Extravagantes

[1] The term was first applied to those papal documents which Gratian had not inserted in his "Decree" (about 1140), but which, however, were binding upon the whole Church, also to other decretals of a later date, and possessed of the same authority.

Even the Decretals of Gregory IX (published 1234) were long known as the "Liber" or "Collectio Extra", i.e. the collection of the canonical laws not contained in the "Decree" of Gratian.

[1] When Pope John XXII (1316-1334) published the decretals known as the Clementines, there already existed some pontifical documents binding upon the whole Church but not included in the "Corpus Juris".

Their number was increased by the inclusion of all the pontifical laws of later date, added to the manuscripts of the "Corpus Juris", or gathered into separate collections.

On the other hand, many of the decretals included in them contain legislation binding upon the whole Church, e.g. the Constitution of Paul II, "Ambitios", which forbade the alienation of ecclesiastical goods.
