Injunctions in UK Law

In one or two other recent cases coming before this court, I have suspected signs of a growing tendency on the part of some litigants against whom ex parte injunctions have been granted, or of their legal advisers, to rush to the R. v. Kensington Income Tax Commissioners principle as a tabula in naufragio, alleging material non-disclosure on sometimes rather slender grounds, as representing substantially the only hope of obtaining the discharge of injunctions in cases where there is little hope of doing so on the substantial merits of the case or on the balance of convenience.

Situation (1) is when one party to an action can show that the other party has either invaded, or threatens to invade, a legal or equitable right of the former for the enforcement of which the latter is amenable to the jurisdiction of the court. Situation (2) is where one party to an action has behaved, or threatens to behave, in a manner which is unconscionable.

Where, however, the grant or refusal of the interlocutory injunction will have the practical effect of putting an end to the action because the harm that will have been already caused to the losing party by its grant or its refusal is complete and of a kind for which money cannot constitute any worthwhile recompense, the degree of likelihood that the plaintiff would have succeeded in establishing his right to an injunction if the action had gone to trial, is a factor to be brought into the balance by the judge in weighing the risks that injustice may result from his deciding the application one way rather than the other.

A right to obtain an interlocutory injunction is not a cause of action. It is dependent upon there being a pre-existing cause of action against the defendant arising out of an invasion, actual or theatened by him, of a legal or equitable right of the plaintiff for the enforcement of which the defendant is amenable to the jurisdiction of the court. The right to obtain an interlocutory injunction is merely ancillary and incidental to the pre-existing cause of action.

53, r. 1(2) being in identical terms, the subsection and the sub-rule must have the same meaning and the sub-rule, if it purported to extend jurisdiction, would have been ultra vires.

It may set aside the judge's exercise of his discretion on the ground that it was based upon a misunderstanding of the law or of the evidence before him or upon an inference that particular facts existed or did not exist, which, although it was one that might legitimately have been drawn upon the evidence that was before the judge, can be demonstrated to be wrong by further evidence that has become available by the time of the appeal: or upon the ground that there has been a change of circumstances after the judge made his order that would have justified his acceding to an application to vary it.

There must be facts from which the Commercial Court, like a prudent, sensible commercial man, can properly infer a danger of default if assets are removed from the jurisdiction.
