opinion: Chief Justice Rehnquist
  delivered the opinion of the Court.
  A group of white firefighters sued the city of Birmingham, Alabama (City), and the Jefferson County Personnel Board (Board) alleging that they were being denied promotions in favor of less qualified black firefighters. They claimed that the City and the Board were making promotion decisions on the basis of race in reliance on certain consent decrees, and that these decisions constituted impermissible racial discrimination in violation of the Constitution and federal statutes. The District Court held that the white firefighters were precluded from challenging employment decisions taken pursuant to the decrees, even though these firefighters had not been parties to the proceedings in which the decrees were entered. We think this holding contravenes the general rule that a person cannot be deprived of his legal rights in a proceeding to which he is not a party.
  The litigation in which the consent decrees were entered began in 1974, when the Ensley Branch of the National Association for the Advancement of Colored People and seven black individuals filed separate class-action complaints against the City and the Board. They alleged that both had engaged in racially discriminatory hiring and promotion practices in various public service jobs in violation of Title VII of the Civil Rights Act of 1964, 42 U. S. C. §2000e et seq., and other federal law. After a bench trial on some issues, but before judgment, the parties entered into two consent decrees, one between the black individuals and the City and the other between them and the Board. These proposed decrees set forth an extensive remedial scheme, including long-term and interim annual goals for the hiring of blacks as firefighters. The decrees also provided for goals for promotion of blacks within the fire department.
  The District Court entered an order provisionally approving the decrees and directing publication of notice of the upcoming fairness hearings. App. 694-696. Notice of the hearings, with a reference to the general nature of the decrees, was published in two local newspapers. At that hearing, the Birmingham Firefighters Association (BFA) appeared and filed objections as amicus curiae. After the hearing, but before final approval of the decrees, the BFA and two of its members also moved to intervene on the ground that the decrees would adversely affect their rights. The District Court denied the motions as untimely and approved the decrees. United States v. Jefferson County, 28 FEP Cases 1834 (ND Ala. 1981). Seven white firefighters, all members of the BFA, then filed a complaint against the City and the Board seeking injunctive relief against enforcement of the decrees. The seven argued that the decrees would operate to illegally discriminate against them; the District Court denied relief. App. to Pet. for Cert. 37a.
  Both the denial of intervention and the denial of injunctive relief were affirmed on appeal. United States v. Jefferson County, 720 F. 2d 1511 (CA11 1983). The District Court had not abused its discretion in refusing to let the BFA intervene, thought the Eleventh Circuit, in part because the firefighters could “institut[e] an independent Title VII suit, asserting specific violations of their rights.” Id., at 1518. And, for the same reason, petitioners had not adequately shown the potential for irreparable harm from the operation of the decrees necessary to obtain injunctive relief. Id., at 1520.
  A new group of white firefighters, the Wilks respondents, then brought suit against the City and the Board in District Court. They too alleged that, because of their race, they were being denied promotions in favor of less qualified blacks in violation of federal law. The Board and the City admitted to making race-conscious employment decisions, but argued that the decisions were unassailable because they were made pursuant to the consent decrees. A group of black individuals, the Martin petitioners, were allowed to intervene in their individual capacities to defend the decrees.
  The defendants moved to dismiss the reverse discrimination cases as impermissible collateral attacks on the consent decrees. The District Court denied the motions, ruling that the decrees would provide a defense to claims of discrimination for employment decisions “mandated” by the decrees, leaving the principal issue for trial whether the challenged promotions were indeed required by the decrees. App. 237-239, 250. After trial the District Court granted the motion to dismiss. App. to Pet. for Cert. 67a. The court concluded that “if in fact the City was required to [make promotions of blacks] by the consent decree, then they would not be guilty of [illegal] racial discrimination” and that the defendants had “established] that the promotions of the black indivictuals . . . were in fact required by the terms of the consent decree.” Id., at 28a.
  On appeal, the Eleventh Circuit reversed. It held that, “[bjecause . . . [the Wilks respondents] were neither parties nor privies to the consent decrees, . . . their independent claims of unlawful discrimination are not precluded.” In re Birmingham Reverse Discrimination Employment Litigation, 833 F. 2d 1492, 1498 (1987). The court explicitly rejected the doctrine of “impermissible collateral attack” espoused by other Courts of Appeals to immunize parties to a consent decree from charges of discrimination by nonparties for actions taken pursuant to the decree. Ibid. Although it recognized a “strong public policy in favor of voluntary affirmative action plans,” the panel acknowledged that this interest “must yield to the policy against requiring third parties to submit to bargains in which their interests were either ignored or sacrificed.” Ibid. The court remanded the case for trial of the discrimination claims, suggesting that the operative law for judging the consent decrees was that governing voluntary affirmative-action plans. Id., at 1497.
