Civil RightsSection 1983Motion to DismissFirst Amendment
In one sentence

In Diallo v. New York City Police Department, Judge Preska denied amendment, granted dismissal of federal claims, and dismissed state claims without prejudice.

Who this affects

Ibrahima Diallo’s federal claims were dismissed, his request to amend was denied, and his remaining state-law claims were dismissed without prejudice. New York City and Westchester County prevailed on their dismissal motions; Westchester Medical Center may renew its motion in state court.

What happened

In Diallo v. New York City Police Department, Ibrahima Diallo alleged that police wrongly connected him to a robbery, arrested him, used excessive force, and mistreated him in jail. He also alleged discrimination based on his Guinean origin, interference with his Muslim prayers, defamation, and other wrongdoing.

The defendants argued that Diallo’s amended claims were legally insufficient. They relied in part on the victim’s identification of Diallo, the grand-jury indictment, and Diallo’s failure to allege facts showing unconstitutional conduct or a municipal policy. Diallo also asked to amend his complaint again and sought to strike a city filing.

Judge Loretta Preska denied Diallo’s motion to strike and his request to amend, granted New York City’s motion to strike Diallo’s letter, and granted Westchester County’s and New York City’s motions to dismiss the federal claims. The court dismissed the remaining state-law claims without prejudice and stated that Westchester Medical Center’s motion could be renewed in a competent state court.

Case
Diallo v. New York City Police Department · No. 1:23-cv-01238
Judge
Loretta Preska
Date
Feb. 18, 2025

Background

Ibrahima Diallo alleged that police connected him to a February 2018 robbery in Yonkers, New York. The victim, Rosa, identified Diallo in a photo array after detectives told him that the perpetrators were Guinean. Diallo alleged that he was the only Guinean person in the array. A grand jury indicted him in 2018, and officers arrested him in 2021. The criminal case was dismissed in October 2022 after the District Attorney’s Office stated that the quality of the evidence and the passage of time created a legal impediment to conviction.

Diallo alleged that officers used excessive force during his arrest despite his spinal tuberculosis. He also alleged that, during eight days in jail, he was strip-searched, isolated because officials mistakenly believed his condition was contagious, denied a prayer mat, and given inadequate medical treatment. His proposed second amended complaint asserted federal claims concerning malicious prosecution, defamation, false arrest and imprisonment, national-origin discrimination, religious exercise, and injunctive relief, along with state-law claims.

Motions and rulings

The court denied Diallo’s motion to strike New York City’s reply because, although the reply did not follow the required format, it was short and contained limited new material. The court granted New York City’s motion to strike Diallo’s letter because the letter functioned as an unauthorized response to the city’s reply. The court did not consider either letter further.

The court also denied Diallo’s motion for leave to file a second amended complaint. It held that the proposed amendments were futile because they did not add sufficient factual or legal allegations to create a claim that could survive dismissal. The court considered the pending motions against the proposed amended pleading.

Federal claims

The court granted Westchester County’s and New York City’s motions to dismiss Diallo’s federal claims. The opinion applied the pleading standard requiring enough facts to make a claim legally plausible. Because the claims against the municipalities arose under Section 1983, Diallo also had to allege a constitutional violation and facts connecting that violation to a municipal policy or custom.

For malicious prosecution, the court held that Diallo did not overcome the presumption of probable cause created by the grand-jury indictment. The victim had identified Diallo in a double-blind photo array, and the proposed complaint did not allege facts showing that the indictment resulted from fraud, perjury, suppressed evidence, or other police bad faith. The court concluded that the allegations showed weaknesses in the prosecution’s case but did not adequately allege intentional misconduct.

The court dismissed the defamation claims. It treated the claim against Westchester County as abandoned because Diallo did not address it in his opposition. As to New York City, the court held that Diallo did not identify a false statement. The photograph was of Diallo, and his allegation that it made him look like a criminal did not identify a false statement sufficient for a federal defamation claim.

The court dismissed the false-arrest and false-imprisonment claims for the same probable-cause reasons. Diallo did not allege facts rebutting the presumption arising from the indictment or showing that officials knowingly and intentionally made material false statements or omissions.

The court construed Diallo’s national-origin claim as a selective-enforcement claim under the Equal Protection Clause. It dismissed the claim because Diallo did not identify similarly situated people who were treated differently. His references to a hypothetical person named “John Smith,” New York City’s alleged history of discrimination, and the inclusion of Guinean images did not provide enough comparative information. The court also noted that the victim had identified Diallo.

The court dismissed the religious free-exercise claim concerning the strip search because Diallo did not allege facts showing that the search lacked a legitimate correctional purpose. As to the prayer mat, the court stated that Diallo adequately alleged a religious belief and burden at the pleading stage, but dismissed the claim because he did not adequately allege that the denial resulted from an official Westchester County policy or custom.

The court dismissed Diallo’s request for an order requiring New York City and Westchester County to remove his profile from criminal databases. It treated the claim as abandoned because Diallo did not respond to the defendants’ arguments supporting dismissal.

State-law claims and final disposition

After dismissing the federal claims, the court declined to exercise supplemental jurisdiction over the remaining state-law claims. It dismissed those claims without prejudice so they could be renewed in a proper state court. The court also dismissed Westchester Medical Center’s motion without prejudice to renewal in a state court of competent jurisdiction.

The final order denied Diallo’s motion to strike; granted New York City’s motion to strike Diallo’s letter; denied Diallo’s motion for leave to amend; granted Westchester County’s and New York City’s motions to dismiss the federal claims; and dismissed the remaining state-law claims without prejudice.
