 When Pope Clement VII assigned this palace as the perpetual residence of the Vice Chancellor, he provided that the Vice Chancellor should always have the title of the Basilica; as the Chancellors were not always of the same order in the Sacred College, being either cardinal-deacons, cardinal-priests, or cardinal-bishops, this basilica could not follow the rule of the other cardinalitial titular churches that had the fixed grade of "titular" (a church over which a cardinal of the order of priests was placed) or "deaconry" (a church over which was placed a cardinal-deacon).The Basilica, on the contrary, became a titular for a Chancellor of the order of priests and a deaconry for one of the order of deacons; when the Chancellor was a suburbicarian bishop, he retained the Basilica "in commendam".The office of Regent, the next office in the order of precedence of the "Cancellaria Apostolica" after that of the Chancellor, was instituted in 1377, when Pope Gregory XI returned from Avignon, France to his see.