  We granted certiorari, 487 U. S. 1204 (1988), and now affirm the Eleventh Circuit’s judgment. All agree that “[i]t is a principle of general application in Anglo-American jurisprudence that one is not bound by a judgment in personam in a litigation in which he is not designated as a party or to which he has not been made a party by service of process.” Hansberry v. Lee, 311 U. S. 32, 40 (1940). See, e. g., Parklane Hosiery Co. v. Shore, 439 U. S. 322, 327, n. 7 (1979); Blonder-Tongue Laboratories, Inc. v. University Foundation, 402 U. S. 313, 328-329 (1971); Zenith Radio Corp. v. Hazeltine Research, Inc., 395 U. S. 100, 110 (1969). This rule is part of our “deep-rooted historic tradition that everyone should have his own day in court.” 18 C. Wright, A. Miller, & E. Cooper, Federal Practice and Procedure §4449, p. 417 (1981) (hereafter 18 Wright). A judgment or decree among parties to a lawsuit resolves issues as among them, but it does not conclude the rights of strangers to those proceedings.
  Petitioners argue that, because respondents failed to timely intervene in the initial proceedings, their current challenge to actions taken under the consent decree constitutes an impermissible “collateral attack.” They argue that respondents were aware that the underlying suit might affect them, and if they chose to pass up an opportunity to intervene, they should not be permitted to later litigate the issues in a new action. The position has sufficient appeal to have commanded' the approval of the great majority of the Federal Courts of Appeals, but we agree with the contrary view expressed by the Court of Appeals for the Eleventh Circuit in these cases.
  We begin with the words of Justice Brandéis in Chase National Bank v. Norwalk, 291 U. S. 431 (1934):
  “The law does not impose upon any person absolutely entitled to a hearing the burden of voluntary intervention in a suit to which he is a stranger. . . . Unless duly summoned to appear in a legal proceeding, a person not a privy may rest assured that a judgment recovered therein will not affect his legal rights.” Id. at 441.
  While these words were written before the adoption of the Federal Rules of Civil Procedure, we think the Rules incorporate the same principle; a party seeking a judgment binding on another cannot obligate that person to intervene; he must be joined. See Hazeltine, supra, at 110 (judgment against Hazeltine vacated because it was not named as a party or served, even though as the parent corporation of one of the parties it clearly knew of the claim against it and had made a special appearance to contest jurisdiction). Against the background of permissive intervention set forth in Chase National Bank, the drafters cast Rule 24, governing intervention, in permissive terms. See Fed. Rule Civ. Proc. 24(a) (intervention as of right) (“Upon timely application anyone shall be permitted to intervene”); Fed. Rule Civ. Proc. 24(b) (permissive intervention) (“Upon timely application anyone may be permitted to intervene”). They determined that the concern for finality and completeness of judgments would be “better [served] by mandatory joinder procedures.” 18 Wright §4452, p. 453. Accordingly, Rule 19(a) provides for mandatory joinder in circumstances where a judgment rendered in the absence of a person may “leave . . . persons already parties subject to a substantial risk of incurring . . . inconsistent obligations. . . .” Rule 19(b) sets forth the factors to be considered by a court in deciding whether to allow an action to proceed in the absence of an interested party.
  Joinder as a party, rather than knowledge of a lawsuit and an opportunity to intervene, is the method by which potential parties are subjected to the jurisdiction of the court and bound by a judgment or decree. The parties to a lawsuit presumably know better than anyone else the nature and scope of relief sought in the action, and at whose expense such relief might be granted. It makes sense, therefore, to place on them a burden of bringing in additional parties where such a step is indicated, rather than placing on potential additional parties a duty to intervene when they acquire knowledge of the lawsuit. The linchpin of the “impermissible collateral attack” doctrine — the attribution of preclusive effect to a failure to intervene — is therefore quite inconsistent with Rule 19 and Rule 24.
  Petitioners argue that our decisions in Penn-Central Merger and N & W Inclusion Cases, 389 U. S. 486 (1968), and Provident Tradesmens Bank & Trust Co. v. Patterson, 390 U. S. 102 (1968), suggest an opposite result. The Penn-Central litigation took place in a special statutory framework enacted by Congress to allow reorganization of a huge railway system. Primary jurisdiction was in the Interstate Commerce Commission, with very restricted review in a statutory three-judge District Court. Review proceedings were channeled to the District Court for the Southern District of New York, and proceedings in other District Courts were stayed. The District Court upheld the decision of the Interstate Commerce Commission in both the merger and the inclusion proceedings, and the parties to that proceeding appealed to this Court. Certain Pennsylvania litigants had sued in the District Court for the Middle District of Pennsylvania to set aside the Commission’s order, and this action was stayed pending the decision in the District Court for the Southern District of New York. We held that the borough of Moosic, one of the Pennsylvania litigants, could not challenge the Commission’s approval of the merger and inclusion in the Pennsylvania District Court, pointing out the unusual nationwide character of the action and saying “[i]n these circumstances, it would be senseless to permit parties seeking to challenge the merger and the inclusion orders to bring numerous suits in many different district courts.” 389 U. S., at 505, n. 4.
