48 In view of the conclusion we have reached it is unnecessary to consider the alternative ground that the appellant sought to raise, namely the substitution of Seiza Investments as plaintiff under O 18 r 7(2). We should, however, say in passing that, in our view, the finding of Deputy Registrar Harman that the operation of O 18 r 7(2) is limited to the circumstances set out in O 18 r 7(1), is, with respect, wrong. It is not so limited. In the circumstances, we are also, with respect, unable to agree with the conclusion of the learned deputy registrar that there is no warrant for the substitution of Seiza Investments as the plaintiff in the action. For the reasons we have given, following the perfection of the legal assignment of the debts by notice to the first respondent, Seiza Investments is the proper plaintiff in the action. However, as no appeal has been brought from the decision of the learned deputy registrar, it is unnecessary to say any more about it.
