JOHNSON, Circuit Judge:
The plaintiffs, Mexican-American citizens of Lamb County, Texas, claim that they are entitled to attorneys’ fees under the Voting Rights Act of 1965, 42 U.S.C. § 19737(e), and the Civil Rights Attorneys’ Fees Awards Act of 1976, 42 U.S.C. § 1988, for the role they played in defendant County’s adoption and implementation of a legally sound voting district apportionment plan. They also seek a permanent injunction against future malapportionment of the County’s county commissioner and justice of the peace precincts. The district court denied both requests. It held the injunction unnecessary, in view of the County’s present compliance with federal apportionment requirements and the lack of an immediate threat to modify or abandon the plan presently in force. Neither would it award fees. The court decided that, far from being the catalyst of change, the plaintiff’s lawsuit had no significant effect. It found, to the contrary, that the defendants were on the verge of adopting the legally sufficient plan and submitting it for preclearance when the plaintiffs filed their lawsuit. The plaintiffs appealed both aspects of the ruling. We find no warrant in the record to overturn the district court’s decision. Its judgment is accordingly affirmed.
I.
Lamb County, Texas became subject to the election procedure preclearance provisions of the Voting Rights Act of 1965, 42 U.S.C. § 1973 et seq., on November 1, 1972. From that date forward the County’s apportionment plans stood in clear, conceded violation of both the Voting Rights Act and the Constitution’s one-man/one-vote principle. A reapportionment plan in effect from January 1, 1973 until early 1982 was implemented without the requisite preclearance by the Attorney General, Section 5, Voting Rights Act of 1965, 42 U.S.C. § 1973c; that plan created population deviations among the districts in excess of 100%. In 1976 the 1973 plan, along with several post-1973 modifications, was submitted to the Justice Department. The Attorney General denied preclearance and warned the County that elections could not be held under the plan [1069]*1069until it was approved. Undeterred, the County continued to use the plan in its biennial elections.
Pressure to conform the County’s voting procedures to the constitution and federal law began to mount in late 1978. A request for redistricting by a local Chamber of Commerce prompted the County Commissioner’s Court to establish a citizen’s committee on reapportionment. The matter languished in committee until the 1980 census got underway; the committee then decided to postpone action until up-to-date census data became available. In the spring of 1981 redistricting efforts began in earnest. The committee and a city employee, all laymen to the intricacies of voting district apportionment, devised and submitted a series of plans to the County Commissioners. The last of the plans was adopted and submitted for preclearance in September 1981.
Shortly after submission of the 1981 plan the plaintiffs, Victoria Posada, Melquiarez Sanchez, Jesusa Bosquez, and Ignacio Rendon, first appeared on the scene via a request for a copy of the 1981 plan made by their attorney to the County Judge. In late September the plaintiffs submitted an extensive objection to the 1981 plan to the Justice Department. The plaintiffs did not send a copy of their objection to the County, or notify it that they had filed an objection with the Attorney General. In November 1981 the Justice Department notified the County that the data it had submitted in support of the plan was seriously inadequate, and requested further information.
The County surmised from the Justice Department’s letter that its 1981 plan was too flawed to withstand the government’s scrutiny. Finally acknowledging its need for skilled help, the County retained an attorney and a college professor, both experienced in redistricting, to assist it in devising a proper plan. Soon thereafter, the County notified the Justice Department that it intended to redraw the lines. Additional census data was obtained; in December, a completely revised plan began to take shape. Late in the month, the experts advised the County Judge that they expected the changes to be drastic.
On January 6, 1982, the plaintiffs’ attorney informed the county’s attorney and the County Judge that the plaintiffs intended to file suit. The County apprised the plaintiffs that it was in the final stages of preparation of a completely new plan, that it intended to submit the plan for preclearance no later than February 15, and that it would use the plan in the upcoming primary elections. Notwithstanding, the plaintiffs filed their complaint on January 13. A hearing on the plaintiffs’ request for injunctive relief was set for January 21.
