When the canvass of the ballots has been completed, and the tally judges have announced to the judges the total number of votes received by each candidate, each of the judges of the election in turn shall then proclaim, in a loud voice, the total number of votes received by each of the persons voted for in such precinct, and the office for which he is designated, and the number of votes for and the number of votes against any proposition which shall have been submitted to a vote of the people. Such proclamation shall be prima facie evidence of the result of the canvass of such ballots.
Immediately after making such proclamation the judges shall designate one of their number to go to the nearest telephone and report to the office of the board of election commissioners the result announced in such proclamation. The board of election commissioners shall keep its office open after the close of the polls on the day of any election until it has received from each precinct in the county the report above provided for. Immediately upon receiving such report the board of election commissioners shall cause the same to be posted in a public place in its office for inspection by the public. Immediately after making such report such judge shall return to the polling place and the judges shall proceed with their duties prescribed in this Code.
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.
