REGULAE JURIS
Certain legal axioms, ninety-nine, from the Decretals of Popes Gregory IX and Boniface VIII. They were rules of canonical interpretation, for example, "once bad always presumed to be bad," i.e., if once proved guilty of perjury, a person would be excluded from giving testimony ever again.
