delivered the opinion of the Court.
This case presents the question whether federal courts have statutory or inherent power to tax attorney’s fees directly against counsel who have abused the processes of the courts.
I
In June 1975, two former employees and one unsuccessful job applicant brought a civil rights class action against petitioner Roadway Express, Inc. (Roadway). The complaint filed in the United States District Court for the Western District of Louisiana alleged that Roadway’s employment policies discriminated on the basis of race, and asked for equitable relief.1
Counsel for the plaintiffs — Robert E. Piper, Jr., Frank E. Brown, Jr., and Bobby Stromile — are the respondents in the present case. In September 1975, respondents served interrogatories on Roadway. Having secured an extension from the District Court, Roadway answered the interrogatories on January 5, 1976, and served its own set of interrogatories at the same time. Thereafter, however, the litigation was stalled by respondents’ uncooperative behavior.
*755On April 13, 1976, Roadway moved for an order compelling answers to its interrogatories. The motion was set for argument on the morning of April 21, but counsel for the plaintiffs did not appear. They did attend a rescheduled hearing that afternoon, and the Magistrate ordered that the interrogatories be answered by May 24. Respondents ignored that deadline and, in fact, never answered the interrogatories. Roadway also served notice in April that it would take depositions from all three plaintiffs in early May. One of the plaintiffs did not appear on the appointed days, however, and he never was deposed.
The respondents showed no greater respect for the orders of the District Court than for the requests of their adversaries. On April 7, the court instructed counsel for both sides to file briefs evaluating the impact of a recent decision in a related ease. Although respondents’ brief was due within 10 days, nothing arrived for six weeks. On May 19, the District Court gave respondents 10 additional days to file a brief or face dismissal of the action. No brief was ever submitted.
On June 14, Roadway moved to dismiss the suit under Federal Rule of Civil Procedure 37.2 Roadway also requested an award of attorney’s fees and court costs. On June 30, the District Court heard argument and dismissed the action with prejudice. A second hearing, limited to the question of costs and attorney’s fees, was held in October 1976.
The District Court’s opinion sharply criticized the respondents for their “deliberate inaction” in handling the case. Monk v. Roadway Express, Inc., 73 F. R .D. 411, 417 (1977). Observing that respondents apparently had not advised their *756clients that the suit was a class action, id., at 414, 417, the court concluded that the three lawyers “improvidently enlarged and inadequately prosecuted” the action, id., at 417. As a sanction, the court ordered them to pay Roadway’s costs and attorney’s fees for the entire lawsuit. The total assessment exceeded $17,000. Monk v. Roadway Express, Inc., 599 F. 2d 1378, 1381 (CA5 1979).
The District Court found justification for its ruling in the confluence of several statutes. The civil rights statutes allow the prevailing party to recover attorney’s fees “as part of the costs” of litigation. See 42 U. S. C. §§ 1988, 2000e-5 (k). And 28 TJ. S. C. § 1927 permits a court to tax the excess “costs” of a proceeding against a lawyer “who so multiplies the proceedings ... as to increase costs unreasonably and vexatiously. ...”3 Read together, the District Court concluded, the statutes authorize the assessment of costs and attorney’s fees against respondents.
The United States Court of Appeals for the Fifth Circuit found no clear error in the ruling that respondents had violated § 1927. 599 F. 2d, at 1381. The appellate court held, however, that respondents were not liable for attorney’s fees. It rejected the District Court’s view that the civil rights statutes can be read into § 1927. The civil rights laws, the court wrote, “provide for attorneys’ fees awards against unsuccessful parties to a suit, and they focus on actions which are frivolous, unreasonable, and baseless. . . .” 599 F. 2d, at *7571383 (emphasis in original). In contrast, § 1927 deals only with attorney conduct and involves taxing costs against counsel. The Court of Appeals vacated the District Court’s order and remanded for recalculation of costs under § 1927. We granted certiorari, 444 U. S. 1012 (1980).
II
This case involves the problem of what sanctions may be imposed on lawyers who unreasonably extend court proceedings.4 Two specific provisions have been said to be controlling in this case: 28 U. S. C. § 1927, and Federal Rule of Civil Procedure 37. This opinion considers both provisions.
A
Section 1927 provides that lawyers who multiply court proceedings vexatiously may be assessed the excess “costs” they create. The provision, however, does not define the critical word. Only if “costs” includes attorney’s fees can § 1927 support the sanction in this case.
