Good. How does this apply to other states?
It won't apply to all states until SCOTUS rules it so.
But in the interim, if the 9th Circuit court upholds it, it will apply to its jurisdictional area:
District of Alaska
District of Arizona
Central District of California
Eastern District of California
Northern District of California
Southern District of California<> District of Hawaii
District of Idaho
District of Montana
District of Nevada
District of Oregon
Eastern District of Washington
Western District of Washington
