The Roman Rota, formally the Apostolic Tribunal of the Roman Rota, and anciently the Apostolic Court of Audience, is the highest appellate tribunal of the Catholic Church, with respect to both Latin Church members and the Eastern Catholic 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.

Latin is a classical language belonging to the Italic branch of the Indo-European languages. Considered a dead language, Latin was originally spoken in Latium, the lower Tiber area around Rome. Through the expansion of the Roman Republic it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the early 19th century, when regional vernaculars supplanted it in common academic and political usage—including its own descendants, the Romance languages. For most of the time it was used, it would be considered a dead language in the modern linguistic definition; that is, it lacked native speakers, despite being used extensively and actively.
