“That was an exercise of discretion and that, of course, is an obstacle to an appeal against the judge’s decision. But I am bound to say that, in my view, he was abundantly right. I say that because, as it seems to me there is all the difference in the world between proceedings in this country, whether by litigation or by arbitration, to determine rights of parties on the one hand, and proceedings in this country to enforce rights which have been determined by some other court or arbitral tribunal outside the jurisdiction. Where this court is concerned to determine rights then it will, in an appropriate case, and certainly should, enforce its own judgment by exercising what would be described as a long arm jurisdiction. But, where it is merely being asked under a convention or an Act of Parliament to enforce in support of another jurisdiction, whether in arbitration or litigation, it seems to me that, save in an exceptional case, it should stop short of making orders which extend beyond its own territorial jurisdiction. I say that because, if you take a hypothetical case of rights being determined in state A and assets being found in states B to M, you would find a very large number of subsidiary jurisdictions – in the sense that they were merely being asked to enforce the rights determined by another jurisdiction – making criss-crossing long arm jurisdictional orders with a high degree of probability that there would be confusion and, indeed, resentment by the nations concerned at interference with their jurisdictions. It seems to me that, apart from the very exceptional case, the proper attitude of the English courts – and, I may add, courts in other jurisdictions – is to confine themselves to their own territorial area, save in cases in which they are the court or tribunal which determines the rights of the parties. So long as they are merely being used as enforcement agencies they should stick to their own last.”