The county commissioners tentatively approved the plan and set it for the requisite public hearings before the district court hearing convened.1 At the district court hearing on January 21, the County represented that its new plan was virtually complete and would be submitted to the Justice Department no later than February 5. It advised the court that it had no intention of holding any future elections under the concededly unconstitutional 1973 plan, and stated that it intended to enter an order extending the spring primary election schedule as necessary to insure that the new plan could be precleared and properly implemented. Based on those representations, the district court denied the plaintiff the immediate injunctive relief they sought against the use of the 1973 or 1981 plans. Instead, it recessed proceedings until February 3 to allow the County time to follow through on its plans.
The County conducted the public hearings as scheduled the following week. The local citizenry strongly opposed the plan. Most of the criticism focused on the plan’s proposal to divide the communities of Littlefield and Olton into minority and nonminority segments and join the minority sections into a single, noncontiguous minority [1070]*1070precinct. The commissioners responded to their constituents’ adverse reactions by reminding them that a lawsuit was pending, and noting that another census would bring a new opportunity to redraw the lines.
The plan was adopted by the County following the final public hearings on January 26, and promptly submitted for preclearance. The resumption of district court proceedings, scheduled for February 3, was cancelled on the parties’ agreement that the plan and the submission satisfied the plaintiffs’ complaints.2 On February 16, at the County’s request, the district court and the County entered simultaneous, identical orders extending the election deadlines for the spring primary. The plan was approved by the Justice Department on April 5,1982. May elections were conducted under the new plan. Several weeks after the elections the plaintiffs sought and were denied a permanent injunction and attorneys fees.
II.
Permanent injunctions are never lightly given. They are hedged about with circumspection: to win one, a petitioner must show a clear threat of continuing illegality portending immediate harmful consequences irreparable in any other manner. United States v. W.T. Grant Co., 345 U.S. 629, 73 S.Ct. 894, 898, 97 L.Ed. 1303 (1953); Baldwin Metals Co., Inc. v. Donovan, 642 F.2d 768, 775 and n. 17 (5th Cir.1981). The cautionary rhetoric of black-letter law binds with ferocity when the federal courts are asked to intervene in the legislative processes of a state, or its political subdivisions. More is called up than our usual reluctance to divert the course of private behavior; such a request, if granted, supplants the non-representative branch for the consensus of representatives, and interjects deeply, directly and finally the strictures of the federal government into the domain of the state. But cognizance of comity does not command abstinence. Encroachments on the exercise of the civil liberties secured by the Constitution are barred no less when threatened by majoritarian domination of the political organs of the state.
Our deepest concerns are awakened by legislative repression of minorities’ political participation. Trammelling of elective rights by the state’s representative bodies distorts the processes of consensus by muffling — or muting altogether — the voices of the less favored. It is a body blow to the body politic. Where it appears, it warrants close scrutiny; when it exists, it requires a firm judicial response.
The County’s record under the Voting Rights Act is a deplorable history of flagrant, persistent violations of minority voting rights and defiance of federal election law. The plaintiffs urge that the County’s pattern of malapportionment, coupled with its officials’ responses to their constituents’ opposition to the new plan, foreshadows a return to discriminatory practices, and request an order demanding continuing compliance. But we are less sure than the plaintiffs that judicial action is now necessary. Extrajudicial constraints — always preferable to our intervention — have pressed the County into present compliance. Aside from those few remarks the district court found were meant to allay a disgruntled citizenry, we have found no intimations that the County contemplates rescinding its plan in favor of one resembling the old. We agree with that court that, absent more concrete evidence that the County is about to return to its old ways, federal judicial intervention is presently unwarranted. Lubbock Civil Liberties Union v. Lubbock Independent School District, 669 F.2d 1038, 1049 (5th Cir.1982), cert. denied, - U.S. -, 103 S.Ct. 800, 74 L.Ed.2d 1003 (1983); Meltzer v. Board of Public Instruction of Orange County, Florida, 548 F.2d 559 (5th Cir.1977), affirmed on rehearing, 577 F.2d 311, 1978, cert. denied, 439 U.S. 1089, 99 S.Ct. 872, 59 L.Ed.2d 56 (1979)3
[1071]*1071Our refusal to act should not be understood to condone the County’s practices. Equal access to the franchise is the pulse of democratic government. Should evidence of the County’s suppression of minority voting rights emerge, the federal courts will not hesitate to take the steps necessary to secure the right of full and fair participation in just elections.
