“(2) The court may order a person to be added as a new party if – (a) it is desirable to add the new party so that the court can resolve all the matters in dispute in the proceedings; or (b) there is an issue involving the new party and an existing party which is connected to the matters in dispute in the proceedings, and it is desirable to add the new party so that the court can resolve that issue.”
“66. If a claimant seeks to raise a new claim by amendment and the defendant objects that it is barred by limitation, the court must decide how to proceed. There are two options. First the court could deal with the matter as a conventional amendment application. Alternatively, the court could direct that the question of limitation be determined as a preliminary issue. 67 If, as is usually the case, the court adopts the first option, it will not descend into factual issues which are seriously in dispute. The court will limit itself to considering whether the defendant has a “reasonably arguable case on limitation”: see WDA at 1425 H. If so, the court will refuse the claimant's application. If not, the court will have a discretion to allow the amendment if it sees fit in all the circumstances. 68 If the court refuses permission to amend, the claimant's remedy will be to issue separate proceedings in respect of the new claim. The defendant can plead its limitation defence. The limitation issue will then be determined at trial and the defendant will not be prejudiced by the operation of relation back under section 35 (1) of the 1980 Act. 69 This leads on to a separate and important point. If a claimant applies for permission to amend and the amendment arguably adds a new claim which is statute barred, then the claimant should take steps to protect itself. The obvious step is to issue separate proceedings in respect of the new claim. This will have the advantage of stopping the limitation clock on the date of the new claim form. If permission to amend is granted, then the second action can be allowed to lapse. If permission to amend is refused, the claimant can pursue his new claim in the second action. The two actions will probably be consolidated and the question of limitation can be determined at trial. 70 I turn now to the second option. This is for the court to determine the question of limitation as a preliminary issue at the same time as considering whether to give permission to amend. In practice, this course will seldom be appropriate. Before ordering any trial of preliminary issues, the court must carefully consider the ramifications of such an order. Will the same witnesses have to give evidence on related topics at two different trials? What will be the consequence if there is an appeal on the preliminary issue? Will the separation out of preliminary issues ultimately lead to a saving or a wastage of time and costs? Particular problems attach to an order for the trial of preliminary issues before the pleadings are complete. Having said all that, I must accept that there are some rare cases where the court will order trial of the limitation issue before deciding whether to give permission to amend.”
