Discovery methods. Parties may obtain discovery by one or more of the following methods: depositions upon oral examination or written questions; written interrogatories; production of documents or things or permission to enter upon land or other property, for inspection and other purposes; physical and mental examinations; and requests for admission. Unless the court orders otherwise under § 15-6-26(c), the frequency of use of these methods is not limited. Source: Supreme Court Rule 76-3, § 2. 15-6-26(b) . Scope of discovery. Unless otherwise limited by order of the court in accordance with these rules, the scope of discovery is as follows: (1) In general. Parties may obtain discovery regarding any matter, not privileged, which is relevant to the subject matter involved in the pending action, whether it relates to the claim or defense of the party seeking discovery or to the claim or defense of any other party, including the existence, description, nature, custody, condition and location of any books, documents, or other tangible things and the identity and location of persons having knowledge of any discoverable matter. It is not ground for objection that the information sought will be inadmissible at the trial if the information sought appears reasonably calculated to lead to the discovery of admissible evidence. The frequency or extent of use of the discovery methods set forth in § 15-6-26(a) shall be limited by the court if it determines that: (A)(i) the discovery sought is unreasonably cumulative or duplicative, or is obtainable from some other source that is more convenient, less burdensome, or less expensive; (ii) the party seeking discovery has had ample opportunity by discovery in the action to obtain the information sought; or (iii) discovery is unduly burdensome or expensive, taking into account the needs of the case, the amount in controversy limitations on the party's resources, and the importance of the issues at stake in the litigation. The court may act upon its own initiative after reasonable notice or pursuant to a motion under § 15-6-26(c) . (2) Insurance agreements. A party may obtain discovery of the existence and contents of any insurance agreement under which any person carrying on an insurance business may be liable to satisfy part or all of a judgment which may be entered in the action or to indemnify or reimburse for payments made to satisfy the judgment. Information concerning the insurance agreement is not by reason of disclosure admissible in evidence at trial. For purposes of this paragraph, an application for insurance shall not be treated as part of an insurance agreement. (3) Trial preparation: materials. Subject to the provisions of subdivision (4) of this section, a party may obtain discovery of documents and tangible things otherwise discoverable under subdivision (1) of this section and prepared in anticipation of litigation or for trial by or for another party or by or for that other party's representative (including such other party's attorney, consultant, surety, indemnitor, insurer, or agent) only upon a showing that the party seeking discovery has substantial need of the materials in the preparation of the party's case and that the party is unable without undue hardship to obtain the substantial equivalent of the materials by other means. In ordering discovery of such materials when the required showing has been made, the court shall protect against disclosure of the mental impressions, conclusions, opinions, or legal theories of an attorney or other representative of a party concerning the litigation. A party may obtain without the required showing a statement concerning the action or its subject matter previously made by that party. Upon request, a person not a party may obtain without the required showing a statement concerning the action or its subject matter previously made by that person. If the request is refused, the person may move for a court order. The provisions of subdivision 15-6-37(a) (4) apply to award of expenses incurred in relation to the motion. For purposes of this paragraph, a statement previously made is (A) a written statement signed or otherwise adopted or approved by the person making it, or (B) a stenographic, mechanical, electrical, or other recording, or a transcription thereof, which is a substantially verbatim recital of an oral statement by the person making it and contemporaneously recorded. (4) Trial preparation: experts. Discovery of facts known and opinions held by experts, otherwise discoverable under the provisions of subdivision (1) of this rule and acquired or developed in anticipation of litigation or for trial may be obtained only as follows: (A)(i) A party may through interrogatories require any other party to identify each person whom the other party expects to call as an expert witness at trial, to state the subject matter on which the expert is expected to testify, and to state the substance of the facts and opinions to which the expert is expected to testify and a summary of the grounds for each opinion. A party may also take the testimony of each such expert witness by deposition upon oral examination. (ii) Upon motion, the court may order further discovery by other means, subject to such restrictions as to scope and such provisions, pursuant to subdivision (4)(C) of this section, concerning fees and expenses as the court may deem appropriate. (B) Trial-preparation for draft reports or disclosures. Subdivision 15-6-26(b) (3) protects drafts of any report prepared by any witness who is retained or specially employed to provide expert testimony in the case or one whose duties as the party's employee regularly involves giving expert testimony, regardless of the form in which the draft is recorded. (C) Trial preparation protection for communication between a party's attorney and expert witnesses. Subdivision 15-6-26(b) (3) protects communications between the party's attorney and any witness who is retained or specially employed to provide expert testimony in the case or one whose duties as the party's employee regularly involve giving expert testimony, regardless of the form of the communications, except to the extent that the communications: (i) Relate to compensation for the expert's study or testimony; (ii) Identify facts or data that the party's attorney provided and that the expert considered in forming the opinion to be expressed; or (iii) Identify assumptions that the party's attorney provided and that the expert relied on in forming the opinions to be expressed. (D) A party may discover facts known or opinions held by an expert who has been retained or specially employed by another party in anticipation of litigation or preparation for trial and who is not expected to be called as a witness at trial, only as provided in § 15-6-35(b) or upon a showing of exceptional circumstances under which it is impracticable for the party seeking discovery to obtain facts or opinions on the same subject by other means. (E) Unless manifest injustice would result, (i) the court shall require that the party seeking discovery pay the expert a reasonable fee for time spent in responding to discovery under subdivisions (4)(A)(ii) and (4)(B) of this section; and (ii) with respect to discovery obtained under subdivision (4)(A) (ii) of this section the court may require, and with respect to discovery obtained under subdivision (4)(B) of this section the court shall require, the party seeking discovery to pay the other party a fair portion of the fees and expenses reasonably incurred by the latter party in obtaining facts and opinions from the expert. (5) Claims of privilege or protection of trial preparation materials. When a party withholds information otherwise discoverable under these rules by claiming that it is privileged or subject to protection as trial preparation material, the party shall make the claim expressly and shall describe the nature of the documents, communications, or things not produced in a manner that, without revealing information itself privileged or protected, will enable other parties to assess the applicability of the privilege or protection.

