JOHN F. LEHMAN, JR., SECRETARY OF THE NAVY, ET AL., PETITIONERS V. YVONNE G. TROUT, ET AL. No. 83-706 In the Supreme Court of the United States October Term, 1983 The Solicitor General, on behalf of the Secretary of the Navy and the Commanding Officer of the Navy Regional Data Automation Center, petitions for a Writ of Certiorari to review the judgment of the United States Court of Appeals for the District of Columbia Circuit in this case. Petition for a Writ of Certiorari to the United States Court of Appeals for the District of Columbia Circuit PARTIES TO THE PROCEEDINGS The petitioners are John F. Lehman, Jr., Secretary of the Navy, and Capt. James C. Richardson, Jr., Commanding Officer of the Navy Regional Data Automation Center. The named respondents representing the class are Clara A. Perlingiero and Yvonne G. Trout. In addition, the individual claims of Marie Bach, Charlene Hardy, and Joan S. Creighton were consolidated with the class action in the district court, and Bach's appeal was consolidated with the class action in the court of appeals. Hardy and Creighton did not appeal from the court of district court's denial of their claims; Trout's individual appeal was rejected and this Court denied her individual petition for certiorari on April 18, 1983 (No. 82-1429). TABLE OF CONTENTS Opinions below Jurisdiction Statute involved Statement Reasons for granting the petition Conclusion Appendix A Appendix B Appendix C OPINIONS BELOW The opinion of the court of appeals (App., infra, 1a-39a) is reported at 702 F.2d 1094. The opinion of the district court (App., infra, 40a-70a) is reported at 517 F. Supp. 873. JURISDICTION The judgment of the court of appeals was entered on March 11, 1983. Rehearing was denied on May 31, 1983 (App., infra, 73a). The time for filing a petition for a writ of certiorari was extended to and including October 28, 1983, by Justice Brennan on August 15, 1983. The jurisdiction of this Court is invoked under 28 U.S.C. 1254(1). STATUTE INVOLVED Section 717(a) of Title VII of the Civil Rights Act of 1964, 42 U.S.C. (Supp. V) 2000e-16(a), provides in pertinent part: All personnel actions affecting employees or applicants for employment * * * in military departments as defined in section 102 of Title 5, * * * shall be made free from any discrimination based on race, color, religion, sex, or national original. QUESTIONS PRESENTED 1. Whether, in light of this Court's subsequent decision in United States Postal Service Board of Governors v. Aikens, No. 81-1044 (Apr. 4, 1983), the court of appeals erred in affirming the judgment of the district court despite concluding that the statistical analysis upon which that court had relied in finding discrimination in violation of Title VII of the Civil Rights Act of 1964, as amended (42 U.S.C. 2000e et seq.), included data that could not form a basis for imposing liability. Our primary submission is that, because of the errors in the district court's analysis identified by the court of appeals, no violation of Title VII has been established under the standard prescribed in Aikens, and the judgment of the court of appeals should accordingly be summarily vacated and the case remanded for reconsideration in the light of Aikens. If this Court nevertheless decides to set this case for plenary review, two additional questions are presented: 2. Whether intentional discrimination is established in a class action suit involving professional technical positions by a statistical analysis that fails to account adequately for minimum objective qualifications for those positions. 3. Whether, in remedial hearings after a class-wide violation of Title VII has been found, the burden shifts to the employer to demonstrate "by clear and convincing evidence" that its employment decisions with regard to particular individuals were based on legitimate, non-discriminatory factors. STATEMENT 1. Four cases involving individual and class sex discrimination claims under Title VII were brought against petitioners (the Secretary of the Navy and the Commanding Officer of the Navy Regional Data Automation Center) and consolidated for trial in the United States District Court for the District of Columbia. Respondents' class allegations were that the Navy intentionally discriminated in employment practices against "all female professional technical employees employed by the (Naval Command Support Activity) 'NAVCOSSACT' or the (Navy Regional Data Automation Center) 'NARDAC" at any time between June 6, 1972 and June 4, 1979." /1/ App., infra, 41a. The employees involved performed computer-related tasks. At trial, respondents relied on a computerized multiple regression analysis to show that women received lower salaries than men, in an attempt to show women were