 Pope Pius VII, after his return to Rome, reformed the "Cancellaria" and prudently decreased its offices.But as he granted to the "vacabili" the privilege that, by a legal fiction, time of their tenures was regarded as not having transpired (""quod tempus et tempera non currant""), and many proprietors of "vacabili" having had obtained grants of "sopravivevza", by which deceased intestataries were regarded to be alive, some offices remained "vacabili" nominally, but not factually.Finally, in 1901 Pope Leo XIII abrogated all the "vacabili" offices and ordered his Prodatary to redeem them, when necessary substituting the office of the Apostolic Datary for their proprietors.
