A federal judge forcefully slapped down North Dakota’s efforts to fight his ruling that loosened the state’s voter identification law Monday.

U.S. District Judge Daniel Hovland denied the state’s request to delay part of that ruling amid an appeal. The request focused on the April 3 order preventing the state from requiring that IDs include a “current residential street address,” which Native American communities often lack.

Attorneys for the state warned Hovland’s order could allow residents of other states to vote here, but the judge said they have “raised a litany of embellished concerns” and haven’t shown “any evidence of voter fraud in the past or present.” He suggested both sides “sit down for one day and create workable and reasonable solutions,” possibly with the help of a mediator.