III.
The plaintiffs stake their claim to attorney fees on two assertions of victory. First, they claim that their opposition to preclearance of the 1981 plan contributed substantially to the Justice Department’s decision to request more information, and so indirectly spurred the County to abandon that plan in favor of fresh efforts. Second, they claim that their lawsuit forced the County to make good on its declared intentions to have a constitutionally adequate plan precleared and in place in time for the spring primarys. The district court disagreed. On its evaluation of events, the plaintiff simply caught the train as it pulled out of the station. It found that from November 1981 on “all defendants were diligently working to have a plan submitted and in effect in time to be used in the 1982 elections,” and that “[t]he plan was virtually complete when, on January 1[3], 1982 the instant suit was filed by the plaintiffs,” Mem.Op. at 2. It concluded that a constitutional plan “would have been accomplished in time for the 1982 elections regardless of the plaintiffs’ complaint in this case,” id. at 5.
Attorneys fees are available under § 1973 I (e) of the Voting Rights Act4 and § 19885 to “prevailing parties” in voting rights litigation. The phrase carries the same general meaning under both acts, S.Rep. No. 295, 94th Cong., 1st Sess. 40 (1974), reprinted in [1975] U.S.Code Cong. & Admin.News 774, 807; Hensley v. Eckerhart,-U.S.-, 103 S.Ct. 1933, 1939 n. 7, 76 L.Ed.2d 40 (1983); Commissioners of Medina County, Texas v. United States, 683 F.2d 435, 440 n. 6 (D.C.Cir.1982); Bly v. McLeod, 605 F.2d 134, 138-39 (4th Cir.1979); Caserta v. Kelly, 507 F.Supp. 561, 563 (S.D.Tex.1981) (three-, judge court.). A “prevailing party” is one whose “ends are accomplished as the result of the litigation even without formal judicial recognition,”6 Williams v. Leatherbury, 672 F.2d 549, 550 (5th Cir.1982); Iranian Students Association v. Edwards, 604 F.2d 352, 353 (5th Cir.1979); Criterion Club of Albany v. Board of Commissioners, 594 F.2d 118, 120 (5th Cir.1979); see Maher v. Gagne, 448 U.S. 122, 100 S.Ct. 2570, 2575, 65 L.Ed.2d 653 (1980), and who “can show both a causal connection between the filing of the suit and a defendants’ action and that the defendants’ conduct was required by law,” Williams 672 F.2d at 551; Nadeau, 581 F.2d at 281; see Long v. Bonnes, 455 [1072]*1072U.S. 961, 102 S.Ct. 1476, 71 L.Ed.2d 681 (1982) (Rehnquist, J., dissenting from denial of certiorari); Johnston v. Jago, 691 F.2d 283, 286 (6th Cir.1982). Two of the three elements are not in dispute. The plaintiffs’ ends were plainly accomplished: they sought to put a stop to the County’s longstanding violation of the one-man/one-vote principle, to end the County’s dilution of minority voting strength, and to achieve compliance with the Voting Rights Acts preclearance provisions. The plan used in the 1982 primary satisfied them, and passed the Attorney General’s preclearance review. Neither is there a dispute over whether the County’s conduct was required by law. The defendant concedes that its development, submission to preclearance and implementation of a non-discriminatory plan was demanded by the Constitution and federal statutes. Disagreement focuses solely on the requisite causal connection.
