U.S. District Judge Julie Robinson on Monday ruled a Kansas law that requires new voters to prove citizenship is unconstitutional and ordered Kansas Secretary of State Kris Kobach to return to school as punishment for repeated violations of court rules. Her 118-page ruling sides with the American Civil Liberties Union in a two-year legal battle over the law’s burden and effect on elections. She provided a damning assessment of Kobach’s witnesses, calling their evidence flawed, invalid, biased, irrelevant, unreliable and untrustworthy.
