OPINION OF THE COURT
GARTH, Circuit Judge:
This case presents to us, in an unusual procedural context, the difficult question of determining which of two allegedly conflicting contracts is to dictate the plaintiff employer’s course of conduct. We must resolve whether in reducing a company’s work force an employer is obligated to adhere to collective bargaining agreement provisions requiring layoffs in reverse order of seniority, or whether the employer is obligated to implement the provisions of a conciliation agreement made with the Equal Employment Opportunity Commission (EEOC) to retain among its employees a larger proportion of minority group and female workers. It is agreed among the parties that layoffs in reverse order of seniority will have a disproportionate effect upon minority group and female workers, as they are the most recently hired employees. Despite this consequence, we reverse the judgment of the district court and hold that the provisions of the collective bargaining agreement must govern in this procedural context.
I.A. Procedural History
On July 18, 1974, Jersey Central Power & Light Company (“Company”), the employer, brought the instant action pursuant to 28 U.S.C. §§ 2201, 22021 in the District Court for the District of New Jersey. The Company sought a judgment declaring its rights and obligations under: (1) a collective bargaining agreement between the Company and the Unions,2 and (2) a conciliation agreement among the EEOC, the Company and the Unions.3 Named as defendants in the action for declaratory judgment were the Unions, the EEOC, the United States Office of Federal Contract Compliance (OFCC), the United States General Services Administration (GSA), and the New Jersey Division of Civil Rights.4 The Company presented itself in this litigation as a “neutral” party, taking no position as to which of the two contracts must govern the manner by which a substantial cutback in employment would be effectuated.5 In this posture, the Company sought guidance from the district court, asserting that economic circumstances required it to lay off substantial numbers of employees. The Company alleged that it could not determine the specific individuals to be affected until the court declared which of the two agreements was to govern the layoff procedure.
[692]*692Contending that it faced multiple suits for back pay, irreparable injury to itself and to the public, and severe financial inroads on its resources, on August 23, 1974, the Company moved for an order requiring the defendants to shove cause why summary judgment should not be granted “declaring the respective rights of the parties and whether plaintiff [the Company] violated its collective bargaining agreement with [the Union] defendants . . . and the Conciliation Agreement entered into on December 3, 1973 by the layoff ... of [designated] employees. . . . ” 6
On September 5, 1974, the return date of the order to show cause, defendants GSA and OFCC moved to dismiss the complaint pursuant to Fed.R.Civ.P. 12 for failure of the complaint to state a claim upon which relief could be granted and for lack of subject matter jurisdiction in the federal district court. Defendant EEOC, in turn, did not contest the district court’s jurisdiction but instead opposed the Company’s motion on the grounds that summary judgment could not be granted because material facts were in dispute.7 After the sub[693]*693mission of briefs and affidavits, the district court held a hearing on motions of the Company and GSA and OFCC, at the conclusion of which the court rendered an oral opinion.8 The district court denied the motion to dismiss brought by GSA and OFCC9 and granted partial summary judgment, requiring the Company to lay off employees in a manner inconsistent with the collective bargaining agreement to avoid a reduction in the percentage of females and minority group members in the work force. As such, the district court rejected the Unions’ contentions that the collective bargaining provisions (layoff by reverse order of seniority) were to control without modification.
In particular, the district court’s order required that: (1) the seniority provisions of the collective bargaining agreement could not be construed in such a manner as to frustrate the purpose of the conciliation agreement (to wit: that at the end of five years females and minority group members would constitute a proportion of the Company’s work force which would approximate the proportion of those groups in the relevant labor market);10 (2) the provisions of, the conciliation agreement were to prevail over the provisions of the collective bargaining agreement to the extent that the two agreements were in conflict; and (3) layoffs were to be accomplished in such a manner so that upon completion, the minority group and female worker ratios would be the same as those existing as of July 27, 1974, (approximately one month prior to the commencement of layoffs).
The district court granted leave to file an interlocutory appeal pursuant to 28 U.S.C. § 1292(b). Pursuant thereto the defendant Unions applied for leave to appeal and a panel of this Court granted such leave
I.B. Facts13
The Company is a large public utility operating in New Jersey and engaged in the generation and distribution of electrical power throughout approximately half of that State. As of June 29, 1974, the Company employed 3,859 employees, of whom 2,877 were in the bargaining units represented by the Unions involved in the instant proceeding.
