The Vatican Tribunal is composed of two main components: the ROTA and the Curia. The ROTA is a judicial body that hears appeals from lower courts in the Catholic Church. It is composed of three judges, who are appointed by the Pope. The Curia is the administrative arm of the Vatican, responsible for the day-to-day running of the Holy See. It is composed of several departments, including the Secretariat of State, the Congregation for the Doctrine of the Faith, and the Pontifical Council for Justice and Peace. Together, the ROTA and the Curia form the Vatican Tribunal, which is responsible for the administration of justice within the Catholic Church.
