Dismissal of a member of the institute proceeds pursuant to cann. 694 §1, 1 and 2; and 695. The constitutions may also define other causes for dismissal, provided that they be commensurately serious, external, attributable and juridically proven, and that the procedure established in cann. 697-700 also be observed. The provisions of can. 701 are applicable to the dismissed member.