On January 28, 1972, a charge had been filed with the EEOC alleging that the Company and the Unions unlawfully discriminated against women and “minority group persons,”14 in violation of Title VII of the Civil Rights Act of 1964. The EEOC investigated the charge and found 15 reasonable cause to believe that the Company discriminated against minority group persons and females with respect to hiring and job assignments.16 Thereafter, a conciliation agreement was entered into among the ' Company, EEOC, and the Unions. The conciliation agreement was signed in January, 1974, to be effective from December 3, 1973 through December 3, 1977. The agreement was divided into several sections. Section I — “General Provisions” — provides, inter alia:
1. It is understood that this Agreement does not constitute an admission by the Respondents of any violation of Title VII of the Civil Rights Act of 1964, as amended.
******
3. The ' Commission agrees not to sue the Respondents over matters contained in this Agreement subject to Respondent’s compliance with the promises and representations contained herein. If the Commission believes that this Agreement has been violated, it shall first attempt to resolve the dispute with the parties; then if no Agreement can be reached, the Commission can seek to enforce this Agreement through the legal process.
4. This waiver by the Commission extends to any matter which is covered by this Agreement. This does not preclude individual Charging Parties, or the Commission itself, from filing charges or suit over new matters or practices which may arise with respect to practices of the Respondents.
5. Respondents agree that all hiring and promotion practices, and any and all other conditions of employment shall be maintained and conducted in a manner which does not discriminate on the basis of race, color, creed, ancestry, religion, sex, national origin, age, place of birth, marital status or liability for services in the armed forces of the United States in violation of Title VII of the Civil Rights Act of 1964, as amended.
******
[695]*695Section III of the conciliation agreement (“Recruitment and Hiring Practices”) Paragraph 9, obligates the Company to make reasonable efforts to “recruit minorities and females into those craft areas where such jobs are to be filled by new hires, where they have,, heretofore been under utilized or not employed.” Paragraph 10 provides that the minority group persons and female recruits for craft jobs are to be given credit for experience gained in the craft with other employers and may be considered for jobs other than those at the entry level. Paragraph 10 concludes that:
The wages, benefits, other conditions of employment and seniority date of such employee shall be determined in accordance with the provisions of the Collective Bargaining Agreement.
Section IV of the conciliation agreement is entitled “Promotion and Transfer” and establishes a special program for female and minority group Company' employees who are to be given preference for promotions and transfers into vacant positions on the basis of their company seniority.17 Paragraph 2 specifically provides: “For purposes of this Conciliation Agreement vacancies occasioned by layoff . . . shall not be considered as vacancies.”
Section V (“Affirmative Action”) establishes a five year affirmative action program designed to increase the percentage of minority group and female employees.18 Among other provisions, the agreement also provides for reporting (Section IX), a modification of the maternity leave policy (Section VI) and certain payments by the Company to employees and others for past discriminatory practices. (Section VII).19
The conciliation agreement has no express seniority provision nor does it expressly modify or alter the seniority provisions found in the collective bargaining agreement.20 Rather, a fair reading of [696]*696the conciliation agreement reveals that it is primarily concerned with the hiring, promotion and transfer of female and minority group employees.
On December 3, 1973, prior to the execution of the conciliation agreement by the Company, the Unions and EEOC, the Company and the Unions entered into a new collective bargaining agreement effective from November 1, 1973 through October 31, 1975. In pertinent part the collective bargaining agreement continues the seniority policies in operation among the bargaining unit employees of the Company.21 In regard to layoffs, the collective bargaining agreement provides inter alia:
3.2. (a) All layoffs, or demotions occasioned because of falling off or curtailment of work, shall be discussed with the Union two (2) weeks in advance of the layoff and shall be made in order of seniority. No senior employee shall be laid off as long as any work which he can reasonably be expected to do is being performed by an employee junior in point of service.
******
3.3. Employees who have been laid off shall be reinstated to employment as need for their services arises, in the reverse order of their layoff.
3.4. Seniority is defined as length of continuous service with the Company . . . .
******
These provisions establish a plant-wide seniority system22 for employees with respect to layoffs.23
The Company in its pleadings asserts that economic considerations compelled it to announce a layoff of employees in July, 1974. The Company estimates that approximately 400 employees will have been laid off by mid-December, 1974. The Unions required strict adherence by the Company to the seniority provisions of the collective bargaining agreement. The EEOC responded to the Company’s layoff plans by indicating that a layoff accomplished by seniority alone would violate the provisions of the conciliation agreement and Title VII of the Civil Rights Act of 1964.24
[697]*697Confronted with two apparently conflicting contracts, the Company instituted this action for declaratory judgment. At about the same time, the Company and the Unions submitted to an expedited arbitration proceeding under their collective bargaining agreement to determine if a layoff of employees in reverse order of seniority would violate the nondiscrimination provision of the collective bargaining agreement.25 On August 21, 1974, the arbitrator held that a layoff in accordance with the seniority provisions of the collective bargaining agreement would not violate the non-discrimination provision of the same document.26
In accordance with the arbitrator’s award, on August 23, 1974, the Company commenced the layoff in reverse order of seniority. Layoffs in this manner continued until September 5, 1974 when the district court issued its opinion which, as previously noted, required accommodation with the conciliation agreement.
