The provisions of Sections 10-8 through 10-10.1 relating to objections to nominating petitions, hearings on objections, and judicial review, shall apply to and govern, insofar as may be practicable, objections to petitions for the submission of questions of public policy required to be filed with local election officials and election authorities, and to petitions for proposed Constitutional amendments and statewide advisory public questions required to be filed with the State Board of Elections, except that objections to petitions for the submission of proposed Constitutional amendments and statewide advisory public questions may be filed within 42 business days after the petition is filed.
The electoral board to hear and pass on objections shall be the electoral board specified in Section 10-9 to have jurisdiction over objections to the nominating petitions of candidates for offices of the political subdivision in which the question of public policy is proposed to be submitted to the electors. The electoral board to hear and pass upon objections to petitions for proposed Constitutional amendments or statewide advisory public questions shall be the State Board of Elections.
Objections to petitions for the submission of public questions which are required by law to be filed with the circuit court shall be presented to and heard by the court with which such petitions are filed. In such cases, unless otherwise provided in the statute authorizing the public question, the court shall (1) set a hearing on the petition, (2) cause notice of such hearing to be published, as soon as possible after the filing of the petition but not later than 14 days after such filing and not less than 5 days before the hearing, in a newspaper of general circulation published in the political subdivision to which the public question relates and if there is no such newspaper, then in one newspaper published in the county and having a general circulation in the political subdivision, (3) conduct such hearing and entertain all objections as may be properly presented on or before such hearing date in the manner as provided in Article 10 for the conduct of proceedings before electoral boards, insofar as practicable, (4) conduct further hearings as necessary to a decision on the objections properly raised, and (5) enter a final order not later than 7 days after the initial hearing.
Where a statute authorizing a public question specifies judicial procedures for the determination of the validity of such petition, or for the determination by the court as to any findings required prior to ordering the proposition submitted to referendum, the procedures specified in that statute shall govern.
