action against him, the party to be brought in by amendment (1) has received such notice of the institution of the action that he will not be prejudiced in maintaining his defense on the merits, and (2) knew or should have known that, but for a mistake concerning the identity of the proper party, the action would have been brought against him. The delivery or mailing of the summons and complaint to the Attorney-inCharge, International Trade Field Office, Commercial Litigation Branch, Department of Justice, or an agency or officer who would have been a proper defendant if named, satisfies the requirement of clauses (1) and (2) hereof with respect to the United States or any agency or officer thereof to be brought into the action as a defendant.

(d) Supplemental Pleadings. Upon motion of a party, the court may, upon reasonable notice and upon such terms as are just, permit him to serve a supplemental pleading setting forth transactions or occurrences or events which have happened since the date of the pleading sought to be supplemented. Permission may be granted even though the original pleading is defective in its statements of a claim for relief or defense. If the court deems it advisable that the adverse party plead to the supplemental pleading, it shall so order, specifying the time therefor.

(As amended Jan. 1, 1982.)

Rule 16. Pre-Trial Procedure-Formulating Issues

(a) Pre-Trial Conference. In any action, the court may in its discretion direct the attorneys for the parties to appear before it for a conference to consider:

(1) the simplification of the issues;

(2) the necessity or desirability of amendments to the pleadings;

(3) the possibility of obtaining admissions of fact and of documents which will avoid unnecessary proof;

(4) the limitation of the number of expert witnesses;

(5) the advisability of a preliminary reference of issues to a master for findings to be used as evidence when the trial is to be by jury;

(6) such other matters as may aid in the disposition of the action.

(b) Pre-Trial Order. The court shall make an order which recites the action taken at the conference, the amendments allowed to the pleadings, and the agreements made by the parties as to any of the matters considered, and which limits the issues for trial to those not disposed of by admissions or agreements of counsel; and such order when entered controls the subsequent course of the action, unless modified at the trial to prevent manifest injustice.

TITLE IV-PARTIES

Rule 17. Parties Plaintiff and Defendant-Capacity (a) Real Party in Interest. Every action shall be prosecuted in the name of the real party in interest. An executor, administrator, guardian, bailee, trustee of an express trust, a party with whom or in whose name a contract has been

made for the benefit of another, or a party authorized by statute may sue in his own name without joining with him the party for whose benefit the action is brought; and when a statute of the United States so provides, an action for the use or benefit of another shall be brought in the name of the United States. No action shall be dismissed on the ground that it is not prosecuted in the name of the real party in interest until a reasonable time has been allowed after objection for ratification of commencement of the action by, or joinder or substitution of, the real party in interest; and such ratification, joinder, or substitution shall have the same effect as if the action had been commenced in the name of the real party in interest.

(b) Capacity To Sue or Be Sued. The capacity of an individual, other than one acting in a representative capacity, to sue or be sued shall be determined by the law of his domicile. The capacity of a corporation to sue or be sued shall be determined by the law under which it was organized. In all other cases, capacity to sue or be sued shall be determined by the law of the appropriate state except (1) that a partnership or other unincorporated association, which has no such capacity by the law of such state, may sue or be sued in its common name for the purpose of enforcing for or against it a substantive right existing under the Constitution or laws of the United States, and (2) that the capacity of a receiver appointed by a court of the United States to sue or be sued in a court of the United States is governed by 28 U.S.C. §§ 754 and 959(a).

(c) Infants or Incompetent Persons. Whenever an infant or incompetent person has a representative, such as a general guardian, committee, conservator, or other like fiduciary, the representative may sue or defend on behalf of the infant or incompetent person. If an infant or incompetent person does not have a duly appointed representative he may sue by his next friend or by a guardian ad litem. The court shall appoint a guardian ad litem for an infant or incompetent person not otherwise represented in an action or shall make such other order as it deems proper for the protection of the infant or incompetent person.

Rule 18. Joinder of Claims and Remedies

(a) Joinder of Claims. A party asserting a claim to relief as an original claim, counterclaim, cross-claim, or third-party claim, may join, either as independent or as alternate claims, as many claims, legal or equitable, as he has against an opposing party, except that in an action described in 28 U.S.C. § 1581(a), a party may join claims only if they involve a common issue.