After the first week of layoffs, statistics provided by the Company indicated that the layoffs had a disproportionate impact upon minority group employment.27 As of August 30, 1974, one hundred seventy-six (176) employees were identified for layoff or termination, of which 30.7% or 54, were male or female minority group persons. As a result of this first group of bargaining unit employees being laid off, the percentage of male and female minority group employees in the bargaining unit decreased from 7.9% on July 27, 1974 to 6.4% as of August 30, 1974.28 With respect to female employees only, however, the initial layoff had no disparate impact. Both before and after the layoff, women constituted 14.6% of the total workforce and 15.2% of the bargaining unit29
[698]*698Subsequent to the district court’s opinion announced on September 5, 1974, the Company began to program the remainder of its layoffs to comply with the district court’s directive that the female and minority group employee ratios existing as of July 27, 1974 be maintained throughout the layoff process. The Company continued layoffs pursuant to the district court’s directive until October 9, 1974, at which time this Court granted a motion to stay the order of the district court. Since October 9, 1974 the Company has reverted to laying off employees solely by reverse order of seniority.
II. Jurisdiction
We need not make any detailed inquiry into the threshold question of jurisdiction.30 We are satisfied that the pleadings and the record establish the requisite jurisdiction. The complaint, among other jurisdictional allegations,31 [699]*699predicates jurisdiction on § 301(a) of the Labor Management Relations Act of 1947) 29 U.S.C. § 185(a). We agree that in seeking a declaratory judgment as to its collective bargaining agreement with the Unions, the Company has properly invoked our jurisdiction.32 Avco Corp. v. Aero Lodge 735, 390 U.S. 557, 561-562, 88 S.Ct. 1235, 20 L.Ed.2d 126 (1968); see also Serio v. Liss, 300 F.2d 386 (3d Cir. 1961).
We also believe that jurisdiction has been properly invoked with respect to those issues involving the conciliation agreement and the EEOC. In our opinion, inasmuch as the EEOC agreement must be interpreted according to federal substantive law, see United States v. Seckinger, 397 U.S. 203, 209-210, 90 S.Ct. 880, 25 L.Ed.2d 224 (1970), the Company’s cause of action joining EEOC “arises under” laws of the United States within the meaning of 28 U.S.C. § 1331.33 See Illinois v. City of Milwaukee, 406 U.S. 91, 100, 92 S.Ct. 1385, 31 L.Ed.2d 712 (1972); Ivy Broadcasting Co. v. American Tel. & Tel. Co., 391 F.2d 486, 492 (2d Cir. 1968). We are also satisfied that even if there were no independent ground of jurisdiction existing under § 1331,34 that nonetheless there exists jurisdiction ancillary to the proper resolution of the Company’s cause of action based upon the collective bargaining agreement. See Rosado v. Wyman, 397 U.S. 397, 405, 90 S.Ct. 1207, 25 L.Ed.2d 442 (1970); Almenares v. Wyman, 453 F.2d 1075, 1083 (2d Cir. 1971), cert. denied, 405 U.S. 944, 92 S.Ct. 962, 30 L.Ed.2d 815 (1972).
As we have previously indicated, see n. 5 supra, the Company’s action for declaratory judgment presents a justiciable case or controversy, as indeed it must, under Article III of the Constitution. E. g., Lake Carriers Ass’n v. MacMullan, 406 U.S. 498, 92 S.Ct. 1749, 32 L.Ed.2d 257 (1972); Golden v. Zwickler, 394 U.S. 103, 89 S.Ct. 956, 22 L.Ed.2d 113 (1969). A case or controversy in the constitutional sense “must be definite and concrete, touching the legal relations of parties having adverse legal interests.” Aetna Life Insurance Co. v. Haworth, 300 U.S. 227, 240-241, 57 S.Ct. [700]*700461, 464, 81 L.Ed. 617 (1937); see also Maryland Casualty Co. v. Pacific Coal & Oil Co., 312 U.S. 270, 273, 61 S.Ct. 510, 85 L.Ed. 826 (1941). A dispute is not too hypothetical for the proper exercise of federal jurisdiction if there is present an immediate adverse effect on the parties in a concrete situation. See Longshoremen’s Union v. Boyd, 347 U.S. 222, 223-224, 74 S.Ct. 447, 98 L.Ed. 650 (1954). Moreover, in determining whether a dispute has matured to the point at which the judicial function may be properly exercised, a court may look to the announced intentions of the defendants to take adverse action against the plaintiff. Younger v. Harris, 401 U.S. 37, 42, 91 S.Ct. 746, 27 L.Ed.2d 669 (1971).35 In this regard, the defendants here have announced their intention to require Company compliance with each particular contract, although the Company implicitly challenges (albeit inconsistently) each party’s respective interpretations.36 Thus in our view, there exists a justiciable case or controversy. See Super Tire Engineering Co. v. McCorkle, 416 U.S. 115, 94 S.Ct. 1694, 40 L.Ed.2d 1 (1974); cf. National Automatic Laundry & Cleaning Council v. Shultz, 143 U.S.App.D.C. 274, 443 F.2d 689 (1971).
