asserting claims under the Age Discrimination in Employment Act, 29 U.S.C. § 633a (the

“ADEA”). 2 See Amended Complaint (“Am. Compl.”) ¶¶ 46–47, 52–59, ECF No. 21-2. The

plaintiff, a former employee of the Naval Criminal Investigative Services (“NCIS”), alleges that

the defendant discriminated against her by involuntarily transferring her from a position at the

The plaintiff further alleges that when she complained about the transfer and refused to report to

Naples, the defendant continued his discrimination and retaliated against her by transferring her

Spencer, pursuant to Federal Rule of Civil Procedure 25(d). 2 The plaintiff also brought an ADEA hostile work environment claim. See Amended Complaint (“Am. Compl.”) ¶¶ 48–51, ECF No. 21-2. However, on March 6, 2020, the Court granted the defendant’s Motion for Judgment on the Pleadings or, in the Alternative, for Summary Judgment, ECF No. 19, “to the extent it s[ought] to dismiss the plaintiff’s hostile work environment claim in Count One of the plaintiff’s Amended Complaint.” Order at 1 (Mar. 6, 2020), ECF No. 45. to Norfolk, Virginia and then Great Lakes, Illinois, which she alleges caused her to be

constructively discharged from the NCIS. Id. ¶¶ 32–33, 58. The plaintiff also alleges that the

defendant retaliated against her by cancelling her approved leave requests. Id. ¶¶ 31, 50.

On June 23, 2023, the Court issued a Memorandum Opinion granting the defendant’s

motion for summary judgment. See Memorandum Opinion at 1 (June 23, 2023), ECF No. 86.

The plaintiff appealed this Court’s dismissal to the Court of Appeals for the District of Columbia

Circuit, which vacated in part the Court’s decision and remanded the case for further

consideration of the parties’ submissions. Van Horn v. Del Toro, No. 23-5169, 2024 WL

4381186, at *1 (D.C. Cir. Oct. 3, 2024). On remand, the Court concludes for the following

reasons that it must grant in part and deny in part the defendant’s motion for summary judgment

2 facts that remain relevant to the resolution of this matter on remand. These facts are undisputed

unless otherwise noted. 4

The plaintiff began working for the NCIS as a special agent in 1987 and became eligible

for retirement “at the end of July 2012, when she would have 25 years of service [with the

NCIS].” 5 Am. Compl. ¶¶ 9–10. Throughout her employment with the NCIS, the plaintiff was

subject to the NCIS’s Mobility Program. Def.’s Facts ¶ 5. The NCIS’s Mobility Program

provides that it is “absolutely vital that [the] NCIS maintains a flexible workforce prepared to

respond to mission requirements wherever they may occur” and, to that end, “all new hires in the

[special agent] career field are required to sign a Mobility Agreement, acknowledging their

understanding that one or more overseas assignments and periodic transfers within [the

continental United States] will be required throughout their career.” Def.’s Mot. Exhibit (“Ex.”)

4 (Special Agent Career Program) at § 13-12.

In 2012, the plaintiff was assigned to the “Criminal Investigations Directorate at NCIS

Headquarters[,]” Def.’s Facts ¶ 3; see Pl.’s Facts at 2 ¶ 3. In January 2012, “[the] NCIS held a

meeting of Agency executives,” during which they “discussed [a] vacant Criminal ASAC

[‘Assistant Special Agent in Charge’] position in Naples, Italy.” Def.’s Mot. at 6 (citing id., Ex.

6 (Excerpts from Transcript of Deposition of John Hogan (“Hogan Tr.”)) at 68:13–19, ECF No.

75-7; id., Ex. 7 (Declaration of John Hogan (“Hogan Decl.”)) ¶¶ 6, 10, ECF No. 75-8). Five

special agents, ranging in age from 41 to 53, “voluntarily bid on the vacancy[,]” but the

4 The defendant argues that the Court should not consider some of the plaintiff’s factual statements because the plaintiff violated the Court’s General Order by not furnishing precise citations to the portions of the record on which she relies for those statements. Despite having had to expend an inordinate amount of time combing through the record to identify specific materials upon which the plaintiff relied, the Court will consider all of the parties’ submissions and resolve this matter on the merits based on its comprehensive review of the record. 5 NCIS agents like the plaintiff become eligible to retire after 25 years of service, but retirement is mandatory when NCIS agents turn 57-years old. See Am. Compl. ¶ 10.

3 defendant asserts that these five were not “the best fit for the Naples vacancy” for various

reasons. Id. According to the defendant, one of the candidates “lacked supervisory experience.”

Id. Another “had just completed an [Outside the Continental United States] [(‘]OCONUS[’)]

tour.” Id. at 7. The third candidate “was performing well in the Contingency Response Field

Office, a difficult to fill vacancy.” Id. at 8. The fourth candidate had recently completed an
