SEATTLE (AP) — A federal magistrate says he expects to rule early next week on whether to release a Mexican man who was arrested near Seattle despite his participation in a program to protect those brought to the U.S. illegally as children.

Daniel Ramirez Medina is asking a Seattle court to find that his arrest Feb. 10 violated his constitutional rights.

U.S. Magistrate Judge James P. Donohue said at a hearing Wednesday he wouldn't immediately rule because the Justice Department improperly made a new argument in a brief filed Tuesday, leaving Ramirez's attorneys little chance to respond.