Causal connection is established by evidence that the plaintiffs’ lawsuit was a “substantial factor or a significant catalyst in motivating the defendants to end their unconstitutional behavior,” Williams, 672 F.2d at 551; Coen v. Harrison County School Board, 638 F.2d 24, 26 (5th Cir.1981), cert. denied, 455 U.S. 938, 102 S.Ct. 1427, 71 L.Ed.2d 647 (1982); Robinson v. Kimbrough, 620 F.2d 468, 476 (5th Cir.1980). The plaintiffs do not have to prove that their efforts were the sole reason for the defendant’s rectifying actions. Some award is due so long as the plaintiffs’ actions made an important contribution to the improvements achieved. Hensley, 103 S.Ct. at 1939, 1942 n. 14; Disabled in Action v. Mayor & City Council of Baltimore, 685 F.2d 881, 885-86 (4th Cir.1982); United Handicapped Federation v. Andre, 622 F.2d 342, 348 (8th Cir. 1980). But participation without contribution is not enough. A fee award is not justified if the plaintiffs’ suit was “completely superfluous,” Nadeau, 581 F.2d at 281, to the attainment of relief. Williams, 672 F.2d at 551; Criterion Club of Albany, 594 F.2d at 120; compare Ramos v. Koebig, 638 F.2d 838, 845 (5th Cir.1981). “A civil rights plaintiff may not collect attorney’s fees for demanding that a state officer do what he would have done in any case,” Coen, 638 F.2d at 26.
At bottom, the inquiry is an intensely factual, pragmatic one. Williams, 672 F.2d at 551; Coen, 638 F.2d at 26-27 n. 1; Criterion Club of Albany, 594 F.2d at 120. Clues to the provocative effects of the plaintiffs’ legal efforts are often best gleaned from the chronology of events: defendants, on the whole, are usually rather reluctant to concede that the litigation prompted them to mend their ways. Ramos, 638 F.2d at 845; Robinson, 620 F.2d at 476; Nadeau, 581 F.2d at 281. But credibility choices in the resolution of conflicting testimony are the district court’s province as fact finder. Those conclusions can be set aside only if the evidence leaves us with the definite and firm conviction that the district court has made a mistake. Pullman-Standard v. Swint, 456 U.S. 273, 102 S.Ct. 1781, 1788, 72 L.Ed.2d 66 (1982) citing United States v. United States Gypsum Co., 333 U.S. 364, 68 S.Ct. 525, 541, 92 L.Ed. 746 (1948).7
The pivotal issue is, then, whether the district court clearly erred in holding that the plaintiffs’ lawsuit was not a significant catalyst in the defendant’s adoption of the [1073]*10731982 plan. But the plaintiffs initial argument in support of their claim that they prevailed presents the usual problems of factual resolution in an unusual context. The plaintiffs maintain that they are entitled to attorneys fees for the results they claimed to have achieved through prelitigation participation in the Attorney General’s preclearanee review8 of the 1981 plan. In support of their claim, they contend that the preclearance review is a “proceeding" within the meaning of the fee awards statutes’ authorization of fees for success obtained “in any action or proceeding to enforce” the Constitution’s voting guarantees, see ante nn. 2 & 3; cf. New York Gaslight Club, Inc. v. Carey, 447 U.S. 54, 100 S.Ct. 2024, 64 L.Ed.2d 723 (1980) (holding that the phrase “any action or proceeding” as used in section 706(k) of Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e-5(k) (1976), authorizes awards of attorney’s fees for work done by the prevailing complainant in state administrative and judicial proceedings to which the complainant was referred pursuant to the provisions of Title VII).
