UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA

MBALAMINWE MWIMANZI, Plaintiff,

v. Civil Action No. 25-102 (TJK)

DISTRICT OF COLUMBIA et al., Defendants.

MEMORANDUM OPINION

Mbalaminwe Mwimanzi pleaded guilty in the Superior Court of the District of Columbia to violating a civil protection order and was sentenced to 75 days incarceration (suspended) and one year of probation. But eight months later, when his probation was revoked and the sentence of incarceration imposed, Mwimanzi was detained, transported from court to the D.C. Jail, searched and processed for several hours, and then released because he had been credited serving more than the 75 days. Mwimanzi sues the District of Columbia, the U.S. Marshals Service, and the U.S. Department of Justice for his detention and search, which he alleges violated his Fourth and Fifth Amendment rights. Defendants move to dismiss on several grounds. For the reasons explained below, the Court will grant the motion and dismiss the case. I. Background In May 2023, Mwimanzi pleaded guilty in D.C. Superior Court to violating a civil protec-

tion order. ECF No. 27 at 4.1 The court imposed a suspended sentence of 75 days incarceration,

1 For simplicity’s sake, the Court cites the District of Columbia’s opposition for the uncontested summary of the relevant Superior Court proceedings. See ECF No. 27. The Court takes independent judicial notice of the information on the underlying Superior Court docket, which can be found at United States v. Mwimanzi, 2022 DVM 973. See Whiting v. AARP, 637 F.3d 355, 364

along with one year of probation. Id. In February 2024, the court revoked Mwimanzi’s probation and imposed the 75-day sentence. Id. Mwimanzi alleges that at that time he “had already accrued . . . at least 86 days” of “verifiable time-served credits,” and those credits should have satisfied his sentence. ECF No. 26 ¶ 12. Still, Mwimanzi alleges, he was “seized” by U.S. Marshals, “placed . . . in restraints,” and “transported . . . to the D.C. Jail.” Id. ¶ 14. Then, at the D.C. Jail, no official “perform[ed] an immediate verification of [his] release eligibility before initiating the standard custodial intake process.” Id. ¶ 16. Thus, he was “compelled to undergo the full intake procedure designed for inmates beginning incarceration,” which “included being held, processed, ordered to strip naked before officers, and forced to submit to a visual body cavity inspection.” Id. ¶¶ 17–18. Only after he had completed the intake procedure—lasting “several hours”—was Mwimanzi’s “completed-sentence status confirmed” and he was released. Id. ¶¶ 20–21.

Mwimanzi initially sued the D.C. Department of Corrections, the U.S. Marshals Service, and the U.S. Department of Justice for violations of the Fifth and Eighth Amendments, as well as under the Federal Tort Claims Act. See ECF No. 1 at 2–4. He filed two motions for leave to amend, which the Court granted. First, Mwimanzi merely sought to correct an erroneous date. See ECF No. 12 at 1. Then the Department of Corrections moved to dismiss, arguing that it could not be sued in its own name. See ECF No. 17. So in Mwimanzi’s second amended complaint— the one at issue now—he replaced the Department of Corrections with the District of Columbia and alleges only violations of the Fourth and Fifth Amendments. See ECF No. 26. The factual basis for these constitutional violations is the Defendants’ alleged failure to conduct “immediate

(D.C. Cir. 2011) (permitting judicial notice when ruling on a motion to dismiss); Veg-Mix, Inc. v. U.S. Dep’t of Agric., 832 F.2d 601, 607 (D.C. Cir. 1987) (permitting judicial notice of court records ).

sentence verification procedures” to account for Mwimanzi’s “time-served credits,” which led to his “seizure,” “overdetention,” and “unlawful search.” Id. ¶¶ 23–40.

Defendants move to dismiss in two separate motions. The District of Columbia argues that constitutional claims against it brought under 42 U.S.C. § 1983 must be dismissed under Federal Rule of Civil Procedure 12(b)(6) because Mwimanzi failed to adequately allege that his injuries were caused by a municipal policy. See ECF No. 27 at 6–10 (citing Monell v. Dep’t of Soc. Servs. of New York City, 436 U.S. 658, 694–695 (1978)). The Marshals Service and the Department of Justice—together, the “Federal Defendants”—argue that the claims against them must be dis- missed as well because Mwimanzi lacks a cause of action to sue. See ECF No. 33 at 7–10 (citing Bivens v. Six Unknown Named Agents of Fed. Bureau of Narcotics, 403 U.S. 388 (1971)). II. Analysis

A. Claims Against the District of Columbia Must Be Dismissed Because Mwimanzi Has Not Adequately Alleged a D.C. Municipal Policy

To survive a motion to dismiss under Federal Rule of Civil Procedure 12(b)(6), a complaint must “state a claim to relief that is plausible on its face.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007). That is, the complaint must contain “factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). When suing a “municipality under section 1983,” the factual content pled must contain both a “predicate constitutional violation and that a custom or policy of the municipality caused the violation.” Blue v. District of Columbia, 811 F.3d 14, 18 (D.C. Cir. 2015) (cleaned up). In other words, “D.C. is not liable under § 1983 for injuries ‘inflicted solely by its employees or agents’”; instead, “a city policy or practice” must have “cause[d] an injury.” Givens v. Bowser, 111 F.4th 117, 122 (D.C. Cir. 2024) (quoting Monell, 436 U.S. at 694).

A plaintiff can adequately plead a municipal policy in one of four ways: by identifying “(1)

an official policy explicitly adopted by D.C., (2) actions by a D.C. policymaker with final decision- making authority, (3) repeated behavior by D.C. municipal employees that have reached the level of a custom, or (4) a failure to act by D.C. that shows deliberate indifference to the potential for such violations.” Givens, 111 F.4th at 122. In addition to “plead[ing] facts that plausibly support one of those four types of municipal policies,” a plaintiff must plead “the elements” of that type. Id. And which type the plaintiff is pleading should be relatively clear; it is “not [the Court’s] role” to “try to surmise which theory of municipal liability has the strongest support in the complaint.” Id. (quoting Blue, 811 F.3d at 20).

Mwimanzi’s barebones second amended complaint does not adequately plead a District of Columbia municipal policy. While the complaint includes many factual allegations about how Mwimanzi was treated, it contains essentially no factual allegations that show that his treatment was caused by such a policy. Mwimanzi alleges that the failure to immediately verify his time- served credits and the resulting “constitutional violations suffered” were not on account of “a mere clerical error but the result of systemic failures and unconstitutional policies” from the District. ECF No. 26 ¶¶ 22, 28. He identifies three such policies: a “Policy/Custom” of “Fail[ing] to im- plement procedures that mandate immediate verification of release eligibility,” a “Policy/Custom” of “Uniform[ly] appl[ying] of invasive intake procedures, to all individuals, irrespective of their release eligibility,” and a “Policy/Custom” of “Fail[ing] to adequately train and supervise [Depart- ment of Corrections] personnel regarding the prompt identification and release of individuals with completed sentences.” Id. ¶ 22.