Upon motion by a party or by the person from whom discovery is sought or has been taken, or other person who would be adversely affected, accompanied by a certification that the movant has in good faith conferred or attempted to confer with other affected parties in an effort to resolve the dispute without court action, and for good cause shown, the court in which the action is pending, on matters relating to a deposition, interrogatories, or other discovery, or alternatively, the court in the circuit where the deposition is to be taken may make any order which justice requires to protect a party or person from annoyance, embarrassment, oppression, or undue burden or expense, including one or more of the following: (1) That the discovery not be had; (2) That the discovery may be had only on specified terms and conditions, including a designation of the time and place; (3) That the discovery may be had only by a method of discovery other than that selected by the party seeking discovery; (4) That certain matters not be inquired into, or that the scope of the discovery be limited to certain matters; (5) That discovery be conducted with no one present except persons designated by the court; (6) That a deposition after being sealed be opened only by order of the court; (7) That a trade secret or other confidential research, development, or commercial information not be disclosed or be disclosed only in a designated way; (8) That the parties simultaneously file specified documents or information enclosed in sealed envelopes to be opened as directed by the court; (9) That depositions, interrogatories, admissions, other discovery, documents, and exhibits attached to motions, or portions of such documents, be sealed unless and until opened at the direction of the court. If the motion for a protective order is denied in whole or in part, the court may, on such terms and conditions as are just, order that any party or person provide or permit discovery. The provisions of subdivision 15-6-37(a)(4) apply to the award of expenses incurred in relation to the motion. Source: SDC 1939 & Supp 1960, § 36.0516; SD RCP, Rule 30 (b), as adopted by Sup. Ct.

July 1, 2006. 15-6-26(d). Sequence and timing of discovery. Unless the court upon motion, for the convenience of parties and witnesses and in the interests of justice, orders otherwise, methods of discovery may be used in any sequence and the fact that a party is conducting discovery, whether by deposition or otherwise, shall not operate to delay any other party's discovery. Source: Supreme Court Rule 76-3, § 2. 15-6-26(e). Supplementation of responses. A party who has responded to a request for discovery with a response that was complete when made is under a duty to supplement or correct the response to include information thereafter acquired if ordered by the court or in the following circumstances: (1) A party is under a duty to supplement at appropriate intervals the party's response to a discovery request authorized under subdivision (a) if the party learns that in some material respect the response is incomplete or incorrect and if the additional or corrective information has not otherwise been made known to the other parties during the discovery process or in writing. With respect to testimony of an expert, the duty extends to information contained in any expert report, discovery response concerning expert's opinions and any deposition of the expert. (2) A party is under a duty seasonably to amend a prior response to an interrogatory, request for production, or request for admission if the party learns that the response is in some material respect incomplete or incorrect and if the additional or corrective information has not otherwise been made known to the other parties during the discovery process or in writing. (3) A duty to supplement responses may be imposed by order of the court, agreement of the parties, or at any time prior to trial through new requests for supplementation of prior responses.

Depositions before action. (1) Petition. A person who desires to perpetuate the person's own testimony or that of another person regarding any matter that may be cognizable in any court of this state may file a verified petition in the circuit court in any county which would be the proper place of trial of such matter. The petition shall be entitled in the name of the petitioner and shall show: (A) That the petitioner expects to be a party to an action cognizable in a court of this state but is presently unable to bring it or cause it to be brought; (B) The subject matter of the expected action and the petitioner's interest therein; (C) The facts which the petitioner desires to establish by the proposed testimony and the petitioner's reasons for desiring to perpetuate it; (D) The names or a description of the persons the petitioner expects will be adverse parties and their addresses so far as known; and (E) The names and addresses of the persons to be examined and the substance of the testimony which the petitioner expects to elicit from each; and shall ask for an order authorizing the petitioner to take the depositions of the persons to be examined named in the petition, for the purpose of perpetuating their testimony. (2) Notice and Service. The petitioner shall thereafter serve a notice upon each person named in the petition as an expected adverse party, together with a copy of the petition, stating that the petitioner will apply to the court, at a time and place named therein, for the order described in the petition. At least twenty days before the date of hearing the notice shall be served either within or without the state in the manner provided in § 15-6-4(d) for service of summons, but if such service cannot with due diligence be made upon any expected adverse party named in the petition, the court may make such order as is just for service by publication or otherwise and shall appoint, for persons not served in the manner provided in § 15-6-4(d), an attorney who shall represent them, and in case they are not otherwise represented, shall cross-examine the deponent. If any expected adverse party is a minor or incompetent the provisions of § 15-6-17(c) apply. (3) Order and Examination. If the court is satisfied that the perpetuation of the testimony may prevent a failure or delay of justice, it shall make an order designating or describing the persons whose depositions may be taken and specifying the subject matter of the examination and whether the depositions shall be taken upon oral examination or written interrogatories. The depositions may then be taken in accordance with this chapter; and the court may make orders of the character provided for by §§ 15-6-34 and