(b) Joinder of Remedies. Whenever a claim is one heretofore cognizable only after another claim has been prosecuted to a conclusion, the two claims may be joined in a single action; but the court shall grant relief in that action only in accordance with the relative substantive rights of the parties. In particular, a plaintiff may state a claim for money and a claim to

have set aside a conveyance fraudulent as to him, without first having obtained a judgment establishing the claim for money.

Rule 19. Joinder of Persons Needed for Just Adjudication

(a) Persons To Be Joined if Feasible. A person shall be joined as a party in the action if (1) in his absence complete relief cannot be accorded among those already parties, or (2) he claims an interest relating to the subject of the action and is so situated that the disposition of the action in his absence may (A) as a practical matter impair or impede his ability to protect that interest, or (B) leave any of the persons already parties subject to a substantial risk of incurring double, multiple, or otherwise inconsistent obligations by reason of his claimed interest. If he has not been so joined, the court shall order that he be made a party. If he should join as a plaintiff but refuses to do so, he may be made a defendant, or, in a proper case, an involuntary plaintiff.

(b) Determination by Court Whenever Joinder Not Feasible. If a person as described in subdivision (a)(1)-(2) of this rule cannot be made a party, the court shall determine whether in equity and good conscience the action should proceed among the parties before it, or should be dismissed, the absent person being thus regarded as indispensable. The factors to be considered by the court include: (1) to what extent a judgment rendered in the person's absence might be prejudicial to him or those already parties; (2) the extent to which, by protective provisions in the judgment, by the shaping of relief, or other measures, the prejudice can be lessened or avoided; (3) whether a judgment rendered in the person's absence will be adequate; and (4) whether the plaintiff will have an adequate remedy if the action is dismissed for nonjoinder.

(c) Pleading Reasons for Nonjoinder. A pleading asserting a claim for relief shall state the names, if known to the pleader, of any persons as described in subdivision (a)(1)–(2) of this rule who are not joined, and the reasons why they are not joined.

(d) Exception of Class Actions. This rule is subject to the provisions of Rule 23.

Rule 20. Permissive Joinder of Parties

(a) Permissive Joinder. All persons may join in one action as plaintiffs if they assert any right to relief jointly, severally, or in the alternative in respect of or arising out of the same transaction, occurrence, or series of transactions or occurrences and if any question of law or fact common to all these persons will arise in the action. All persons may be joined in one action as defendants if there is asserted against them jointly, severally, or in the alternative, any right to relief in respect of or arising out of the same transaction, occurrence, or series of transactions or occurrences, and if any question of law or fact common to all defendants will arise in the action. A plaintiff or defendant need not be interested in obtaining or defending against all the relief demanded. Judgment

may be given for one or more of the plaintiffs according to their respective rights to relief, and against one or more defendants according to their respective liabilities.

(b) Separate Trials. The court may make such orders as will prevent a party from being embarrassed, delayed, or put to expense by the inclusion of a party against whom he asserts no claim and who asserts no claim against him, and may order separate trials or make other orders to prevent delay or prejudice.

Rule 21. Misjoinder and Nonjoinder of Parties

Misjoinder of parties is not ground for dismissal of an action. Parties may be dropped or added by order of the court on motion of any party or on its own initiative at any stage of the action and on such terms as are just. Any claim against a party may be severed and proceeded with separately.

Rule 22. Reserved

Rule 23. Class Actions

(a) Prerequisites to a Class Action. One or more members of a class may sue or be sued as representative parties on behalf of all only if (1) the class is so numerous that joinder of all members is impracticable, (2) there are questions of law or fact common to the class, (3) the claims or defenses of the representative parties are typical of the claims or defenses of the class, and (4) the representative parties will fairly and adequately protect the interests of the class.

(b) Class Actions Maintainable. An action may be maintained as a class action if the prerequisites of subdivision (a) are satisfied, and in addition:

(1) the prosecution of separate actions by or against individual members of the class would create a risk of (A) inconsistent or varying adjudications with respect to individual members of the class which would establish incompatible standards of conduct for the party opposing the class, or (B) adjudications with respect to individual members of the class which would as a practical matter be dispositive of the interests of the other members not parties to the adjudications or substantially impair or impede their ability to protect their interests; or

(2) the party opposing the class has acted or refused to act on grounds generally applicable to the class, thereby making appropriate final injunctive relief or corresponding declaratory relief with respect to the class as a whole; or

(3) the court finds that the questions of law or fact common to the members of the class predominate over any questions affecting only individual members, and that a class action is superior to other available methods for the fair and efficient adjudication of the controversy. The matters pertinent to the findings include: (A) the interest of members of the class in individually controlling the prosecution or defense of separate actions; (B) the extent and nature of any litigation concerning the controversy already commenced by or against members of the class; (C) the desirability or undesirability of

concentrating the litigation of the claims in the particular forum; (D) the difficulties likely to be encountered in the management of a class action.