It is by no means clear to us that Congress intended the word “proceeding” as used in section 19737 (e) to encompass the preclearance process. Textual interpretation of the Voting Rights Act lends no support to the argument: “proceeding” is used throughout the statute interchangeably with “action” to refer to judicial proceedings, see, e.g., § 1973c (referring to actions for declaratory judgments as “proceedings”); § 1973j(f) (referring to certain actions by the Attorney General for preventive relief and to criminal actions under the Act as “proceedings”); § 19737 (referring to actions for declaratory judgments as “proceedings”). The Act does not use the word in creating or defining the Attorney General’s obligation to conduct preclearance reviews, 42 U.S.C. § 1973c;9 compare New York Gaslight, 100 S.Ct. at 2029-30. Neither does the statutory design of the Act’s enforcement mechanisms support a conclusion that the Congress intended preclearance proceedings to be an integrated part of private enforcement mechanisms, compare New York Gaslight, 100 S.Ct. at 2031-32. Indeed, precisely the opposite appears. By statutory design, preclearance proceedings are independent of private remedies for the enforcement of the Voting Rights Act. “Once a plan has been submitted to [1074]*1074the Attorney General, although interested parties may voice their opposition to or support of the plan, the final decision is the Attorney General’s alone,” Commissioner’s Court of Medina County, Texas, 683 F.2d at 440. The Attorney General’s decision to grant or deny preclearance is not subject to judicial review, City of Dallas v. United States, 482 F.Supp. 183, 185 (D.D.C.1979) (three-judge court). But by the same token, plans precleared remain vulnerable to attack in the courts on the same grounds subject to the Attorney General’s review, 42 U.S.C. § 1973c.10 The Attorney General’s approval has no preclusive effect on interested parties, City of Dallas, 482 F.Supp. at 185. But most important is that, through creation of the preclearance review, the Congress entrusted the Attorney General with an affirmative obligation to secure enforcement of the provisions of the Voting Rights Act. By law, the Attorney General bears the responsibility for vindicating the public interest under the Act by achieving full and uniform compliance with its provisions throughout the jurisdictions of its application, see Apache County v. United States, 256 F.Supp. 903, 908 (D.D.C.1966) (three-judge court); see also NAACP v. New York, 413 U.S. 345, 93 S.Ct. 2591, 2604, 37 L.Ed.2d 648 (1973). The provisions for attorney’s fee awards under section 19731 (e) and section 1988 were intended to enable private citizens to serve as “private attorneys general” in bringing suits to vindicate the civil rights laws, see 122 Cong.Rec. 35127 (1 Oct. 1976) (remarks of Rep. Holtzman in the House debates on the Civil Rights Attorneys Fees Awards Act of 1976).11 That interest is far less compelling when the private action occurs in the very context of the Attorney General’s action on behalf of those whose rights are affected.
In view of the latter consideration, we find it unnecessary to decide in this case whether attorney’s fees can ever be awarded for participation in a preclearance review, either prior to or in the course of litigation.12 Assuming for the sake of argument that fees are available in such circumstances, we believe that their award is governed by standards analogous to those applicable to fee applications for work done as a private intervenor on the side of the government in its judicial actions to enforce the civil rights laws. Confronted with a request for fees by intervenors on the side of the United States in a section 5 declaratory judgment action under the Voting Rights Act,13 the District of Columbia Cir[1075]*1075cuit held that the Attorney General’s participation in satisfaction of his affirmative, statutorily-imposed obligation to enforce the voting rights laws constituted a “special circumstance,” Newman v. Piggie Park Enterprises, Inc., 390 U.S. 400, 88 S.Ct. 964, 966, 19 L.Ed.2d 1263 (1968) creating an exception to the usual presumption in favor of granting attorney’s fees to a party whose objectives have been achieved. Donnell v. United States, 682 F.2d 240, 247 (D.C.Circuit 1982). Drawing on precedent denying fees to intervenors whose efforts made little or no independent contribution to the result achieved,14 the Court held that fees may be awarded only if the governmental litigant did not adequately represent the intervenors’ interest, if the intervenors proposed different theories and arguments for the court’s consideration, and if the work the intervenor performed was of important value to the court, Donnell, at 248-49; accord, Alabama Power Company v. Gorsuch, 672 F.2d 1, 4 (D.C.Cir.1982); Silberman v. Bogle, 683 F.2d 62, 65 (3rd Cir.1982).
