In which case Lord Halsbury observed ?

“Of course, I do not deny that cases of individual hardship may arise, and there may be a current of opinion in the profession that such and such a Judgement was erroneous; but what is that  occasional interference with what is perhaps abstract justice, as compared with the inconvenience-the disastrous in convenience- of having each question subject to being re-argued and the dealings of mankind rendered doubtful by reason of different decisions, so that in truth and in fact there would be no real final court of appeal. My Lords, “interest republican” that there should be ‘finish litium’ sometime and there could be no ‘finis tutium’ if it were possible to suggest in each case that it might be re-argued because it is not an ordinary case’ whatever that may mean’.
