 (from Ch. 46, par. 10-6.2)Sec. 10-6.2.   The State Board of Elections, the election authority or  the local election official with whom petitions for nomination are filed  pursuant to this Article 10 shall specify the place where filings shall  be made and upon receipt shall endorse thereon the day and the hour at  which each petition was filed.  Except as provided by Article 9 of The  School Code, all petitions filed by persons waiting  in line as of 8:00 a.m. on the first day for filing, or as of the normal  opening hour of the office involved on such day, shall be deemed filed  as of 8:00 a.m. or the normal opening hour, as the case may be.  Petitions filed by mail and received after midnight of the first day for  filing and in the first mail delivery or pickup of that day shall be  deemed filed as of 8:00 a.m. of that day or as of the normal opening  hour of such day, as the case may be.  All petitions received thereafter  shall be deemed filed in the order of actual receipt.  However, 2 or more petitions filed within the last hour of the filing deadline shall be deemed filed simultaneously. Where 2 or more  petitions are received simultaneously, the State Board of Elections, the  election authority or the local election official with whom such  petitions are filed shall break ties and determine the order of filing  by means of a lottery or other fair and impartial method of random  selection approved by the State Board of Elections.  Such lottery shall  be conducted within 9 days following the last day for petition filing and shall  be open to the public. Seven days written notice of the time and place of  conducting such random selection shall be given, by the State Board of  Elections, the election authority, or local election official, to the Chair   of each political party, and to each organization of citizens within the  election jurisdiction which was entitled, under this Code, at the next  preceding election, to have pollwatchers present on the day of election. The  State Board of Elections, the election authority or local election official  shall post in a conspicuous, open and public place, at the entrance of the  office, notice of the time and place of such lottery. The State Board of  Elections shall adopt rules and regulations governing the procedures for  the conduct of such lottery. All candidates shall be  certified in the order in which their petitions have been filed and in the  manner prescribed by Section 10-14 and 10-15 of this Article.  Where  candidates have filed simultaneously, they shall be certified in the order  determined by lot and prior to candidates who filed for the same office or  offices at a later time.  Certificates of nomination filed within the  period prescribed in Section 10-6(2) for candidates nominated by caucus for  township or municipal offices shall be subject to the ballot placement  lottery for established political parties prescribed in Section 7-60 of  this Code.If multiple sets of nomination papers are filed for a candidate to  the same office, the State Board of Elections, appropriate election  authority or local election official where the petitions are filed shall  within 2 business days notify the candidate of his or her multiple petition  filings and that the candidate has 3 business days after receipt of the notice  to notify the State Board of Elections, appropriate election authority or local  election official that he or she may cancel prior sets of petitions. If the  candidate notifies the State Board of Elections, appropriate election authority  or local election official, the last set of petitions filed shall be the only  petitions to be considered valid by the State Board of Elections, election  authority or local election official.  If the candidate fails to notify the  State Board of Elections, appropriate election authority or local election  official then only the first set of petitions filed shall be valid and all  subsequent petitions shall be void.
