If there is a tie vote for any office, the legislative body or, in its stead, the municipal clerk shall within seven days warn a runoff election to be held not less than 15 days nor more than 22 days after the warning. The only candidates in the runoff election shall be those who were tied in the original election. However, if one of the candidates that are tied withdraws his or her candidacy within five days after the election, the town clerk shall certify the other tied candidate as the winner, and there shall be no runoff election. (Added 2013, No. 161 (Adj. Sess.), § 55.)
