South Dakota Civil Discovery Rules and Procedures
South Dakota discovery rules are governed primarily by the South Dakota Codified Laws (SDCL) Chapter 15-6, which contains the state's civil procedure rules. Understanding these specific requirements is critical for effective case management in South Dakota state courts, as the rules differ meaningfully from federal discovery practices and other state systems.
Mandatory Initial Disclosures
South Dakota does not require mandatory initial disclosures like the federal system. SDCL 15-6-26 does not impose an automatic duty to disclose parties, witnesses, documents, or damages calculations before a discovery request is served.
However, parties are required to disclose certain information by rule:
Expert witnesses: Under SDCL 15-6-26(b), parties must disclose expert witnesses at least 30 days before trial unless the court orders otherwise. The disclosure must include the expert's qualifications, opinions, and the facts underlying those opinions.Damage computations: While not automatic, courts may require disclosure of damage calculations through interrogatory responses or court order.This lack of automatic disclosures gives South Dakota practitioners more latitude in withholding information until specifically requested, but also requires more targeted discovery requests early in litigation.
Interrogatories
Numerical limits are a critical constraint in South Dakota discovery:
SDCL 15-6-33(a) limits interrogatories to 25 interrogatories per side, including all subparts. This is a strict count that includes related questions.Subparts (such as "identify the person" and "state their address" as parts of one interrogatory) count toward the 25-interrogatory limit.Exceeding this limit requires court permission under SDCL 15-6-26(f).Time to respond: Defendants and other responding parties have 20 days to respond after service of interrogatories under SDCL 15-6-33(a), or such other time as the court may allow.
Format and content requirements:
Interrogatories must be set out separately and numbered consecutively.Each interrogatory must be clear, concise, and not unduly burdensome.Responses must be signed by the responding party (not just counsel) and must be truthful under oath.A party may object to interrogatories on grounds of privilege, work product, relevance, burden, or other SDCL 15-6-26 limitations.Common pitfalls:
Practitioners frequently violate the 25-interrogatory limit by counting subparts as separate interrogatories. South Dakota courts strictly enforce this limit.Vague objections ("This is unduly burdensome") without specific factual explanation may be overruled.Failure to sign interrogatory responses can result in striking of responses.Requests for Production of Documents
Scope: SDCL 15-6-34 permits parties to request production of "any designated documents, electronically stored information, or tangible things" in the possession, custody, or control of the responding party that are relevant to the subject matter of the action.
Control is the relevant standard, not ownership. A party may need to produce documents it doesn't own but can access or obtain from a third party.
Time to respond: The responding party has 20 days from service to respond to requests for production under SDCL 15-6-34(b).
Format of responses:
The responding party may produce documents as they are kept in the usual course of business, or organized to correspond with the requesting party's categories.If the requesting party objects to the organization, a motion to compel may be necessary.Responses must identify which documents are withheld and on what basis (privilege, work product, etc.).Electronically Stored Information (ESI):
SDCL 15-6-34 requires parties to produce ESI in the "form or forms in which it is ordinarily maintained or in a form or forms in which it is reasonably usable."No automatic duty to search inaccessible data: A party is not required to produce ESI from sources deemed not reasonably accessible due to undue burden or cost, unless the requesting party shows good cause for access to such data.South Dakota does not have detailed ESI protocols comparable to some federal courts, so parties should address ESI issues early through discovery disputes or stipulations.Requests for Admission
Numerical limits: Unlike interrogatories, SDCL 15-6-36 does not specify a numerical limit on requests for admission, though they should be reasonable and not constitute harassment.
Time to respond: The responding party must respond within 20 days of service under SDCL 15-6-36(a).
Deemed-admitted consequences: This is a critical issue in South Dakota practice. Under SDCL 15-6-36(a), if a party fails to serve a timely response to a request for admission, the matter is deemed admitted unless the requesting party withdraws the request or the court relieves the party from the admission.
Deemed admissions are difficult to overcome and are treated as conclusive facts at trial.SDCL 15-6-36(b) allows withdrawal or amendment of admissions only with agreement of the parties or upon good cause shown to the court.Courts are reluctant to grant relief from deemed admissions absent exceptional circumstances.Objections: A party may object on grounds of privilege, work product, relevance, or proportionality, but must do so within the 20-day period.
Depositions
Numerical limits: SDCL 15-6-30(a) permits each side to take up to 10 depositions without court permission. Depositions beyond this limit require court authorization under SDCL 15-6-26(f).
