Mont. R. Civ. P. 26
General Provisions Governing Discovery
(a) 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.
(b) Discovery Scope and Limits. Unless otherwise limited by order of the court in
accordance with these rules, the scope of discovery is as follows:
(1) Scope in General. Unless otherwise limited by court order, the scope of
discovery is as follows: Parties may obtain discovery regarding any non-privileged
matter that is relevant to any party’s claim or defense -- including the existence,
description, nature, custody, condition, and location of any documents or other
tangible things and the identity and location of persons who know of any discoverable
matter. The information sought need not be admissible at the trial if the discovery
appears reasonably calculated to lead to the discovery of admissible evidence. All
discovery is subject to the limitations imposed by Rule 26(b)(2)(C).
(2) Limitations on Frequency and Extent.
(A) When Permitted. By order, the court may alter the limits in these rules on
the number of depositions and interrogatories or on the length of depositions
under Rule 30. By order or local rule, the court may also limit the number of
requests under Rule 36.
(B) Specific Limitations on Electronically-Stored Information. A party need not
provide discovery of electronically-stored information from sources that the
party identifies as not reasonably accessible because of undue burden or cost.
On motion to compel discovery or for a protective order, the party from whom
discovery is sought must show that the information is not reasonably accessible
because of undue burden or cost. If that showing is made, the court may
nonetheless order discovery from such sources if the requesting party shows
good cause, considering the limitations of Rule 26(b)(2)(C). The court may
specify conditions for the discovery.
(C) When Required. On motion or on its own, the court must limit the frequency
or extent of discovery otherwise allowed by these rules or by local rule if it
determines that:
(i) the discovery sought is unreasonably cumulative or duplicative, or can
be obtained from some other source that is more convenient, less
burdensome, or less expensive;
(ii) the party seeking discovery has had ample opportunity to obtain the
information by discovery in the action; or
(iii) the burden or expense of the proposed discovery outweighs its likely
benefit, considering the needs of the case, the amount in controversy, the
parties’ resources, the importance of the issues at stake in the action, and
the importance of the discovery in resolving the issues.
(3) Trial Preparation: Materials.
(A) Documents and Tangible Things. Ordinarily, a party may not discover
documents and tangible things that are prepared in anticipation of litigation or
for trial by or for another party or its representative (including the other party’s
attorney, consultant, surety, indemnitor, insurer, or agent). But, subject to Rule
26(b)(4), those materials may be discovered if:
(i) they are otherwise discoverable under Rule 26(b)(1); and
(ii) the party shows that it has substantial need for the materials to prepare
its case and cannot, without undue hardship, obtain their substantial
equivalent by other means.
(B) Protection Against Disclosure. If the court orders discovery of those
materials, it must protect against disclosure of the mental impressions,
conclusions, opinions, or legal theories of a party’s attorney or other
representative concerning the litigation.
(C) Previous Statement. Any party or other person may, on request and without
the required showing, obtain the person’s own previous statement about the
action or its subject matter. If the request is refused, the person may move for a
court order, and Rule 37(a)(5) applies to the award of expenses. A previous
statement is either:
(i) a written statement that the person has signed or approved; or
(ii) a contemporaneous stenographic, mechanical, electrical, or other
recording -- or a transcription of it -- that recites substantially verbatim the
person’s oral statement.
(4) Trial Preparation: Experts. Discovery of facts known and opinions held by
experts, otherwise discoverable under the provisions of subdivision (b)(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.
(ii) A party may depose any person who has been identified as an expert
whose opinions may be presented at trial. Upon motion, the court may order
further discovery by other means, subject to such restrictions as to scope and
such provisions, pursuant to subdivision (b)(4)(C) of this rule, concerning
fees and expenses as the court may deem appropriate.
(B) 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 Rule 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.
(C) 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 (b)(4)(A)(ii) and (b)(4)(B) of this rule; and
(ii) with respect to discovery obtained under subdivision (b)(4)(A)(ii) of
this rule, the court may require, and with respect to discovery obtained
under subdivision (b)(4)(B) of this rule, 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) 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.
(6) Claiming Privilege or Protecting Trial-Preparation Materials.
(A) Information Withheld. When a party withholds information otherwise
discoverable by claiming that the information is privileged or subject to
protection as trial-preparation material, the party must:
(i) expressly make the claim; and
(ii) describe the nature of the documents, communications, or things not
produced or disclosed -- and do so in a manner that, without revealing
information itself privileged or protected, will enable other parties to assess
the claim.
(B) Information Produced. If information produced in discovery is subject to a
claim of privilege or of protection as trial-preparation material, the party making
the claim may notify any party that received the information of the claim and the
basis for it. After being notified, a party must promptly return, sequester, or
destroy the specified information and any copies it has; must not use or disclose
the information until the claim is resolved; must take reasonable steps to retrieve
the information if the party disclosed it before being notified; and may promptly
present the information to the court under seal for a determination of the claim.
