S.D. Codified Laws § 23A-46-12
The director of the medical facility responsible for administering the regimen imposed on a person conditionally discharged under § 23A-46-11 shall notify the prosecuting attorney and the court having jurisdiction over the person of any failure of the person to comply with the regimen. On such notice, or upon other probable cause to believe that the person has failed to comply with the prescribed regimen of medical, psychiatric, or psychological care or treatment, the person may be arrested and, upon arrest, shall be taken without unnecessary delay before the court having jurisdiction over him. The court shall, after a hearing, determine whether the person should be remanded to a suitable facility on the ground that, in light of his failure to comply with a prescribed regimen of medical, psychiatric, or psychological care or treatment, his continued release would create a substantial risk of bodily injury to another person or serious damage to property of another.
