Canon 551

What is prescribed in cann. 497 and 498 concerning dismissal or

expulsion shall apply to all members of orders and congregations.

The competent authority is the major superior having consulted

the council; if it concerns expulsions, with the consent of the

council. If there is danger in delay and there is no time to

reach the major superior, the local superior, with the consent of

the council, can expel a member, notifying at once the major

superior.
