What Are Pattern or Practice Claims in Civil Rights Cases Against Police Departments?

A pattern or practice claim is a civil rights lawsuit that targets a police department as an institution. It goes after the whole department, not just a single officer, for repeated, systemic violations of constitutional rights. Under 34 U.S.C. § 12601, only the U.S. Department of Justice or a state attorney general can bring these cases. Individual victims cannot file directly, but their cases contribute to the evidence.

If you have been hurt by the police in New York City, you may suspect your experience was not an isolated mistake. You may be right. The law recognizes that some constitutional violations are not one-off errors by one officer. They can be the predictable result of how an entire department trains, supervises, and disciplines its officers. Pattern or practice claims exist to address that systemic harm. This article explains what these claims are, who can bring them, how investigations work, and what they produce. It also explains how they relate to the individual lawsuit a New Yorker can file to recover compensation.

The Law Behind Pattern or Practice Claims: 34 U.S.C. § 12601

The federal authority for pattern or practice claims comes from a single statute. The relevant language of 34 U.S.C. § 12601 reads:

It shall be unlawful for any governmental authority, or any agent thereof, or any person acting on behalf of a governmental authority, to engage in a pattern or practice of conduct by law enforcement officers or by officials or employees of any governmental agency with responsibility for the administration of juvenile justice or the incarceration of juveniles that deprives persons of rights, privileges, or immunities secured or protected by the Constitution or laws of the United States.

In plain English, the statute gives the federal government the power to sue a police department for a pattern of unconstitutional conduct. It is not limited to prosecuting or suing the individual officers involved. It shifts the focus from "did this officer break the law?" to "does this department routinely produce constitutional violations?"

A few features of this law matter for anyone trying to understand it:

• It was originally enacted as 42 U.S.C. § 14141 as part of the Violent Crime Control and Law Enforcement Act of 1994, then later renumbered to its current section, 34 U.S.C. § 12601. You will still see the old citation in older court opinions and articles.
• It requires a pattern or practice, meaning conduct that is repeated, routine, or generalized. A single incident, no matter how serious, does not establish a pattern.
• It contains no private right of action. Only the Attorney General, acting for or in the name of the United States, may bring a civil action under § 12601. Individuals cannot sue under this statute themselves.

That last point is the most common source of confusion, so it is worth restating. A person harmed by police misconduct cannot personally file a pattern or practice lawsuit. What they can do is file their own individual civil rights case. Their experience can then become part of the evidence that supports a government investigation.

What Types of Police Misconduct Can Lead to a Pattern or Practice Claim?

Not every type of police conduct rises to the level of a pattern or practice claim. The government generally looks for categories of misconduct that recur across many incidents and many officers. In New York City, several of these categories have real, documented histories.

Excessive force that is routine rather than rare. When use-of-force incidents are frequent, poorly investigated, and rarely disciplined, they can form the basis of a pattern claim. The Orlow Firm has handled individual excessive-force cases that show the kind of harm these patterns produce. They include a $475,000 recovery for an emotionally disturbed woman shot in the face with a bean bag gun who lost an eye, and a $200,000 recovery for a teenager kicked in the face by NYPD officers who needed surgery for a jaw fracture. Prior results do not guarantee a similar outcome.

Unlawful stops, searches, and arrests. Stop-and-frisk is the canonical New York example. When stops are made without lawful basis on a large scale, they implicate the Fourth and Fourteenth Amendments.

Discriminatory policing based on race, national origin, gender, disability, or sexual orientation. Patterns that disproportionately target a protected group are a core focus of civil rights enforcement.

False arrests and fabricated evidence at scale. Isolated false arrests are individual claims. A department-wide practice of making arrests without probable cause can rise to a pattern.

Failure to discipline. Some departments tolerate or cover up misconduct through weak internal affairs processes or rubber-stamped use-of-force reviews. That culture is itself evidence of a pattern, because it shows the conduct is condoned rather than corrected.

Retaliation against complainants who report misconduct, which discourages accountability and entrenches the pattern.

Who Can File a Pattern or Practice Claim in New York?

This is where many New Yorkers are surprised. The people who can bring a pattern or practice lawsuit are limited, and they do not include the individuals who were harmed.

At the federal level, only the DOJ Civil Rights Division can sue a police department under § 12601. It investigates, issues findings, and either negotiates a reform agreement or files suit.

