A federal appeals court lifted a block on an Indiana law barring student identification cards from being used for voting in elections, as early voting in the state’s primaries nears its third week.

A three-judge panel on the U.S. Court of Appeals for the 7th Circuit granted a stay pending appeal of a lower court’s ruling last week that had found the state’s ban on using student IDs as voter IDs unconstitutional under the First and 14th amendments. The brief order means the state may enforce its law limiting valid forms of voter ID, with the appeals court panel saying a full “reasoned decision” explaining its ruling will be published on the docket in the coming days.
