(10 ILCS 5/17-9) (from Ch. 46, par. 17-9)
    Sec. 17-9. Any person desiring to vote shall give his name and, if required to do so, his residence to the judges of election, one of whom shall thereupon announce the same in a loud and distinct tone of voice, clear, and audible; the judges of elections shall check each application for ballot against the list of voters registered in that precinct to whom grace period, vote by mail, or early ballots have been issued for that election, which shall be provided by the election authority and which list shall be available for inspection by pollwatchers. A voter applying to vote in the precinct on election day whose name appears on the list as having been issued a grace period, vote by mail, or early ballot shall not be permitted to vote in the precinct, except that a voter to whom a vote by mail ballot was issued may vote in the precinct if the voter submits to the election judges that vote by mail ballot for cancellation. If the voter is unable to submit the vote by mail ballot, it shall be sufficient for the voter to submit to the election judges (i) a portion of the vote by mail ballot if the vote by mail ballot was torn or mutilated or (ii) an affidavit executed before the election judges specifying that (A) the voter never received a vote by mail ballot or (B) the voter completed and returned a vote by mail ballot and was informed that the election authority did not receive that vote by mail ballot. All applicable provisions of Articles 4, 5 or 6 shall be complied with and if such name is found on the register of voters by the officer having charge thereof, he shall likewise repeat said name, and the voter shall be allowed to enter within the proximity of the voting booths, as above provided. One of the judges shall give the voter one, and only one of each ballot to be voted at the election, on the back of which ballots such judge shall indorse his initials in such manner that they may be seen when each such ballot is properly folded, and the voter's name shall be immediately checked on the register list. In those election jurisdictions where perforated ballot cards are utilized of the type on which write-in votes can be cast above the perforation, the election authority shall provide a space both above and below the perforation for the judge's initials, and the judge shall endorse his or her initials in both spaces. Whenever a proposal for a constitutional amendment or for the calling of a constitutional convention is to be voted upon at the election, the separate blue ballot or ballots pertaining thereto shall, when being handed to the voter, be placed on top of the other ballots to be voted at the election in such manner that the legend appearing on the back thereof, as prescribed in Section 16-6 of this Act, shall be plainly visible to the voter. At all elections, when a registry may be required, if the name of any person so desiring to vote at such election is not found on the register of voters, he or she shall not receive a ballot until he or she shall have complied with the law prescribing the manner and conditions of voting by unregistered voters. If any person desiring to vote at any election shall be challenged, he or she shall not receive a ballot until he or she shall have established his right to vote in the manner provided hereinafter; and if he or she shall be challenged after he has received his ballot, he shall not be permitted to vote until he or she has fully complied with such requirements of the law upon being challenged. Besides the election officer, not more than 2 voters in excess of the whole number of voting booths provided shall be allowed within the proximity of the voting booths at one time. The provisions of this Act, so far as they require the registration of voters as a condition to their being allowed to vote shall not apply to persons otherwise entitled to vote, who are, at the time of the election, or at any time within 60 days prior to such election have been engaged in the military or naval service of the United States, and who appear personally at the polling place on election day and produce to the judges of election satisfactory evidence thereof, but such persons, if otherwise qualified to vote, shall be permitted to vote at such election without previous registration.
