In view of the particular character of the function of a legate:
1/ the seat of a pontifical legation is exempt from the power of governance of the local ordinary unless it is a question of celebrating marriages;
2/ after he has notified in advance the local ordinaries insofar as possible, a pontifical legate is permitted to perform liturgical celebrations in all churches of his legation, even in pontificals.
