obtaining the order, including reasonable attorney's fees. If the motion is denied and if the court finds that the motion was made without substantial justification, the court shall require the examining party or the attorney advising the motion or both of them to pay to the refusing party or witness the amount of the reasonable expenses incurred in opposing the motion, including reasonable attorney's fees. (b) FAILURE TO COMPLY WITH ORDER.

(1) Contempt. If a party or other witness refuses to be sworn or refuses to answer any question after being directed to do so by the court in the district in which the deposition is being taken, the refusal may be considered a contempt of that court.

(2) Other Consequences. If any party or an officer or managing agent of a party refuses to obey an order made under subdivision (a) of this rule requiring him to answer designated questions, or an order made under Rule 34 to produce any document or other thing for inspection, copying, or photographing or to permit it to be done, or to permit entry upon land or other property, or an order made under Rule 35 requiring him to submit to a physical or mental examination, the court may make such orders in regard to the refusal as are just, and among others the following:

(i) An order that the matters regarding which the questions were asked, or the character or description of the thing or land, or the contents of the paper, or the physical or mental condition of the party, or any other designated facts shall be taken to be established for the purposes of the action in accordance with the claim of the party obtaining the order;

(ii) An order refusing to allow the disobedient party to support or oppose designated claims or defenses, or prohibiting him from introducing in evidence designated documents or things or items of testimony, or from introducing evidence of physical or mental condition;

(iii) An order striking out pleadings or parts thereof, or staying further proceedings until the order is obeyed, or dismissing the action or proceeding or any part thereof, or rendering a judgment by default against the disobedient party;

(iv) In lieu of any of the foregoing orders or in addition thereto, an order directing the arrest of any party or agent of a party for disobeying any of such orders except an order to submit to a physical or mental examination.

(c) EXPENSES ON REFUSAL TO ADмIT. If a party, after being served with a request under Rule 36 to admit the genuineness of any documents or the truth of any matters of fact, serves a sworn denial thereof and if the party requesting the admissions thereafter proves the genuineness of any such document or the truth of any such matter of fact, he may apply to the court for an order requiring the other party to pay him the reasonable expenses incurred in making such proof, including reasonable attorney's fees. Unless the court finds that there were good reasons for the denial or that the admissions sought were of no substantial importance, the order shall be made.

(d) FAILURE OF PARTY TO ATTEND OR SERVE ANSWERS. If a party or an officer or managing agent of a party wilfully fails to appear before the officer who is to take his deposition, after being served with a proper notice, or fails to serve answers to interrogatories submitted

under Rule 33, after proper service of such interrogatories, the court on motion and notice may strike out all or any part of any pleading of that party, or dismiss the action or proceeding or any part thereof, or enter a judgment by default against that party.

(e) FAILURE TO RESPOND TO LETTERS ROGATORY. A subpoena may be issued as provided in Title 28, U. S. C., § 1783, under the circumstances and conditions therein stated.

(f) EXPENSES AGAINST UNITED STATES. Expenses and attorney's fees are not to be imposed upon the United States under this rule. (As amended Dec. 29, 1948, eff. Oct. 20, 1949.)

VI. TRIALS

Rule 38. Jury Trial of Right.

(a) RIGHT PRESERVED. The right of trial by jury as declared by the Seventh Amendment to the Constitution or as given by a statute of the United States shall be preserved to the parties inviolate.

(b) DEMAND. Any party may demand a trial by jury of any issue triable of right by a jury by serving upon the other parties a demand therefor in writing at any time after the commencement of the action and not later than 10 days after the service of the last pleading directed to such issue. Such demand may be indorsed upon a pleading of the party.

(c) SAME: SPECIFICATION OF ISSUES. In his demand a party may specify the issues which he wishes so tried; otherwise he shall be deemed to have demanded trial by jury for all the issues so triable. If he has demanded trial by jury for only some of the issues, any other party within 10 days after service of the demand or such lesser time as the court may order, may serve a demand for trial by jury of any other or all of the issues of fact in the action.

(d) WAIVER. The failure of a party to serve a demand as required by this rule and to file it as required by Rule 5 (d) constitutes a waiver by him of trial by jury. A demand for trial by jury made as herein provided may not be withdrawn without the consent of the parties. Rule 39. Trial by Jury or by the Court.

