Section 15-6-37(c) - Failure to disclose-False or misleading disclosure-Refusal to admit(1) A party that without substantial justification fails to disclose information required by subdivision 15-6-26(e)(1), or to amend a prior response to discovery as required by subdivision 15-6-26(e)(2), is not, unless such failure is harmless, permitted to use as evidence at a trial, at a hearing, or on a motion any witness or information not so disclosed. In addition to or in lieu of this sanction, the court, on motion and after affording an opportunity to be heard, may impose other appropriate sanctions. In addition to requiring payment of reasonable expenses, including attorneys' fees, caused by the failure, these sanctions may include any of the actions authorized under subdivisions 15-6-37(b)(2)(A), (2)(B), and (2)(C) and may include informing the jury of the failure to make the disclosure.(2) If a party fails to admit the genuineness of any document or the truth of any matter as requested under § 15-6-36, and if the party requesting the admissions thereafter proves the genuineness of the document or the truth of the matter, the requesting party may apply to the court for an order requiring the other party to pay the reasonable expenses incurred in making that proof, including reasonable attorneys' fees. The court shall make the order unless it finds that:(A) The request was held objectionable pursuant to § 15-6-36(a); or(B) The admission sought was of no substantial importance; or(C) The party failing to admit had reasonable ground to believe that the party might prevail on the matter; or(D) There was other good reason for the failure to admit.SDC 1939 & Supp 1960, § 36.0606; SD RCP, Rule 37 (c), as adopted by Sup.