The similarities between section 5 declaratory judgment proceedings and preclearance reviews, see ante n. 11, convince us that Donnell’s approach applies equally here. We therefore hold that if fees can be obtained at all for private opposition mounted in a preclearance review, which review resulted in the Attorney General’s expression of dissatisfaction with the plan, the award must be justified by a showing that the private objectors’ participation, through particularly astute criticism or creative legal argument, changed the result that the Attorney General would otherwise have reached. We will not presume that the Attorney General has failed adequately to satisfy his statutory obligations to enforce the public interest in compliance with the voting rights legislation, or that the reservations the Attorney General voiced would have passed unnoticed absent objections filed by private parties, Donnell, 682 F.2d at 248; Silberman, 683 F.2d at 65. Absent evidence that the objectors’ work had a substantial independent effect on the outcome of the preclearance review, the threshold burden to justification for an award of fees for preclearance participation has not been met.
The plaintiffs’ claim to victory does not pass muster. Observing that some of the deficiencies in the 1981 plan noted by the Attorney General in his November letter to the County were the same as problems they had pointed out in the objection they submitted in opposition to the County’s application for preclearance, the plaintiffs claim partial responsibility for the Attorney General’s expression of dissatisfaction, and partial credit for the County’s consequent decision to abandon the 1981 plan. It is quite possible that their extensive comment assisted the Attorney General in organizing the pertinent materials, identifying the problem areas and crystalizing the issues. But there is no evidence that their submission carried the Attorney General beyond the analysis he would have otherwise have undertaken. Without such a showing, we cannot credit the plaintiffs with responsibility for the result of the Attorney General’s review, or with consequent, indirect influence on the County’s decision to abandon the 1981 plan. The Attorney General’s response must be considered the result of his satisfaction of his affirmative statutory obligations. The County’s decision must be attributed to its justifiable concern over the Justice Department’s dissatisfaction.
We are left, then, with the plaintiffs’ claim that had they not filed suit, the Coun[1076]*1076ty would not have adopted the 1982 plan either at all, or at least in time for the spring elections.15 The question is close. As the plaintiffs point out, the record of the public hearings discloses vigorous public opposition to the plan, the County officials’ responses disclosed their personal dissatisfaction with it, and the County’s history did not augur well for voluntary compliance. The district court recognized these factors, but found decisive the commitment to compliance exhibited by the County’s dedicated efforts, partially completed before litigation began, to adopt a plan meeting constitutional and federal statutory standards, its avowed determination to achieve preclearance and implementation in time for the upcoming elections, and its unhesitating cooperation with all efforts to effect a sound plan.
The chronology of events is of little assistance. The plaintiffs filed suit just at the critical juncture of the experts’ unofficial, though solicited, proposal of an adequate plan and the plan’s official endorsement and implementation. Certainly, the County would have, and did, take seriously the possible sanction of judicial action if it failed to act. But the district court found that this sanction was imposed after the County had already responded to Justice Department pressure and resolved to comply with the law. In its view, the plaintiff’s lawsuit may well have strengthened this resolve by making more immediate the consequences of dereliction of duty — but in doing so, the district court found, the plaintiff’s action only sharpened the pressures to hew to a course of action already begun.
We have no crystal ball. We cannot say with certainty that the County would have defaulted yet again had the plaintiffs not intervened. That being so, we cannot set the district court’s decision aside as clearly erroneous.
The judgment of the district court is accordingly affirmed.
AFFIRMED.
