S.D. Codified Laws § 27A-10-9.1
Upon completion of the hearing provided in § 27A-10-8, the board of mental illness may order the involuntary commitment of the person for an initial period not to exceed ninety days if a majority of the board finds by clear and convincing evidence, supported by written findings of fact and conclusions of law, that:
The board may commit the person to the Human Services Center or a veterans' administration hospital. The board may also commit the person to a private facility or an outpatient treatment program, if that facility or program agrees to accept the commitment and if the commitment will not result in liability to any county for the cost of treating such person.
If the above findings are not made, the board shall order that the person be released. Following such release, the referring county shall provide the person with transportation to the county where the person was taken into custody if the person chooses. The county ultimately shown to be the county of residence shall reimburse the referring county for any transportation costs. However, the provisions of chapter 28-14 do not apply. If the board orders the involuntary commitment of the person, the board shall immediately notify the person and the person's attorney of the right to appeal pursuant to § 27A-11A-25.