paid less than one would expect in the absence of discrimination. A multiple regression analysis is a statistical technique designed to estimate the effects of several independent variables on a given result. Properly used, such an analysis can show how much influence factors such as sex, experience, and education had on perceived disparities in salary levels. Here, the independent variables included in respondents' study were the following: (1) level (but not type) of formal education, (2) years between date of last education and entry into the federal service -- in effect, the age at which the employee was hired, (3) length of service (but not type of service) with NAVCOSSACT and NARDAC, and (4) length of service (but not type of service) with the federal government. App., infra, 6a. After accounting for these four variables, the analysis attributed the remaining salary differences to the sex of the employees considered. Based on this analysis, which reflects the effects of pre-1972 actions on salaries within the plaintiff class as well as the effects of actions taken by agencies other than NAVCOSSACT and NARDAC, respondents' expert concluded that there was statistically significant adverse treatment of women at NAVCOSSACT and NARDAC. Petitioners introduced evidence to show that this conclusion resulted from certain flaws in respondents' analysis, including the fact that respondents' study relied on data regarding employment decisions that could not form the basis of Title VII liability. /2/ Accordingly, petitioners' evidence excluded -- and was the only evidence to exclude -- employment decisions that the court of appeals ultimately held were not actionable -- i.e., the effect of pre-1972 actions and initial placement decisions. See page 6, infra,. /3/ On the basis of this evidence, petitioners contended that when such irrelevant factors as pre-1972 actions and initial placement decisions were eliminated and persons with comparable computer experience were compared, women advanced in a statistically indistinguishable way from men. 2. Following a trial, the district court ruled that petitioners had discriminated against the class of women professional technical employees in initial grade placement and promotions, basing its finding largely on the regression analysis presented by respondents. /4/ Essential to the district court's ultimate conclusion was its rejection of two arguments made by petitioners. First, the court ruled (App. infra, 46a-48a) that petitioners' objection to respondents' failure to distinguish between pre- and post-1972 actions was not valid because discrimination occurring before 1972 "even if coupled with neutral employment practices since then, produced actionable continuing discriminatory effects after 1972 * * *." /5/ Second, the court rejected (App., infra, 48a) petitioners' contention that respondents' regression analyses were flawed because they placed responsibility on petitioners for decisions regarding initial placement of employees when hired by, or transferred to, NAVCOSSACT and NARDAC. /6/ Applying similar reasoning, the district court also rejected petitioners' statistical analyses, in large part because they did not take into account pre-1972 discrimination, App., infra, 57a, and because they "assumed that the employees studied were placed in an appropriate salary grade at the outset, and (the analyses) therefore could not and did not detect any bias in the hiring and placement process." App., infra, 56a (footnote omitted). Relying on its conclusion that pre-1972 actions and initial placement decisions were actionable, the district court concluded that respondents' multiple regression analysis established a prima facia case, and that "applying the burden-of-production rule articulated by the Supreme Court in (Texas Department of Community Affairs v.) Burdine, (450 U.S. 248 (1981),) * * * the (petitioners) have not rebutted (respondents') prima facie case of discrimination" (App., infra, 59a). 3. A divided court of appeals (MacKinnon, J., dissenting) affirmed in part and reversed in part the district court's ruling on the class claims presented in this case. It reversed the district court's holding that petitioners, rather than other federal agencies responsible for formulating federal personnel regulations, were responsible for determining the grade levels of new employees. /7/ The appellate court also ruled that the district court's theory for permitting the inclusion of pre-1972 statistics in respondents' analysis "is flatly inconsistent with the Supreme Court's pronouncements in Hazlewood School District v. United States, 433 U.S. at 309-10, * * * and United Air Lines, Inc. v. Evans, 431 U.S. 553, 558 (1977)" (App., infra, 15a-16a). Notwithstanding