Opinion

UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA

EUGENE NYAMBAL,

Plaintiff,

v. Civil Action No. 14 - 1904 (LLA) ALLIED BARTON SECURITY SERVICES, LLC,

Defendant.

MEMORANDUM OPINION

The matter is before the court on a motion for summary judgment filed by Defendant

AlliedBarton Security Services, LLC (“AlliedBarton”), ECF No. 338, a cross-motion for summary

judgment filed by Plaintiff Eugene Nyambal, ECF No. 350, and several miscellaneous motions

filed by Mr. Nyambal, including a motion to certify for interlocutory appeal, ECF No. 347;

motions to remove filing restrictions, ECF Nos. 355, 373; motions for reconsideration, ECF

Nos. 371, 372, 374, 378; motion for leave to file amended complaint, ECF No. 375; and motions

to compel, ECF Nos. 384, 390, 393. Mr. Nyambal claims that AlliedBarton defamed him by

posting his name and picture on the World Bank’s “Do No Admit” list and denying him access to

the World Bank. ECF No. 1-3 ¶¶ 10, 13, 29-32. Upon consideration of the motions and supporting

documentation, the court will grant AlliedBarton’s motion for summary judgment, deny

Mr. Nyambal’s cross-motion for summary judgment, and deny Mr. Nyambal’s remaining motions

as moot. I. FACTUAL BACKGROUND

The following facts are undisputed.1 Mr. Nyambal was employed as a senior advisor at

the International Monetary Fund (“IMF”) until 2009. ECF No. 338-2 ¶ 1; ECF No. 1-3 ¶ 1; ECF

No. 350, at 74.2 In his role, he advised member countries during economic aid negotiations and

safeguarded IMF resources on behalf of its shareholders. ECF No. 338-2 ¶ 2; ECF No. 350, at 74.

While at the IMF, Mr. Nyambal raised concerns about alleged corruption and misuse of IMF funds

in connection with a mining project in Cameroon. ECF No. 338-2 ¶ 3; ECF No. 1-3 ¶ 6. In

June 2009, Mr. Nyambal’s employment at the IMF was terminated without notice or explanation.

ECF No. 338-2 ¶ 4; ECF No. 350, at 74.

AlliedBarton served as the World Bank’s security contractor in 2013. ECF No. 338-2 ¶ 7;

ECF No. 338-10, at 4. Part of AlliedBarton’s responsibilities included “[f]acilitat[ing] the entry

of authorized persons by providing identification credentials and verifying same” and

“[d]eter[ring], prevent[ing] or detect[ing] the entry of unauthorized persons.” ECF No. 338-2 ¶ 8;

ECF No. 350, at 97 (contractual provision). In October 2013, AlliedBarton denied Mr. Nyambal

access to the World Bank because he was on the Bank’s “Do Not Admit” list. ECF No. 338-2

¶¶ 6, 14; ECF No. 1-3 ¶¶ 13, 16.

The following facts are hotly disputed. AlliedBarton maintains that it did not compile the

“Do Not Admit” list and had no part in Mr. Nyambal’s placement on the list. ECF No. 338-2

¶¶ 9-12; ECF No. 350, at 75-76 (Mr. Nyambal’s objections). Instead, the IMF sent the World

1 Although Mr. Nyambal raises several objections to AlliedBarton’s “Statement of Material Facts Not in Dispute,” see generally ECF No. 350, the court considers AlliedBarton’s proffered facts undisputed to the extent that Mr. Nyambal relies on the same facts in his complaint, ECF No. 1-3, and in his response to AlliedBarton’s statement of material facts, ECF No. 350, at 72-78. 2 Page numbers cited in this memorandum opinion are those generated by CM/ECF.

