Upon receipt of the certificates of the election authorities showing the results of the sample signature verification, the Board shall:
If such statewide projection establishes a total number of valid petition signatures not greater than 95.0% of the minimum number of signatures required to qualify the proposed statewide advisory public question for the ballot, the petition shall be presumed invalid; provided that, prior to the last day for ballot certification for the general election, the Board shall conduct a hearing for the purpose of allowing the proponents to present competent evidence or an additional sample to rebut the presumption of invalidity. At the conclusion of such hearing, and after the resolution of any specific objection filed pursuant to Section 10-8 of this Code, the Board shall issue a final order declaring the petition to be valid or invalid and shall, in accordance with its order, certify or not certify the proposition for the ballot.
If such statewide projection establishes a total number of valid petition signatures greater than 95.0% of the minimum number of signatures required to qualify the proposed Constitutional amendment or statewide advisory public question for the ballot, the results of the sample shall be considered inconclusive and, if no specific objections to the petition are filed pursuant to Section 10-8 of this Code, the Board shall issue a final order declaring the petition to be valid and shall certify the proposition for the ballot.
In either event, the Board shall append to its final order the detailed results of the sample from each election jurisdiction which shall include: (a) specific page and line numbers of signatures actually verified or determined to be invalid by the respective election authorities, and (b) the calculations and projections performed by the Board for each election jurisdiction.
