date of hearing the notice shall be served either within or without the district or state in the manner provided in Rule 4 (d) for service of summons; but if such service cannot with due diligence be made upon any expected adverse party named in the petition, the court may make such order as is just for service by publication or otherwise, and shall appoint, for persons not served in the manner provided in Rule 4 (d), an attorney who shall represent them, and, in case they are not otherwise represented, shall cross-examine the deponent. If any expected adverse party is a minor or incompetent the provisions of Rule 17 (c) apply.

(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. 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.

(4) Use of Deposition. If a deposition to perpetuate testimony is taken under these rules or if, although not so taken, it would be admissible in evidence in the courts of the state in which it is taken, it may be used in any action involving the same subject matter subsequently

brought in a district court of the United States, in accordance with the provisions of Rule 26 (d). (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 the 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 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.

(c) PERPETUATION BY ACTION. This rule does not limit the power of a court to entertain an action to perpetuate testimony.

Rule 28. Persons Before Whom Depositions May Be Taken.

(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.

(b) IN FOREIGN COUNTRIES. In a foreign state or country depositions shall be taken (1) on notice before a secretary of embassy or legation, consul general, consul, vice consul, or consular agent of the United States, or (2) before such person or officer as may be appointed by commission or under letters rogatory. A commission or letters rogatory shall be issued only when necessary or convenient, on application and notice, and on such terms and with such directions as are just and appropriate. Officers may be designated in notices or commissions either by name or descriptive title and letters rogatory may be addressed "To the Appropriate Judicial Authority in [here name the country]".

(c) DISQUALIFICATION FOR INTEREST. No deposition shall be taken before a person who is a relative or employee or attorney or counsel of any of the parties, or is a relative or employee of such attorney or counsel, or is financially interested in the action.

Rule 29. Stipulations Regarding the Taking of Depositions. If the parties so stipulate in writing, depositions may be taken before any person, at any time or place, upon any notice, and in any manner and when so taken may be used like other depositions.

Rule 30. Depositions Upon Oral Examination.

(a) NOTICE OF EXAMINATION: TIME AND PLACE. A party desiring to take the deposition of any person upon oral examination shall give reasonable notice in writing to every other party to the action. The notice shall state the time and place for taking the deposition and the name and address of each person to be examined, if known, and, if the name is not known, a general description sufficient to identify him or the particular class or group to which he belongs. On motion of any party upon whom the

notice is served, the court may for cause shown enlarge or shorten the time.

(b) ORDERS FOR THE PROTECTION OF PARTIES AND DEPONENTS. After notice is served for taking a deposition by oral examination, upon motion seasonably made by any party or by the person to be examined and upon notice and for good cause shown, the court in which the action is pending may make an order that the deposition shall not be taken, or that it may be taken only at some designated place other than that stated in the notice, or that it may be taken only on written interrogatories, or that certain matters shall not be inquired into, or that the scope of the examination shall be limited to certain matters, or that the examination shall be held with no one present except the parties to the action and their officers or counsel, or that after being sealed the deposition shall be opened only by order of the court, or that secret processes, developments, or research need not be disclosed, or that the parties shall simultaneously file specified documents or information enclosed in sealed envelopes to be opened as directed by the court; or the court may make any other order which justice requires to protect the party or witness from annoyance, embarrassment, or oppression.

(c) RECORD OF EXAMINATION; OATH; OBJECTIONS. The officer before whom the deposition is to be taken shall put the witness on oath and shall personally, or by some one acting under his direction and in his presence, record the testimony of the witness. The testimony shall be taken stenographically and transcribed unless the parties agree otherwise. All objections made at the time of the examination to the qualifications of the officer taking the deposition, or to the manner of taking it, or to the evidence pre

sented, or to the conduct of any party, and any other objection to the proceedings, shall be noted by the officer upon the deposition. Evidence objected to shall be taken subject to the objections. In lieu of participating in the oral examination, parties served with notice of taking a deposition may transmit written interrogatories to the officer, who shall propound them to the witness and record the answers verbatim.

TION.

(d) MOTION TO TERMINATE OR LIMIT EXAMINAAt any time during the taking of the deposition, on motion of any party or of the deponent and upon a showing that the examination is being conducted in bad faith or in such manner as unreasonably to annoy, embarrass, or oppress the deponent or party, the court in which the action is pending or the court in the district where the deposition is being taken may order the officer conducting the examination to cease forthwith from taking the deposition, or may limit the scope and manner of the taking of the deposition as provided in subdivision (b). If the order made terminates the examition, it shall be resumed thereafter only upon the order of the court in which the action is pending. Upon demand of the objecting party or deponent, the taking of the deposition shall be suspended for the time necessary to make a motion for an order. In granting or refusing such order the court may impose upon either party or upon the witness the requirement to pay such costs or expenses as the court may deem reasonable.

(e) SUBMISSION TO WITNESS; CHANGES; SIGNING. When the testimony is fully transcribed the deposition shall be submitted to the witness for examination and shall be read to or by him, unless such examination and reading are waived by the witness and by