2 Bank a list of names for inclusion on the “Do Not Admit” list, including Mr. Nyambal’s, as part

of a routine update to the list. ECF No. 338-2 ¶¶ 13-15, ECF No. 338-7, at 2-4 (email transmitting

list); compare ECF No. 1-3 ¶ 16 (Mr. Nyambal’s allegation that “the World Bank . . . shared with

Nyambal the IMF’s blacklisting memo”), with ECF No. 350, at 77 (“Mr. Nyambal OBJECTS to

th[e] asserted fact” that “[t]he World Bank confirmed that Mr. Nyambal’s name was on the Do

Not Admit list as provided by the IMF to the World Bank Corporate Security in advance of the

Annual meetings of 2013.”).

II. PROCEDURAL HISTORY

In October 2014, Mr. Nyambal sued AlliedBarton in the Superior Court of the District of

Columbia. ECF No. 1-3. AlliedBarton removed the action to this court under 28 U.S.C. § 1441.

ECF No. 1. In his complaint, Mr. Nyambal alleged that AlliedBarton and the IMF had conspired

to retaliate against him and that AlliedBarton had engaged in tortious interference with his business

relationships, defamation, and intentional infliction of emotional distress. ECF No. 1-3 ¶¶ 22-35.3

In January 2016, the court dismissed the suit in full. ECF Nos. 14, 15. Mr. Nyambal

subsequently filed a motion for reconsideration on the defamation claim, ECF No. 17, which the

court granted in October 2018, ECF Nos. 41, 42. Since his defamation claim was subject to a one-

year statute of limitations, the court restricted Mr. Nyambal’s discovery to events that occurred

between October 2013 and October 2014. ECF No. 42, at 4 n.2. The parties concluded discovery

on April 1, 2022. See Dec. 2, 2021 Minute Order. In September 2023, the court permitted

3 Mr. Nyambal unsuccessfully sued the IMF and the Secretary of the Treasury for causes of action premised on the same underlying facts. Order, Nyambal v. Int’l Monetary Fund, No. 19-7152 (D.C. Cir. Nov. 20, 2020) (affirming the notice of voluntary dismissal filed by Plaintiff’s counsel); Nyambal v. Mnuchin, 245 F. Supp. 3d 217 (D.D.C. 2017) (granting the Secretary’s motion to dismiss for lack of subject-matter jurisdiction and failure to state a claim).

3 AlliedBarton to late-file its answer to the complaint, because the company had inadvertently failed

to file it earlier in the case and there was no basis to hold it in default. ECF No. 308; Sep. 30, 2023

Minute Order. In December 2023, the case was reassigned to the undersigned. Docket,

No. 14-CV-1904 (D.D.C. Dec. 14, 2023). In late 2024 and early 2025, the parties briefed cross-

motions for summary judgment. ECF Nos. 338, 350, 353, 354, 356. The motions are now ripe

for consideration.

III. LEGAL STANDARD

Under Federal Rule of Civil Procedure 56, “[a] party is entitled to summary judgment only

if there is no genuine issue of material fact and judgment in the movant’s favor is proper as a matter

of law.” Soundboard Ass’n v. Fed. Trade Comm’n, 888 F.3d 1261, 1267 (D.C. Cir. 2018) (quoting

Ctr. for Auto Safety v. Nat’l Highway Traffic Safety Admin., 452 F.3d 798, 805 (D.C. Cir. 2006));

see Fed. R. Civ. P. 56(a). A material fact is one which “might affect the outcome of the suit under

the governing law,” and a “dispute about a material fact is ‘genuine,’” when “the evidence is such

that a reasonable jury could return a verdict for the nonmoving party.” Anderson v. Liberty Lobby,

Inc., 477 U.S. 242, 248 (1986). At summary judgment, the moving party bears the burden of

demonstrating “the absence of a genuine issue of material fact” in dispute, Celotex Corp. v. Catrett,

477 U.S. 317, 323 (1986), while the nonmoving party must present specific facts supported by

materials in the record that would be admissible at trial and that could enable a reasonable jury to
