ST. PAUL, Minn. - Groups opposed to a proposed constitutional amendment to require photo IDs for voting are arguing to Minnesota's highest court that allowing the ballot question to move forward would set up a "voter beware" choice.

Lawyers representing the League of Women Voters, Common Cause and other groups filed a brief Monday. It contends that backers deliberately withheld details about how elections will be conducted if voters adopt the photo ID requirement this November.

The opponents want the Supreme Court to strike the measure from the ballot. They say there are too many vagaries about which IDs are deemed adequate, how provisional ballots will be handled and what happens to people who don't vote in person.

The GOP-led Legislature's attorneys argue that courts usually give lawmakers latitude in crafting ballot questions.