III. Contract Theory
The district court, viewing the instant proceeding as one requiring the interpretation of contracts only, specifically refused to consider the issue of past employment practices of either the Company or the Unions. Although we agree with the district court that the instant controversy must be analyzed according to the principles of general contract law, see United States v. Seckinger, 397 U.S. at 210, 90 S.Ct. 880; Priebe & Sons, Inc. v. United States, 332 U.S. 407, 411, 68 S.Ct. 123, 92 L.Ed. 32 (1947), we must nevertheless differ with that court’s interpretations of the two contracts and, as such, with its issuance of the judgment predicated upon those interpretations.37
In interpreting the two contracts before us, we must: first, determine whether or not an express or implied conflict exists as between the provisions of the conciliation agreement and the provisions of the collective bargaining agreement, and, if such a conflict does exist, which of the two contracts is to govern; second, if no such conflict is held to exist, determine if the collective bargaining agreement must nevertheless be modified to accommodate an overriding public policy. The district court followed a similar approach concluding (1) that to the extent that the conciliation agreement conflicts with the collective bargaining agreement, the conciliation agreement prevails; and (2) that the layoffs are not to be accomplished in the manner prescribed by seniority clauses of the collective bargaining agreement, because such a method of layoffs would “frustrate” the objective of the conciliation agreement. We hold both conclusions of the district court to be erroneous as a matter of law.
[701]*701A. The Two Contracts Do Not Conflict
In our interpretation of both contracts we are governed solely by federal law.38 After comparing and contrasting the provisions of the two contracts, we are of the view that no conflict exists with respect to layoffs.
The conciliation agreement has, as its objective, the percentage increase of females and minority group persons among employees. This objective was to be attained by the Company hiring a greater percentage of minority group and female workers — not by resort to a system of “artificial” seniority. See note 20, supra. As such the conciliation agreement sought an increase in the proportion of female and minority group workers by “hires” and not by “fires.” It is highly significant to us that the conciliation agreement contains no overall layoff procedure or seniority system. Moreover, the express terms of the conciliation agreement do not attempt to affect, nor can we interpret them to affect, the layoff provisions of the collective bargaining agreement.39
The “new hire” method of attaining a higher proportion of female and minority group workers is evident throughout the conciliation agreement. In particular, reference to “new hires” is made in Section III, paragraph 9 of the conciliation agreement, which provides:
Respondent Company shall make a reasonable effort to recruit minorities and females into those craft areas where such jobs are to be filled by new hires, where they have heretofore been underutilized or not employed. To this end, Respondent Company agrees that in each instance where a job is not to be filled from within, pursuant to the Collective Bargaining Agreement and practices thereunder, reasonable efforts will be made to secure a minority or female as outlined in paragraph 1 of the Affirmative Action portion of this Agreement, (emphasis supplied).40
Paragraph 1 of the Affirmative Action program, in turn, is confined solely to “new hire” situations:
Respondent Company is presently undergoing its utilization analysis for preparation of its goals and time tables. The Company agrees to make every reasonable effort to bring its minority and female workforce up to parity by location and EEO — 1 categories as openings for new hires occur and qualified applicants are available within five (5) years, (emphasis supplied).41
[702]*702We regard the conciliation agreement as unambiguous in its requirements that an increased proportion of females and minority group persons be hired, but that once hired, workers in these classes be controlled by the terms and conditions of employment as set forth in the collective bargaining agreement. Accordingly, we read the conciliation agreement as not modifying the promotion, transfer or layoff practices established by the collective bargaining agreement once females and minority group persons have been employed. We base this interpretation, in part, on two provisions of the conciliation agreement. As previously noted, in regard to recruitment and hiring practices, section III, paragraph 10, provides:
The wages, benefits, other conditions of employment and seniority date of such employee shall be determined in accordance with the provisions of the Collective Bargaining Agreement, (emphasis supplied).
