(a) Any party may serve written interrogatories upon any other party. Interrogatories may, without leave of court, be served upon any party after service of the summons and complaint. No party may serve more than a total of 50 interrogatories upon any other party unless permitted to do so by the court upon motion, notice and a showing of good cause. In computing the total number of interrogatories each subdivision of separate questions shall be counted as an interrogatory.
(b) The party upon whom the interrogatories have been served shall serve separate written answers or objections to each interrogatory within 30 days after service of the interrogatories, except that a defendant may serve answers or objections within 45 days after service of summons and complaint upon that defendant. The court, on motion and notice and for good cause shown, may enlarge or shorten the time.
(c) Objections shall state with particularity the grounds for the objection and may be served either as a part of the document containing the answers or separately. The party submitting the interrogatories may move for an order under Rule 37.01 with respect to any objection to or other failure to answer an interrogatory. Answers to interrogatories to which objection has been made shall be deferred until the objections are determined.
(d) Answers to interrogatories shall be stated fully in writing and shall be signed under oath or penalty of perjury by the party served or, if the party served is the state, a corporation, a partnership, or an association, by any officer or managing agent, who shall furnish such information as is available. A party shall restate the interrogatory being answered immediately preceding the answer to that interrogatory.
All answers signed under penalty of perjury must have the signature affixed immediately below a declaration using substantially the following language: "I declare under penalty of perjury that everything I have stated in this document is true and correct." In addition to the signature, the date of signing and the county and state where the document was signed shall be noted on the document.
Without leave of court or written stipulation, any party may serve upon any other party written interrogatories, not exceeding 50 in number including all discrete subparts, to be answered by the party served or, if the party served is a public or private corporation or a partnership or association or governmental agency, by any officer or agent, who shall furnish such information as is available to the party. Leave to serve additional interrogatories shall be granted to the extent consistent with the principles of Rule 26.02(a).
(Amended effective January 1, 1997; amended effective July 1, 2015.)
Interrogatories may relate to any matters which can be inquired into pursuant to Rule 26.02, and the answers may be used to the extent permitted by the Minnesota Rules of Evidence.
An interrogatory otherwise proper is not necessarily objectionable merely because its answer involves an opinion or contention that relates to fact or the application of law to fact, but the court may order that such an interrogatory need not be answered until after designated discovery has been completed, a pretrial conference has been held, or at another later time.
Where the answer to an interrogatory may be derived or ascertained from the business records, including electronically stored information, of the party upon whom the interrogatory has been served or from an examination, audit, or inspection of such business records, including a compilation, abstract, or summary thereof, and the burden of deriving or ascertaining the answer is substantially the same for the party serving the interrogatory as for the party served, it is a sufficient answer to such interrogatory to specify the records from which the answer may be derived or ascertained and to afford to the party serving the interrogatory reasonable opportunity to examine, audit, or inspect such records and to make copies, compilations, abstracts, or summaries. A specification shall be in sufficient detail as to permit the interrogating party to locate and to identify, as readily as can the party served, the records from which the answer may be ascertained.
