The State Advocate on leave of absence joins the firm as a partner to lead the project to open a new office

Pérez-Llorca announced today the appointment of Sonsoles Centeno as a partner of the firm. Centeno will lead the opening of a new office in Brussels, which is scheduled to take place in the second half of 2022.

A significant portion of Pérez-Llorca’s business revolves around advising large Spanish companies on matters related to public law, competition law and European Union law. The firm has a unique presence in litigation before the Court of Justice of the European Union in Luxembourg. It is also involved in numerous matters and proceedings before the European Commission and in the EU’s regulatory development processes, which means that its partners are often in Brussels. By opening the new office, Pérez-Llorca will have a permanent base in the city and will increase its capacity to take on more work.

A State Advocate on leave of absence and an expert in European Union law, Centeno has in-depth knowledge of the European institutions and has more than 18 years of experience in different positions working for the Government. Prior to joining the firm, she was Deputy Director General for European Union and International Affairs (Ministry of Justice), Chief State Advocate before the Court of Justice of the European Union (Ministry of Foreign Affairs, European Union and Cooperation) and Agent of the Kingdom of Spain. Her responsibilities included being in charge of directing legal advice on European Union law within the State Advocate’s Office, managing the team of the State Advocate’s Office, both in Madrid and in Brussels, as well as defending and representing Spain before the Court of Justice in the most sensitive cases.

Previously, she held the position of State Advocate-Legal Adviser at the Permanent Representation of Spain to the European Union in Brussels, acted before the General Court of the European Union, and was State Advocate before the National High Court (Administrative Chamber), and before the Central Administrative Courts.