(a) BY JURY. When trial by jury has been demanded as provided in Rule 38, the action shall be designated upon the docket as a jury action. The trial of all issues so demanded shall be by jury, unless (1) the parties or their attorneys of record, by written stipulation filed with the court or by an oral stipulation made in open court and entered in the record, consent to trial by the court sitting without a jury or (2) the court upon motion or of its own initiative finds that a right of trial by jury of some or all of those issues does not exist under the Constitution or statutes of the United States.

(b) BY THE COURT. Issues not demanded for trial by jury as provided in Rule 38 shall be tried by the court; but, notwithstanding the failure of a party to demand a jury in an action in which such a demand might have been made of right, the court in its discretion upon motion may order a trial by a jury of any or all issues.

(c) ADVISORY JURY AND TRIAL BY CONSENT. In all actions not triable of right by a jury the court upon motion or of its own initiative may try any issue with an advisory jury or, except in actions against the United States when a statute of the United States provides for trial

without a jury, the court, with the consent of both parties, may order a trial with a jury whose verdict has the same effect as if trial by jury had been a matter of right.

Rule 40. Assignment of Cases for Trial. The district courts shall provide by rule for the placing of actions upon the trial calendar (1) without request of the parties or (2) upon request of a party and notice to the other parties or (3) in such other manner as the courts deem expedient. Precedence shall be given to actions entitled thereto by any statute of the United States.

Rule 41. Dismissal of Actions.

(a) VOLUNTARY DISMISSAL: EFFECT THEREOF.

(1) By Plaintiff; by Stipulation. Subject to the provisions of Rule 23 (c), of Rule 66, and of any statute of the United States, an action may be dismissed by the plaintiff without order of court (i) by filing a notice of dismissal at any time before service by the adverse party of an answer or of a motion for summary judgment, whichever first occurs, or (ii) by filing a stipulation of dismissal signed by all parties who have appeared in the action. Unless otherwise stated in the notice of dismissal or stipulation, the dismissal is without prejudice, except that a notice of dismissal operates as an adjudication upon the merits when filed by a plaintiff who has once dismissed in any court of the United States or of any state an action based on or including the same claim.

(2) By Order of Court. Except as provided in paragraph (1) of this subdivision of this rule, an action shall not be dismissed at the plaintiff's instance save upon order of the court and upon such terms and conditions as the court deems proper. If a counterclaim has been pleaded by a defendant prior to the service upon him of the plaintiff's motion to dismiss, the action shall not be dismissed against the defendant's objection unless the counterclaim can remain pending for indepen/lent_adjudication by the court. Unless otherwise specified in the order, a dismissal under this paragraph is without prejudice.

(b) INVOLUNTARY DISMISSAL: EFFECT THEREOF. For failure of the plaintiff to prosecute or to comply with these rules or any order of court, a defendant may move for dismissal of an action or of any claim against him. After the plaintiff has completed the presentation of his evidence, the defendant, without waiving his right to offer evidence in the event the motion is not granted, may move for a dismissal on the ground that upon the facts and the law the plaintiff has shown no right to relief. In an action tried by the court without a jury the court as trier of the facts may then determine them and render judgment against the plaintiff or may decline to render any judgment until the close of all the evidence. If the court renders judgment on the merits against the plaintiff, the court shall make findings as provided in Rule 52 (a). Unless the court in its order for dismissal otherwise specifies, a dismissal under this subdivision and any dismissal not provided for in this rule, other than a dismissal for lack of jurisdiction or for improper venue, operates as an adjudication upon the merits.

(c) DISMISSAL OF COUNTERCLAIM, CROSS-CLAIM, OR THIRD-PARTY CLAIM. The provisions of this rule apply to the dismissal of any counterclaim, cross-claim, or third-party claim. A voluntary dismissal by the claimant alone pursuant to paragraph (1) of subdivision

(a) of this rule shall be made before a responsive pleading is served if there is none, before the introduction of evidence at the trial or hearing.

or,

(d) COSTS OF PREVIOUSLY DISMISSED ACTION. If a plaintiff who has once dismissed an action in any court commences an action based upon or including the same claim against the same defendant, the court may make such order for the payment of costs of the action previously dismissed as it may deem proper and may stay the proceedings in the action until the plaintiff has complied with the order. (As amended Dec. 27, 1946, eff. Mar. 19, 1948.)

Rule 42. Consolidation; Separate Trials.

(a) CONSOLIDATION. When actions involving a common question of law or fact are pending before the court, it may order a joint hearing or trial of any or all the matters in issue in the actions; it may order all the actions consolidated; and it may make such orders concerning proceedings therein as may tend to avoid unnecessary costs or delay.