Moreover, in the context of promotions and transfer practices, section IV, paragraph 2, in pertinent part provides:
“[Tjhose male minorities/females who are qualified and who had indicated the desire to transfer shall be given the opportunity to transfer, using their total length of Company service, subject to vacancies being available and in a manner consistent with the current Collective Bargaining Agreement. For purposes of this Conciliation Agreement vacancies occasioned by layoff . . . shall not be considered as vacancies, (emphasis supplied).42
We thus interpret the conciliation agreement as being consistent with, rather than in conflict with, the collective bargaining agreement, in that it incorporates the Company seniority system.
EEOC alternatively argues that if not an express, at least an implicit inconsistency exists between the two agreements and that this inconsistency requires a modification of the seniority provisions of the collective bargaining agreement. For EEOC’s argument to succeed, it must persuade us that despite the silence of the conciliation agreement respecting overall seniority, we should nonetheless interpret the two contracts as being inconsistent.
First, EEOC contends that where the subject matter is the same in two contracts but the contracts contain terms inconsistent with each other, the later agreement will supersede the earlier agreement.43 Second, EEOC contends that the Company’s agreement to use “best efforts” to have its work force reflect the racial, ethnic and sex composition in the relevant labor market should be given effect as an implicit modification of the seniority provisions. Third, EEOC argues that the objectives of the [703]*703conciliation agreement (to increase the proportion of female and minority group workers) will be thwarted if effect is given to the seniority provisions of the collective bargaining agreement.
We cannot agree with EEOC’s arguments. First, whether or not a subsequent contract is deemed to supersede an earlier contract is a question of the parties’ intent to ■ be as-, certained from the contracts themselves when they are unambiguous. In order for us to hold that the parties intended the second agreement (here the conciliation agreement) to operate as a substituted contract, the terms of the second contract must be so inconsistent with those of the first that both contracts cannot stand together.44 Here, we can discern no such intent as the conciliation agreement is completely silent on the issue of overall seniority. Hence, despite its later execution we find no inconsistency, apparent or otherwise, between the two contracts. Accordingly, there is no basis to preclude our sustaining both contracts in full.45 See Rosenberg v. D. Kaltman & Co. Inc., 28 N.J.Super. 459, 101 A.2d 94 (1953); compare N. L. R. B. v. Operating Engineers Local 12, 323 F.2d 545, 548 (9th Cir. 1963); Port of Seattle v. United States, 450 F.2d 1363, 1378 (Ct.Cl.1971).
Second, the conciliation' agreement, section III (Recruitment and Hiring Practices) and Y (Affirmative Action Program), requires the Company to use “best efforts” to increase the percentage of female and minority group employees. We do not believe that this undertaking by the Company necessarily modifies by implication a seniority system of layoffs. We interpret the “best efforts” commitment in a context that requires the Company to use its “best efforts” to increase the female and minority group proportion among employees as openings for new hires arise. This is completely consistent with the express terms of the conciliation agreement (see infra). Third, with respect to the objective which EEOC claims is defeated if effect is given to the collective bargaining agreement, we believe EEOC has only partially stated the objective of that agreement. As our analysis reveals, the true objective of the conciliation agreement is to increase the percentage of female and minority group employees through “new hires” only. The express language of the conciliation agreement so provides:
“The Company agrees to make every reasonable effort to bring its minority and female work force up to parity as openings for new hires occur and qualified applicants are available within five (5) years.”
Section V, paragraph 1. We thus do not agree with EEOC or with the district court that layoffs by reverse order of seniority would unlawfully frustrate this objective.46
[704]*704Hence, we conclude that the two agreements are not in conflict either by their express terms or by implication. We are obliged, nonetheless, to proceed to the question of whether an overriding public policy dictates a modification of the collective bargaining agreement.
B. Public Policy
The district court emphasized that the principal purpose of the conciliation agreement between the Company, the Unions and EEOC was to ensure that at the end of five years the proportion of females and minority group employees would approximate the proportion of those groups in the relevant labor market. The primary basis for the district court’s modification of the collective bargaining agreement was the district court’s conclusion that insistence on layoff solely according to the collective bargaining agreement would frustrate47 the purposes of the conciliation agreement.
As our analysis indicates, the district court’s conclusion in this respect is without merit. Consequently, we now believe the appropriate inquiry is whether a seniority clause providing for layoffs by reverse order of seniority must be modified as being contrary to public policy and welfare. Cf. Restatement, Contracts, § 369, at 671 (1932).
In order to declare the provisions of the collective bargaining agreement (entered into by the parties freely and without evidence of fraud) void as against public policy, the contract terms must be invalid on the basis of clear and distinct legal principles. The Supreme Court has stated:
. As the term ‘public policy’ is vague, there must be found definite indications in the law of the sovereignty to justify the invalidation of a contract as contrary to that policy. . . . Only dominant public policy would justify [invalidating contracts] .
