The judges of election shall make the tally sheet and certificate of results in triplicate. If, however, the number of established political parties, as defined in Section 10-2, exceeds 2, one additional copy shall be made for each established political party in excess of 2. One list of voters, or other proper return with such certificate written thereon, and accompanying tally sheet footed up so as to show the correct number of votes cast for each person voted for, shall be carefully enveloped and sealed up by the judges of election, 2 of whom (one from each of the 2 major political parties) shall immediately deliver same to the county clerk, or his deputy, at the office of the county clerk, or to an officially designated receiving station established by the county clerk where a duly authorized representative of the county clerk shall receive said envelopes for immediate transmission to the office of county clerk, who shall safely keep them. The other certificates of results and accompanying tally sheet shall be carefully enveloped and sealed up and duly directed, respectively, to the chair of the county central committee of each then existing established political party, and by another of the judges of election deposited immediately in the nearest United States letter deposit. However, if any county chair notifies the county clerk not later than 10 days before the election of his desire to receive the envelope addressed to him at the point and at the time same are delivered to the county clerk, his deputy or receiving station designee the envelopes shall be delivered to such county chair or his designee immediately upon receipt thereof by the county clerk, his deputy or his receiving station designee. The person or persons so designated by a county chair shall sign an official receipt acknowledging receipt of said envelopes. The poll book and tally list filed with the county clerk shall be kept one year, and certified copies thereof shall be evidence in all courts, proceedings and election contests. Before the returns are sealed up, as aforesaid, the judges shall compare the tally papers, footings and certificates and see that they are correct and duplicates of each other, and certify to the correctness of the same.
At the consolidated election, the judges of election shall make a tally sheet and certificate of results for each political subdivision for which candidates or public questions are on the ballot at such election, and shall sign, seal in a marked envelope and deliver them to the county clerk with the other certificates of results herein required. Such tally sheets and certificates of results may be duplicates of the tally sheet and certificate of results otherwise required by this Section, showing all votes for all candidates and public questions voted for or upon in the precinct, or may be on separate forms prepared by the election authority and showing only those votes cast for candidates and public questions of each such political subdivision.
Within 2 days of delivery of complete returns of the consolidated election, the county clerk shall transmit an original, sealed tally sheet and certificate of results from each precinct in his jurisdiction in which candidates or public questions of a political subdivision were on the ballot to the local election official of such political subdivision. Each local election official, within 24 hours of receipt of all of the tally sheets and certificates of results for all precincts in which candidates or public questions of his political subdivision were on the ballot, shall transmit such sealed tally sheets and certificates of results to the canvassing board for that political subdivision.
In the case of referenda for the formation of a political subdivision, the tally sheets and certificates of results shall be transmitted by the county clerk to the circuit court that ordered the proposition submitted or to the officials designated by the court to conduct the canvass of votes. In the case of school referenda for which a regional superintendent of schools is responsible for the canvass of votes, the county clerk shall transmit the tally sheets and certificates of results to the regional superintendent of schools.
Where voting machines or electronic voting systems are used, the provisions of this section may be modified as required or authorized by Article 24 or Article 24A, whichever is applicable.
Only judges appointed under the provisions of subsection (a) of Section 13-4 or subsection (b) of Section 14-1 may make any delivery required by this Section from judges of election to a county clerk, or his or her deputy, at the office of the county clerk or to a county clerk's duly authorized representative at the county clerk's officially designated receiving station.
