S.D. Codified Laws § 10-50-67

In addition to any other remedy provided by law, any person may bring an action for appropriate injunctive or other equitable relief for a violation of § 10-50-65; actual damages, if any, from the distributor, wholesaler, or other violator sustained by reason of the violation; and, as determined by the court, interest on the damages from the date of the complaint, taxable costs, and reasonable attorney's fees. If the trier of fact finds that the violation is flagrant, it may increase recovery to an amount not in excess of three times the actual damages sustained by reason of the violation.