these rulings, the court of appeals affirmed the district court's decision that respondents had established a prima facie case that petitioners had violated Title VII with regard to promotions (App., infra, 17a-18a) and that petitioners had not rebutted that case (App., infra, 18a-19a). /8/ The court acknowledged (App., infra, 16a) that, because they group nonactionable employment decisions with actionable ones, respondents' analyses "hold the potential for some distortion"; it nonetheless concluded that respondents had established a prima facie case because their analyses "included a substantial amount of data covering post-1972 employment decisions affecting class members." /9/ The court of appeals also affirmed the district court's decision regarding the burden of proof that would be placed on the employer in remedial hearings held to determine liability to individual class members. Reiterating its ruling in McKenzie v. Sawyer, 684 F.2d 62, 76-78 (D.C. Cir. 1982), the court held (App., infra, 21a-22a): "Because such class members are presumptively entitled to relief upon showing that they were potential victims of the defendants' discriminatory practices * * * the defendants must 'rebut the plaintiffs' individual showing by clear and convincing evidence'. McKenzie, 685 F.2d at 78." Judge MacKinnon dissented from the majority's imposition of class-wide liability. He argued that the district court had incorrectly allocated the burden of proof by requiring defendants to "disprove the plaintiffs' allegations" (App., infra, 29a; emphasis in original). Moreover, he concluded (id. at 31a) that the district court "was so concerned with the allocation of the 'stages' of proof, focusing upon whether the plaintiffs established a prima facie case and whether the defendant rebutted that case, that it lost sight of the basic principle that plaintiffs were ultimately required to prove intentional discrimination by a preponderance of the evidence." Petitioners filed a petition for rehearing, suggesting rehearing en banc. The court of appeals denied the petition, with Judges Tamm, Wilkey, MacKinnon and Bork dissenting (App., infra, 75a). REASONS FOR GRANTING THE PETITION The outcome of most Title VII litigation involving class-wide claims of discrimination is determined by the court's evaluation of statistical evidence and analyses. It is, therefore, crucial that such evidence be carefully analyzed, bearing in mind that the ultimate responsibility of the court is to apply the substantive principles of law underlying Title VII and, as this Court emphasized in United States Postal Service Board of Governors v. Aiken, supra, to determine whether, at the conclusion of the trial, plaintiffs have established that they have been discriminated against in violation of Title VII. The uncritical acceptance of statistical evidence, without regard to settled principles of law carefully developed by Congress and this Court's prior decisions, will inevitably undermine the objectives of Title VII. The courts below imposed liability relying on a statistical analysis whose conclusion was based, in critical part, on evidence that did not relate to employment decisions actionable under Title VII. The data offered in this case showed only that women in respondent's class generally occupy lower pay levels than men in a unit of the Navy that has recently increased substantially the number of its women employees, with resultant added concentration of women at trainee and entry level positions. The district court and the court of appeals rendered their decision before Aikens was decided, and committed the same fundamental error as the lower courts in Aikens. /10/ Had the court of appeals focused "directly on the question of discrimination," Aikens, slip. op. 5, and decided whether plaintiffs, at the conclusion of the evidence, had established the existence of discriminatory employment practices, it would necessarily have concluded that there was no basis for affirming the district court's imposition of liability. The foundation of the district court's evaluation of the evidence was simply swept away by the court of appeals' ruling that the effects of pre-1972 actions and initial placement decisions could not form the basis for imposing liability. The district court relied on statistical evidence that factored in employment decisions that the court of appeals specifically found could not form the basis for imposing liability under Title VII, and rejected petitioners' statistical evidence precisely because it excluded such decisions. Once the court of appeals corrected those errors in the district court's legal analysis, there remained no reliable evidence upon which the appellate court could properly conclude that respondents had