S.D. Codified Laws § 51A-1-12
It is unlawful for a bank to pay a fine or penalty imposed by law upon any other person or to reimburse directly or indirectly any person by whom such fine or penalty has been paid. Any bank that makes an unlawful payment is subject to the imposition of a civil fine by the director or commission not to exceed one hundred dollars for each unlawful payment. A bank may reimburse any person in settlement of its own liability or in connection with the acquisition of property against which the judgment is a lien, or as provided in § 51A-3-31. Any payments made by a bank in violation of this section are recoverable for the bank in an action instituted pursuant to the provisions of chapter 1-26 by the division from the person who benefited from such payment.
