"The question is, is it a good law or not?"

OK, that's easy: Yes. It is a good law. I guess I was reading you loosely as complaining that they had no right to do that. Obviously, they do. Actually, your brief question above still addresses that: There are two ways a law can be considered good. Either it does some good thing, or it is a law which has been written and passed in an appropriate manner so that it won't be overthrown. Yeah, I know: you don't like that observation either.
