There's a fundamental difference between what you describe and what I describe.
You describe an individual suing a state to win recognition of an out-of-state permit (the second state has no standing to seek enforcement of its own permits outside of its boundaries). That implicates individual rights.
I describe a state suing to invalidate a federal rule that requires interstate recognition. That doesn't necessarily implicate any individual right.
