OPINION OF THE COURT
COWEN, Circuit Judge.The Commonwealth of Pennsylvania, the original plaintiff in this matter, appeals from the order of the district court awarding attorney’s fees against it pursuant to 42 U.S.C. § 1988 or, alternatively, pursuant to Federal Rule of Civil Procedure 41(b). Because the lawsuit filed by the Commonwealth was not frivolous, unreasonable, or without foundation and because the Commonwealth did not fail to prosecute its ease, we will reverse the award of attorney’s fees against the Commonwealth.
I. Factual and Procedural Background
In 1975, the Commonwealth of Pennsylvania (“Commonwealth”) filed suit under 42 U.S.C: §§ 1981 and 1983 against the City of Pittsburgh (“City”) alleging, inter alia, discrimination in the hiring of minority applicants by the Police Department of the City of Pittsburgh. Following a hearing the district court made findings that the City had virtually eliminated the hiring of minority applicants as police officers. The district court entered a preliminary injunction requiring the City to hire one white female, one African-American male, and one African-American female for every white male that it hired. The City did not appeal from the preliminary injunction order.
In 1977, the Fraternal Order of Police, an intervening defendant, moved to dissolve the injunction. The application was denied by the district court because the Fraternal Order of Police lacked standing. In 1984, a white male applicant who had continually applied for a position as a Pittsburgh police officer since 1975 moved to intervene in this *60action in order to challenge the preliminary injunction. The district court denied the application, and we affirmed the order of the district court. Finally, in 1990, Paul Clark, Richard Usner, Michael Benner, and Daniel Dulski (“intervening defendants”), white male applicants, filed two separate complaints against the City of Pittsburgh and its officials challenging the hiring system imposed by the preliminary injunction. The district court consolidated the eases thereby making these parties intervening defendants to the original suit between the Commonwealth and the City.
In March of 1991 the district court granted the intervening defendants’ motion to dissolve the injunction and denied the intervening defendants’ motion to dismiss for failure to prosecute. The Commonwealth appealed the dissolution of the injunction to this Court. We dismissed the appeal as moot when the district court granted partial summary judgment in favor of the intervening defendants on the claim of discrimination in the hiring of police officers.
The district court also granted intervening defendants’ petitions for attorney’s fees incurred in obtaining the dissolution of the injunction, assessing 75% of the fees against the plaintiff Commonwealth and 25% against the defendant City of Pittsburgh. In making this award of attorney’s fees, the district court realigned the parties. The intervening defendants were treated as plaintiffs and the plaintiff Commonwealth and defendant City were deemed defendants for the purpose of awarding fees under 42 U.S.C. § 1988. Commonwealth v. Flaherty, Nos. 75-162, 90-457, 90-629, slip op. at 15 (W.D.Pa. Sept. 9, 1991). The order granting the intervening defendants’ motion for summary judgment and denying their motion to dismiss the original complaint for failure of the Commonwealth to prosecute was affirmed on appeal. The appeal of the attorney’s fees award was dismissed because the fee award had not been quantified and therefore was not a final order. Commonwealth v. Flaherty, 983 F.2d 1267, 1277 (3d Cir.1993). Subsequently, the district court quantified the attorney’s fees requested by the intervening defendants at $80,000.00, and the Commonwealth was required to pay 75%, or $60,000.00. The City was ordered to pay 25%, or $20,000.00. Flaherty, slip op. at 3-4 (March 17, 1994). Although the City has entered an appearance in this appeal, it has not filed a brief nor sought oral argument. This appeal by the Commonwealth followed.
II. Discussion
A Award of Attorney’s Fees Under U.S.C. § 1988
The district court awarded $60,000.00 in attorney’s fees in favor of the intervening defendants and against the Commonwealth. This Court has previously stated that, “[w]e must defer to the district court’s fee determination unless it has erred legally, or the facts on which the determination rests are clearly erroneous.” Quiroga v. Hasbro, Inc., 934 F.2d 497, 502 (3d Cir.) (citations omitted), cert. denied, — U.S. -, 112 S.Ct. 376, 116 L.Ed.2d 327 (1991). We conclude that the district court erred as a matter of law in realigning the parties, thus failing to apply the rule that fees cannot be awarded against a plaintiff absent a finding that the suit was frivolous, unreasonable, or without foundation.