Duration: A deposition is limited to one day of 7 hours unless the parties agree otherwise or the court orders extended time. SDCL 15-6-30(d).
Notice requirements:
A party seeking to depose an opponent or non-party must provide at least 14 days' notice before the deposition, except as otherwise agreed or ordered by the court. SDCL 15-6-30(b).The notice must include the time, place, and method of the deposition.For depositions of non-parties, a subpoena must be issued under SDCL 15-6-45.Who can be deposed:
Any party to the action may be deposed without a subpoena under SDCL 15-6-30(a).Non-parties may be deposed if properly subpoenaed.The deponent may be questioned under oath by either party.Use at trial:
Depositions may be used at trial for impeachment of a witness or to establish testimony of a party who is unavailable to testify.A deposition of a party opponent may be used at trial as substantive evidence of admissions made during the deposition.Practical considerations:
Many depositions in South Dakota occur virtually, though the rules do not prohibit in-person depositions.Recording depositions is permitted; the court reporter or recording device must be clearly identified in the deposition notice.Physical and Mental Examinations
When allowed: SDCL 15-6-35 permits a party to demand a physical or mental examination of another party when the party's physical or mental condition is "in controversy" in the action.
Good cause requirement: The requesting party must show that the examination is necessary and appropriate to the case. SDCL 15-6-35(a) requires the court to issue an order for examination upon a showing of good cause.
Examples of in-controversy:
Personal injury cases where damages are at issueEmployment disputes involving alleged disability or fitness for dutyFamily law matters involving custody or parental fitnessWho can request: The opposing party (not a third party) may demand examination. The examination must be conducted by a healthcare provider qualified to examine the condition at issue.
Required procedures:
The requesting party must serve a demand that specifies the time, place, manner, and conditions of the examination.The court must issue an order if good cause is shown.The examined party is entitled to have a representative present.The examiner must provide a detailed written report of findings within 14 days after the examination (unless extended by agreement or court order).Report reciprocity: The party demanding the examination must provide the report to the examined party. The examined party may then obtain an independent examination at their own cost.
Subpoenas for Non-Parties
Issuance: Subpoenas for non-parties are issued under SDCL 15-6-45. A subpoena must be issued by the court, a clerk of court, or an attorney authorized to practice in South Dakota.
Geographic limits:
A subpoena may command a person to appear at a deposition or trial anywhere within South Dakota (the state's borders), or at such other location as agreed by the parties or ordered by the court.Out-of-state witnesses generally cannot be compelled to appear without consent under South Dakota law, though video depositions may be taken under SDCL 15-6-30(b).Content and service:
The subpoena must specify the time, place, and manner of compliance.If the subpoena commands production of documents or ESI, it must describe the requested materials with reasonable particularity.The subpoena must be served on the non-party at least 14 days before the deposition or trial date, except as ordered by the court.Compliance and enforcement:
Failure to comply with a subpoena may result in contempt of court under SDCL 15-6-45(d).A non-party may file a motion to quash or modify a subpoena on grounds of burden, privilege, or other SDCL 15-6-26 limitations.Expert Discovery
Disclosure requirements: As noted above, expert witnesses must be disclosed at least 30 days before trial under SDCL 15-6-26(b), unless the court orders otherwise.
Required information:
The expert's name, address, and qualificationsA summary of the opinions the expert will expressThe facts, data, or other information underlying those opinionsAny reports prepared by the expertTiming:
Experts must be disclosed well before trial. Discovery often closes 90 days before trial (unless modified by court order or stipulation).Rebuttal experts may be disclosed later if they respond to the opposing party's expert opinions.Deposing experts:
Expert depositions are subject to the same numerical limits (10 depositions per side) and procedural rules as fact depositions under SDCL 15-6-30.Expert depositions are often longer and more intensive than fact depositions, though the one-day, seven-hour limit still applies unless extended.Expert reports should be preserved and produced upon request.Scope of Discovery
Discoverable information: Under SDCL 15-6-26(b), parties may obtain discovery of any information relevant to the claim or defense, unless protected by privilege or work product.
Relevance standard: Information is discoverable if it is relevant to any claim or defense in the action. This is a broad standard that includes information not admissible at trial if it is likely to lead to discovery of admissible evidence.
