The board shall complete the canvass not later than the twenty-first day after the day of the election. Eighty-one days after the day of the election, the canvass of election returns shall be deemed final, and no amendments to the canvass may be made after that date. The secretary of state may specify an earlier date upon which the canvass of election returns shall be deemed final, and after which amendments to the final canvass may not be made, if so required by federal law.
In connection with its investigation of any apparent or suspected error or defect in the election returns from a polling place, the board may cause subpoenas to be issued and served requiring the attendance before it of the election officials of that polling place, and it may examine them under oath regarding the manner in which the votes were cast and counted in that polling place, or the manner in which the returns were prepared and certified, or as to any other matters bearing upon the voting and the counting of the votes in that polling place at that election.
Finally, the board shall open the sealed container containing the ballots that were counted in the polling place at the election and count those ballots, during the official canvass, in the presence of all of the members of the board and any other persons who are entitled to witness the official canvass.
