The Roman Rota, formally the Apostolic Tribunal of the Roman Rota (Latin: Tribunal Apostolicum Rotae Romanae), and anciently the Apostolic Court of Audience, is the highest appellate tribunal of the Catholic Church, with respect to both Latin-rite members and the Eastern-rite members and is the highest ecclesiastical court constituted by the Holy See related to judicial trials conducted in the Catholic Church. An appeal may be had to the pope himself, who is the supreme ecclesiastical judge. The Catholic Church has a complete legal system, which is the oldest in the West still in use. The court is named Rota (wheel) because the judges, called auditors, originally met in a round room to hear cases. The Rota was established in the 13th century.
