Any person (1) claiming to have been aggrieved by any ruling of any election official in connection with a referendum, (2) claiming that there has been a mistake in the count of votes cast for a referendum, or (3) claiming to be aggrieved by a violation of any provision of § 9-355, 9-357 to 9-361, inclusive, 9-364, 9-364a or 9-365 in the casting of absentee ballots at a referendum, may bring a complaint to any judge of the Superior Court for relief from such ruling, mistake or violation. In any action brought pursuant to the provisions of this section, the complainant shall send a copy of the complaint by first class mail, or deliver a copy of the complaint by hand, to the State Elections Enforcement Commission. If such complaint is made prior to such referendum, such judge shall proceed expeditiously to render judgment on the complaint and shall cause notice of the hearing to be given to the Secretary of the State and the State Elections Enforcement Commission. If such complaint is made subsequent to such referendum, it shall be brought within thirty days after such referendum to any judge of the Superior Court, in which the person shall set out the claimed errors of the election official, the claimed errors in the count or the claimed violations of said sections. Such judge shall forthwith order a hearing to be held upon such complaint, upon a day not more than five or less than three days from the making of such order, and shall cause notice of not less than three or more than five days to be given to any person who may be affected by the decision upon such hearing, to such election official, the Secretary of the State, the State Elections Enforcement Commission and to any other party or parties whom such judge deems proper parties to the hearing, of the time and place for the hearing upon such complaint. Such judge shall, on the day fixed for such hearing and without unnecessary delay, proceed to hear the parties. If sufficient reason is shown, such judge may order any voting tabulators to be unlocked or any ballot boxes to be opened and a recount of the votes cast, including absentee ballots, to be made. Such judge shall, if such judge finds any error in the rulings of the election official or any mistake in the count of the votes, certify the result of such judge’s finding or decision to the Secretary of the State before the tenth day succeeding the conclusion of the hearing. Such judge may order a new referendum or a change in the existing referendum schedule. Such certificate of such judge’s finding or decision shall be final and conclusive upon all questions relating to errors in the ruling of such election officials, to the correctness of such count, and, for the purposes of this section only, such claimed violations, and shall operate to correct the returns of the moderators or presiding officers, so as to conform to such finding or decision, except that this section shall not affect the right of appeal to the Supreme Court and it shall not prevent such judge from reserving such questions of law for the advice of the Supreme Court as provided in § 9-325. Such judge may, if necessary, issue a writ of mandamus, requiring the adverse party and those under such judge to deliver to the complainant the appurtenances of such office, and shall cause such judge’s finding and decree to be entered on the records of the Superior Court in the proper judicial district.
