Pope Leo XIII reformed the organization of the Dataria to conform it to contemporary requirements.
Pope Pius X reduced its faculties and re-organized it in his
apostolic constitution Sapienti Consilio, according to which the Dataria consisted of the Cardinal Datary, the Subdatary, the Prefect and his Surrogate (
Sostituto), a few officers, the Cashier who was
ex officio the Distributor, the Reviser, and 2 scribes of
Papal bulls.
Sapienti Consilio retained the theological examiners for the competitions for parishes. Among the abrogated offices was that of the
Apostolic Dispatchers, for which there was no rationale in the re-organization of the
Roman Curia: formerly these officials were necessary because private persons could not refer directly to the Dataria, which dealt only with persons of whom it approved, but later any person could deal directly with it and any other departments of the
Roman Curia. To the Dataria, which was commissioned to grant many Papal
indults and favors, remained only the faculties to investigate the fitness of candidates for Consistorial
benefices, which were reserved to the
Apostolic See; to write and dispatch the Apostolic Letters for the collation of those benefices; to dispense from the conditions of those benefices; and to provide for the pensions or for the execution of the charges imposed by the Pope in the collation of those benefices. The procedures of the Dataria were complex and primarily regulated by customs, which the officials of the Dataria zealously guarded, being generally
laity, and who had by such guarding instituted a species of monopoly of the faculties of the Dataria, as detrimental to the
Apostolic See as it was personally profitable to them. Thus it happened that its offices often descended from father to son, while the ecclesiastical superiors of such officials were to a great extent blindly dependent upon them.
Pope Leo XIII initiated the reform of this condition of things before
Pope Pius X totally rectified it. ==Abrogation==
