Before LOURIE, CHEN, and STOLL, Circuit Judges. Case: 24-2190 Document: 39 Page: 2 Filed: 03/24/2026
CHEN, Circuit Judge. Ms. Debra Blackwell appeals from a United States Court of Federal Claims (Claims Court) grant of summary judgment denying her claim under the Equal Pay Act (EPA), 29 U.S.C. § 206(d)(1), that she was allegedly paid less than a male colleague for working overtime. Blackwell v. United States, 171 Fed. Cl. 682 (2024) (Decision). Apply- ing the test outlined in Corning Glass Works v. Brennan, 417 U.S. 188, 195 (1974), the Claims Court determined that Ms. Blackwell failed to demonstrate that her position and her colleague’s position required “equal skill, effort, and re- sponsibility” and were “performed under similar working conditions.” The Claims Court also determined that, even if Ms. Blackwell had made a prima facie showing of a vio- lation of the EPA, the government adequately rebutted her claim. Because we agree with the Claims Court that Ms. Blackwell did not raise a genuine dispute of material fact as to her prima facie case and, in any event, the gov- ernment successfully raised its affirmative defense, we af- firm. BACKGROUND Since 2004, Ms. Blackwell has worked as a Supervisory Program Manager in the U.S. Department of Homeland Se- curity, Customs and Border Patrol (Agency). Decision, 171 Fed. Cl. at 684. Her home office is the Agency’s Office of Field Operations, located in Houston, Texas (Houston Field Office). Id. Her position falls within the 340 – Program Management Series1 and is classified as a GS-14 pay grade. Id. at 684–85.
1 During the pendency of the litigation, the Agency conducted a “desk audit” which determined that Ms. Black- well’s position should be reclassified from 340 – Program Management Series to 1801 – Supervisory Immigration Case: 24-2190 Document: 39 Page: 3 Filed: 03/24/2026
BLACKWELL v. US 3
The scope of Ms. Blackwell’s position includes manag- ing twenty-seven border security programs, supervising a three-person team, interpreting Agency policy, communi- cating with stakeholders, and counseling supervisors and staff on immigration and nationality law and admissibility decisions. Id.; see also id. at 689. Ms. Blackwell’s tour of duty is Monday through Friday from 7:30 AM to 4:00 PM. Ms. Blackwell periodically is asked to work after-hours as needed. See J.A. 208 [18:11–18]. This work consists of fielding phone calls and replying to emails from her super- visors. Mr. Jeremy Luczkowski is a federal employee who works as a Border Security Coordinator in the same Hou- ston office as Ms. Blackwell. Decision, 171 Fed. Cl. at 685. His position falls within the 1895 – Customs and Border Protection Series and is also classified as a GS-14 pay grade. Id. Additionally, the position is covered by the Cus- toms Officer Pay Reform Act (COPRA), 19 U.S.C. § 267, which requires overtime compensation paid at two times the basic hourly rate for work that is “officially assigned” and exceeds 8 hours in a day or 40 hours in a week. Id. The scope of Mr. Luczkowski’s position includes coordi- nating more than thirty-nine enforcement programs, su- pervising a four-person team, overseeing eighteen officers in various task forces, and counseling for the Federal Emergency Management Agency’s (FEMA) Incident Com- mand System, National Incident Management System, and Continuity Operations. Decision, 171 Fed. Cl. at 685. Mr. Luczkowski’s expertise in emergency management re- sults in his “frequent deployments to national and interna- tional operations away from the Houston Field Office.” Id. (quoting J.A. 362 ¶ 9).

