Marleasing case

The Marleasing case established a key legal principle in the European Union: national courts must interpret their country’s laws in a way that aligns with EU directives, even if the country's own laws are silent or ambiguous about EU rules. Essentially, it means that when applying national law, courts should interpret it as compatible with EU law to ensure consistent implementation across member states. This case reinforced the idea that EU laws have priority over conflicting national laws, promoting uniformity and effectiveness of EU policies throughout member countries.
