The Supreme Court (Spanish: Tribunal Supremo, TS) is the highest court in the Kingdom of Spain. The court has original jurisdiction over cases against high-ranking officials of the Kingdom and over cases regarding the banning of political parties. It also has ultimate appellate jurisdiction over all cases. The Court also has the power of judicial review, except for constitutional matters, reserved to the Constitutional Court.
The Court was originally established pursuant to Title V of the Constitution of 1812 to replace the System of Councils in all matters that affected justice, and it is currently regulated by Title VI of the Constitution of 1978. As set in the Judiciary Organic Act of 1985, the Court consists of the President of the Supreme Court (who also chairs the General Council of the Judiciary), the Vice President, the Chairpersons of the Court's Chambers and an undetermined number of Magistrates (79 as of 2025). Each Magistrate of the Supreme Court is nominated by the General Council of the Judiciary and appointed by the Monarch for a lifetime tenure up to the age of 70, when they must retire (unless they request a 2-year extension).
