ABSTRACT
The duration of laws and their perpetual binding force have always been a central concern of philosophers and academics. In The Concept of Law , Hart discusses the persistence of law and observes that the Witchcraft Act 1735 was a legislative expression of some centuries ago, but was still in use until the middle of the 20th century. 1 The laws of past generations are the most prominent feature in the statute book and mark the life of present and future generations.
