I think, speaking offhand and without full inquiry into the undoubted difficulties of legislation by reference, that the right hon. Member for Cambridge University (Mr. Rawlinson) is probably wrong in the point he made, in that all that we seek to do here is to repeal part of Section 4, Sub-section (1). That is all that is done, and the operative part of that Section remains. Therefore, I think there will be no difficulty on the point he has raised. However, I undertake during the Committee stage to clear up any point that has not been made plain to-night.
