The article deals with the reform of the Roman Curia, implemented in 2022 by the Apostolic Constitution Praedicate Evangelium of Pope Francis. It does not deal with the redefined structure of the Roman Curia, but places this reform in a broader his- torical context, with an emphasis on comparison with the previous regulations of Popes Sixtus V in 1588, Pius X in 1908, the first Code of Canon Law of 1917, and the two pre- vious reforms after the Second Vatican Council, of Pope Paul VI in 1967 and John Paul II in 1988. It shows both the partial continuity of Pope Francis’ reform and the preceding juridical regulations, as well as his new emphases, and the partial juridical discontinu- ity that leads to a discrepancy in canon law between the provisions of the 1983 Code of Canon Law and the 1990 Code of Canons of the Eastern Churches, on the one hand, and Pope Francis’ Apostolic Constitution, on the other. This will have to be addressed in the future, either by further changes in the structure of the Roman Curia or by amend- ing the provisions of the two existing Codes.
