FILE - In an Aug. 10, 2012 file photo, worshipers leave the Islamic Center of Murfreesboro after midday prayers in Murfreesboro, Tenn. Opponents of the new Tennessee mosque want a federal judge to give them a say in a religious discrimination case involving the building. For two years the group fought to shut down construction of the Islamic Center of Murfreesboro in state court. On Thursday, ,Aug. 23, 2012, the building received its final certificate of occupancy and it is unclear what the mosque opponents could achieve at this point if they were allowed to intervene in the federal case.