The general rule in the United States is that absent legislation to the contrary, litigants must bear their own attorney’s fees. See Alyeska Pipeline Service Co. v. Wilderness Society, 421 U.S. 240, 247, 95 S.Ct. 1612, 1616, 44 L.Ed.2d 141 (1975). The statutory authority for awarding attorney’s fees in § 1983 cases is set forth in 42 U.S.C. § 1988(b). That section provides, “[i]n any action or proceeding to enforce a provision of sections 1981 ... [or] 1983 ... of this title ... the court, in its discretion, may allow the prevailing party ... a reasonable attorney’s fee as part of the costs.” 42 U.S.C. § 1988(b) (1988 & Supp. V 1993). The standard to be used in determining whether a request for attorney’s fees by a prevailing defendant should be approved is set forth in Christiansburg Garment Co. v. EEOC, 434 U.S. 412, 98 S.Ct. 694, 54 L.Ed.2d 648 (1978). In that case, the Supreme Court held that “a district court may in its discretion award attorney’s fees to a prevailing defendant in a Title VII ease upon a finding that the plaintiffs action was frivolous, unreasonable, or without foundation, even though not brought in subjective bad faith.” Id. at 421, 98 S.Ct. *61at 700. Although Christiansburg Garment dealt with Title VII fee awards, the Supreme Court has subsequently indicated that “[t]he legislative history of § 1988 indicates that Congress intended that ‘the standards for awarding fees be generally the same as under the fee provisions [contained in Title VII] of the 1964 Civil Rights Act.”’ Hensley v. Eckerhart, 461 U.S. 424, 433 n. 7, 103 S.Ct. 1933, 1939 n. 7, 76 L.Ed.2d 40 (1983). Thus, the analysis adopted by Christiansburg Garment in determining whether to award.attorney’s fees to a prevailing party is equally applicable to the matter before us.
In Christiansburg Garment, the prevailing party was a defendant, whereas in the case at bar the prevailing parties are intervening defendants. The question whether an intervening defendant may also be considered a prevailing party entitled to an award of attorney’s fees is not free from doubt. We are prepared to assume, arguendo, that the answer is in the affirmative. See Donnell v. United States, 682 F.2d 240, 245-49 (D.C.Cir.1982), cert. denied, 459 U.S. 1204, 103 S.Ct. 1190, 75 L.Ed.2d 436 (1983). However, for the reasons given in Donnell, we would think that such an award would be justified only where the intervening defendant had clearly made a substantial contribution to the successful result. And, in any event, the district court’s discretionary award of attorney’s fees would be justified only in those situations where, under the Christiansburg Garment standard, the plaintiffs “claim was frivolous, unreasonable, or groundless, or [when] the plaintiff continued to litigate after it clearly became so.” 434 U.S. at 422, 98 S.Ct. at 701.
Plaintiff argues that the award of attorney’s fees by the district court in favor of the intervenors and against the plaintiff is. erroneous as a matter of law because it is contrary to controlling Supreme Court precedent. In the case at bar, the district court did not arrive at its decision to award attorney’s fees by applying the standard as set forth in Christiansburg Garment above. Rather, the district court stated:
To award attorney fees to a prevailing intervenor against a civil rights plaintiff ... would appear to penalize a plaintiff without a finding that his or her claim was frivolous, unreasonable or groundless. We found, however, that doing so in this case would further the underlying purpose behind awarding attorney fees in civil rights actions....
Flaherty, slip op. at 4 (August 23, 1993) (citing Flaherty, slip op. at 13, 17 (Sept. 9, 1991)). The district court acknowledged that it never made findings that the plaintiffs claim was frivolous, unreasonable or groundless. Instead, the district court reasoned that it would be proper to realign the parties and treat the Commonwealth as a defendant for fee award purposes because it would further the congressional goal of attacking discrimination by encouraging civil rights lawsuits. Flaherty, slip op. at 17 (Sept. 9, 1991).
The district court decided to treat both the City as well as the Commonwealth as civil rights defendants because both entities assumed identical postures when they allowed the injunction to exist indefinitely and left in place discriminatory hiring practices pursuant to what intervening defendants characterized as an unconstitutional quota system. Flaherty, slip op. at 15 (Sept. 9, 1991). Additionally, the district court concluded that the plaintiff Commonwealth assumed characteristics of a defendant by opposing the intervention of other parties. Id. We see no reason for the Commonwealth to be realigned as a defendant. The status of the Commonwealth as a plaintiff seeking a civil rights remedy was not diminished or changed simply by reason of its not seeking to obtain a permanent injunction after a preliminary injunction had been granted, nor by its objecting to the intervention of other parties.
While it is true that awarding attorney’s fees to prevailing intervening defendants will undoubtedly encourage some civil rights lawsuits, we believe that the analysis undertaken by the district court fads to adequately account for the detriment caused by awarding attorney’s fees against plaintiffs whose claims are not frivolous, unreasonable, or groundless. To accept the reasoning of the district court would require us to expand the rule of Christiansburg Garment to allow the award of attorney’s fees to defendants in cases even where a plaintiffs claim is meritorious. Intervening defendants advocate a rule that would award attorney’s fees against a plaintiff who, in the context of a preliminary or permanent injunction, succeeds on the mer*62its, but then fails to notify the court when the injunction may no longer be valid as a result of a change in the law. We cannot accept such an award structure.
