Arizona: Citizenship mandate challenged | SCOTUSblog
Challengers to Arizona’s eight-year-old mandate that voters must prove that they are U.S. citizens before they may register to go to the polls argued Monday that the state has not offered any evidence that the requirement is necessary to prevent fraud in elections. Urging the Supreme Court to leave undisturbed a Ninth Circuit Court decision striking down the citizenship rule, the opponents of Arizona’s “Proposition 200″ contended that a delay of that ruling will interfere with voting in this year’s elections and drive potential voters away from the polls. Two responses to Arizona’s plea for postponement can be read here and here. The state’s voters approved the citizenship mandate in 2004, and its enactment has led to a continuing courthouse battle that has been to the Supreme Court once before, and even led to an earlier Ninth Circuit ruling against the requirement by retired Justice Sandra Day O’Connor, sitting temporarily as a federal appeals court judge. Indeed, her name was invoked by the challengers as they sought to head off Arizona’s stay application (11A1189).
