“ [109]…..It is common ground that Paragon, as registered proprietor of the Legal Charge, retains legal ownership of it. One incident of its legal ownership – and an essential one at that – is the right to possession of the mortgaged property. I can see no basis upon which it can be contended that an uncompleted agreement to transfer the Legal Charge to the SPV (that is to say an agreement under which, pending completion, the SPV has no more than an equitable interest in the mortgage) can operate in law to divest Paragon of an essential incident of its legal ownership. In my judgment as a matter of principle the right to possession conferred by the Legal Charge remains exercisable by Paragon as the legal owner of the Legal Charge (ie as the registered proprietor of it), notwithstanding that Paragon may have transferred the beneficial ownership of the Legal Charge to the SPV. [110] It follows, in my judgment, that Paragon, so long as it remains the registered proprietor of the Legal Charge, is a necessary party to any claim to possession of the Property in right of the Legal Charge. [111] The only question then is whether the SPV should have been joined in the proceedings as an additional claimant. In my judgment, the answer to that question is plainly: No. On the assumption that the consideration for the transfer of the Legal Charge has been paid in full, Paragon has since retained its legal ownership of the Legal Charge as trustee for the SPV (see Whiteley v Delaney[1914] AC 132 at 141 per Viscount Haldane LC). But it does not follow that in that situation the SPV, as the owner of the Legal Charge in equity, is a necessary party to the claim; and on the facts of the instant case joinder of the SPV is wholly unnecessary. There is, after all, no issue between the SPV and Paragon as to the exercise of the mortgagee's rights under the Legal Charge: indeed the SPV has, by virtue of the administration agreements, expressly authorised Paragon to exercise such rights on its behalf. [112] In my judgment, therefore, there is no substance in the contention that the SPV should have been joined as an additional claimant in the proceedings. Nor, in my judgment, can the fact that Paragon has failed to describe itself as suing in its capacity as trustee affect the validity of the proceedings or of the orders made in the proceedings (in particular, the possession order). In any event, even if that failure could be said to amount to a formal defect in the proceedings (and I do not regard it as such) the court has ample powers under the CPR to correct such defects (eg under CPR Pt 17).”
“In my judgment the assignor still has a cause of action at law; and the assignee has a cause of action in equity. That was ultimately the position of Sir Patrick Neill in his reply, and I think that is right. It is the solution which is nearest to reconciling all the authorities. It allows the assignee still to use the assignor’s name, if he wishes, as before the Judicature Act. Of course the assignee’s claim prevails, if he insists upon it.The Supreme Court Act 1981 says so. But where the assignee is a party to the action, and expressly declines to make a claim, I can see no reason why the assignor should not claim what is his legal right….”
