cation may be permitted to intervene in the action. In exercising its discretion the court shall consider whether the intervention will unduly delay or prejudice the adjudication of the rights of the original parties.

RULE 26. DEPOSITIONS PENDING ACTION.

(a) WHEN DEPOSITIONS MAY BE TAKEN. Any party may take the testimony of any person, including a party, by deposition upon oral examination or written interrogatories for the purpose of discovery or for use as evidence in the action or for both purposes. After commencement of the action the deposition may be taken without leave of court, except that leave, granted with or without notice, must be obtained if notice of the taking is served by the plaintiff within 20 days after commencement of the action. The attendance of witnesses may be compelled by the use of subpoena as provided in Rule 45. Depositions shall be taken only in accordance with these rules. The deposition of a person confined in prison may be taken only by leave of court on such terms as the court prescribes.

(b) SCOPE OF EXAMINATION. Unless otherwise ordered by the court as provided by Rule 30 (b) or (d), the deponent may be examined regarding any matter, not privileged, which is relevant to the subject matter involved in the pending action, whether it relates to the claim or defense of the examining party or to the claim or defense of any other party, including the existence, description, nature, custody, condition and location of any books, documents, or other tangible things and the identity and location of persons having knowledge of relevant facts. It is not ground for objection that the testimony will be inadmissible at the trial if the testimony sought appears reasonably calculated to lead to the discovery of admissible evidence.

RULE 27. DEPOSITIONS BEFORE ACTION OR PENDING APPEAL.

(a) BEFORE ACTION.

(3) Order and Examination. If the court is satisfied that the perpetuation of the testimony may prevent a failure or delay of justice, it shall make an order designating or describing the persons whose depositions may be taken and specifying the subject matter of the examination and whether the depositions shall be taken upon oral examination or written interrogatories. The depositions may then be taken in accordance with these rules; and the court may make orders of the character provided for by Rules 34 and 35. For the purpose of applying these rules to depositions for perpetuating testimony, each reference therein to the court in which the action is pending shall be deemed to refer to the court in which the petition for such deposition was filed.

(b) PENDING APPEAL. If an appeal has been taken from a judgment of a district court or before the taking of an appeal if the time therefor has not expired, the district court in which the judgment was rendered may allow the taking of the depositions of witnesses to perpetuate their testimony for use in the event of further proceedings in the district court. In such case the party who desires to perpetuate the testimony may make a motion in the district court for leave to take the depositions, upon the same notice and service thereof as if the action was pending in the district court. The motion shall show (1) the names and addresses of persons to be examined and the substance of the testimony which he expects to elicit from each; (2) the reasons for perpetuating their testimony. If the court finds that the perpetuation of the testimony is proper to avoid a failure or delay of justice, it may make an order allowing the depositions to be taken and may

make orders of the character provided for by Rules 34 and 35, and thereupon the depositions may be taken and used in the same manner and under the same conditions as are prescribed in these rules for depositions taken in actions pending in the district court.

RULE 28. PERSONS BEFORE WHOM DEPOSITIONS MAY BE ΤΑΚΕΝ.

(a) WITHIN THE UNITED STATES. Within the United States or within a territory or insular possession subject to the dominion of the United States, depositions shall be taken before an officer authorized to administer oaths by the laws of the United States or of the place where the examination is held, or before a person appointed by the court in which the action is pending. A person so appointed has power to administer oaths and take testimony.

RULE 33. INTERROGATORIES TO PARTIES.

Any party may serve upon any adverse 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, by any officer or agent, who shall furnish such information as is available to the party. Interrogatories may be served after commencement of the action and without leave of court, except that, if service is made by the plaintiff within 10 days after such commencement, leave of court granted with or without notice must first be obtained. The interrogatories shall be answered separately and fully in writing under oath. The answers shall be signed by the person making them; and the party upon whom the interrogatories have been served shall serve a copy of the answers on the party submitting the interrogatories within 15 days after the service of the interrogatories, unless the court, on motion and notice and for good cause shown, enlarges or shortens the time. Within 10 days after service of interrogatories a party may

serve written objections thereto together with a notice of hearing the objections at the earliest practicable time. Answers to interrogatories to which objection is made shall be deferred until the objections are determined.

Interrogatories may relate to any matters which can be inquired into under Rule 26 (b), and the answers may be used to the same extent as provided in Rule 26 (d) for the use of the deposition of a party. Interrogatories may be served after a deposition has been taken, and a deposition may be sought after interrogatories have been answered, but the court, on motion of the deponent or the party interrogated, may make such protective order as justice may require. The number of interrogatories or of sets of interrogatories to be served is not limited except as justice requires to protect the party from annoyance, expense, embarrassment, or oppression. The provisions of Rule 30 (b) are applicable for the protection of the party from whom answers to interrogatories are sought under this rule.

RULE 34. DISCOVERY AND PRODUCTION OF DOCUMENTS AND THINGS FOR INSPECTION, COPYING, OR PHOTO

GRAPHING.

Upon motion of any party showing good cause therefor and upon notice to all other parties, and subject to the provisions of Rule 30 (b), the court in which an action is pending may (1) order any party to produce and permit the inspection and copying or photographing, by or on behalf of the moving party, of any designated documents, papers, books, accounts, letters, photographs, objects, or tangible things, not privileged, which constitute or contain evidence relating to any of the matters within the scope of the examination permitted by Rule 26 (b) and which are in his possession, custody, or control; or (2) order any party to permit entry upon designated land or other property in his possession or control for the purpose of inspecting, measuring, surveying, or photographing the

property or any designated object or operation thereon within the scope of the examination permitted by Rule 26 (b). The order shall specify the time, place, and manner of making the inspection and taking the copies and photographs and may prescribe such terms and conditions as are just.

RULE 36. ADMISSION OF FACTS AND OF GENUINENESS OF DOCUMENTS.

(a) REQUEST FOR ADMISSION. After commencement of an action a party may serve upon any other party a written request for the admission by the latter of the genuineness of any relevant documents described in and exhibited with the request or of the truth of any relevant matters of fact set forth in the request. If a plaintiff desires to serve a request within 10 days after commencement of the action leave of court, granted with or without notice, must be obtained. Copies of the documents shall be served with the request unless copies have already been furnished. Each of the matters of which an admission is requested shall be deemed admitted unless, within a period designated in the request, not less than 10 days after service thereof or within such shorter or longer time as the court may allow on motion and notice, the party to whom the request is directed serves upon the party requesting the admission either (1) a sworn statement denying specifically the matters of which an admission is requested or setting forth in detail the reasons why he cannot truthfully admit or deny those matters or (2) written objections on the ground that some or all of the requested admissions are privileged or irrelevant or that the request is otherwise improper in whole or in part, together with a notice of hearing the objections at the earliest practicable time. If written objections to a part of the request are made, the remainder of the request shall be answered within the period designated in the request. A denial shall fairly meet the substance of the requested admission, and when
