Ordinary jurisdiction is contrasted with delegated jurisdiction, a temporary communication of power made by a superior to an inferior; thus we speak of a delegated judge and an ordinary judge.
ordinaries, though they have jurisdiction in the internal forum, for they have not jurisdiction in the external forum, being incapable of legislating and acting as judges; their administration is the exercise of paternal authority rather than of jurisdiction properly so called.
In practice, the determination of the persons included under the term ordinary is of importance in the case of indults and the execution of rescripts issued from Rome.
Parish priests, therefore, are not ordinaries, though they have jurisdiction in the internal forum, for they have not jurisdiction in the external forum, being incapable of legislating and acting as judges; their administration is the exercise of paternal authority rather than of jurisdiction properly so called.
As a rule ordinary jurisdiction is territorial as well as personal, as in the case of the pope and the bishops; but ordinary jurisdiction may be restricted to certain persons, exempt from the local authority.
Local ordinaries being unable personally to perform all acts of their jurisdiction may and even ought to communicate it permanently to certain persons, without however, divesting themselves of their authority; if the duties of these persons are specified and determined by law, they also are ordinaries, but in a restricted and inferior sense.
