Iowa Code § 50.46: Special elections — canvass and certificate.

When a special election has been held to fill a vacancy, pursuant to section 69.14, the board of county canvassers shall meet no earlier than 1:00 p.m. on the second day after the election, and canvass the votes cast at the election. If the second day after the election is a public holiday, section 4.1, subsection 34, controls. The commissioner, as soon as the canvass is completed, shall transmit to the state commissioner an abstract of the votes so canvassed, and the state board, within five days after receiving such abstracts, shall canvass the tally lists. A certificate of election shall be issued by the county or state board of canvassers, as in other cases. All the provisions regulating elections, obtaining tally lists, and canvass of votes at general elections, except as to time, shall apply to special elections.
