In the event the circuit judge, in any such case, is of the opinion that such action will expedite hearing and determination of the contest, the circuit judge may appoint the State Board of Elections and refer the case to it to recount the ballots, to take testimony and other evidence, to examine records and equipment, to make a record of all objections to be heard by the circuit court that may be made to the election returns or to any of them or to any ballots cast or counted and to take all necessary steps and do all necessary things to determine the true and correct result of the election and to make a report thereof to the court. The State Board of Elections shall have authority to count the ballots or cause the same to be counted under its supervision and direction, to conduct such hearing or hearings as may be necessary and proper, to apply to the circuit court in the manner provided by law for the issuance of subpoenas or for any other appropriate order or orders to compel the attendance of witnesses, and to take such steps and perform such duties and acts in connection with the conduct of any such hearing or hearings as may be necessary. The State Board of Elections may, with the approval of the court, employ such assistants as may be necessary and proper to provide for counting the ballots, examining any records and equipment and taking all necessary steps and doing all necessary things to determine the true and correct result of the election under the direction and supervision of the State Board of Elections. The State Board of Elections shall receive such compensation for its services and such allowances for the services of its assistants and for reimbursement of expenses incurred by it as shall be approved by the circuit court, and such compensation and allowances when approved by the circuit court may be taxed as costs in such cause.
