The Arizona Constitution contains the very strongest protection of private property rights in the nation. Arizona allows governments to condemn private property only for clearly defined public purposes, such as roadways and police stations, or certain very specific private purposes, such as a right of way or a drain. As written, that constitution gives Arizona property owners complete security against arbitrary condemnation and seizure by local governments.
Thus, taking of private property for the reason to generate more property tax is not a right recognized under the AZ Constitution.
Ever hear of SCOTUS? Your state constitution is a sitting duck for revision when the big boys get involved. Arizona might be a hold out, but it would have to secede from the nation before it could adequately safeguard this property rights issue. And as a landlocked area, it would simply get cut off from the rest of the world.
