(a) Availability; Procedures for Use. Any party may serve upon any other party written interrogatories 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. Interrogatories may, without leave of court, be served upon the plaintiff after commencement of the action and upon any other party with or after service of the summons and complaint upon that party.
Each interrogatory shall be answered separately and fully in writing under oath, unless it is objected to, in which event the reasons for objection shall be stated in lieu of an answer. The interrogatory being answered, or objected to, shall be reproduced before the answer or objection. The answers are to be signed by the person making them, and the objections signed by the attorney making them. The party upon whom the interrogatories have been served shall serve a copy of the answers, and objections if any, within 30 days after the service of the interrogatories, except that a defendant may serve answers or objections within 42 days after service of the summons and complaint upon that defendant. Any Superior Judge may allow a shorter or longer time. The party submitting the interrogatories may move for an order under Rule 37(a) with respect to any objection to or other failure to answer an interrogatory.
(b) Scope; Use at Trial. Interrogatories may relate to any matters which can be inquired into under Rule 26(b), and the answers may be used to the extent permitted by the rules of evidence.
An interrogatory otherwise proper is not necessarily objectionable merely because an answer to the interrogatory involves an opinion or contention that relates to fact or the application of law to fact, but the Presiding Judge may order that such an interrogatory need not be answered until after designated discovery has been completed or until a pretrial conference or other later time.
(c) Option To Produce Business Records. 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 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.

Notes

Reporter’s Notes—2018 Amendment: Rule 33(a) is amended to change its 45-day time period to 42 days consistent with the simultaneous “day is a day” amendments to V.R.C.P. 6.

Reporter’s Notes—2009 Amendment: V.R.C.P. 33(c) is amended as part of a series of amendments conforming the Vermont Rules of Civil Procedure to 2006 amendments of the Federal Rules of Civil Procedure that made specific provision for discovery of electronically stored information. See Reporter’s Notes to simultaneous amendment of V.R.C.P. 26. The present amendment is identical to the 2006 amendment of F.R.C.P. 33(d), essentially applying the procedure already in effect for business records to such records that are electronically stored. See Advisory Committee’s Note to that amendment.

Reporter’s Notes—1985 Amendment: Rule 33(a) is amended to require that answers or objections to interrogatories repeat the interrogatory involved before the answer or objections. While this requirement may be a minor inconvenience for the person responding to the interrogatories, it is a great aid to the proponent and the court in ruling on objections or use of the interrogatories at trial. This amendment will also apply in district court. See District Court Civil Rule 33.

Reporter’s Notes—1982 Amendment: Rule 33(c) is amended as part of a series of amendments to the discovery rules following the recent amendments to the Federal Rules of Civil Procedure. See Reporter’s Notes—1982 Amendments to Rule 26. Experience in the federal courts showed abuses of the option to specify records and make them available for inspection. The records may be so extensive that the party seeking information will not be able to find it. Under the amended language the party responding to the discovery request must provide such detail to enable the party seeking the information to locate and identify it as readily as the party responding to discovery.