established, with respect to the class claims, any violation of Title VII by petitioners. Accordingly, the court of appeals should have either reversed the district court's decision or remanded the case to the district court for an evaluation of all the evidence under correct legal standards. Pullman-Standard v. Swint, 456 U.S. 273, 292 (1982). The district court and the court of appeals agreed that the determination of whether defendants had engaged in class-wide discrimination "revolves primarily around the statistics submitted by the parties and the analysis of the statistics by the parties' experts" (App., infra, 42a, 6a). Statistical evidence "must be regarded with a substantial degree of caution," Pegues v. Mississippi State Employment Service, 699 F.2d 760, 766 (5th Cir. 1983), petition for cert. pending, No. 83-139, because the usefulness of statistics "depends on all the surrounding facts and circumstances." International Brotherhood of Teamsters v. United States, 431 U.S. 324, 340 (1977). No valid conclusions regarding petitioners' employment practices can be drawn unless the statistical evidence is analyzed in accordance with legally correct interpretations of substantive Title VII Law. See Pegues, 669 F.2d at 767-768; Pouncy v. Prudential Insurance Co. of America, 668 F.2d 795, 803 (5th Cir. 1982); Wilkins v. University of Houston, 654 F.2d 388, 395 (5th Cir. 1981). In this case, the court of appeals premised liability on statistics which admittedly were not meaningfully tied to correct legal principles. When analyzed in light of those principles and of the government's evidence revealing their flaws, those statistics simply do not show that NAVCOSSACT and NARDAC discriminated against women in promotions during the relevant time frame. Yet the court of appeals, repeating the same error that court had made in Aikens, based its decision on whether respondents' evidence was adequate to establish a prima facie case in the absence of evidence by the government proving the flaws in respondents' statistical presentation (App., infra, 10a-21a; Cf. id. at 31a-33a (dissenting opinion). It is undisputed that the women in respondents' class in general occupy lower pay grades than men. It is, however, both erroneous and contrary to the purposes of Title VII for a court to leap from that fact alone to the conclusion that discrimination has caused the disparity. Recent recruitment efforts have brought more members of previously under-represented groups into the federal workforce in technical fields such as the computer operations involved here. /11/ Substantial numbers of women and minorities are accordingly necessarily clustered in entry level positions, and are paid accordingly. Until these inexperienced workers gain the requisite experience and training, and until vacancies occur at higher level positions, it cannot legitimately be expected that minorities and women will be equally distributed throughout an agency's workforce. See Valentino v. United States Postal Service, 674 F.2d 56, 72 n.29 (D.C. Cir. 1982). Unwarranted speculation, such as that of the court below, that the disparity between the numbers of men and women in higher level positions is the result of discrimination penalizes agencies for recruiting women and minorities at entry-level positions, thereby discouraging such recruitment efforts and, in the long run, tending to decrease the opportunities of these groups for advancement in new fields. Moreover, the court of appeals' substantive rulings entirely eliminated the legal basis for the district court's conclusion that respondents' regression analysis established facts necessary to impose liability on petitioners. The court of appeals correctly ruled that two critical components of respondents' analysis were not legally relevant. First, it held that the district court had erred in ruling that petitioners' pre-1972 actions "even if coupled with neutral employment practices since then, produced actionable continuing discriminatory effects after 1972" (App., infra, 47a). As this Court said in United Air Lines v. Evans, 431 U.S. 553, 558 (1977) (emphasis in original): "the emphasis should not be placed on mere continuity; the critical question is whether any present violation exists." Accordingly, here as in Evans, where the present system is neutral, pre-1972 acts of discrimination, alone, do not convert it into a violation of Title VII. Second, the court of appeals properly concluded that petitioners had established at trial "that initial grade placements were made by either the CSC (Civil Service Commission) or the OPM (Office of Personnel Management) or by employing agencies that were not made defendants in this case" (App., infra, 17a). /12/ There was thus no basis for