S.D. Codified Laws § 51A-15-10

A bank may, at any time prior to the director's cancellation of its charter, revoke its intention to voluntarily liquidate under § 51A-15-1, if it receives approval of its action upon an affirmative vote of at least two-thirds of the voting shares of the bank. Written evidence of its intentions delivered to the director prior to cancellation are considered an effective revocation.