Mr. Luczkowski’s tour of duty is the same as Ms. Blackwell’s—Monday through Friday from 7:30 AM to 4:00PM. Id. Between 2018 to 2019, Mr. Luczkowski was deployed to the CBP Baltimore Field Office to support Hur- ricane Florence operations as the Operations Section Chief; Eagle Pass and Del Rio, Texas to mitigate a border crisis; and San Diego, California to serve as the Logistics Section Chief during Operation Secure Line. Id. at 685–86. Mr. Luczkowski recorded and earned overtime compensa- tion for these deployments. Mr. Erik Shoberg, Assistant Director of Field Opera- tions, is the direct supervisor for both Ms. Blackwell and Mr. Luczkowski. In 2019, Mr. Shoberg took a brief absence and Ms. Blackwell took over his duties, serving as acting Assistant Director of Field Operations. Id. at 686. While reviewing overtime cap waiver requests in her acting As- sistant Director role, Ms. Blackwell learned Mr. Luczkow- ski earned approximately $45,000 in overtime compensation under COPRA in 2019 for emergency man- agement response duties. Id. On September 13, 2019, Ms. Blackwell filed an admin- istrative grievance seeking compensation for “ten hours of overtime work per week for the last several years.” Id. Mr. Shoberg denied her request in March 2020 because (1) she had not been ordered nor approved to perform the weekly overtime work; (2) her duties differed substantially from Mr. Luczkowski’s; and (3) she had not provided docu- mentation supporting her claim. Id. Mr. Shoberg encour- aged Ms. Blackwell to search for and submit records that corroborated her request. Id. In response, Ms. Blackwell filed a formal grievance which was denied by the Agency on April 9, 2020. Id. Ms. Blackwell filed a complaint on September 18, 2020 in the United States District Court for the Southern Dis- trict of Texas; the case was later transferred to the Claims Court with both parties’ consent. Id. at 687. Case: 24-2190 Document: 39 Page: 5 Filed: 03/24/2026
BLACKWELL v. US 5
Ms. Blackwell’s complaint requested compensation under the EPA and COPRA “for loss of promotional potential, rep- utation, lost wages, [and] lost job benefits she would have received.” Id. (alteration in original). The government moved for partial dismissal of her claims. Id. On January 21, 2022, the Claims Court dismissed Ms. Blackwell’s EPA claim for overtime allegedly earned before September 18, 2018, because the statute of limita- tions precluded claims accruing before that date, and dis- missed Ms. Blackwell’s COPRA claim because that statute did not cover her employment position.

BLACKWELL v. US 5
Ms. Blackwell’s complaint requested compensation under the EPA and COPRA “for loss of promotional potential, rep- utation, lost wages, [and] lost job benefits she would have received.” Id. (alteration in original). The government moved for partial dismissal of her claims. Id. On January 21, 2022, the Claims Court dismissed Ms. Blackwell’s EPA claim for overtime allegedly earned before September 18, 2018, because the statute of limita- tions precluded claims accruing before that date, and dis- missed Ms. Blackwell’s COPRA claim because that statute did not cover her employment position. Blackwell v. United States, No. 21-1075, 2022 WL 2315088, at *4, *6 (Fed. Cl. Jan. 21, 2022). After a period of discovery, the government filed a sum- mary judgment motion which the Claims Court granted. In its decision, the Claims Court determined that Ms. Blackwell had fallen short in her prima facie case. The Claims Court determined that Mr. Luczkowski was an “in- apt comparator” because Ms. Blackwell’s and Mr. Lucz- kowski’s jobs required (1) different skills, (2) different effort, (3) different responsibilities, and (4) different work- ing conditions. Decision, 171 Fed. Cl. at 689–90. The Claims Court also found that the government had success- fully raised an affirmative defense. Id. at 690. Ms. Blackwell timely appealed. We have jurisdiction under 28 U.S.C. § 1295(a)(3). DISCUSSION “[W]e review a grant of summary judgment by the Court of Federal Claims de novo.” Anderson v. United States, 23 F.4th 1357, 1361 (Fed. Cir. 2022) (citation omit- ted). The EPA codifies “the principle of equal pay for equal work regardless of sex.” Boyer v. United States, 97 F.4th 834, 839 (Fed. Cir. 2024) (quoting Corning Glass, 417 U.S. at 190). In order to make a prima facie case of violation of Case: 24-2190 Document: 39 Page: 6 Filed: 03/24/2026