holding defendants here responsible for initial placement decisions. The inclusion of data regarding pre-1972 actions and initial placement decisions necessarily rendered respondents' regression analysis, and the district court's conclusions based on it, unreliable. See EEOC v. Federal Reserve Bank, 698 F.2d 633, 645 (4th Cir. 1983), petition for cert. pending sub. nom. Cooper v. Federal Reserve Bank, No. 83-185. Liability cannot be premised upon the results of a multiple regression analysis that inextricably intertwines the effects of actionable employment decisions with the effects of nonactionable employment decisions. It is not possible to isolate the portion of such results, if any, attributable to decisions on which liability may properly be grounded. The statistical results upon which the trial court relied reflected without differentiation the combined effects of three factors: (1) timely promotion decisions upon which it would be legally permissible to premise liability; (2) untimely promotion decisions upon which it would not be legally permissible to premise liability; and (3) timely and untimely initial placement and decisions of others upon which it would not be legally permissible to premise petitioners' liability. Based on the evidence relied upon by the trial court, it is not legally or logically possible to determine which, if any, portion of the combined results of these three factors is due to personnel actions upon which liability can be based. Indeed, the district court specifically stated that there was "(n)o practical method of separating the effects of pre-1972 and post-1972 discrimination in regression analysis" (App., infra, 48a n.20); but see note 14, infra. /13/ It was, therefore, improper for the court of appeals to hold without further refinement or analysis that the relevant evidence established an inference of discrimination sufficient to carry respondents' burden of proof. Wilkins v. University of Houston, 662 F.2d 1156, 1157 (5th Cir. 1981). Under Pullman-Standard v. Swint, 456 U.S. 273, 292 (1982), a remand is required where the district court findings are rendered unreliable by an erroneous view of the law, such as the district court exhibited here, unless "the record permits only one resolution of the factual issue." See also United States Postal Service Board of Governors v. Aikens, supra. The evidence in this record when evaluated under the correct legal standards regarding the effects of pre-1972 actions and initial placement decisions does not permit the conclusion that the trier of the fact would be required to resolve the issues in respondents' favor. Thus, the state of the record required the court of appeals to remand the case to the district court for further proceedings under proper legal standards. In Aikens, this Court ordered remand because "we cannot be certain that (the district court's) findings of fact in favor of the Postal Service were not influenced by its mistaken view of the law" (slip op. 5). In the instant case, the district court's acceptance of respondents' statistics and its rejection of petitioners' statistics are expressly based upon the very legal errors recognized by the court of appeals (pages 3-6, supra). Accordingly, the principle of Aikens, a fortiorari, requires a remand to the district court here. /14/ The courts below rendered their decisions prior to Aikens. The court of appeals' decision cannot stand in light of this Court's direction in Aikens that all of the evidence must be evaluated at the conclusion of the case in order to determine whether plaintiffs carried their burden of establishing by a preponderance of the evidence that defendants intentionally discriminated against them. We therefore submit that the court of appeals' decision should be summarily vacated and the case remanded with appropriate directions for further proceedings. /15/ CONCLUSION The judgment of the court of appeals should be vacated and the case remanded for further consideration in light of United States Postal Service Board of Governors v. Aikens, supra. REX E. LEE Solicitor General J. PAUL MCGRATH Assistant Attorney General CAROLYN B. KUHL ROBERT E. KOPP Attorneys OCTOBER 1983 /1/ NAVCOSSACT was responsible for the Chief of Navy Operations' computer activities in the 1960's and 1970's. Among its duties were the development and operation of highly classified computer programs and systems relating to national defense. These activities included wargaming, telecommunications, and strategic command and control. The name of NAVCOSSACT was changed to NARDAC on March 17, 1977, when the Navy effected a major reorganization of its data processing activities. In order to consolidate these activities, data-processing personnel and support resources