Courts generally have defined costs under § 1927 according to 28 U. S. C. § 1920, which enumerates the costs that ordinarily may be taxed to a losing party. E. g., United States v. Ross, 535 F. 2d 346, 350 (CA6 1976); Kiefel v. Las Vegas Hacienda, Inc., 404 F. 2d 1163, 1170 (CA7 1968), cert. denied sub nom. Hubbard v. Kiefel, 395 U. S. 908 (1969). *758Section 1920 lists clerk’s and marshal’s fees, court reporter charges, printing and witness fees, copying costs, interpreting costs, and the fees of court-appointed experts. Section 1920 also permits the assessment of the attorney “docket” fees set by 28 TJ. S. C. § 1923. In this case, that fee is $20. 28 TJ. S. C. § 1923 (a).
Roadway insists, however, that its recovery should not be restricted to the costs listed in § 1920. It argues that since courts look to § 1920 to determine the costs taxable under § 1927, they should be equally free to define costs according to other statutes that may be involved in a lawsuit. Roadway emphasizes that the civil rights statutes allow the award of attorney’s fees “as part of the costs” of the litigation. 42 TJ. S. C. § 2000e-5 (k); 42 TJ. S. C. § 1988.5 Accordingly, Roadway asks that we reinstate the District Court’s award. This superficially appealing argument cannot survive careful consideration.
*7591
Congress enacted the first version of § 1927 in 1813. It was drafted by a Senate Committee appointed “to inquire what Legislative provision is necessary to prevent multiplicity of suits or processes, where a single suit or process might suffice. . . .” 26 Annals of Cong. 29 (1813). The resulting legislation provided in part that any person who “multiplied the proceedings in any cause ... so as to increase costs unreasonably and vexatiously” could be held liable for “any excess of costs so incurred.” Act of July 22, 1813, 3 Stat. 21. The sparse legislative history makes this provision difficult to interpret.6
In construing “costs,” however, we may look to the contemporaneous understanding of the term. Cf. Gilbert v. United States, 370 U. S. 650, 655 (1962). In 1796 the Court decided Arcambel v. Wiseman, 3 Dali. 306. That ruling overturned an award of counsel fees on the ground that “[t]he general practice of the United States is in op [position to it.” Ibid. Thus, the Court recognized the “American rule” that attorney’s fees ordinarily are not among the costs that a winning party may recover. See Fleischmann Distilling Corp. v. Maier Brewing Co., 386 U. S. 714, 717-718 (1967). We may assume that Congress followed that rule when it approved the 1813 Act.
Congress returned to the problems of the federal courts in 1853, when it approved a comprehensive measure setting the fees and costs for all federal actions. Act of Feb. 26, 1853, 10 Stat. 162; see Alyeska Pipeline Co. v. Wilderness Society, 421 U. S. 240, 251-253 (1975). Some of those provisions survive, largely intact, in 28 U. S. C. §§ 1920 and 1923. See *76010 Stat. 161-162, 168. The 1853 statute also substantially-re-enacted the earlier provision that allows lawyers who multiply legal proceedings to be taxed with the extra “costs” they generate. That provision, now codified as § 1927, has remained basically unchanged since 1853.7
This history suggests that § 1920 and § 1927 should be read together as part of the integrated statute approved in 1853. See Erlenbaugh v. United States, 409 U. S. 239, 243-244 (1972); 2A C. Sands, Sutherland on Statutory Construction § 51.03, p. 299 (4th ed. 1973). The 1853 Act specified the costs recoverable in federal litigation and also allowed the award of excess “costs” against counsel who vexatiously multiply litigation. The most reasonable construction is that the Act itself defined those costs that may be recovered from counsel. Congress, of course, may amend those provisions that derive from the 1853 Act.8 In the absence of express modification of those provisions by Congress, however, we should not look beyond the Act for the definition of costs under § 1927.
The available legislative material supports this view. Congress in 1853 prescribed taxable costs for the same reasons it authorized the assessment of costs against dilatory attorneys: “[T]o prevent abuses arising from ingenious constructions ... to discourage unnecessary prolixity, old useless forms, and the multiplication of proceedings, and the prosecutions of several suits which might better be joined in one.” *761H. R. Rep. No. 50, 32d Cong., 1st Sess., 6 (1852); see also Alyeska Pipeline Co. v. Wilderness Society, supra, at 251-253. Above all, Congress sought to standardize the treatment of costs in federal courts, to “make them uniform— make the law explicit and definite.” H. R. Rep. No. 50, supra, at 6. The sponsor of the legislation spoke of the need for “uniform rule[s],” Cong. Globe, 32d Cong., 2d Sess., App. 207 (1853) (Sen. Bradbury), while other Senators agreed that the legislation was designed to impose “uniformity,” id., at 584 (Sen. Bayard); see also id., at 589 (Sen. Geyer).