The producing party must preserve the information until the claim is resolved.
(c) Protective Orders.
(1) In General. A party or any person from whom discovery is sought may move
for a protective order in the court where the action is pending -- or as an alternative
on matters relating to a deposition, in the court for the district where the deposition
will be taken. Th e motion must include 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. The court may, for good cause, issue an order to
protect a party or person from annoyance, embarrassment, oppression, or undue
burden or expense, including one or more of the following:
(A) forbidding the discovery;
(B) specifying terms, including time and place, for the discovery;
(C) prescribing a discovery method other than the one selected by the party
seeking discovery;
(D) forbidding inquiry into certain matters, or limiting the scope of discovery to
certain matters;
(E) designating the persons who may be present while the discovery is
conducted;
(F) requiring that a deposition be sealed and opened only on court order;
(G) requiring that a trade secret or other confidential research, development, or
commercial information not be revealed or be revealed only in a specified way;
and
(H) requiring that the parties simultaneously file specified documents or
information in sealed envelopes, to be opened as the court directs.
(2) Ordering Discovery. If a motion for protective order is wholly or partly denied,
the court may, on just terms, order that any party or person provide or permit
discovery.
(3) Awarding Expenses. Rule 37(a)(5) applies to the award of expenses.
(d) Sequence and Timing of Discovery. Unless, on motion, the court orders otherwise
for the parties’ and witnesses’ convenience and in the interests of justice:
(1) methods of discovery may be used in any sequence; and
(2) discovery by one party does not require any other party to delay its discovery.
(e) Supplementing Responses.
(1) In General. A party who has responded to an interrogatory, request for
production, or request for admission must supplement or correct its response:
(A) in a timely manner 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; or
(B) as ordered by the court.
(2) Expert witness. For an expert whose opinion is produced in response to
an interrogatory served under Rule 26(b)(4), the party’s duty to supplement
extends both to information included in the response and to information given
during the expert’s deposition. Any additions or changes to this information
must be disclosed by the time of the preparation and submission of the pretrial
order to the court.
(f) Discovery Conference. At any time after commencement of an action, the court may
direct the attorneys for the parties to appear before it for a conference on the subject of
discovery. The court shall do so upon motion by the attorney for any party if the motion
includes:
(1) a statement of the issues as they then appear;
(2) a proposed plan and schedule of discovery;
(3) any limitations proposed to be placed on discovery;
(4) any issues relating to discovery of electronically-stored information, including
the form or forms in which it should be produced;
(5) any other proposed orders with respect to discovery; and
(6) a statement showing that the attorney making the motion has made a reasonable
effort to reach agreement with opposing attorneys in the matters set forth in the
motion. Each party and each party’s attorney are under a duty to participate in good
faith in the framing of a discovery plan if a plan is proposed by the attorney for any
party. Notice of the motion shall be served on all parties. Objections or additions to
matters set forth in the motion shall be served not later than 14 days after service of
the motion.
Following the discovery conference, the court shall enter an order tentatively
identifying the issues for discovery purposes, establishing a plan and schedule for
discovery, including resolution of issues relating to the discovery of electronically-stored information, including the form or forms in which it should be produced, setting
limitations on discovery, if any; and determining such other matters, including the
allocation of expenses, as are necessary for the proper management of discovery in the
action. An order may be altered or amended whenever justice so requires.
(g) Signing Disclosures and Discovery Requests, Responses, and Objections.
(1) Signature Required; Effect of Signature. Every discovery request,
response, or objection must be signed by at least one attorney of record in the
attorney’s own name – or by the party personally, if unrepresented – and must
state the signer’s address. By signing, an attorney or party certifies that to the
best of the person’s knowledge, information, and belief formed after a
reasonable inquiry, it is:
(A) consistent with these rules and warranted by existing law or by a
good faith argument for extending, modifying, or reversing existing
law;
(B) not interposed for any improper purpose, such as to harass, cause
unnecessary delay, or needlessly increase the cost of litigation; and
(C) neither unreasonable nor unduly burdensome or expensive,
considering the needs of the case, prior discovery in the case, the
amount in controversy, and the importance of the issues at stake in the
action.
(2) Failure to Sign. Other parties have no duty to act on an unsigned request,
response, or objection until it is signed, and the court must strike it unless a
signature is promptly supplied after the omission is called to the attorney’s or
party’s attention.
(2) Sanction for Improper Certification. If a certification violates this
rule without substantial justification, the court, on motion or on its own, must
impose an appropriate sanction on the signer, the party on whose behalf the
signer was acting, or both. The sanction may include an order to pay the
reasonable expenses, including attorney fees, caused by the violation.