At the state level in New York, the New York Attorney General has parallel authority. Under New York's Executive Law and through the Law Enforcement Misconduct Investigative Office (LEMIO), the Attorney General can investigate and bring civil litigation. This authority covers any of the state's hundreds of covered law enforcement agencies. According to the 2025 LEMIO annual report, the office has received 456 referrals since inception, completed 207 of them, and reached a pattern or practice finding in 44 completed cases. In 2025 alone, the office completed 102 referrals and made 28 pattern findings.

Civil rights organizations, such as the ACLU, the Center for Constitutional Rights, and the NAACP Legal Defense Fund, do not file pattern or practice suits under § 12601 themselves. Instead, they gather evidence, support victims, document misconduct, and press the government to act. Their work often supplies the factual foundation an investigation needs.

Individuals cannot file a pattern or practice suit. But individual complaints, lawsuits, and testimony are exactly what feed these investigations. Your case can help demonstrate the pattern even though you are not the plaintiff in the systemic action.

One development changes the practical picture in 2025. The federal Department of Justice stepped back sharply from this kind of enforcement. In May 2025, the DOJ Civil Rights Division dismissed Biden-era police investigations and proposed consent decrees in Louisville and Minneapolis, and also closed investigations into departments in Phoenix, Trenton NJ, Memphis TN, Mount Vernon NY, and Oklahoma City OK. [LAWYER TO VERIFY: The brief also states the Trump DOJ dropped the NYPD Special Victims Division investigation. Search results indicate that investigation was opened in 2022 and was not listed among the formally closed cases in May 2025. Please confirm the current status of the SVD investigation against primary DOJ sources before publication.] The practical takeaway for New Yorkers is important. With federal enforcement in retreat, the New York Attorney General and LEMIO are now the primary enforcement backstop for systemic police accountability in the state.

How Is a Pattern or Practice Investigation Conducted?

A pattern or practice investigation is methodical and evidence-heavy. It typically unfolds in stages.

It usually begins with a trigger, such as complaints from the public, civil rights organizations, government officials, or media reporting. In some cases it begins with a mandatory referral. New York's Executive Law requires certain referrals to the Attorney General. One example is when an officer accumulates a defined number of complaints from multiple individuals within a set period.

Once opened, investigators conduct a broad review of data. That includes arrest records, use-of-force reports, body camera footage, internal affairs files, training materials, and disciplinary outcomes. They interview people at every level, including officers, command staff, community members, and advocates. They also conduct site visits and policy reviews.

The standard requires both statistical and anecdotal evidence. Numbers alone do not prove a constitutional violation, and individual stories alone do not prove a pattern. The two together do. When the investigation concludes, the government publishes a findings report. If it finds violations, negotiations toward a remedy begin.

What Are the Outcomes of a Successful Pattern or Practice Claim?

The outcomes of a pattern or practice case look very different from the outcome of a personal injury or civil rights lawsuit. The goal is institutional change, not individual compensation.

Common outcomes include:

• Consent decree: a court-approved reform plan enforced by a federal judge, often overseen by an independent monitor.
• Court-ordered policy changes, such as new use-of-force standards, training requirements, and disciplinary procedures.
• Independent oversight or a monitor. The long-running NYPD stop-and-frisk litigation is one example, where a federal monitor continues to oversee reform.
• Community involvement, such as advisory boards, public reporting requirements, and similar accountability measures.
• Settlement agreements. This is the model the New York Attorney General used in resolving the protest-policing case against the NYPD, with implementation continuing in phases.

It is just as important to understand what these outcomes do not include. A pattern or practice case does not put money in the pockets of individual victims. Compensation for an individual injury comes through a separate track. That track is an individual civil rights lawsuit under 42 U.S.C. § 1983, not § 12601.

How Do Pattern or Practice Claims Differ from Your Individual Civil Rights Lawsuit?

For most people harmed by police, the individual civil rights lawsuit is the case that actually matters to their lives. It is the one that can recover compensation. The table below shows how the two tracks differ.

The most important point for readers is that these two tracks are not mutually exclusive. Your individual lawsuit can proceed at the same time as a government investigation. In fact, your case can help demonstrate the very pattern an investigation is built to prove. The Orlow Firm handles the individual civil rights lawsuit track. That is the track where injured New Yorkers directly recover for what was done to them.

NYC in Focus: Real Pattern or Practice Cases

New York City has one of the most documented histories of pattern or practice litigation in the country. Grounding the concept in named cases shows how it works in practice.

Floyd v. City of New York (2013). In this landmark case, a federal judge found the NYPD liable for an unconstitutional stop-and-frisk practice that disproportionately targeted Black and Latino New Yorkers, violating the Fourth and Fourteenth Amendments. The court appointed a federal monitor, and reform has continued for years under that oversight. The case remains active, with the monitor still reporting on the department's progress. Floyd is the clearest local example of how a systemic finding produces court-supervised reform rather than individual payouts.

