In which case Lord M.R. Denning Said ?

“I do not think we are bound by prior decisions of our own, or at any rate, not absolutely bound. We are not fettered as it was once thought. It was a self-imposed limitation ; and we who imposed it can also remove it. The House of Lords have done it. So why should not we do like-wise. We should be just as free no more  and no less to depart from a prior precedent of our own as in a like case is the House of Lords or judge of first instance”.
