§1. The general chapter, which holds supreme authority in the institute according to the norm of the constitutions, is to be composed in such a way that, representing the entire institute, it becomes a true sign of its unity in charity. It is for the general chapter principally: to protect the patrimony of the institute mentioned in can. 578, promote suitable renewal according to that patrimony, elect the supreme moderator, treat affairs of greater importance, and issue norms which all are bound to obey.
§2. The constitutions are to define the composition and extent of the power of a chapter; proper law is to determine further the order to be observed in the celebration of the chapter, especially in what pertains to elections and the manner of handling affairs.
§3. According to the norms determined in proper law, not only provinces and local communities, but also any member can freely send wishes and suggestions to a general chapter.
