EU judicial system

This subtopic contains a range of resources on the EU judicial system and the interpretation and enforcement of EU law.

A fundamental principle of EU law is the supremacy of EU law, also known as the primacy of EU law. Under this principle in the event of a conflict between EU law and national law, EU law is supreme and has primacy, irrespective of the source, status or date of the national law in question. Thus, EU law is also supreme over domestic constitutional provisions in the event of any conflict, but this has not been established without some concerns being raised by constitutional courts within the Member States. As originally drafted, the EU Treaties did not include any provision by which the supremacy of EU law was guaranteed. The Court of Justice has played a fundamental role in applying this principle and ensuring the uniform application of EU law across the Member States. For further reading, see Practice Note: The supremacy of EU law.

The European Commission’s role as 'Guardian of the Treaties' is to control the correct application of EU law across EU Member

Automated decision-making and DSARs: right to access means a right to explainability (CK v Magistrat Der Stadt Wiendun & Bradstreet Austria GMBH)

Information Law analysis: The Court of Justice provided several clarifications around the scope of data subject access requests (DSARs) in the context of automated decision-making. The court held the determining factor for whether information constitutes ‘meaningful information about the logic involved’ under Article 15(1)(h) of the EU’s General Data Protection Regulation, Regulation (EU) 2016/679 (EU GDPR) is whether the information enables the data subject to understand the logic involved in automated decision-making involving their personal data. The court also held disclosure by controllers should be underpinned by the principles of transparency, which requires information to be clear, accessible and intelligible, both in terms of content and form, from the perspective of data subjects. In the context of automated decision-making this doesn’t necessarily mean providing the exact algorithm, if it doesn’t help the data subject’s understanding of the ‘how’. The court confirmed DSARs do not mandate the disclosure of trade secrets, but this can only be decided by the relevant supervisory authority or competent court, after assessing all relevant information provided to them by a controller. The protection of trade secrets cannot be used as a blanket excuse by businesses to withhold certain information from individuals making a request under Article 15(1)(h) of the EU GDPR.

Commission reviews Health Emergency Preparedness and Response Authority operations

The European Commission has published a review of the Health Emergency Preparedness and Response Authority (HERA) on 27 March 2025, examining its operations since establishment in September 2021. The review assesses HERA's effectiveness in strengthening EU health security through medical countermeasure development, production and distribution. With €6bn funding through 2027, HERA coordinates threat assessment, research, stockpiling and crisis response. The review identifies areas for improvement including clearer delineation of responsibilities with other EU bodies and more tailored funding mechanisms. The Commission maintains HERA should remain an internal service rather than becoming a separate agency.