NYPD Special Victims Division (2022 DOJ investigation). The Department of Justice announced an investigation into how the NYPD's Special Victims Division handled sexual assault cases, examining whether survivors faced gender-biased policing. [LAWYER TO VERIFY: Please confirm the current status of this investigation — whether it remains open, has been formally closed by the Trump DOJ, or has been transferred to the NY Attorney General — against current primary sources before publication.]

New York Attorney General v. NYPD (protest policing). The Attorney General brought a case over the NYPD's handling of 2020 protests, alleging excessive force. The matter was resolved through a settlement announced in 2023, with the NYPD entering Phase II of implementation in October 2025. It is a concrete illustration of the state-level enforcement model now carrying more of the load in New York.

Mount Vernon, NY Police Department. The DOJ concluded a pattern or practice investigation of the Mount Vernon Police Department in early 2025, finding civil rights violations involving excessive force, illegal arrests, and unlawful searches. The Trump DOJ subsequently closed the investigation in May 2025 without pursuing a consent decree. [LAWYER TO VERIFY: Please confirm whether the NY Attorney General has taken any follow-on action regarding the Mount Vernon Police Department before publication.]

Frequently Asked Questions

What is the difference between a pattern or practice claim and a class action lawsuit?

A class action is brought by private individuals who sue on behalf of everyone similarly harmed, and it can seek money damages. A pattern or practice claim under § 12601 can only be brought by the government and seeks institutional reform, not damages for individuals. The two can overlap in subject matter but are different legal mechanisms with different plaintiffs and goals. Consult a civil rights attorney about which track fits your situation.

Can I file a complaint that helps trigger a DOJ or NY AG investigation?

Yes. While you cannot file the pattern or practice lawsuit yourself, your complaint, your lawsuit, and your testimony can all become evidence that supports an investigation. Investigators rely heavily on individual accounts to establish that misconduct is systemic. Documenting what happened to you and filing your own individual claim are among the most useful things you can do. Consult a civil rights attorney about how to preserve your account.

What happens if the DOJ drops an investigation?

When the federal government steps back, it does not erase the underlying misconduct or eliminate other avenues. In New York, the Attorney General and LEMIO retain independent authority to investigate and litigate systemic misconduct. Your individual right to sue under § 1983 is entirely separate and is not affected by what the DOJ decides to do. Consult a civil rights attorney to understand the options that remain available to you.

Does a consent decree protect me individually if police violate it?

No. A consent decree is designed to reform a department, not compensate any one person. If you are injured because officers violate constitutional standards the decree was meant to enforce, your remedy is still your own individual civil rights lawsuit. The decree may help establish that the department was on notice of a problem, but it does not substitute for your own claim. Consult a civil rights attorney about your specific situation.

How long does a pattern or practice investigation take?

There is no fixed timeline. These investigations involve reviewing years of records, many interviews, and analysis of both statistics and individual accounts. They commonly take well over a year and sometimes several years from opening to resolution. Negotiating a consent decree afterward adds more time. Because the process is slow and outside any individual's control, people who were harmed should not wait on an investigation to pursue their own claims.

What is a consent decree and who enforces it?

A consent decree is a court-approved agreement setting out specific reforms a police department must make — new training, revised use-of-force rules, stronger discipline. A federal judge enforces it, and an independent monitor typically oversees compliance and reports to the court. The decree stays in place until the department demonstrates lasting reform. Court enforcement gives it more weight than a voluntary policy change.

Can a pattern or practice case happen at the same time as my personal lawsuit?

Yes. The two tracks are independent and can run in parallel. A government investigation does not pause or absorb your individual claim, and your lawsuit does not interfere with the investigation. Your case can also help demonstrate the very pattern the government is investigating. The Orlow Firm handles the individual lawsuit track, which is where injured New Yorkers actually recover compensation. Consult a civil rights attorney about pursuing your own claim.

What is LEMIO and how is it different from the DOJ?

LEMIO is New York's Law Enforcement Misconduct Investigative Office, housed within the state Attorney General's office. It investigates misconduct across New York's covered law enforcement agencies and can bring civil litigation at the state level. The DOJ enforces federal civil rights law nationwide under § 12601; LEMIO operates under New York state law and focuses on New York agencies. With federal enforcement in retreat, LEMIO has become the more active systemic-accountability body in the state.
