for procedural laws, establish interdiocesan tribunals, and correct advocates. The current Prefect is Dominique François Joseph Cardinal Mamberti. Tribunal of the Rota Romana The Tribunal of the Roman Rota is the highest appellate tribunal. While usually trying cases in appeal in third instance (as is normally the case in the Eastern Catholic Churches), or even in second instance if appeal is made to it directly from the sentence of a tribunal of first instance, it is also a court of first instance for cases specified in the law and for others committed to the Rota by the Roman Pontiff. It fosters the unity of jurisprudence and, through its own sentences, is a help to lower tribunals. The greater part of its decisions concern the nullity of marriage. In such cases its competence includes marriages between two Roman Catholics, between a Roman Catholic and non-Roman Catholic, and between two non-Roman Catholic parties whether one or both of the baptized parties belongs to the Latin or an Eastern Rite.