  We do not think that this holding in Penn Central, based as it was upon the extraordinary nature of the proceedings challenging the merger of giant railroads and not even mentioning Rule 19 or Rule 24, affords a guide to the interpretation of the rules relating to joinder and intervention in ordinary civil actions in a district court.
  Petitioners also rely on our decision in Provident Bank, swpra, as authority for the view which they espouse. In that case we discussed Rule 19 shortly after parts of it had been substantially revised, but we expressly left open the question whether preclusive effect might be attributed to a failure to intervene. 390 U. S., at 114-115.
  Petitioners contend that a different result should be reached because the need to join affected parties will be burdensome and ultimately discouraging to civil rights' litigation. Potential adverse claimants may be numerous and difficult to identify; if they are not joined, the possibility for inconsistent judgments exists. Judicial resources will be needlessly consumed in relitigation of the same question.
  Even if we were wholly persuaded by these arguments as a matter of policy, acceptance of them would require a rewriting rather than an interpretation of the relevant Rules. But we are not persuaded that their acceptance would lead to a more satisfactory method of handling cases like these. It must be remembered that the alternatives are a duty to intervene based on knowledge, on the one hand, and some form of joinder, as the Rules presently provide, on the other. No one can seriously contend that an employer might successfully defend against a Title VII claim by one group of employees on the ground that its actions were required by an earlier decree entered in a suit brought against it by another, if the later group did not have adequate notice or knowledge of the earlier suit.
  The difficulties petitioners foresee in identifying those who could be adversely affected by a decree granting broad remedial relief are undoubtedly present, but they arise from the nature of the relief sought and not because of any choice between mandatory intervention and joinder. Rule 19’s provisions for joining interested parties are designed to accommodate the sort of complexities that may arise from a decree affecting numerous people in various ways. We doubt that a mandatory intervention rule would be any less awkward. As mentioned, plaintiffs who seek the aid of the courts to alter existing employment policies, or the employer who might be subject to conflicting decrees, are best able to bear the burden of designating those who would be adversely affected if plaintiffs prevail; these parties will generally have a better understanding of the scope of likely relief than employees who are not named but might be affected. Petitioners’ alternative does not eliminate the need for, or difficulty of, identifying persons who, because of their interests, should be included in a lawsuit. It merely shifts that responsibility to less able shoulders.
  Nor do we think that the system of joinder called for by the Rules is likely to produce more relitigation of issues than the converse rule. The breadth of a lawsuit and concomitant relief may be at least partially shaped in advance through Rule 19 to avoid needless clashes with future litigation. And even under a regime of mandatory intervention, parties who did not have adequate knowledge of the suit would relitigate issues. Additional questions about the adequacy and timeliness of knowledge would inevitably crop up. We think that the system of joinder presently contemplated by the Rules best serves the many interests involved in the run of litigated cases, including cases like the present ones.
  Petitioners also urge that the congressional policy favoring voluntary settlement of employment discrimination claims, referred to in cases such as Carson v. American Brands, Inc., 450 U. S. 79 (1981), also supports the “impermissible collateral attack” doctrine. But once again it is essential to note just what is meant by “voluntary settlement. ” A voluntary settlement in the form of a consent decree between one group of employees and their employer cannot possibly “settle,” voluntarily or otherwise, the conflicting claims of another group of employees who do not join in the agreement. This is true even if the second group of employees is a party to the litigation:
  “[P]arties who choose to resolve litigation through settlement may not dispose of the claims of a third party . . . without that party’s agreement. A court’s approval of a consent decree between some of the parties therefore cannot dispose of the valid claims of nonconsenting intervenors.” Firefighters v. Cleveland, 478 U. S. 501, 529 (1986).
  Insofar as the argument is bottomed on the idea that it may be easier to settle claims among a disparate group of affected persons if they are all before the court, joinder bids fair to accomplish that result, as well as a regime of mandatory intervention.
  For the foregoing reasons we affirm the decision of the Court of Appeals for the Eleventh Circuit. That court remanded the case for trial of the reverse discrimination claims. Birmingham Reverse Discrimination, 833 F. 2d, at 1500-1502. Petitioners point to language in the District Court’s findings of fact and conclusions of law which suggests that respondents will not prevail on the merits. We agree with the view of the Court of Appeals, however, that the proceedings in the District Court may have been affected by the mistaken view that respondents’ claims on the merits were barred to the extent they were inconsistent with the consent decree.
  Affirmed.
