SUPREMACÍA DE LA CONSTITUCIÓN VERSUS PRIMACÍA DEL DERECHO DE LA UE EN MATERIA DERECHOS FUNDAMENTALES: CONCORDANCIAS Y DISCORDANCIAS ENTRE EL TRIBUNAL CONSTITUCIONAL Y EL TRIBUNAL DE JUSTICIA DE LA UE EN EL ASUNTO MELLONI.

This paper surveys the first direct judicial dialogue between the Spanish Constitutional Court and the Court of Justice of the European Union on the European Arrest Warrant and the interpretation of Article 53 of the Charter of Fundamental Rights of the EU when the national level of protection of rights is higher than that provided by a rule of secondary legislation of the Union. It highlights the possible tensions between constitutional supremacy and primacy of European Union law, and the evocation made by the Constitutional Court of its doctrine on rights constitutionally recognized as limits to the European integration contained in the judgment which closes the dialogue between both Courts within the so-called Melloni case.
