Review Questions

  • How does the Court of Justice of the European Union contribute to the enforcement of EU law among member states?
    • The Court of Justice of the European Union contributes to enforcing EU law by interpreting treaties and ensuring consistent application across all member states. It hears cases brought by national courts, member states, or EU institutions, resolving disputes and clarifying legal interpretations. This process ensures that laws are uniformly applied, helping maintain legal coherence within the EU.
  • Discuss the relationship between national courts and the Court of Justice of the European Union in terms of preliminary rulings.
    • National courts have a significant relationship with the Court of Justice of the European Union through the process of preliminary rulings. When a national court encounters an issue related to EU law that requires interpretation, it can seek guidance from the CJEU. This mechanism allows for a unified interpretation of EU law, reinforcing its application across member states while also empowering national courts to ensure that local cases align with broader EU principles.
  • Evaluate the impact of CJEU's rulings on individual rights and member state sovereignty within the European Union.
    • The rulings of the Court of Justice of the European Union significantly impact individual rights by interpreting EU laws that protect those rights, such as freedom of movement and non-discrimination. While these rulings strengthen individual rights across Europe, they can sometimes challenge member state sovereignty, as national laws may be required to align with EU regulations. This dynamic creates a complex balance between upholding citizens' rights and respecting national autonomy within the broader context of EU governance.
