Council of Trent: Session XXV, Regulars and Nuns, Chapter IX

CHAPTER IX. Convents of Nuns immediately subject to the Apostolic See shall be governed by the Bishops; but others, by those deputed in the General Chapters, or by other Regulars.

Those convents of nuns which are immediately subject to the Apostolic See, even those which are called by the name of Chapters of St. Peter, or of St. John, or by whatsoever other name they may be designated, shall be governed by the bishops, as the delegates of the Apostolic See; anything to the contrary notwithstanding. But those which are governed, by persons deputed in general Chapters, or by other Regulars, shall be left under their care and conduct.