Muschany v. United States, 324 U.S. 49, 66, 65 S.Ct. 442, 451, 89 L.Ed. 744 (1945). Pursuant to this principle, public policy of the United States in general, is to be determined from a consideration of the Constitution, treaties, federal statutes and applicable legal precedents. See Hurd v. Hodge, 334 U.S. 24, 34-36, 68 S.Ct. 847, 92 L.Ed. 1187 (1948); Muschany, 324 U.S. at 66, 65 S.Ct. 442; St. Louis Mining & Milling Co. v. Montana Mining Co., 171 U.S. 650, 655, 19 S.Ct. 61, 43 L.Ed. 320 (1898). In the case sub judi'ce we are not without legislative guidance in ascertaining the public policy applicable to the particular situation here presented. Title VII of the Civil Rights Act of 1964 provides Congress’ formulation of public policy. Cf. Twin City Pipe Line Co. v. Harding Glass Co., 283 U.S. 353, 357, 51 S.Ct. 476, 75 L.Ed. 1112 (1931). By Title VII, Congress in the context of employment discrimination supplanted with its own views any [705]*705judicial determination of public policy.48 Cf. United States v. Atlantic Mutual Ins. Co., 343 U.S. 236, 245, 72 S.Ct. 666, 96 L.Ed. 907 (1952) (Frankfurter, J., dissenting).
Our reading of Title VII reveals no statutory proscription of plant-wide seniority systems. To the contrary, Title VII authorizes the use of “bona fide” seniority systems:
Notwithstanding any other provision of this subchapter, it shall not be an unlawful employment practice for an employer to apply different standards of compensation, or different terms, conditions or privileges of employment pursuant to a bona fide seniority. or merit system '.
42 U.S.C. § 200Qe-2(h). More.over, we can discern no “ . . . definite indications ... to justify the invalidation of [such] a contract as contrary to that [public] policy.” Muschany, 324 U.S. at 66, 65 S.Ct. at 451.49 While the legislative history of Title VII is largely uninstructive with respect to seniority rights, it is evident to us that Congress did not intend that a per se violation of the Act occur whenever females and minority group persons are disadvantaged by reverse seniority layoffs.50 See United States v. Jacksonville Terminal Co., 451 F.2d 418, 445 (5th Cir. 1971), cert. denied, 406 U.S. 906, 92 S.Ct. 1607, 31 L.Ed.2d 815 (1972).
Accordingly, we hold that a seniority clause providing for layoffs by reverse order of seniority is not contrary to public policy and welfare and consequently is not subject to modification by court decree.
IV. Evidentiary Considerations
To this point we have concluded that: (1) the seniority provisions of the Company’s collective bargaining agreement are not inconsistent with any provision of the conciliation agreement; and (2) the seniority provisions do not offend public policy.
There remains for our consideration the effect that evidence of discrimination may have upon laying off workers in reverse order of seniority. We turn to evidentiary considerations at this juncture because: (1) evidence appears in the record indicating disparate impact on the employment of female and [706]*706minority group workers,51 cf. Western Addition Community Organ, v. N. L. R. B., 485 F.2d 917 (D.C.Cir. 1973), cert. granted, 415 U.S. 913, 94 S.Ct. 1487, 39 L.Ed.2d 446 (1974); and (2) we are obliged to furnish directions to the district court with respect to evidence, if any, it may receive concerning those issues which remain for resolution.
Consequently we must answer the following questions: (1) what evidence, if any, may be adduced in the district court; (2) to what issue is such evidence to be directed? Depending upon the answers to the preceding questions, the ultimate question in this proceeding becomes: assuming, arguendo, evidence of past discrimination, is judicial modification permitted of facially neutral plant-wide seniority provisions where these provisions operate to the disadvantage of female and minority group workers?
We are not concerned here with allegations or proof that the Company’s plant-wide seniority system is by its express terms and intent presently discriminatory. Nor are we concerned with any charges or proofs that this plant-wide seniority system, which is facially neutral, was intended and designed to disguise present discriminatory practices.52 The only challenge to the validity of the Company’s plant-wide seniority system is that the seniority system, although facially neutral, nevertheless violates Title VII in that it operates to carry forward the effect of prior acts of discrimination. If evidence were to be permitted in support of such a theory, see Watkins, supra note 48, it could, at best, demonstrate that past discrimination occurred, and that the effects of such past discrimination are perpetuated by the present layoff practices under the current plant-wide seniority system. As we explain below, proofs of this nature are without probative value in challenging a bona fide seniority system. We believe that Congress intended to bar proof of the “perpetuating” effect of a plant-wide seniority system as it regarded such systems as “bona fide”.53 Congress, while recognizing that a bona fide seniority system might well perpetuate past discriminatory practices, nevertheless chose between upsetting all collective bargaining agreements with such provisions and permitting them despite the perpetuating effect that they might have. We believe that Congress intended a plant-wide seniority system, facially neutral but having a disproportionate impact on female and minority group workers, to be a bona fide seniority system within the meaning of § 703(h) of the Act.
