House Decisions binding on Itself
The House laid down principles for the doctrine of precedent. When faced with the hypothesis that a case might have been decided in ignorance of the existence of some relevant statutory provision or in reliance on some statutory provision which was subsequently discovered to have been repealed, Lord Halsbury suggested that it would not be a binding authority because it was founded on a mistake of fact.
‘a decision of this House once given upon a point of law is conclusive upon this House afterwards, and that it is impossible to raise that question again as if it was res integra and could be reargued, and so the House be asked to reverse its own decision. That is a principle which has been, I believe, without any real decision to the contrary, established now for some centuries, and I am therefore of opinion that in this case it is not competent for us to rehear and for counsel to reargue a question which has been recently decided.’
