cessante ratione legis cessat ipsa lex

cessante ratione legis cessat ipsa lex

‘the law itself ceases if the reason of the law ceases,’ a controversial doctrine that has, on the face of it, reason on its side. The difficulty, especially in a case-based system, is to agree upon what is the rationale of the law. The application of the doctrine runs contrary to the fundamental doctrine of the English common law, STARE DECISIS.
