S.D. Codified Laws § 15-6-37(d)
If a party or an officer, director, or managing agent of a party or a person designated under subdivision 15-6-30(b)(6) or § 15-6-31(a) to testify on behalf of a party fails (1) to appear before the officer who is to take the deposition, after being served with a proper notice, or (2) to serve answers or objections to interrogatories submitted under § 15-6-33, after proper service of the interrogatories, or (3) to serve a written response to a request for inspection submitted under § 15-6-34, after proper service of the request, the court in which the action is pending on motion may make such orders in regard to the failure as are just, and among others it may take any action authorized under subdivisions 15-6-37(b)(2)(A), (2)(B), and (2)(C). In lieu of any order or in addition thereto, the court shall require the party failing to act or the attorney advising him or both to pay the reasonable expenses, including attorney's fees, caused by the failure, unless the court finds that the failure was substantially justified or that other circumstances make an award of expenses unjust.
The failure to act described in this subdivision may not be excused on the ground that the discovery sought is objectionable unless the party failing to act has applied for a protective order as provided by § 15-6-26(c).