(c) Determination by Order Whether Class Action To Be Maintained-Notice-JudgmentActions Conducted Partially as Class Actions.

(1) As soon as practicable after the commencement of an action brought as a class action, the court shall determine by order whether it is to be so maintained. An order under this subdivision may be conditional, and may be altered or amended before the decision on the merits.

(2) In any class action maintained under subdivision (b)(3) of this rule, the court shall direct to the members of the class the best notice practicable under the circumstances, including individual notice to all members who can be identified through reasonable effort. The notice shall advise each member that (A) the court will exclude him from the class if he so requests by a specified date; (B) the judgment, whether favorable or not, will include all members who do not request exclusion; and (C) any member who does not request exclusion may, if he desires, enter an appearance through his counsel.

(3) The judgment in an action maintained as a class action under subdivision (b)(1) or (b)(2) of this rule, whether or not favorable to the class, shall include and describe those whom the court finds to be members of the class. The judgment in an action maintained as a class action under subdivision (b)(3) of this rule, whether or not favorable to the class, shall include and specify or describe those to whom the notice provided in subdivision (c)(2) of this rule was directed, and who have not requested exclusion, and whom the court finds to be members of the class.

(4) When appropriate (A) an action may be brought or maintained as a class action with respect to particular issues, or (B) a class may be divided into subclasses and each subclass treated as a class, and the provisions of this rule shall then be construed and applied accordingly.

(d) Orders in Conduct of Actions. In the conduct of actions to which this rule applies, the court may make appropriate orders: (1) determining the course of proceedings or prescribing measures to prevent undue repetition or complication in the presentation of evidence or argument; (2) requiring, for the protection of the members of the class or otherwise for the fair conduct of the action, that notice be given in such manner as the court may direct to some or all of the members of any step in the action, or of the proposed extent of the judgment, or of the opportunity of members to signify whether they consider the representation fair and adequate, to intervene and present claims or defenses, or otherwise to come into the action; (3) imposing conditions on the representative parties or on intervenors; (4) requiring that the pleadings be amended to eliminate therefrom allegations as to representation of absent persons, and that the action proceed accordingly; (5) dealing with similar procedural matters.

The orders may be combined with an order under Rule 16(b), and may be altered or amended as may be desirable from time to time.

(e) Dismissal or Compromise. A class action shall not be dismissed or compromised without the approval of the court, and notice of the proposed dismissal or compromise shall be given to all members of the class in such manner as the court directs.

Rule 23.1. Actions Relating to Unincorporated Associations

An action brought by or against the members of an unincorporated association as a class by naming certain members as representative parties may be maintained only if it appears that the representative parties will fairly and adequately protect the interests of the association and its members. In the conduct of the action the court may make appropriate orders corresponding with those described in Rule 23(d), and the procedure for dismissal or compromise of the action shall correspond with that provided in Rule 23(e).

Rule 24. Intervention

(a) Intervention of Right. Upon timely application anyone shall be permitted to intervene in an action: (1) when a statute of the United States confers an unconditional right to intervene; or (2) when the applicant claims an interest relating to the property or transaction which is the subject of the action and he is so situated that the disposition of the action may as a practical matter impair or impede his ability to protect that interest, unless the applicant's interest is adequately represented by existing parties.

(b) Permissive Intervention. Upon timely application anyone may be permitted to intervene in an action: (1) when a statute of the United States confers a conditional right to intervene; or (2) when an applicant's claim or defense and the main action have a question of law or fact in common. When a party to an action relies for ground of claim or defense upon any statute or executive order administered by a federal governmental officer or agency or upon any regulation, order, requirement, or agreement issued or made pursuant to the statute or executive order, the officer or agency upon timely application 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.

(c) Procedure. A person desiring to intervene shall serve a motion to intervene upon the parties as provided in Rule 5. The motion shall state the grounds therefor and shall be accompanied by a pleading setting forth the claim or defense for which intervention is sought. The same procedure shall be followed when a statute of the United States gives a right to inter

vene.

