Juan Antonio Xiol was admitted to the judiciary through public competitive examination in 1972. In 1975, based on his academic merit as best student, he became a judicial-review judge, and in 1982 he served as secretary general of the Spanish Constitutional Court.
He has been a Supreme Court judge of the civil division and also the judicial-review division, presiding over its fourth and seventh chambers. He was elected a member of the General Council of the Spanish Judiciary, and subsequently its plenary commission appointed him as president of the civil division of the Supreme Court. He served as a Constitutional Court judge from June 2013 to December 2022. In November 2021, after a partial renewal of the Constitutional Court, the plenary commission appointed him vice president of the court, a position that he held until the end of his term of office in December 2022.
With an extensive and respected professional background, Xiol has also been managing director of relations at the Administration of Justice and is a member of the General Codification Commission.
