>The U.S. Supreme Court in Crandall v. Nevada, 73 U.S. 35 (1868) declared that freedom of movement is a fundamental right and therefore a state cannot inhibit people from leaving the state by taxing them.
I'm having a hard time finding a controlling case that says states can't do the inverse, i.e. levy fees on those who want to move to their state. I don't have the time tonight to read the whole case and its references, but I'm happy to be proven wrong here. Levying a fee on people who move in seems a perfectly reasonable thing to do. After all, we all have to pay move-in fees when we lease a new apartment or buy a house.
