"The U.S. Supreme Court on Monday declined to review the legality of new Republican-backed voting restrictions in North Carolina that were part of a law opponents argued was aimed at making it harder for voters who tend to favor Democrats to cast ballots. The court rejected the state's appeal of an October decision by the Richmond, Virginia-based 4th U.S. Circuit Court of Appeals that found that parts of the 2013 law should be provisionally blocked while litigation continues. The law put in place a requirement that voters show certain forms of photo identification in order to cast a ballot as well as other provisions. At issue in the current case are the sections of the law that barred same-day voter registration and provisional voting for voters casting ballots outside their normal precincts."
