S.D. Codified Laws § 34-23A-23
In every civil or criminal proceeding or action brought pursuant to this chapter, the court shall rule whether the anonymity of any female upon whom an abortion is performed or attempted shall be preserved from public disclosure if she does not give her consent to such disclosure. The court, upon motion or sua sponte, shall make such a ruling and, upon determining that her anonymity should be preserved, shall issue orders to the parties, witnesses, and counsel, and shall direct the sealing of the record and exclusion of individuals from courtrooms or hearing rooms, to the extent necessary to safeguard her identity from public disclosure. Each such order shall be accompanied by specific written findings explaining why the anonymity of the female should be preserved from public disclosure, why the order is essential to that end, how the order is narrowly tailored to serve that interest, and why no reasonable less restrictive alternative exists. In the absence of written consent of the female upon whom an abortion has been performed or attempted, anyone, other than a public official, who brings an action pursuant to this chapter shall do so under a pseudonym. This section may not be construed to conceal the identity of the plaintiff or of witnesses from the defendant.
