M.R. Civ. P. 33

(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, complaint, and notice

regarding Electronic Service upon that party. Unless otherwise ordered by the

court, more than one set of interrogatories may be served, but not more than a

total of 30 interrogatories may be served by a party on any other party. Each

distinct subpart in an interrogatory shall be deemed a separate interrogatory

for the purposes of this rule.

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 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 45 days after service of the summons, complaint, and notice regarding

Electronic Service upon that defendant. The court 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. A party in responding to interrogatories shall set forth each

interrogatory in full immediately preceding the party’s answer or objection

thereto.

(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 court 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, or from a compilation, abstract or summary based

thereon, 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.
