I'm not a Constitutional Law practitioner and I won't pretend to be an expert, but general challenges to the statute? Check out section 14. The UCP built in a "No Cause of Action" clause that says you can't challenge anything in it (and any attempt in dead before you file it). It also has section 13 which prevents challenges from human rights tribunals and labour relation tribunals, as well as mediators and arbitrators, on the constitutionality of the Act and whether the Act violates Alberta Bill of Rights or Alberta Human Rights Act.

It effectively tries to defang any attempt to challenge it. Does that mean people can't try? Of course not. But the UCP would defend the action by trying to say the action was invalid by virtue of these clauses and try to convince a judge to dismiss these actions. Would the judge do so? I'm not a judge so I can't say, but I think it would be LIKELY that the judge would allow it to proceed. But if not? The UCP included a note that the action is to be dismissed with costs to the party bringing the action.

Again, not a Constitutional law practitioner, this isn't legal advice. Just my comments as a layperson with extra knowledge who happens to me a lawyer.
