S.D. Codified Laws § 21-66-4

The plaintiff shall make available to each party any trust claims material for each asbestos trust claim that has been filed by the plaintiff or by anyone on the plaintiff's behalf against an asbestos trust, including any asbestos-related disease. The plaintiff shall supplement the information and material provided pursuant to this section within ninety days after the plaintiff files an additional asbestos trust claim, supplements an existing asbestos trust claim, or receives additional information or material related to any claim or potential claim against an asbestos trust. Failure by the plaintiff to make available to all parties any trust claims material required under this section constitutes grounds for the court to extend the trial date in an asbestos action.
