Appeals in Cassation and Other Special Appeals

Our team is made up of highly qualified and recognized experts that combine their knowledge of the procedural rules governing these appeals with their experience in the subject matters involved, covering civil, commercial, administrative, constitutional and EU law.

The Cassation Appeal Group specializes in designing, drafting and lodging (i) cassation appeals in the civil jurisdiction, (ii) state and regional cassation appeals in the contentiuous-administrative jurisdiction, and (iii) appeals for the protection of constitutional rights before the Constitutional Court. It also handles requests for preliminary rulings and their subsequent defense before the Court of Justice of the European Union and claims before the European Court of Human Rights.

In each appeal, we assign lawyers from other areas of the firm with expertise in the lawsuit’s subject matter to work alongside our procedural lawyers, who regularly appear before the high courts of justice, the Spanish Supreme Court, the Spanish Constitutional Court, the Court of Justice of the European Union and the European Court of Human Rights. This enables us to submit rigorous proposals to the courts, providing in-depth knowledge of the issues these courts will have to rule on and an approach tailored to the requirements of cassation and extraordinary appeals, the fulfillment of which are of central importance to their admissibility and success.

The team are immediately available and always provide effective legal ideas and strategies that are appropriate to each specific case.
