S.D. Codified Laws § 40-2-6

The board of directors of a humane society incorporated pursuant to § 40-2-1 may appoint society members to act as animal control officers. The appointment shall be in writing. The appointment is effective in a particular county only if an appointee obtains written authorization from a circuit court judge having jurisdiction in the county in which the appointee seeks to enforce this chapter or chapter 40-1. To obtain judicial authorization, an appointee seeking judicial authorization shall provide evidence satisfactory to the judge that the appointee has experience, education, or training that has prepared the appointee to assume the powers granted to animal control officers pursuant to § 40-2-7. The board of directors shall review appointments every three years and may revoke an appointment at any time by filing a certified revocation with the circuit court that approved the appointment. Any authorization may not exceed three years or trustee termination, whichever occurs first.
