The Secretary shall investigate such complaint and, if he finds probable cause to believe that a violation of this subchapter has occurred and has not been remedied, he shall, within sixty days after the filing of such complaint, bring a civil action against the labor organization as an entity in the district court of the United States in which such labor organization maintains its principal office to set aside the invalid election, if any, and to direct the conduct of an election or hearing and vote upon the removal of officers under the supervision of the Secretary and in accordance with the provisions of this subchapter and such rules and regulations as the Secretary may prescribe. The court shall have power to take such action as it deems proper to preserve the assets of the labor organization.
An order directing an election, dismissing a complaint, or designating elected officers of a labor organization shall be appealable in the same manner as the final judgment in a civil action, but an order directing an election shall not be stayed pending appeal.
