The US Court of Appeals for the Seventh Circuit on Thursday upheld an Indiana law requiring voters to show photo identification before casting a ballot. In its ruling, the court upheld a lower court decision that the law does not put an undue burden on the right to vote and therefore does not violate the US Constitution. The Indiana Democratic Party and the American Civil Liberties Union of Indiana had appealed the district court's decision, but during oral arguments Judge Richard Posner, who wrote the appeals court ruling, was skeptical of the plaintiffs' contention that the law would prevent voters from casting ballots.

The US Supreme Court issued a per curiam opinion last October ruling that Arizona could enforce its voter ID law, which requires voters to show government-issued ID cards at the polls. Similar voter ID laws have been upheld in Georgia and Pennsylvania, though the Missouri Supreme Court struck down a law last year requiring voters to show ID cards at the polls. A lawsuit over Ohio's voter ID legislation ended just before last November's mid-term election in a settlement requiring future Ohio absentee voters to show proof of ID when applying for absentee ballots, but allowing absentee ballots already obtained without ID to be counted.
