This appointment, proposed by the General Council of the Judiciary and formalized by the Ministry of the Presidency, highlights the magistrate's career and specialization in international judicial cooperation. The role of the liaison judge is crucial for strengthening legal collaboration between countries, ensuring the application of conventions, and resolving cross-border disputes.

The Hague Conference is a leading intergovernmental organization focused on unifying private international law norms, covering critical areas such as child protection, family law, and the enforcement of foreign judgments. Magistrate Herrero Elejalde will combine this new international function with his duties in Puerto de la Cruz, thereby enhancing the external projection of the Canary Islands' justice system.

His initial term will be three years, with the possibility of extension, and it follows that of magistrate Ana del Ser, president of the High Court of Justice of Castilla y León. Herrero Elejalde possesses extensive experience in international judicial cooperation, international family law, and European networks, with advanced proficiency in English, French, and Italian. He joined the judicial career in 2012 and has served in various jurisdictions, including the Provincial Court of Santa Cruz de Tenerife.

In addition to his judicial work, the magistrate has participated in international conferences, authored specialized publications, and has been a lecturer at the University of La Laguna since the 2022-2023 academic year. He has coordinated European and international judicial networks and is an active member of REJUE and the International Cooperation Judicial Handbook Update Commission. Since 2024, he has represented Spain in the Eurojust Focal Group on Migrant Smuggling and has contributed to development cooperation projects in countries such as Serbia, Turkey, and Colombia.
