Thanks, that makes sense. Does anyone argue that Ferber is unconstitutional?

Tangentially, this raises a question that I've been meaning to ask you: am I right that the judiciary has had a far greater role in shaping the US, than it has in the UK? I mean, obviously neither body actually makes law, but it seems to me that parliamentary sovereignty has limited greatly what the judiciary can do, and thus I can't imagine the UK ever having had an equivalent of Roe V Wade or Brown V the Board of Education.