of the Navy Materiel Command Support Activity, the Navy Accounting and Finance Center and the Naval District, Washington, D.C., were transferred to NARDAC. /2/ To eliminate the effects of pre-1972 actions and actions taken by employees other than NAVCOSSACT/NARDAC, petitioners ran the same regressions used by respondents, but only for those employees hired by petitioners after 1972. In no year for which those regressions were run (1974-1979) was sex a statistically significant variable. Def. Exh. 204, at 4-6, Def. Exh. 205; Tr. 1427-1432, 1436-1437, 1500-1506. /3/ This evidence included an extensive "cohort analysis" that grouped men and women who started at NAVCOSSACT and NARDAC at the same GS level at similar times and compared their advancements. In addition, applicant flow data presented by petitioners showed that women applying for promotions from September 1976 to 1979 had statistically the same treatment with regard to promotions as did their male counterparts. In addition, petitioners filed a motion for reconsideration after trial based upon new statistical analyses. These new analyses were intended to further clarify two points: (1) an evaluation of NAVCOSSACT and NARDAC personnel files showed that women who were initially placed at NAVCOSSACT and NARDAC had 49% of the computer experience of men, and the generally lower initial placement level of women simply reflected their relative lack of computer experience; and (2) any showing of adverse treatment of women was eliminated when initial placement and time-barred acts were removed from the regression analyses. The district court rejected this evidence as untimely. /4/ The court also considered five individual claims, ruling in favor of respondents on two and against them on the remaining three claims. The court of appeals affirmed the district court's finding of discrimination against the two individuals, but modified the relief awarded. We do not challenge the rulings regarding the individual claims in this petition. /5/ The court stated that it knew of no practical method of separating the effects of pre-1972 and post-1972 discrimination in a regression analysis (App., infra, 48a n.20). /6/ The district court also rejected petitioners' contention that respondents' regression analysis failed to account adequately for the minimum necessary objective qualifications of the positions at issue. That is, petitioners contended that the fundamental cause for the mistaken notion that sex discrimination caused the salary disparity between men and women in NAVCOSSACT and NARDAC was the failure of respondents' analyses to account for differences in computer-related experience. The district court rejected this argument on the ground that respondents' variables were sufficiently accurate to establish a prima facie case. App., infra, 49a-52a. /7/ In accordance with that determination, the court of appeals concluded that "the District Court erred in holding that the class was entitled to relief for discriminatory initial placements" (App., infra, 17a; emphasis in original). /8/ The court of appeals' opinion focuses almost exclusively on the statistical evidence presented. Without discussion, it notes that "the District Court properly considered the statistical and nonstatistical evidence on a cumulative basis in assessing the strength of the (respondents') prima facie case." App., infra, 6a n.7. /9/ Regarding petitioners' objection that respondents' analyses ignored the minimum objective qualifications necessary for placement and promotion in the professional technical job series at issue, the court ruled (App., infra, 12a-14a) that respondents' variables were closely enough related to years of computer experience to provide an adequate basis for inferring disparate treatment. /10/ In our petition for rehearing, we called the court's attention to Aikens and its application to this case. /11/ Evidence at trial (Def. Exh. 198, at 1-18; Tr. 1409-1425) showed that the selection of women for trainee positions at NAVCOSSACT/ NARDAC generally compared favorably with their availability at the appropriate grade level both nationally and locally: Grade 5 7 9 Total New Hires (1/1/72-3/12/72) 26 64 16 % Female Representation 38.46 42.19 18.75 Nationwide % Female Availability 20.88 18.91 17.33 Wash., D.C. % Female Availability 27.09 24.28 21.97 /12/ The grade (i.e., salary) levels of persons entering the federal service are determined in accordance with OPM (formerly CSC) regulations that take account of relevant education and experience. Similarly, OPM regulations limit the extent to which a persons' grade level may be increased on a transfer from one agency to another. See generally 5 C.F.R. Pts. 300-351. /13/ The district court made no finding that