SCOTUSBlog: “Arizona state officials asked the Supreme Court on Wednesday to allow election officials there to demand that all voters show proof of citizenship before they may register to vote   The divided en banc Ninth Circuit Court ruled in April that the citizenship proof requirement conflicts with a 1993 federal law passed to make it easier for individuals to sign up to vote.  The state took its plea for a delay of that ruling, for the duration of this year’s election season, to Justice Anthony M. Kennedy, who has the option of acting alone or referring the issue to his eight colleagues.  The application (11A1189) was filed in Arizona v. Gonzalez, et al.  The en banc Ninth Circuit, over three judges’ dissents, had denied a stay last week.”
