The precinct return printed by the automatic tabulating equipment shall include the number of ballots cast and votes cast for each candidate and proposition 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 write-in votes, the total number of 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 with respect to the total number of votes cast in any precinct, shall have the ballots for such precinct retabulated to correct the return. The procedures for retabulation 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 except for election contests and discovery recounts. In those election jurisdictions that utilize in-precinct counting equipment, the certificate of results, which has been prepared 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 which has been affixed to such certificate of results, the ballots for such precinct shall be retabulated to correct the return. As an additional part of this check prior to the proclamation, in those jurisdictions where in-precinct counting equipment is utilized, the election authority shall retabulate the total number of votes cast 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 retabulated shall be selected after election day on a random basis by the State Board of Elections, so that every precinct in the election jurisdiction and every voting device used in early voting 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 which are to be retabulated. The State central committee chair of each established political party shall be given prior written notice of the time and place of such random selection procedure and may be represented at such procedure. Such retabulation shall consist of counting the ballot cards which were originally counted and shall not involve any determination as to which ballot cards were, in fact, properly counted. The ballots from the precincts selected for such retabulation shall remain at all times under the custody and control of the election authority and shall be transported and retabulated by the designated staff of the election authority.
     As part of such retabulation, the election authority shall test the computer program in the selected precincts and on the selected early voting devices. Such test shall be conducted by processing a preaudited group of ballots so punched so as to record a predetermined number of valid votes for each candidate and on each public question, and shall include for each office one or more ballots which have votes in excess of the number allowed by law in order to test the ability of the equipment to reject such votes. If any error is detected, the cause therefor shall be ascertained and corrected and an errorless count shall be made prior to the official canvass and proclamation of election results.
     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 such retabulation and may be represented at such retabulation.
     The results of this retabulation 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 Act. Upon completion of the retabulation, the election authority shall print a comparison of the results of the retabulation with the original precinct return printed by the automatic tabulating equipment. Such comparison shall be done for each precinct and for each early voting device selected for testing and for each office voted upon within that precinct or on that voting device, and the comparisons shall be open to the public.