To effectuate this intent, the only evidence probative in a challenge to a plant-wide seniority system would be evidence directed to its bona fide character; that is, evidence directed either to the néutrality of the seniority system or evidence directed to ascertaining an intent or design to disguise discrimination.54 As such, it is not fatal [707]*707that the seniority system continues the effect of past employment discrimination. We believe this result was recognized and left undisturbed by Congress in its enactment of § 703(h) and (j).55 Although the Congressional statements which we set out were made prior to the adoption of the Act in its final form and therefore were not addressed to the explicit language of § 703(h), these statements nonetheless were directed to the effect of seniority systems with which § 703(h) is concerned. As such, we believe they are of primary assistance in interpreting congressional intent as to seniority systems.56
The Interpretive Memorandum of Senators Clark and Case, floor managers for the Title VII bill in the Senate, in pertinent part provided:
Title VII would have no effect on established seniority rights. Its effect is prospective and not retrospective. Thus, for example, if a business has been discriminating in the past and as a result has an all-white working force, when the title comes into effect the employer’s obligation would be simply to fill future vacancies on a nondiscriminatory basis. He would not be obliged — or indeed, permitted— to fire whites in order to hire Negroes, or to prefer Negroes for future vacancies, or, once Negroes are hired, to give them special seniority rights at the expense of the white workers hired earlier. (However, where waiting lists for employment or training are, prior to the effective date of the title, maintained on a discriminatory basis, the use of such lists after the title takes effect may be held an unlawful subterfuge to accomplish discrimination.) (emphasis supplied)
110 Cong.Rec. 7213 (April 8, 1964). This interpretation of the interaction of Title VII with the “last hired, first fired” principle of employment seniority was repeated in Senator Clark’s response to written questions posed by Senator Dirk-sen:
Question. Would the same situation prevail in respect to promotions, when that management function is governed by a labor contract calling for promotions on the basis of seniority? What of dismissals? Normally, labor con[708]*708tracts call for ‘last hired, first fired.’ If the last hired are Negroes, is the employer discriminating if his contract requires that they be first fired and the remaining employees are white?
Answer. Seniority .rights are in no way affected by the bill. If under a ‘last hired, first fired’ agreement a Negro happens to be the ‘last hired,’ he can still be ‘first fired’ as long as it is done' because of his status as ‘last hired’ and not because of his race.
Question. If an employer is directed to abolish his employment list because of discrimination what happens to seniority?
Answer. The bill is not retroactive, and it will not require an employer to change existing seniority lists.
110 Cong.Rec. 7217 (April 8, 1964). See also id. at 6996 (April 6, 1964). Moreover, a memorandum from the Department of Justice presented by Senator Clark similarly interpreted the legislation’s effect upon layoffs made pursuant to a system of reverse order of seniority:
Title VII would have no effect on seniority rights existing at the time it takes effect. If, for example, a collective bargaining contract provides that in the event of layoffs, those who were hired last must be laid off first, such a provision would not be affected in the least by title VII. This would be true even in the case where owing to discrimination prior to the effective date of the title, white workers had more seniority than Negroes. Title VII is directed at discrimination based on race, color, religion, sex or national origin. It is perfectly clear that when a worker is laid off or denied a chance for promotion because under established seniority rules he is low man on the totem pole he is not being discriminated against because of his race. Of course, if the seniority rule itself is discriminatory, it would be unlawful under Title VII. If a rule were to state that all Negroes must be laid off before any white man, such a rule could not serve as the basis for a discharge subsequent to the effective date of the title. . . . But, in the ordinary case, assuming that seniority were built up over a period of time during which Negroes were not hired, these rights would not be set aside by the taking effect of Title VII. Any differences in treatment based on established seniority rights would not be based on race and would not be forbidden by the title. 110 Cong.Rec. 7207 (April 8, 1964). (emphasis supplied).
Our interpretation of the legislative history of Title VII (i. e., that Congress did not intend the chaotic consequences that would result from declaring unlawful all seniority systems which may disadvantage females and minority group persons, see, e. g., United States v. Jacksonville Terminal Co., 451 F.2d at 445,) has been adopted by other courts as well. The Fifth and Seventh Circuits agree with our view of the legislative history even though they considered this question in the more traditional procedural context of a Title VII proceeding.57 In Waters v. Wisconsin Steel Works, 502 F.2d 1309 (7th Cir. 1974), the Seventh Circuit stated:
An employment seniority system embodying the “last hired, first fired” principle does not of itself perpetuate past discrimination. To hold otherwise would be tantamount to shackling white employees with a burden of a past discrimination created not by them but by their employer. Title VII was not designed to nurture such reverse discriminatory preferences. Griggs v. Duke Power Co., 401 U.S. 424, 430-A31 [91 S.Ct. 849, 28 L.Ed.2d 158] (1971).
