(10 ILCS 5/24C-15)
    Sec. 24C-15. Official return of precinct; check of totals; audit. The precinct return printed by the Direct Recording Electronic Voting System tabulating equipment shall include the number of ballots cast and votes cast for each candidate and public question and shall constitute the official return of each precinct. In addition to the precinct return, the election authority shall provide the number of applications for ballots in each precinct, the total number of ballots and vote by mail ballots counted in each precinct for each political subdivision and district and the number of registered voters in each precinct. However, the election authority shall check the totals shown by the precinct return and, if there is an obvious discrepancy regarding the total number of votes cast in any precinct, shall have the ballots for that precinct audited to correct the return. The procedures for this audit shall apply prior to and after the proclamation is completed; however, after the proclamation of results, the election authority must obtain a court order to unseal voted ballots or voting devices except for election contests and discovery recounts. The certificate of results, which has been prepared and signed by the judges of election after the ballots have been tabulated, shall be the document used for the canvass of votes for such precinct. Whenever a discrepancy exists during the canvass of votes between the unofficial results and the certificate of results, or whenever a discrepancy exists during the canvass of votes between the certificate of results and the set of totals reflected on the certificate of results, the ballots for that precinct shall be audited to correct the return.
    Prior to the proclamation, the election authority shall test the voting devices and equipment in 5% of the precincts within the election jurisdiction, as well as 5% of the voting devices used in early voting. The precincts and the voting devices to be tested shall be selected after election day on a random basis by the State Board of Elections, so that every precinct and every device used in early voting in the election jurisdiction has an equal mathematical chance of being selected. The State Board of Elections shall design a standard and scientific random method of selecting the precincts and voting devices that are to be tested. The State central committee chair of each established political party shall be given prior written notice of the time and place of the random selection procedure and may be represented at the procedure.
    The test shall be conducted by counting the votes marked on the permanent paper record of each ballot cast in the tested precinct printed by the voting system at the time that each ballot was cast and comparing the results of this count with the results shown by the certificate of results prepared by the Direct Recording Electronic Voting System in the test precinct. The election authority shall test count these votes either by hand or by using an automatic tabulating device other than a Direct Recording Electronic voting device that has been approved by the State Board of Elections for that purpose and tested before use to ensure accuracy. The election authority shall print the results of each test count. If any error is detected, the cause shall be determined and corrected, and an errorless count shall be made prior to the official canvass and proclamation of election results. If an errorless count cannot be conducted and there continues to be difference in vote results between the certificate of results produced by the Direct Recording Electronic Voting System and the count of the permanent paper records or if an error was detected and corrected, the election authority shall immediately prepare and forward to the appropriate canvassing board a written report explaining the results of the test and any errors encountered and the report shall be made available for public inspection.
    The State Board of Elections, the State's Attorney and other appropriate law enforcement agencies, the county chair of each established political party and qualified civic organizations shall be given prior written notice of the time and place of the test and may be represented at the test.
    The results of this post-election test shall be treated in the same manner and have the same effect as the results of the discovery procedures set forth in Section 22-9.1 of this Code.