Roadway presses us to abandon the uniform approach of the 1853 Act. Because prevailing parties now may recover counsel fees in civil rights suits, Roadway argues that the statutes authorizing those recoveries should be read to modify § 1927. But Roadway offers no evidence that Congress intended to incorporate those attorney’s fee provisions into § 1927. Neither § 1988 nor § 2000e-5 (k) makes any mention of attorney liability for costs and fees. Roadway identifies nothing in the legislative records of those provisions that suggests that Congress meant to control the conduct of litigation.9 Without any evidence that Congress wished to alter the uniform structure established by the 1853 Act, we are reluctant to disrupt it. See Fleischmann Distilling Corp. v. Maier Brewing Co., supra, at 719-720.

The statutory interpretation proposed by Roadway not only runs counter to the apparent intent of Congress in 1813 and 1853, but also could introduce into the statute distinctions unrelated to its goal. Indeed, Roadway’s argument could result in virtually random application of § 1927 on the basis of other *762laws that do not address the problem of controlling abuses of judicial processes.
The fee provisions of the civil rights laws are acutely sensitive to the merits of an action and to antidiscrimination policy. Unlike § 1927, both § 1988 and § 2000e-5 (k) restrict recovery to prevailing parties. In addition, those provisions have been construed to treat plaintiffs and defendants somewhat differently. Prevailing plaintiffs in civil rights cases win fee awards unless “special circumstances would render such an award unjust,” Newman v. Piggie Park Enterprises, 390 U. S. 400, 402 (1968) (per curiam), but a prevailing defendant may be awarded counsel fees only when the plaintiff’s underlying claim is “frivolous, unreasonable, or groundless.” Christiansburg Garment Co. v. EEOC, 434 U. S. 412, 422 (1978). This distinction advances the congressional purpose to encourage suits by victims of discrimination while deterring frivolous litigation.
But § 1927 does not distinguish between winners and losers, or between plaintiffs and defendants. The statute is indifferent to the equities of a dispute and to the values advanced by the substantive law. It is concerned only with limiting the abuse of court processes. Dilatory practices of civil rights plaintiffs are as objectionable as those of defendants. In order to assess counsel fees against respondents under § 1927, the Court would have to adopt one of two alternatives. It could incorporate into § 1927 the normative considerations of the civil rights laws that are foreign to the 1813 enactment. Or the Court could select on an ad hoc basis those features of § 1988 and § 2000e-5 (k) that should be read into § 1927. The first course would alter fundamentally the nature of § 1927; the second would constitute standardless judicial lawmaking.
Moreover, Roadway’s statutory construction would create a two-tier system of attorney sanctions. A number of federal statutes permit the award of attorney’s fees. See Alyeska *763 Pipeline Co. v. Wilderness Society, 421 U. S., at 260, n. 33. Under Roadway's view of § 1927, lawyers in cases brought under those statutes would face stiffer penalties for prolonging litigation than would other attorneys. There is no persuasive justification for subjecting lawyers in different areas of practice to differing sanctions for dilatory conduct. A court’s processes may be as abused in a commercial case as in a civil rights action. Without an express indication of congressional intent, we must hesitate to reach the imaginative outcome urged by Roadway, particularly when a more plausible construction flows from the original enactments in 1813 and 1853. To avoid the arbitrary results of Roadway's argument, Commissioner v. Brown, 380 U. S. 563, 571 (1965), citing Helvering v. Hammel, 311 U. S. 504, 510-511 (1941), we must reject the claim that § 1988 and § 2000e-5 (k) may supplant the framework established by the 1853 Act.
B
Federal Rule of Civil Procedure 37 (b) authorizes sanctions for failure to comply with discovery orders. The District Court may bar the disobedient party from introducing certain evidence, or it may direct that certain facts shall be “taken to be established for the purposes of the action. ...” The Rule also permits the trial court to strike claims from the pleadings, and even to “dismiss the action ... or render a judgment by default against the disobedient party.” See National Hockey League v. Metropolitan Hockey Club, 427 U. S. 639 (1976) (per curiam); Heliums v. Powell, 184 U. S. App. D. C. 339, 566 F. 2d 231 (1977). Both parties and counsel may be held personally liable for expenses, “including attorney’s fees,” caused by the failure to comply with discovery orders.10 Rule 37 sanctions must be applied diligently *764both “to penalize those whose conduct may be deemed to warrant such a sanction, [and] to deter those who might be tempted to such conduct in the absence of such a deterrent.” National Hockey League v. Metropolitan Hockey Club, supra, at 643.
The respondents in this case never have complied with the District Court’s order that they answer Roadway’s interrogatories. That failure was the immediate ground for dismissing the case, 73 F. R. D., at 412, and it also exposed respondents and their clients to liability under Rule 37 (b) for the resulting costs and attorney’s fees. Indeed, Roadway’s motion for dismissal sought recovery of those expenses under Rule 37. On the remand of this action, the District Court will have the authority to act upon that request.
