S.D. Codified Laws § 51A-14-6
If the director, pursuant to § 51A-15-21, or if the commission deems it necessary that a state bank, national bank, or savings and loan association organized pursuant to 12 U.S.C. § 1464 as amended as of January 1, 1990, be merged, consolidated, or its assets purchased and its liabilities assumed in order to protect the depositors and the public from unsound practices, and another bank is willing to merge, consolidate, or purchase the assets and assume the liabilities of such financial institution, the commission may declare that such merger, consolidation, or purchase of assets and assumption of liabilities shall constitute an emergency takeover. The commission may waive any requirement, whether by law or by rule, relative to required application materials, thoroughness of the director's investigation, and length of time before the commission may act. Nothing in this section limits in any way the rights of shareholders of either financial institution to approve the transaction and the manner required by state or federal law.
