Extravagantes

The term Extravagantes (from the Latin extra, outside; vagari, to wander) is applied to the canon law of the Roman Catholic Church, to designate some papal decretals not contained in certain canonical collections which possess a special authority. More precisely, they are not found in Gratian's 'Decretum or the three official collections of the Corpus Juris Canonici (the Decretals of Gregory IX, the Sixth Book of the Decretals, and the Clementines).
