The Vicar General assists the Bishop in the governance of the diocese.
The Vicar General possesses by virtue of his Office the same executive power as the Bishop throughout the whole diocese as belongs by law to the Bishop. This means that the Vicar General can perform all administrative acts as the Bishop does, with the exception of those administrative acts which the Bishop has reserved to himself, or which by law requires a special mandate of the Bishop (Canon 479 §1).)
