"... a judgment must be set aside and declared a nullity by the court in the exercise of its inherent jurisdiction if and as soon as it appears to the court that the person named as the judgment debtor was at all material times at the date of writ and subsequently non-existent."
"... the cause of action was vested in Mr Fielding when the writ was issued and there has never been a stage at which the cause of action has not been vested in a living and existing party. The defect which did take place was that, at the date of service, the name of the action had not been amended so as to show the plaintiff as the party upon whom the right of action of the deceased had devolved. That, as it seems to me, is an irregularity which is well within the powers of the court to make good under RSC, Ord 2, r 1(2). In other words there was, I think, a departure from the correct procedure in this case, but not one which went to the root of the proceedings so as to render them a nullity, simply an irregularity which is well within the powers of the court to rectify."
