The New Hampshire attorney general's office says the state and two advocacy groups have failed to reach a settlement in a case challenging a new law that blocks out-of-state students from voting unless they establish legal residency in the state.
A superior court judge set a deadline of Friday for the state and the New Hampshire chapters of the League of Women Voters and the American Civil Liberties Union to reach a compromise.
Assistant Attorney General Richard Head says settling constitutional challenges is no easy task. He says the office will await the court's ruling.
Representatives of the advocacy groups did not immediately return calls seeking comment.
The law — which passed over Gov. John Lynch's veto — would require those registering to declare New Hampshire their legal domicile.
