If you feel like initiating an interesting case-law scenario…
If the state would not permit you to claim residency for tuition purposes (I know USC is private, but the rules must be same), but expects you to claim residency for DMV, they would likely lose in federal court as the state cannot justly have two different standards for residency. Of course, it would have to go to SCOTUS, because we have corrupt system for circuit courts that lands local cronies in judicial robes with little or no vetting. So the 9th circuit is filled with Californians who typically side with state government over other entities or individuals.