Ill
Roadway also contends that the District Court’s ruling was a proper exercise of the court’s inherent powers.11 The inherent powers of federal courts are those which “are necessary to the exercise of all others.”' United States v. Hudson, 7 Cranch 32, 34 (1812). The most prominent of these is the contempt sanction, “which a judge must have and exercise in protecting the due and orderly administration of justice and in maintaining the authority and dignity of the court. . . .” Cooke v. United States, 267 U. S. 517, 539 (1925); see 4 W. Blackstone, Commentaries *282-*285. Because inherent powers are shielded from direct democratic controls, they must be exercised with restraint and discretion. See Gompers v. Bucks Stove & Range Co., 221 U. S. 418, *765450-451 (1011); Green v. United States, 356 U. S. 165, 193-194 (1958) (Black, J., dissenting). There are ample grounds for recognizing, however, that in narrowly defined circumstances federal courts have inherent power to assess attorney’s fees against counsel.
In Link v. Wabash R. Co., 370 U. S. 626, 632 (1962), this Court recognized the “well-acknowledged” inherent power of a court to levy sanctions in response to abusive litigation practices. The trial court had dismissed an action for failure to prosecute. Mr. Justice Harlan wrote for the Court:
“The authority of a federal trial court to dismiss a plaintiff’s action with prejudice because of his failure to prosecute cannot seriously be doubted. The power to invoke this sanction is necessary in order to prevent undue delays in the disposition of pending cases and to avoid congestion in the calendars of the District Courts. The power is of ancient origin, having its roots in judgments of nonsuit and non prosequitur entered at common law, e. g., 3 Blackstone, Commentaries (1768), 295-296, and dismissals for want of prosecution of bills in equity, e. g., id., at 451.” Id., at 629-630 (footnote omitted).
The Court denied that Federal Rule of Civil Procedure 41 (b) limits a court’s power to dismiss for failure to prosecute to instances where a defendant moves for dismissal. The Court wrote: “The authority ... to dismiss sua sponte for lack of prosecution has generally been considered an 'inherent power,’ governed not by rule or statute but by the control necessarily vested in courts to manage their own affairs. . . .” 370 U. S., at 630. Since the assessment of counsel fees is a less severe sanction than outright dismissal, Link strongly supports Roadway’s contention here.
Of course, the general rule in federal courts is that a litigant cannot recover his counsel fees. See Alyeska Pipeline Co. v. Wilderness Society, 421 U. S., at 257. But that rule does *766not apply when the opposing party has acted in bad faith. In Alyeska, we acknowledged the “inherent power” of courts to
“assess attorneys’ fees for the 'willful disobedience of a court order ... as part of the fine to be levied on the defendant[,] Toledo Scale Co. v. Computing Scale Co., 261 U. S. 399, 426-428 (1923),’ Fleischmann Distilling Corp. v. Maier Brewing Co., supra, at 718; or when the losing party has 'acted in bad faith, vexatiously, wantonly, or for oppressive reasons . . . .’ F. D. Rich Co. [v. United States ex rel. Industrial Dumber Co.], 417 U. S. [116], at 129 [(1974)] (citing Vaughan v. Atkinson, 369 U. S. 527 (1962)).” Id., at 258-259.
The bad-faith exception for the award of attorney’s fees is not restricted to cases where the action is filed in bad faith. '"[B]ad faith’ may be found, not only in the actions that led to the lawsuit, but also in the conduct of the litigation.” Hall v. Cole, 412 U. S. 1, 15 (1973). See Browning Debenture Holders’ Comm. v. DASA Corp., 560 F. 2d 1078, 1088 (CA2 1977). This view coincides with the ruling in Link, supra, which approved judicial power to dismiss a case not because the substantive claim was without merit, but because the plaintiff failed to pursue the litigation.
The power of a court over members of its bar is at least as great as its authority over litigants.12 If a court may tax counsel fees against a party who has litigated in bad faith, it certainly may assess those expenses against counsel who willfully abuse judicial processes. See Renfrew, Discovery Sanctions: A Judicial Perspective, 67 Calif. L. Rev. 264, 268 *767(1979).13 Like other sanctions, attorney’s fees certainly should not be assessed lightly or without fair notice and an opportunity for a hearing on the record.14 But in a proper ease, such sanctions are within a court’s powers.
IV
We affirm the ruling of the Court of Appeals on § 1927. Since the District Court did not consider the costs and fees that' Roadway might recover under Rule 37, that question must be addressed on remand. Similarly, the trial court did not make a specific finding as to whether counsel’s conduct in this case constituted or was tantamount to bad faith, a finding that would have to precede any sanction under the court’s inherent powers. The case is remanded to the Court of *768Appeals with directions to return it to the District Court for proceedings consistent with this opinion.
So ordered.