promotion decisions alone were discriminatory, because it believed, contrary to the court of appeals' ruling, that petitioners had control over initial placement decisions. Indeed, the district court specifically rejected defendants' extensive statistical evidence, which focused on promotions and showed no adverse treatment of class members, because that evidence did not deal with initial placement. (App., infra, 55a n.40, 59a n.47.) /14/ The respondents' multiple regression analysis could then be rerun using a model that factors out the effects of irrelevant employment decisions (i.e., decisions occurring prior to March 24, 1972, and decisions relating to initial placement at time of hire). This can be easily accomplished with the simple addition of a variable to the respondents' model that accounts for grade or salary as of March 24, 1972, and for grade or salary at initial placement for those placed after March 24, 1972. See Finklestein, The Judicial Reception of Multiple Regression Studies in Race and Sex Discrimination Cases, 80 Colum. L. Rev. 737, 745-746 (1980). While we would not oppose affording respondents a further opportunity for evidentiary development in light of the court of appeals' clarification of the governing legal standards, we submit that, in fairness, the government should also be given the opportunity to submit additional evidence, such as that submitted with our motion for reconsideration. See note 3, supra. We submit that such evidence will establish that women at NAVCOSSACT and NARDAC have received as many promotions and advanced as similarly situated men at all relevant times. /15/ In light of this submission, we do not urge that the Court grant plenary review in order to consider the two additional questions we have presented. We do not, on balance, believe that these questions present issues requiring plenary consideration at this time. Should the Court set the case for briefing and argument, however, we believe that these additional questions should also be considered, in order to present the case in its full factual and legal context. The Court recognized in Hazelwood School District v. United States, 433 U.S. 299, 308 (1977), that when special qualifications are required to fill the jobs at issue, the relevant statistical comparisons must be among those who possess these qualifications. Here, respondents' regression analysis failed to account for such qualifications, since it did not factor in computer-related experience as an independent variable. The court below concluded (App., infra, 14a) that the independent variable of length of employment with NAVCOSSACT/NARDAC was a valid proxy for such experience. That conclusion overlooks the fact that the grade level at which a class member is initially placed when joing NAVCOSSACT/NARDAC reflects her computer-related experience before coming to the agency. All respondents' independent variables relevant to that initial placement (education, length of government service and, essentially, age) ignore that experience. The class members had significantly less computer-related experience; that relative lack of experience was not adequately reflected in respondents' regression analysis. The court of appeals followed its prior practice in imposing a heightened burden of proof on the employer at the remedial stage of Title VII litigation. It held that after a class member shows she has been adversely affected, the employer must rebut the presumption of discrimination by "clear and convincing evidence" establishing a legitimate business reason for the adverse action. App., infra, 21a-22a; McKenzie v. Sawyer, 684 F.2d 62, 78 (D.C. Cir. 1982). This ruling is consistent with the practice in the Seventh and Fifth Circuits (Stewart v. General Motors Corp., 542 F.2d 445, 453 (7th Cir. 1976), cert. denied, 433 U.S. 919 (1977); Lee v. Washington County Board of Education, 625 F.2d 1235, 1239 (5th Cir. 1980)), but it conflicts with the practice in the Fourth Circuit, where the employer may justify his actions by a simple preponderence of the evidence. Sledge v. J. P. Stevens, 585 F.2d 625, 637 (1978), cert. denied, 440 U.S. 981 (1979); EEOC v. American National Bank, 652 F.2d 1176, 1201 (4th Cir. 1981). Petitioners are defendants placed in the unusual posture of having the burden of proof shifted to them at the remedial stage. The shift of the burden is, we submit, clearly adequate to protect the interests served by Title VII under the ordinary "preponderance of the evidence" standard. See International Brotherhood of Teamsters v. United States, 431 U.S. 324, 362 (1977); California v. Mitchell Brothers' Santa Ana Theater, 454 U.S. 90, 93 (1981); Herman & MacLean v. Huddleston, Nos. 81-680 & 81-1076 (Jan. 24, 1983). Appendix Omitted
