Yes, that's right, I think. In the UK we have parliamentary sovereignty. As I understand it, no law and no court can stop Parliament from doing what it wants to do because every UK law can be amended by Parliament and every court merely applies those laws. (Courts may also apply international laws in some cases but the UK laws take priority and could override any foreign law.) The UK's Constitution is utterly terrible. In many places if you tried to implement something similar it would probably self-destruct very quickly. The UK manages to keep going with it (not brilliantly, but society hasn't completely collapsed yet) only because there is a strong democratic culture. That's my theory, anyway.
