Canon 479. §1 In virtue of his office, the Vicar general has the same executive power throughout the whole diocese as that which belongs by law to the diocesan Bishop: that is, he can perform all administrative acts, with the exception however of those which the Bishop has reserved to himself, or which by law require a special mandate of the Bishop.

§2 By virtue of the law itself, the episcopal Vicar has the same power as that mentioned in §1, but only for the determined part of the territory or type of activity, or for the faithful of the determined rite or group, for which he was appointed; matters which the Bishop reserves to himself or to the Vicar general, or which by law require a special mandate of the Bishop, are excepted.

§3 Within the limits of their competence, the Vicar general and the episcopal Vicar have also those habitual faculties which the Apostolic See has granted to the Bishop.
They may also execute rescripts, unless it is expressly provided otherwise, or unless the execution was entrusted to the Bishop on a personal basis.

§1. Vicario generali, vi officii, in universa dioecesi competit potestas exsecutiva quae ad Episcopum dioecesanum iure pertinet, ad ponendos scilicet omnes actus administrativos, iis tamen exceptis quos Episcopus sibi reservaverit vel qui ex iure requirant speciale Episcopi mandatum.

§2. Vicario episcopali ipso iure eadem competit potestas de qua in §1, sed quoad determinatam territorii partem aut negotiorum genus aut fideles determinati ritus vel coetus tantum pro quibus constitutus est, iis causis exceptis quas Episcopus sibi aut Vicario generali reservaverit, aut quae ex iure requirunt speciale Episcopi mandatum.

§3. Ad Vicarium generalem atque ad Vicarium episcopalem, intra ambitum eorum competentiae, pertinent etiam facultates habituales ab Apostolica Sede Episcopo concessae, necnon rescriptorum exsecutio, nisi aliud expresse cautum fuerit aut electa fuerit industria personae Episcopi dioecesani.
