The court will not add a person as a defendant to an existing action if the claim was already statute-barred and he wished to rely on that defence, and if the court allows such addition ex parte it will not, on objection allow the addition to stand. Where a defendant is added under Ord.15 r.6 there is no relation back so as to treat the added party as a defendant on any date earlier than he was in fact joined. Two reasons are used : ‘The first basis is that, if the addition were allowed, it would relate back, so that the action would be deemed to have been begun as against the person added, not on the date of amendment, but on the date of the original writ; that the effect of such relation back would be to deprive the person added of an accrued defence to the claim on the ground that it was statute-barred; and that this would be unjust to that person. I shall refer to this first basis of the rule of practice as the ‘relation back’ theory. The second and alternative basis for the rule is that, where a person is added as defendant in an existing action, the action is only deemed to have been begun as against him on the date of amendment of the writ; that the defence that the claim is statute-barred therefore remains available to him; and that, since such defence affords a complete answer to the claim, it would serve no useful purpose to allow the addition to be made. I shall refer to this second and alternative basis of the rule of practice as the ‘no useful purpose’ theory.’ As to which reason was correct, and referring to the rule in Sneade v Wotherton Barytes and Lead Mining Co as to relation back: ‘This seems to me to be an entirely sensible proposition so long as the amendment concerned does not involve the addition of a new party, either as plaintiff or defendant, or the raising of a new cause of action, but involves only the modification, by addition, deletion or substitution, of pleas or averments made between existing parties in respect of a cause or causes of action already raised. Where, however, the amendment concerned involves the addition of a new party or the raising of a new cause of action, it appears to me to be unrealistic and contrary to the common sense of the matter to treat it as relating back in the same way.’
