SDCL § 13-7-7: Withdrawal or death of candidate--Procedure--Effect.

Any candidate who has filed a nominating petition pursuant to § 13-7-6 may withdraw from the nomination by making a written request under oath. The candidate shall file the request with the school district's business manager. The business manager may not print the name of a candidate if the candidate withdraws or dies before five p.m. local time on the first Thursday after the deadline for filing a nominating petition.

If the death or withdrawal of a candidate at any time before the withdrawal deadline results in the number of nominating petitions filed for the vacant position to be equal to or less than the number of vacancies, the contest may not be placed on the ballot, and the business manager shall issue a certificate of election to the unopposed candidate. If that contest is the only contest to be voted upon, the business manager must cancel the election.