Intervening defendants’ sole argument is that absent an award of attorney’s fees, civil rights suits will be chilled because similarly situated potential intervenors will not initiate court proceedings. We do not believe there is force in such an argument. Potential in-tervenors will continue to initiate court proceedings because the intervenor will always be in a position to seek attorney’s fees from the defendant who is unsuccessful. Additionally, under the intervening defendants’ scheme, any gains which may be achieved by awarding fees to intervening defendants might be eroded by the chilling effect that such a rule of law would have on potential plaintiffs. The uncertainty created by such a rule might discourage some plaintiffs from filing suit for fear that even if they initially prevail in the lawsuit, they may ultimately be liable for attorney’s fees. The most efficient way to balance the competing concerns of encouraging potential intervenors to intervene and simultaneously not discouraging plaintiffs from filing suit in the first instance is to continue to take advantage of the fee award structure that already exists, namely to award fees to the prevailing party and against the losing defendant.
In this case, the City of Pittsburgh failed to challenge a legally questionable preliminary injunction, and allowed it to remain in effect for over fifteen years. If the district court in the first instance had ordered the City of Pittsburgh to pay 100% of the attorney’s fees, then the dual purposes of encouraging civil rights litigation by intervenors yet not chilling a plaintiff from filing suit would have been served. As the district court noted, “[requiring the original plaintiff in a civil rights action to pay a portion of the Intervenors’ attorney fees is, perhaps, unprecedented.” Flaherty, slip op. at 7 (August 23, 1993). We decline to expand the rule of Christiansburg Garment and create such precedent. A prevailing party may still only recover against a plaintiff in a civil rights suit where plaintiffs suit is frivolous, unreasonable, or groundless.
B. Award of Attorney’s Fees as an Alternative to Dismissal Under Federal Rule Of Civil Procedure 41(b)
The district court also held that an award of attorney’s fees was justified as an alternative sanction to dismissing the case for failure to prosecute. Accordingly, although we find that the award of attorney’s fees was not proper under 42 U.S.C. § 1988, we must also consider whether an award is appropriate as an alternative to dismissal under Federal Rule of Civil Procedure 41(b). Our review of the district court’s fee award, where no facts are in dispute, is plenary. Quiroga, 934 F.2d at 502.
The Commonwealth argues that nothing in the language of Rule 41(b) provides for an award of attorney’s fees as an appropriate alternative to dismissing a ease. Although a district court may impose attorney’s fees as a sanction under its inherent power, see Roadway Express, Inc. v. Piper, 447 U.S. 752, 765-66, 100 S.Ct. 2455, 2463-64, 65 L.Ed.2d 488 (1980), there must be some factual predicate which would indicate that the plaintiff was less than diligent in either prosecuting its case or complying with a court order. See Poulis v. State Farm Fire and Cas. Co., 747 F.2d 863, 869 (3d Cir.1984) (award of attorney’s fees would be proper in light of dilatoriness of plaintiffs counsel). We must thus decide whether the district court erred in finding this sanction appropriate.
In support of its alternative justification for awarding attorney’s fees, the district court noted the following concerns: (1) the Commonwealth’s failure to prosecute the action and seek a final adjudication on the merits in light of new Supreme Court precedent, thus allowing what had become a legally questionable preliminary injunction to remain the status quo for over fifteen years; and (2) the Commonwealth’s failure to urge the district court to review the City’s efforts at eliminating discriminatory hiring practices. Flaherty, slip op. at 14-15 (September 9, 1991). Thus, from the record before us, it appears that the district court pointed to the exact same conduct of the Commonwealth when awarding attorney’s fees under Rule 41(b) as it did when awarding attorney’s fees under 42 U.S.C. § 1988.
We cannot conclude that the Commonwealth’s conduct was dilatory or an exercise of bad faith. First, we do not think it a prudent rule to require a plaintiff who pre*63vails on a preliminary injunction matter to run to the courthouse every time he or she suspects that the legal support for the injunction may have been undermined by recent caselaw. Second, the City, rather than the Commonwealth, would have been the appropriate entity to petition the district court to review the police department’s attempts to eliminate its discriminatory hiring practices. Because the Commonwealth was not legally accountable for allowing the preliminary injunction to remain in place in excess of fifteen years, there is no justification based on the undisputed facts in the record for awarding attorney’s fees as an alternative to dismissal. The district court erred as a matter of law in awarding attorney’s fees as an alternative to dismissal under Rule 41(b).
III. Conclusion
We will reverse the district court’s award of attorney’s fees in favor of the intervening defendants and against the plaintiff Commonwealth of Pennsylvania. The district court erred in awarding attorney’s fees against a plaintiff in a civil rights suit without finding that the plaintiffs suit was frivolous, unreasonable, or without foundation. The district court also erred by realigning the plaintiff Commonwealth as a civil rights defendant for the purpose of awarding attorney’s fees. In addition, the facts of this ease do not warrant an award of attorney’s fees against the plaintiff as an alternative to a Rule 41(b) dismissal.