Reporter’s Notes: This rule is basically similar to former County Court Rule 4.2 (applicable in chancery by virtue of former Chancery Rule 56), which was based on former Federal Rule 33. The rule, however, contains a number of changes made in the federal rule by the 1970 amendments. Rule 33(a) provides that interrogatories may, without leave of court, be served upon plaintiff at any time after commencement of the action and upon any other party at any time after service of summons and complaint upon him. The requirement of the former rule that parties be “adverse” has been eliminated, in line with the 1970 federal amendments, to prevent obstacles to discovery where parties not technically opposed actually have conflicting interests. The rule changes the former procedure under which objections were to be presented to the court for determination within 10 days after service. Now objections are to be served in lieu of answer and the party submitting the interrogatories must invoke the aid of the court if he wishes an answer. This change, made by the 1970 federal amendments, is intended to make the procedure operate with less judicial intervention. Answers and objections are now to be served within 30 days after service (45 days for a defendant) instead of 15 days as formerly. This change, also from the 1970 federal amendments, is intended both to eliminate the need for motions to extend what, in the federal courts, had proved to be unrealistically short time limits and to assure the defendant ample time to obtain representation. See Reporter’s Notes to Rule 30. Rule 33(b) carries forward the provision of former County Court Rule 4.2 that the scope of inquiry on interrogatories is that available on deposition. The new rule, however, limits the use of answers to “the extent permitted by the rules of evidence.” This provision is more restrictive than that for use of depositions under Rule 32, because there is no opportunity for cross-examination on interrogatories. The second paragraph of Rule 33(b) permits interrogatories that involve “an opinion or contention that relates to fact or the application of law to fact.” Pointing out that the federal cases were divided on the propriety of such interrogatories prior to the addition of this language in the 1970 amendments, the federal Advisory Committee states in justification of the provision, “Efforts to draw sharp lines between facts and opinion have invariably been unsuccessful, and the clear trend of the cases is to permit ‘factual’ opinions. As to requests for opinions or contentions that call for the application of law to fact, they can be most useful in narrowing and sharpening the issues, which is a major purpose of discovery . . . . On the other hand, under the new language, interrogatories may not extend to issues of ‘pure law,’ i.e., legal issues unrelated to the facts of the case.” 48 F.R.D. 487, 524. Abuse of this provision can be corrected by the court in its inherent power to protect the attorney’s work product, recognized in Hickman v. Taylor, 329 U.S. 495 (1947). See Reporter’s Notes to Rules 26(b)(3), 36. Note that answers as to contentions will ordinarily not limit proof at trial. See federal Advisory Committee’s Note, supra. Rule 33(c), also added to the federal rule by the 1970 amendments, permits a party who would have to do research in his business records in order to answer interrogatories to shift the burden of such research to the interrogating party by making the records available to him.

Plain-English Summary

Rule 33 lets any party serve written interrogatories on any other party, to be answered by that party or, if the party served is a corporation, partnership, association, or governmental agency, by an officer or agent who furnishes the information available to the party. Interrogatories may be served on a plaintiff after the action begins and on any other party with or after service of the summons and complaint, without needing the court's permission first.

Each interrogatory has to be answered separately and fully in writing under oath unless it is objected to, in which case the reasons for the objection take the place of an answer. Since a 1985 amendment, the interrogatory itself must be reproduced before the answer or objection, which makes the exchange easier for the court and the other side to follow. The responding party has 30 days to serve answers and objections, except that a defendant gets 42 days from service of the summons and complaint, and a superior judge may shorten or lengthen either period.

Rule 33(b) confirms that interrogatories may probe anything within the scope of Rule 26(b), including opinions or contentions about fact or the application of law to fact, though the presiding judge may put off answering a contention interrogatory until later discovery, a pretrial conference, or some other time. Rule 33(c) offers a shortcut where the answer can be found in business records, including electronically stored information: rather than working out the answer itself, the responding party may point to the records and give the requesting party a reasonable chance to examine, audit, or inspect them, so long as the burden of digging out the answer is about the same for either side.

Frequently Asked Questions

Who has to answer interrogatories served on a corporation or agency?

An officer or agent of the corporation, partnership, association, or governmental agency answers on its behalf, furnishing whatever information is available to the party being served.

How long does a party have to answer interrogatories?

Generally 30 days after service, except that a defendant may serve answers or objections within 42 days after being served with the summons and complaint. A superior judge may allow a shorter or longer time.

What must a party do instead of answering an interrogatory it objects to?

It must state the reasons for the objection in lieu of an answer, and the interrogatory being answered or objected to must be reproduced before the answer or objection.

Can interrogatories ask for a party's opinions or legal contentions?

Yes. An interrogatory is not objectionable merely because the answer involves an opinion or a contention that relates to fact or the application of law to fact, though the presiding judge may order that it need not be answered until designated discovery is complete or a later time.

Can a party just point to its business records instead of answering?

Yes, under Rule 33(c), if the answer can be derived from the party's business records, including electronically stored information, and the burden of working out the answer is substantially the same for both sides, it is a sufficient answer to specify the records and give the requesting party a reasonable opportunity to examine, audit, or inspect them.