  Judge Anderson, dissenting, “agreefd] with the opinion for the court that these plaintiffs [the Wilks respondents] were not parties to the prior litigation which resulted in the consent decree, and that the instant plaintiffs are not bound by the consent decree and should be free on remand to challenge the consent decree prospectively and test its validity against the recent Supreme Court precedent.” In re Birmingham Reverse Discrimination Employment Litigation, 833 F. 2d, at 1503. He distinguished, however, between claims for prospective relief and claims for backpay, the latter being barred, in his opinion, by the City’s good-faith reliance on the decrees. Id., at 1502.
  We have recognized an exception to the general rule when, in certain limited circumstances, a person, although not a party, has his interests adequately represented by someone with the same interests who is a party. See Hansberry v. Lee, 311 U. S. 32, 41-42 (1940) (“class” or “representative” suits); Fed. Rule Civ. Proc. 23 (same); Montana v. United States, 440 U. S. 147, 154-155 (1979) (control of litigation on behalf of one of the parties in the litigation). Additionally, where a special remedial scheme exists expressly foreclosing successive litigation by nonlitigants, as for example in bankruptcy or probate, legal proceedings may terminate preexisting rights if the scheme is otherwise consistent with due process. See NLRB v. Bildisco & Bildisco, 465 U. S. 513, 529-530, n. 10 (1984) (“[Pjroof of claim must be presented to the Bankruptcy Court ... or be lost”); Tulsa Professional Collection Services, Inc. v. Pope, 485 U. S. 478, (1988) (nonclaim statute terminating unsubmitted claims against the estate). Neither of these exceptions, however, applies in these cases.
  For a sampling of cases from the Circuits applying the “impermissible collateral attack” rule or its functional equivalent, see, e. g., Striff v. Mason, 849 F. 2d 240, 245 (CA6 1988); Marino v. Ortiz, 806 F. 2d 1144, 1146-1147 (CA2 1986), aff’d by an equally divided Court, 484 U. S. 301 (1988); Thaggard v. Jackson, 687 F. 2d 66, 68-69 (CA5 1982), cert. denied sub nom. Ashley v. City of Jackson, 464 U. S. 900 (1983) (REHNQUIST, J.. joined by Brennan, J., dissenting); Stotts v. Memphis Fire Dept., 679 F. 2d 541, 558 (CA6 1982), rev’d on other grounds sub nom. Firefighters v. Stotts, 467 U. S. 561 (1984); Dennison v. Los Angeles Dept. of Water & Power, 658 F. 2d 694, 696 (CA9 1981); Goins v. Bethlehem Steel Corp., 657 F. 2d 62, 64 (CA4 1981), cert. denied, 455 U. S. 940 (1982); Society Hill Civic Assn. v. Harris, 632 F. 2d 1045, 1052 (CA3 1980). Apart from the instant one, the only Circuit decision of which we are aware that would generally allow collateral attacks on consent decrees by nonparties is Dunn v. Carey, 808 F. 2d 555, 559-560 (CA7 1986).
  Rule 19(a) provides:
  “A person who is subject to service of process and whose joinder will not deprive the court of jurisdiction . . . shall be joined as a party in the action if (1) in the person's absence complete relief cannot be accorded among those already parties, or (2) the person claims an interest relating to the subject of the action and is so situated that the disposition of the action in the person’s absence may (i) as a practical matter impair or impede the perso>i’s ability to protect that interest or (ii) leave any of the persons already parties subject to a substantial risk of incurring double, multiple, or otherwise inconsistent obligations by reason of the claimed interest. If the person has not been so joined, the court shall order that the person be made a party. If the person should join as a plaintiff but refuses to do so, the person may be made a defendant, or, in a proper ease, an involuntary plaintiff. If the joined party objects to venue and joinder of that party would render the venue of the action improper, that party shall be dismissed from the action.” (Emphasis added.)
  Rule 19(b) provides:
  “If a person . . . 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: first, to what extent a judgment rendered in the person’s absence might be prejudicial to the person or those already parties; second, 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; third, whether a judgment rendered in the person’s absence will be adequate; fourth, whether the plaintiff will have an adequate remedy if the action is dismissed for nonjoinder.”
  The dissent argues, on the one hand, that respondents have not been “bound” by the decree but, rather, that they are only suffering practical adverse effects from the consent decree. Post, at 770-772. On the other hand, the dissent characterizes respondents’ suit not as an assertion of their own independent rights, but as a collateral attack on the consent decrees which, it is said, can only proceed on very limited grounds. Post, at 783-787. Respondents in their suit have alleged that they are being racially discriminated against by their employer in violation of Title VII: either the fact that the disputed employment decisions are being made pursuant to a consent decree is a defense to respondents’ Title VII claims or it is not. If it is a defense to challenges to employment practices which would otherwise violate Title VII, it is very difficult to see why respondents are not being “bound” by the decree.