[709]*709502 F.2d at 1320. In Papermakers Local 189 v. United States, 416 F.2d 980 (5th Cir. 1969), cert. denied, 397 U.S. 919, 90 S.Ct. 926, 25 L.Ed.2d 100 (1970), the Fifth Circuit reasoned:
No doubt, Congress, to prevent ‘reverse discrimination’ meant to protect certain seniority rights that could not have existed but for previous racial discrimination. For example a Negro who had been rejected by an employer on racial grounds before passage of the Act could not, after being hired, claim to outrank whites who had been hired before him but after his original rejection, even though the Negro might have had senior status but for the past discrimination. As the court pointed out in Quarles. [Quarles v. Phillip Morris, 279 F.Supp. 505, E.D.Va.] the treatment of ‘job’ or ‘department seniority’ raises problems different from those discussed in the Senate debates: ‘a department seniority system that has its genesis in racial discrimination is not a bona fide seniority system.’ 279 F.Supp. at 517.
It is one thing for legislation to require the creation of fictional seniority for newly hired Negroes, and quite another thing for it to require that time actually worked in Negro jobs be given equal status with time worked in white jobs. To begin with, requiring employers to correct their pre-Act discrimination by creating fictional seniority for new Negro employees would not necessarily aid the actual victims of the previous discrimination. There would be no guaranty that the new employees had actually suffered exclusion at the hands of the employer in the past, or, if they had, there would be no way of knowing whether, after being hired, they would have continued to work for the same employer. In other words, creating fictional employment time for newly-hired Negroes would comprise preferential rather than remedial treatment. The clear thrust of the Senate debate is directed against such preferential treatment on the basis of race. That sentiment was codified in an important portion of Title VII, § 703(j):
‘(j) Nothing contained in this sub-chapter shall be interpreted to require any employer, employment agency, labor organization, or joint labor-management committee subject to this subchapter to grant preferential treatment to any individual or to any group because of the race, color, religion, sex, or national origin of such individual or group on account of an imbalance which may exist with respect to the total number or percentage of persons of any race, color, religion, sex, or national origin employed by any employer, referred or classified for employment by any employment agency or labor organization, admitted to membership or classified by any labor organization, or admitted to, or employed in, any apprenticeship or other training program, in comparison with the total number of percentage of persons of such race, col- or, religion, sex, or national origin in any community, State, section, or other area, or in the available work force in any community, State, section, or other area.’ 42 U.S.C. § 2000e-2(j) ....
We conclude, in agreement with Quarles, that Congress exempted from the anti-discrimination requirements only those seniority rights that gave white workers preference over junior Negroes. This is not to say that Whitfield [Whitfield v. United States Steelworkers, Local 2708, 5 Cir., 263 F.2d 546] and Quarles and Title VII prohibit an employer from giving compensatory training and help to the Negro workers who have been discriminated against. Title VII’s imposition of an affirmative duty on employers to, undo past discrimination permits compensatory action for those who have suffered from prior discrimination. Papermakers Local 189, 416 F.2d at 994-995. (emphasis supplied).
[710]*710We thus conclude in light of the legislative history that on balance a facially neutral company-wide seniority system, without more, is a bona fide seniority system and will be sustained even though it may operate to the disadvantage of females and minority groups as a result of past employment practices. If a remedy is to be provided alleviating the effects of past discrimination perpetuated by layoffs in reverse order of seniority, we believe such remedy must be prescribed by the legislature and not by judicial decree.
Having reached this conclusion our analysis is complete. Here, with the meager record before us and considering the manner in which the issues are framed, we need not, and indeed could not, decide whether any different result would obtain in an action brought by an aggrieved party58 were the requisite burden of proof sustained. See note 54, supra-, and generally Alexander v. Gardner-Denver Co., supra. What we decide here can obviously affect and bind only the parties present in this litigation. Of the parties before us, none has offered evidence to prove that the seniority provisions are not bona fide.
Having ascertained no basis in the record, or as a matter of law, to sustain the partial summary judgment order of September 23, 1974 as it pertains to the subject of layoffs, we will remand to the district court with directions: (1) to vacate so much of the September 23, 1974 order as is inconsistent with this opinion; and (2) to conduct such further proceedings not inconsistent with this opinion as may thereafter be required.
Each party will bear its own costs.
