S.D. Codified Laws § 27A-15-4
Application for admission of a minor to an inpatient psychiatric facility may be made by a guardian or legal custodian of the person of the minor upon the recommendation for such application by a qualified mental health professional. The provisions of this chapter, including § 27A-15-5, apply to the admission of the minor. The rights and obligations specified for the parent and the minor in this chapter shall be equally applicable to and enforceable by or against the guardian and the minor. Emergency admission of the minor shall be governed by the provisions for involuntary commitment as set forth in this chapter and in this title. Nothing in this section precludes the secretary of the Department of Corrections or the court from placing a child in an inpatient psychiatric facility upon the recommendation of a qualified mental health professional if it is determined the minor meets the applicable criteria.
