The Supreme Tribunal of the Apostolic Signatura () is the highest judicial authority in the Catholic Church (apart from the pope himself, who as supreme ecclesiastical judge is the final point of appeal for any ecclesiastical judgment). In addition, it oversees the administration of justice in the church. Since 8 November 2014, the prefect of the Supreme Tribunal of the Apostolic Signatura has been Cardinal Dominique Mamberti. Its secretary since 26 January 2022 has been Bishop elect Andrea Ripa. The Supreme Tribunal of the Apostolic Signatura is housed in the Italian Renaissance-era Palazzo della Cancelleria in Rome, Italy, which also is the headquarters and meeting place of the Roman Catholic Church's other two Tribunals. The Apostolic Signatura only hears appeals from these two tribunals (which normally have final and universal [worldwide Church] appellate jurisdiction over their respective areas of competence) if some process was in error or there is an inter-agency conflict, and usually not in regard to the judgment which was made or the merits of the case. The two other Tribunals located there are the Sacred Roman Rota (which is normally the final appellate tribunal of the church for most court cases, especially regarding marriage nullity, decisions of bishops, and ecclesiastical trials and disciplinary procedures), and the Apostolic Penitentiary (which is normally the final appellate tribunal regarding all matters having to do with the forgiveness of sins and the proper celebration of the Sacrament of Reconciliation). Field of competence The Roman Rota is the ordinary appellate tribunal of the Apostolic See. The Signatura's competence covers: complaints of nullity and petitions for total reinstatement against sentences of the Roman Rota; recourses, in cases concerning the status of persons, when the Roman Rota has denied a new examination of the case; exceptions of suspicion and other proceedings against judges of the Roman Rota arising from the exercise of their functions; conflicts of competence between tribunals which are not subject to the same appellate tribunal. Apart from these judicial matters, the Signatura has the competence as an administrative tribunal to deal with controversies over administrative decisions made by or approved by dicasteries of the Roman Curia if it is contended that the decision violated some law, either in the decision-making process or in the procedure used. It can also deal with administrative controversies referred to it by the Pope or those departments, and with conflicts of competence between the departments. A
