S.D. Codified Laws § 27A-11A-19
No person who is under an order of involuntary commitment may be transferred to a more restrictive treatment facility without, prior to the transfer, a hearing before the board of mental illness which committed the person. A petition for transfer shall be filed with the chair of the board. The person shall have at least five days notice of the hearing and has the right to be represented by an attorney. At the time of the notice, the board chair shall appoint an attorney to represent the person if that person has not retained counsel.
If transfer to the more restrictive treatment facility is necessary to prevent the immediate danger of physical harm to the person or others, the transfer may be authorized by the chair of the board pending the hearing. The hearing shall be held within five days of the initiation of the transfer, within six days if there is a Saturday, Sunday, or holiday within that time period, or within seven days if there is a Saturday, Sunday, and holiday within that time period.
Upon completion of the hearing, if the board finds by clear and convincing evidence supported by written findings of fact and conclusions of law that the proposed transfer meets the criteria in § 27A-10-9.1, the board may authorize the transfer pursuant to the initial commitment order. The transfer hearing does not substitute for the review hearings to which the person would otherwise be entitled under §§ 27A-10-14 and 27A-10-15.
The county board of mental illness authorizing a transfer under this section may authorize the sheriff of the county from which the person was initially committed to transfer the person at the expense of the county. The sheriff shall be paid no per diem but only mileage as allowed by law.
