In a decree of the Second Vatican Council, it was recommended that dioceses be reorganized to take into account modern developments.
A project begun on orders from Pope John XXIII, and continued under his successors, was intended  to reduce the number of dioceses in Italy and to rationalize their borders in terms of modern population changes and shortages of clergy.
The change was made urgent because of changes made to the Concordat between the Italian State and the Holy See on 18 February 1984, and embodied in a law of 3 June 1985.
The change was approved by Pope John Paul II in an audience of 27 September 1986, and by a decree of the Sacred Congregation of Bishops of the Papal Curia on 30 September 1986.
The dioceses of Belluno and Feltre, which had up to that point shared a single bishop while retaining two diocesan structures, were united into a single diocese.
Its name was to be Dioecesis Bellunensis-Feltrensis.
The seat of the diocese was to be in Belluno.
The former cathedral in Feltre was to have the honorary title of co-cathedral, and its Chapter was to be the Capitulum Concathedralis.
There was to be only one episcopal curia, one seminary, one ecclesiastical tribunal; and all the clergy were to be incardinated in the diocese of Belluno-Feltre.