(b) SEPARATE TRIALS. The court in furtherance of convenience or to avoid prejudice may order a separate trial of any claim, cross-claim, counterclaim, or third-party claim, or of any separate issue or of any number of claims, cross-claims, counterclaims, third-party claims, or issues.

Rule 43. Evidence.

(a) FORM AND ADMISSIBILITY. In all trials the testimony of witnesses shall be taken orally in open court, unless otherwise provided by these rules. All evidence shall be admitted which is admissible under the statutes of the United States, or under the rules of evidence heretofore applied in the courts of the United States on the hearing of suits in equity, or under the rules of evidence applied in the courts of general jurisdiction of the state in which the United States court is held. In any case, the statute or rule which favors the reception of the evidence governs and the evidence shall be presented according to the most convenient method prescribed in any of the statutes or rules to which reference is herein made. The competency of a witness to testify shall be determined in like manner.

(b) SCOPE OF EXAMINATION AND CROSS-EXAMINATION. A party may interrogate any unwilling or hostile witness by leading questions. A party may call an adverse party or an officer, director, or managing agent of a public or private corporation or of a partnership or association which is an adverse party, and interrogate him by leading questions and contradict and impeach him in all respects as if he had been called by the adverse party, and the witness thus called may be contradicted and impeached by or on behalf of the adverse party also, and may be cross-examined by the adverse party only upon the subject matter of his examination in chief.

(c) RECORD OF EXCLUDED EVIDENCE. In an action tried by a jury, if an objection to a question propounded to a witness is sustained by the court, the examining attorney may make a specific offer of what he expects to prove by the answer of the witness. The court may require the offer to be made out of the hearing of the jury. The court may add such other or further statement as clearly shows the character of the evidence, the form in which it was offered, the objection made, and the ruling thereon. In actions tried without a jury the same procedure may be followed, except that the court upon request shall take

and report the evidence in full, unless it clearly appears that the evidence is not admissible on any ground or that the witness is privileged.

(d) AFFIRMATION IN LIEU OF OATH. Whenever under these rules an oath is required to be taken, a solemn affirmation may be accepted in lieu thereof.

(e) EVIDENCE ON MOTIONS. When a motion is based on facts not appearing of record the court may hear the matter on affidavits presented by the respective parties, but the court may direct that the matter be heard wholly or partly on oral testimony or depositions. Rule 44. Proof of Official Record.

(a) AUTHENTICATION OF COPY. An official record or an entry therein, when admissible for any purpose, may be evidenced by an official publication thereof or by a copy attested by the officer having the legal custody of the record, or by his deputy, and accompanied with a certificate that such officer has the custody. If the office in which the record is kept is within the United States or within a territory or insular possession subject to the dominion of the United States, the certificate may be made by a judge of a court of record of the district or political subdivision in which the record is kept, authenticated by the seal of the court, or may be made by any public officer having a seal of office and having official duties in the district or political subdivision in which the record is kept, authenticated by the seal of his office. If the office in which the record is kept is in a foreign state or country, the certificate may be made by a secretary of embassy or legation, consul general, consul, vice consul, or consular agent or by any officer in the foreign service of the United States stationed in the foreign state or country in which the record is kept, and authenticated by the seal of his office.

(b) PROOF OF LACK OF RECORD. A written statement signed by an officer having the custody of an official record or by his deputy that after diligent search no record or entry of a specified tenor is found to exist in the records of his office, accompanied by a certificate as above provided, is admissible as evidence that the records of his office contain no such record or entry.

(c) OTHER PROOF. This rule does not prevent the proof of official records or of entry or lack of entry therein by any method authorized by any applicable statute or by the rules of evidence at common law. Rule 45. Subpoena.

(a) FOR ATTENDANCE OF WITNESSES; FORM; ISSUANCE. Every subpoena shall be issued by the clerk under the seal of the court, shall state the name of the court and the title of the action, and shall command each person to whom it is directed to attend and give testimony at a time and place herein specified. The clerk shall issue a subpoena, or a subpoena for the production of documentary evidence, signed and sealed but otherwise in blank, to a party requesting it, who shall fill it in before service.

(b) FOR PRODUCTION OF DOCUMENTARY EVIDENCE. A subpoena may also command the person to whom it is directed to produce the books, papers, documents, or tangible things designated therein; but the court, upon motion made promptly and in any event at or before the time specified in the subpoena for compliance therewith, may (1) quash or modify the subpoena if it is unreasonable and oppres
