Bill's legal advisers are wise to note that the state doesn't have any power to amend the 25-mile rule because it was already in the ballot initiative. In a nutshell, if the state could change the law to remove the 25 mile restriction, there isn't any element of the law that they couldn't change. Meaning, they could end the program altogether, and trust me, if this legislature could do that, they would have done it. But AZ state law doesn't allow for that kind of amendment, fortunately or unfortunately, for a voter-initiated ballot proposition that becomes law.
Removing the 25-mile rule will require a separate ballot initiative to amend the AMMA. If we could do that, we could just legalize. Or end up losing the AMMA that we have now. Let's not forget that it _barely_ passed, and that a lot of the people who voted for it have left the state for greener pastures in the last few years, and that right-wing activism is at an all time high this election year.