PRACTICE COMMENT

To provide information to assist a judge in determing whether there is reason for disqualification upon

the grounds of a financial interest, under 28 U.S.C. $455, a completed "Disclosure Statement" form, available upon request from the office of the clerk, must be filed by certain corporations, trade associations, and others appearing as parties, intervenors, or amicus curiae. A copy of the "Disclosure Statement" form is shown in Form 13 of the Appendix of Forms.

Rule 25. Substitution of Parties

(a) Death.

(1) If a party dies and the claim is not thereby extinguished, the court may order substitution of the proper parties. The motion for substitution may be made by any party or by the successors or representatives of the deceased party and shall be served on the parties as provided in Rule 5 and upon the persons not parties in the manner provided in Rule 4 for the service of a summons. Unless the motion for substitution is made not later than 90 days after the death is suggested upon the record by service of a statement of the fact of the death as provided herein for the service of the motion, the action shall be dismissed as to the deceased party.

(2) In the event of the death of one or more of the plaintiffs or of one or more of the defendants in an action in which the right sought to be enforced survives only to the surviving plaintiffs or only against the surviving defendants, the action does not abate. The death shall be suggested upon the record and the action shall proceed in favor of or against the surviving parties.

(b) Incompetency. If a party becomes incompetent, the court upon motion served as provided in subdivision (a) of this rule may allow the action to be continued by or against his representative.

(c) Transfer of Interest. In case of any transfer of interest, the action may be continued by or against the original party, unless the court upon motion directs the person to whom the interest is transferred to be substituted in the action or joined with the original party. Service of the motion shall be made as provided in subdivision (a) of this rule.

(d) Public Officers-Death or Separation From Office.

(1) When a public officer is a party to an action in his official capacity and during its pendency dies, resigns, or otherwise ceases to hold office, the action does not abate and his successor is automatically substituted as a party. Proceedings following the substitution shall be in the name of the substituted party, but any misnomer not affecting the substantial rights of the parties shall be disregarded. An order of substitution may be entered at any time, but the omission to enter such an order shall not affect the substitution.

(2) When a public officer sues or is sued in his official capacity, he may be described as a party by his official title rather than by name; but the court may require his name to be added. TITLE V-DEPOSITIONS AND DISCOVERY Rule 26. General Provisions Governing Discovery

(a) Discovery Methods. Parties may obtain discovery by one or more of the following meth

ods: depositions upon oral examination or written questions; written interrogatories; production of documents or things or permission to enter upon land or other property for inspection and other purposes; physical and mental examinations; and requests for admission. Unless the court orders otherwise under subdivision (c) of this rule, the frequency of use of these methods is not limited.

(b) Scope of Discovery. Unless otherwise limited by order of the court as prescribed by these rules, the scope of discovery is as follows:

(1) In General. Parties may obtain discovery 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 party seeking discovery 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 any discoverable matter. It is not ground for objection that the information sought will be inadmissible at the trial if the information sought appears reasonably calculated to lead to the discovery of admissible evidence.

(2) Insurance Agreements. A party may obtain discovery of the existence and contents of any insurance agreement under which any person carrying on an insurance business may be liable to satisfy part or all of a judgment which may be entered in the action or to indemnify or reimburse for payments made to satisfy the judgment. Information concerning the insurance agreement is not by reason of disclosure admissible in evidence at trial. For purposes of this paragraph, an application for insurance shall not be treated as part of an insurance agreement.

(3) Trial Preparation-Materials. Subject to the provisions of paragraph (4) of this subdivision (b), a party may obtain discovery of documents and tangible things otherwise discoverable under paragraph (1) of this subdivision (b) and prepared in anticipation of litigation or for trial by or for another party or by or for that other party's representative (including his attorney, consultant, surety, indemnitor, insurer, or agent) only upon a showing that the party seeking discovery has substantial need of the materials in the preparation of his case and that he is unable without undue hardship to obtain the substantial equivalent of the materials by other means. In ordering discovery of such materials when the required showing has been made, the court shall protect against disclosure of the mental impressions, conclusions, opinions, or legal theories of an attorney or other representative of a party concerning the litigation.

A party may obtain without the required showing a statement concerning the action or its subject matter previously made by that party. Upon request, a person not a party may obtain without the required showing a statement concerning the action or its subject matter previously made by that person. If the request is refused, the person may move for a
