Pickin v British Railways Board (1974) AC 765
“When an enactment is passed there is finality unless and until it is amended or repealed by Parliament. In the Courts there may be argument as to the correct interpretation of the enactment: there must be none as to whether it should be on the statute book at all.
In earlier times many learned lawyers seemed to have believed that an Act of Parliament could be disregarded in so far as it was contrary to the law of God or the law of nature or natural justice, but since the supremacy of Parliament was finally demonstrated by the Revolution of 1688 any such idea has become obsolete. The idea that a court is entitled to disregard a provision in an Act of Parliament on any ground must seem strange and startling to anyone with any knowledge of the history and law of our constitution.”