the EPA, a plaintiff must show “that an employer pays dif- ferent wages to employees of opposite sexes ‘for equal work on jobs the performance of which requires equal skill, ef- fort, and responsibility, and which are performed under similar working conditions.’” Corning Glass, 417 U.S. at 195 (quoting 29 U.S.C. § 206(d)(1)). To survive summary judgment, Ms. Blackwell need only raise a genuine dispute of material fact as to whether Mr. Luczkowski is a proper comparator. See First Com. Corp. v. United States, 335 F.3d 1373, 1379 (Fed. Cir. 2003); RCFC 56(a). “Once established, the burden of proof shifts to the em- ployer to prove that the differential is made pursuant to one of the four affirmative defenses[:]” “(i) a seniority sys- tem; (ii) a merit system; (iii) a system which measures earnings by quantity or quality of production; or (iv) a dif- ferential based on any other factor other than sex.” Boyer, 97 F.4th at 839, 841 (citations omitted). I. Prima Facie Case Ms. Blackwell’s prima facie case for her EPA claim rests solely on Mr. Luczkowski as her comparator. In ad- dition to contesting the Claims Court’s “skill” and “effort” analysis, Ms. Blackwell argues that the Claims Court erred by finding Mr. Luczkowski had differing responsibilities. The Claims Court concluded that Ms. Blackwell’s and Mr. Luczkowski’s responsibilities materially differed be- cause—in addition to supervising individuals and oversee- ing CBP programs—Mr. Luczkowski oversaw “four special task forces.” Decision, 171 Fed. Cl. at 690. Further, the Claims Court noted that during Mr. Luczkowski’s overtime deployments, he led “special assignments.” Id. Ms. Blackwell does not dispute the Claims Court’s de- termination that Mr. Luczkowski’s task force and special assignment responsibilities are not similar to any of her job responsibilities. Rather, she highlights their similar peo- ple management roles and notes responsibilities unique to Case: 24-2190 Document: 39 Page: 7 Filed: 03/24/2026
BLACKWELL v. US 7
her position that she believes make up for everything else. This argument is unavailing. Ms. Blackwell is correct that she and Mr. Luczkowski both supervise a small team of CBP employees (teams of three and four, respectively) and manage a similar volume of border security programs (twenty-seven and thirty-nine, respectively). See id. at 684–85. However, in Mr. Luczkow- ski’s task force work, he oversees an additional eighteen officers to which Ms. Blackwell offers nothing comparable. The same is true for Mr. Luczkowski’s special assignment responsibilities. Ms. Blackwell’s attempts to make up for that divergence in responsibilities merely emphasize that their jobs are indeed different. See Appellant Reply Br. 7 (highlighting that, unlike Mr. Luczkowski, Ms. Blackwell’s position “required meeting with consultants, contractors, and/or business executives in the private sector” (internal quotation marks and citation omitted)). Ms. Blackwell also argues that the Claims Court erro- neously determined Ms. Blackwell and Mr. Luczkowski were subject to different working conditions. We disagree. The Claims Court reasoned that Ms. Blackwell’s and Mr. Luczkowski’s working conditions were different be- cause, in addition to being primarily stationed at the Hou- ston Field Office, Mr. Luczkowski also performed duties while “working outdoors, in emergency situations, and in adverse conditions with the possibility of physical attacks.” Decision, 171 Fed. Cl. at 690. Ms. Blackwell contends that Mr. Luczkowski’s lack of testimony that he experienced danger on the job or “chased down people of interest” indicates his role possesses no “possibility of physical attacks.” Appellant Br. 19–20. Without providing a cite, she further insists that Mr. Lucz- kowski’s San Diego deployment “was performed in a hotel room, making car and hotel reservations.” Appellant Reply Br. 9. Case: 24-2190 Document: 39 Page: 8 Filed: 03/24/2026
