Lisbon Treaty (No.1)

What slightly troubles me is that at the moment we envisage circumstances in which, for example, other countries are forced to do things in respect of child protection that we think right and proper; we think that that would be a good thing. However, can the Home Secretary not envisage circumstances in which we would be forced by qualified majority voting to do things that we would not think appropriate if we had decided on our own what should amount to a criminal offence and what should not? What could we do about that?
