S.D. Codified Laws § 36-1C-2
Any person claiming that a licensee or an applicant for a license under title 36 has engaged in or is engaging in conduct constituting grounds for disciplinary action, as enumerated in the laws or rules of the agency, may file with the agency a written complaint. The agency shall require the complaining party to file a complaint stating the name of the applicant or licensee against whom the complaint is made and setting out, in full detail, the conduct that is alleged to be in violation and may prescribe the form on which a written complaint is made.
The administrator shall request the complainant provide additional information if the complaint does not state a claim within the jurisdiction of the agency.
Failure of the complainant to comply with this section is basis for the administrator to reject the complaint without further action.
