mp, no court can issue an injunction to prohibit enforcement of the new laws until someone has actually challenged the new law. It doesn't matter that the new laws are "substantially identical" to the old ones. Unless and until someone challenges the new law, regardless of how closely it tracks the old one, there's no "case or controversy" for the courts to hear.
I'm a lawyer, but I'm not your lawyer. If you need some honest-to-goodness legal advice, go buy some.