Proportionality considerations:
SDCL 15-6-26(b) imposes a proportionality requirement: discovery must be proportional to the needs of the case, considering the importance of the discovery, the parties' resources, and the burden and expense of the proposed discovery.A party may limit discovery if the burden clearly outweighs the benefit, but must explain this in writing.Common scope disputes:
Litigation hold notices: Information about parties' litigation holds and preservation efforts is generally discoverable.Settlement discussions: Communications made in settlement negotiations are typically protected by state settlement privilege (SDCL 15-6-26(c)).Insurance information: Information about insurance coverage is generally discoverable but may be limited to coverage amounts.Privileges and Work Product
Attorney-client privilege: SDCL 19-13-1 protects confidential communications between attorney and client made for the purpose of obtaining or providing legal advice. This privilege is absolute and does not extend to facts.
Work product doctrine: SDCL 15-6-26(c) protects documents and materials prepared in anticipation of litigation or for trial by a party's attorney or agent, including mental impressions, conclusions, opinions, and legal theories.
Work product is protected unless the opposing party demonstrates substantial need and unavailability of the materials through other sources.Fact work product (as opposed to opinion work product) receives less protection.Privilege logs:
A party claiming privilege must produce a privilege log identifying each withheld document, stating the date, parties, subject matter, and basis for the privilege claim.SDCL 15-6-33(d) requires privilege logs to be provided when asserting privilege in discovery responses.A privilege log must be detailed enough for the opposing party and court to evaluate the privilege claim.Common pitfalls:
General assertions of privilege without specific explanation are insufficient.Inadvertent disclosure of privileged material may waive privilege if the disclosing party fails to provide prompt notice and seek return of the material.Meet and Confer Requirements
Mandatory conference before motion: SDCL 15-6-26(f) requires a party seeking court intervention in a discovery dispute to first certify that the party has attempted in good faith to confer with the opposing party to resolve the dispute without court intervention.
Form of communication:
The meet and confer requirement is satisfied by a good-faith effort to discuss the issue, whether in person, by phone, email, or video conference.Sending a letter stating the dispute may be insufficient if no actual discussion occurs.The timing of the meet and confer is important; it should occur promptly after the dispute arises.What must be discussed:
The specific discovery requests or responses at issueThe basis for any objectionsPotential compromises or limitationsCertifying compliance: A motion to compel or motion for protective order must include a certification that the movant has met and conferred with the opposing party, or explain why such conference was not possible.
Discovery Cutoffs
Timing relative to trial: South Dakota does not have a uniform statewide discovery cutoff rule; instead, cutoffs are typically established by:
Court order in the individual case (often issued at the initial scheduling conference)Stipulation of the partiesLocal rules of the particular district courtTypical practice: Discovery frequently closes 90 days before trial unless modified, with expert disclosures due 30 days before trial and rebuttal expert disclosures due 14 days before trial (or as ordered).
Consequences of late discovery:
Discovery sought after the cutoff may be barred unless the requesting party shows good cause for the delay.A party seeking to introduce evidence not timely discovered may face sanctions or exclusion of that evidence.Protective Orders
Obtaining a protective order: SDCL 15-6-26(c) permits a party to seek a protective order to limit or prevent discovery that is overly burdensome, harassing, or seeks to disclose proprietary or confidential information.
Good cause standard: The party seeking protection must demonstrate good cause, showing that:
The discovery is unduly burdensome or expensiveThe discovery seeks to disclose trade secrets, confidential business information, or other sensitive materialsThe discovery is harassing or primarily seeks to harassTypes of protective orders:
Stipulated protective orders are common and often agreed upon by the parties to allow production of sensitive materials under confidentiality restrictions.Designated confidential designations may limit review of documents to attorneys, experts, and court personnel.Sealed filings may protect highly sensitive information from public disclosure.Procedure: A motion for protective order must be accompanied by a certification of good-faith attempt to confer with the opposing party under SDCL 15-6-26(f).
Motions to Compel
Procedure: SDCL 15-6-26(f) governs motions to compel discovery responses. A party may move to compel if:
A party fails to respond to a discovery requestA party provides an evasive or incomplete responseA party improperly asserts a privilege or objectionPrerequisites:
The moving party must certify good-faith attempt to confer with the opposing party.The motion must be filed within a reasonable time, not as a delay tactic.Burden of proof:
The responding party bears the burden of justifying its objections or failure to respond.If the responding party asserts privilege, it must provide a detailed privilege log supporting the claim.Court's authority:
If the court grants a motion to compel, it may order the responding party to provide the discovery within a specified time.The court may also award attorney's fees and costs to the prevailing party unless the responding party had substantially justified its position or other circumstances make an award unjust.Timing: Parties typically have 10-14 days to respond to a motion to compel before the hearing, though the court's scheduling order controls.
