A decree (Latin: decretum, from decerno, "I judge") is, in a general sense, an order or law made by a superior authority for the direction of others. In the usage of the canon law of the Catholic Church, it has various meanings. Any papal Bull, Brief, or Motu Proprio is a decree inasmuch as these documents are legislative acts of the Pope. In this sense the term is quite ancient. The Roman Congregations were formerly empowered to issue decrees in matters which come under their particular jurisdiction, but were forbidden from continuing to do so under Pope Benedict XV in 1917. Each ecclesiastical province, and also each diocese may issue decrees in their periodical synods within their sphere of authority.
