LINCOLN, Neb. (AP) — A federal judge has sent a lawsuit challenging Nebraska’s practice of denying driver’s licenses for some immigrants back to Nebraska state court, saying it doesn’t raise a definitive federal issue.

Chief U.S. District Judge Laurie Smith Camp on Friday rejected the contention by Nebraska attorneys that federal court was best venue for the lawsuit.

The American Civil Liberties Union filed the lawsuit last year in Lancaster County District Court on behalf of four Omaha residents. The lawsuit says Nebraska officials violated state law by refusing to issue driver’s licenses to participants in President Barack Obama’s Deferred Action for Childhood Arrivals program. The program allows people brought to the U.S. illegally as children to work in the country, and protects them from deportation.
