Let me take any Dominion the hon. Member likes. I can only give the answer that has been given. It is possible to imagine many absurd situations. It is true that if any Dominion were to take that course —and I agree that it is theoretically possible to imagine it—the whole scheme would be likely to break down; but all I can say is that I do not believe any Dominion would legislate in that fashion. Let me also add that if they were minded to make crimes for which they would punish people when they came within their jurisdiction in the manner suggested, they could do it to-day and nobody could prevent them. If a Dominion cared to take a fantastic course, saying, "We will make it a crime for a member of another Dominion to do something in his own country, and we will punish him as soon as we can catch him when he lands on our shores," there is no power on earth to prevent that Dominion putting my hon. Friend in gaol.
