ation or governmental agency in accordance with the provisions of Rule 30 (b)(6).

Within 30 days after the notice and written questions are served, a party may serve cross questions upon all other parties. Within 10 days after being served with cross questions, a party may serve redirect questions upon all other parties. Within 10 days after being served with redirect questions, a party may serve recross questions upon all other parties. The court may for cause shown enlarge or shorten the time.

(b) Officer to take responses and prepare record.-A copy of the notice and copies of all questions served shall be delivered by the party taking the deposition to the officer designated in the notice, who shall proceed promptly, in the manner provided by Rule 30 (c), (e), and (f), to take the testimony of the witness in response to the questions and to prepare, certify, and file or mail the deposition, attaching thereto the copy of the notice and the questions received by him.

(c) Notice of filing.—When the deposition is filed the party taking it shall promptly give notice thereof to all other parties.

Rule 32. Use of depositions in court proceedings

(a) Use of depositions.-At the trial or upon the hearing of a motion or an interlocutory proceeding, any part or all of a deposition, so far as admissible under the rules of evidence applied as though the witness were then present and testifying, may be used against any party who was present or represented at the taking of the deposition or who had reasonable notice thereof, in accordance with any of the following provisions:

(1) Any deposition may be used by any party for the purpose of contradicting or impeaching the testimony of deponent as a witness.

(2) The deposition of a party or of anyone who at the time of taking the deposition was an officer, director,

or managing agent, or a person designated under Rule 30 (b)(6) or 31 (a) to testify on behalf of a public or private corporation, partnership or association or governmental agency which is a party may be used by an adverse party for any purpose.

(3) The deposition of a witness, whether or not a party, may be used by any party for any purpose if the court finds: (A) that the witness is dead; or (B) that the witness is at a greater distance than 100 miles from the place of trial or hearing, or is out of the United States, unless it appears that the absence of the witness was procured by the party offering the deposition; or (C) that the witness is unable to attend or testify because of age, illness, infirmity, or imprisonment; or (D) that the party offering the deposition has been unable to procure the attendance of the witness by subpoena; or (E) upon application and notice, that such exceptional circumstances exist as to make it desirable, in the interest of justice and with due regard to the importance of presenting the testimony of witnesses orally in open court, to allow the deposition to be used.

(4) If only part of a deposition is offered in evidence by a party, an adverse party may require him to introduce any other part which ought in fairness to be considered with the part introduced, and any party may introduce any other parts.

Substitution of parties pursuant to Rule 25 does not affect the right to use depositions previously taken; and, when an action in any court of the United States or of any State has been dismissed and another action involving the same subject matter is afterward brought between the same parties or their representatives or successors in interest, all depositions lawfully taken and duly filed in the former action may be used in the latter as if originally taken therefor.

(b) Objections to admissibility.-Subject to the provisions of Rule 28 (b) and subdivision (d)(3) of this rule, objection may be made at the trial or hearing to

receiving in evidence any deposition or part thereof for any reason which would require the exclusion of the evidence if the witness were then present and testifying.

(c) Effect of taking or using depositions.-A party does not make a person his own witness for any purpose by taking his deposition. The introduction in evidence of the deposition or any part thereof for any purpose other than that of contradicting or impeaching the deponent makes the deponent the witness of the party introducing the deposition, but this shall not apply to the use by an adverse party of a deposition under subdivision (a)(2) of this rule. At the trial or hearing any party may rebut any relevant evidence contained in a deposition whether introduced by him or by any other party.

(d) Effect of errors and irregularities in depositions.(1) As to notice.-All errors and irregularities in the notice for taking a deposition are waived unless written objection is promptly served upon the party giving the notice.

(2) As to disqualification of officer.-Objection to taking a deposition because of disqualification of the officer before whom it is to be taken is waived unless made before the taking of the deposition begins or as soon thereafter as the disqualification becomes known or could be discovered with reasonable diligence.

(3) As to taking of deposition.—

(A) Objections to the competency of a witness or to the competency, relevancy, or materiality of testimony are not waived by failure to make them before or during the taking of the deposition, unless the ground of the objection is one which might have been obviated or removed if presented at that time.

(B) Errors and irregularities occurring at the oral examination in the manner of taking the deposition, in the form of the questions or answers, in the oath or affirmation, or in the conduct of parties, and errors of any kind which might be obviated, removed, or cured if

promptly presented, are waived unless seasonable objection thereto is made at the taking of the deposition.

(C) Objections to the form of written questions submitted under Rule 31 are waived unless served in writing upon the party propounding them within the time allowed for serving the succeeding cross or other questions and within 5 days after service of the last questions authorized.

(4) As to completion and return of deposition.-Errors and irregularities in the manner in which the testimony is transcribed or the deposition is prepared, signed, certified, sealed, indorsed, transmitted, filed, or otherwise dealt with by the officer under Rules 30 and 31 are waived unless a motion to suppress the deposition or some part thereof is made with reasonable promptness after such defect is, or with due diligence might have been, ascertained.

Rule 33. Interrogatories to parties

(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 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 and complaint 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.

(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 interroga-tory 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 pre-trial 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 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. Rule 34. Production of documents and things and entry upon land for inspection and other purposes

(a) Scope.-Any party may serve on any other party a request (1) to produce and permit the party making the request, or someone acting on his behalf, to inspect and copy, any designated documents (including writings,