Even assuming arguendo that Ms. Blackwell’s allega- tions are true, she does not address that at least some of the time, Mr. Luczkowski was deployed, outdoors, in a dif- ferent location than the Houston Field Office. In contrast, Ms. Blackwell testified that she had never been assigned to do work outside of the Houston Field Office. See J.A. 310 [141:10–16]. Moreover, Mr. Luczkowski’s deployments were the source of his overtime pay; the entirety of Ms. Blackwell’s overtime pay claims consist of work she did in the Houston Field Office. Therefore, Ms. Blackwell can- not show her job and Mr. Luczkowski’s job, and more spe- cifically their overtime assignments, are “performed under similar working conditions.” Corning Glass, 417 U.S. at 195. Because Ms. Blackwell must demonstrate each ele- ment articulated in Corning Glass for her prima facie case, see Moore v. United States, 66 F.4th 991, 996–97 (Fed. Cir. 2023) (en banc), and she has failed to do so, we do not fur- ther address her arguments related to equal skill and ef- fort. II. Affirmative Defense The Claims Court further determined that, even if Ms. Blackwell could demonstrate a prima facie case, the government nonetheless had also sufficiently established an affirmative defense: that the pay disparity between Ms. Blackwell and Mr. Luczkowski was due to differing statutory and regulatory schemes. The Claims Court noted that Mr. Luczkowski’s overtime pay was governed by COPRA, while Ms. Blackwell’s overtime pay was governed by Title 5, which permits overtime compensation for work that is “officially ordered or approved” and “performed by an employee” in excess of 8 hours in a day or 40 hours in an administrative workweek. 5 U.S.C. § 5542(a); 5 C.F.R. § 550.111(a). According to the Claims Court, because Ms. Blackwell had not proven that she performed the Case: 24-2190 Document: 39 Page: 9 Filed: 03/24/2026
BLACKWELL v. US 9
overtime work, as was required under Title 5, the govern- ment had shown the pay differential was justified. Ms. Blackwell argues she did perform the overtime work by highlighting her total email traffic in 2018 and 2019 as evidence. See Appellant Br. 22–23. From the email traffic, she “estimate[s] ten hours of work performed per week.” Id. She also states that her overtime work included phone calls. This argument must fail. Because Ms. Blackwell makes no showing that she actually performed the over- time work she says she has done, she cannot rebut the gov- ernment’s affirmative defense. The record does support Ms. Blackwell’s claim that she performed some overtime work in the relevant period. See, e.g., J.A. 212 [34:5–35:2] (Mr. Shoberg testimony indicating Ms. Blackwell worked overtime during a 2019 conference). However, she did not contemporaneously record her work and has no call records to support the extra time—despite claiming that her over- time work included fielding phone calls. Instead, she offers evidence about her total email vol- ume in 2018 and 2019 and claims that “her expertise” al- lows her to convert those emails into overtime hours. This is not enough. Ms. Blackwell does not compare her email volume in 2018 or 2019 to years she did not work overtime or discuss how many of those emails she sent or received after her normal tour of duty. She offers no conversion of her email volume to overtime pay beyond mere speculation. Yet another problem with her argument is that overtime pay must be “officially ordered or approved.” See Lesko v. United States, 161 F.4th 1352, 1358 (Fed. Cir. 2025) (en banc) (citing 5 U.S.C. § 5542(a)). Ms. Blackwell has not produced evidence that any of her alleged overtime work was officially ordered or approved. Thus, we agree with the Claims Court that the government has sufficiently raised an affirmative defense to Ms. Blackwell’s EPA claim. Case: 24-2190 Document: 39 Page: 10 Filed: 03/24/2026
CONCLUSION We have considered Ms. Blackwell’s remaining argu- ments and find them unpersuasive. For the foregoing rea- sons, we affirm. AFFIRMED
