NULLAM LEGEM humanam ac positivam perpetuam esse; et clausula quae abrogatlonem excludit ab Initio non valet. It is a perpetual law that no human or positive law can be perpetual; and a clause in a law which precludes the power of abrogation is void ab initio. Bac. Max. reg. 19; Broom, Leg. Max. (3d London Ed.) 27.
