates for an innovative understanding of such principle that acknowledges its transformative impact on EU law. It bridges theory and practice, drawing from CJEU judgements from the 1950s to 2024. The book reconstructs direct effect beyond the doctrine originating from Van Gend & Loos, and ultimately puts forward solutions for its principled comprehension and enforcement.
