Well I guess I'm of some utility if it's being violated in the District of Oregon.
What happens when a case spans multiple states? Do you seriously need to get licensed in each?
We'd either defend an enforcement action, which would be filed in federal court and heard by a magistrate judge, or bring a declaratory relief action in state or federal court concerning liability for fees on the NW Forest Pass, although if we filed in state (and why would we do that?) the feds would probably remove it to federal court. I could be admitted to neighboring federal court districts without being admitted in those states. the 9th Circuit's appellate ruling should be controlling law in all districts in the 9th circuit, which I believe includes WA, OR, CA, and ID, among others.
