 An Apostolic Administrator and, provided they have the consent of certain groups, certain other ecclesiastics provisionally in charge of a diocese can also issue such letters.For ordination to diaconate or priesthood of a member of a religious institute, the major superior of the institute gives the letters, if the person to be ordained is a permanently professed member of the institute; all other members must obtain their dimissorial letters in the same way as the secular clergy do..In a mixed congregation of men (both priests and brothers) only a priest can be elected to be the major superior (superior general) and only a cleric that is superior general can issue a dimissorial letter.
