"If the action had been brought within time, it would have been irrelevant that by reason of the delay in commencing the action, Dr Chang might have had little independent recollection of his conversation with the applicant and that the defendant might have had difficulty in fairly defending itself. But once the potential liability of the defendant has ended, its capacity to obtain a fair trial, if an extension of time were granted, was relevant and important. To subject a defendant once again to a potential liability that has expired may often be a lesser evil then to deprive the plaintiff of the right to reinstate the lost action. This will often be the case where the plaintiff is without fault and no actual prejudice to the defendant is readily apparent. But the justice of the plaintiff's claim is seldom likely to be strong enough to warrant a Court reinstating a right of action against the defendant who, by reason of delay in commencing the action, is unable to defend itself or is otherwise prejudiced in fact and who is not guilty of fraud, deception or concealment in respect of the existence of the action."
