The 1983 Code of Canon Law (abbreviated 1983 CIC from its Latin title Codex Iuris Canonici), also called the Johanno-Pauline Code, is the "fundamental body of ecclesiastical laws for the Latin Church". It is the second and current comprehensive codification of canonical legislation for the Latin Church sui juris of the Catholic Church. It was promulgated on 25 January 1983 by John Paul II and took legal effect on the First Sunday of Advent (27 November) 1983. It replaced the 1917 Code of Canon Law, promulgated by Benedict XV on 27 May 1917.
The current Code of Canon Law is the second comprehensive codification of the non-liturgical laws of the Latin Church, replacing the Pio-Benedictine code that had been promulgated by Benedict XV in 1917. See also Canon Law-Codification and Code of Canons of the Eastern Churches.
Pope John XXIII, when proclaiming a new ecumenical council for the Catholic Church, also announced the intention of revising the 1917 CIC. It was not feasible to revise the Code of Canon Law until after the conclusion of the Second Vatican Council, so that the decisions of the Council could guide the revision of ecclesiastical laws. Several of the council documents gave specific instructions regarding changes to the organization of the Catholic Church, in particular the decrees Christus Dominus, Presbyterorum Ordinis, Perfectae Caritatis, and Ad gentes. In 1966, Pope Paul VI issued norms to apply these instructions through the motu proprio Ecclesiae Sanctae.
