Researching the E.U. Court of Justice and E.U. caselaw

The European Union Court of Justice issues judgments and order interpreting the E.U. treaties and legislation.  Cases can be brought by E.U. institutions, member states, and individuals against E.U. institutions; against E.U. member states for failing to fulfill their treaty obligations; and by national courts requesting preliminary rulings on the validity or interpretations of E.U. law. The General Court hears administrative disputes and competition cases.

Documents from the Court of Justice can be found in:
