Federal Judge in Brooklyn Dismisses Justice Department Lawsuit Against New York City's Sanctuary Laws
Judge Ramón Reyes Jr. ruled on Oct. 15 that the government lacked standing to challenge the city's ban on holding people for ICE, and that federal information-sharing laws cannot be used to force the city to share information. The Justice Department has lost similar suits in several other states and cities.
Two Rulings in One Order
On Thursday, Oct. 15, 2026, a federal judge in Brooklyn threw out the Trump administration's lawsuit against New York City's sanctuary laws[1][2]. These are city rules that limit how much the jails and police help U.S. Immigration and Customs Enforcement (ICE). U.S. District Judge Ramón Reyes Jr. dismissed United States v. City of New York[1][2].
The Justice Department filed the suit on July 24, 2025, in Brooklyn federal court. Eric Adams was mayor then[5][6]. The suit targeted city laws, including a 2011 provision that bars the Department of Correction from honoring ICE detainers. It also targeted NYPD rules that limit cooperation with immigration agents[5][6].
Reyes didn't rule one way on everything. He found the government lacked standing on the detainer claims. He rejected its preemption claims on the merits[1][3]. Those are two different kinds of loss, and they matter for what happens next.
What a Detainer Is, and Why Standing Failed
A detainer is a request from ICE. It asks a jail to hold someone for up to 48 hours after they would otherwise go free. ICE uses that time to take custody. An ICE officer signs it, not a judge[12].
The administration values detainers for a practical reason. A handoff inside a jail is safer and cheaper than finding someone on the street[12]. Cities see it differently. Holding someone past their release date is a new arrest. Reyes found that New York state law doesn't allow that arrest[1][3].
That finding drove the standing ruling. Standing means a plaintiff must show that a court's decision would actually change something for it. Here, state law already bars the detentions. So striking down the city's ban would change nothing for the government[3]. Reyes didn't need to say the city was right. He said the government wasn't the right party to win on that point.
The Information Fight
The second part of the ruling was decided on the merits. The city limits what it tells ICE about release dates and other custody details. The government said two federal laws, 8 U.S.C. 1373 and 1644, override those limits[1][3].
Reyes disagreed. He held that federal law doesn't require local governments to share that information. He also found that the two laws violate the Tenth Amendment[1][3]. He called the government's argument "nothing more than a backdoor around the Tenth Amendment"[4].
The key idea is the anti-commandeering doctrine. The Supreme Court has held that Congress can't order state or local officials to carry out federal programs. Murphy v. NCAA (2018) extended that to laws that forbid states from acting[16]. Washington can still enforce immigration law with its own agents. It can't make city workers do the job[16].
The government's reply is that Section 1373 asks for very little. It doesn't force police to arrest anyone. It only bars cities from forbidding employees to share information. The Second Circuit accepted that argument in 1999, when it rejected New York City's challenge to Section 1373[15]. Later district courts, including Reyes, have read Murphy as undercutting that view[3][15].
Two Sides, Both Making Constitutional Arguments
The administration's case starts with a basic point. Immigration is a federal power. Under the Supremacy Clause, valid federal law beats conflicting local law, and cities can't pass rules meant to get in its way[5][6]. Attorney General Pam Bondi, announcing the suit, said the city had "released thousands of criminals"[5].
DHS points to specific cases. It says Oscar Belgal was arrested by the NYPD in December 2023 and released under sanctuary policies[12]. An ICE officer shot Belgal in Marble Hill on Oct. 8, a week before the ruling. When a jail won't hand someone over, DHS says, agents must make arrests in the community[12][13]. The administration also wants a test case it can take to an appeals court or the Supreme Court[1]. Rep. Nicole Malliotakis of Staten Island, a Republican, praised the suit for holding the city "accountable" for its "dangerous" policies[19].
The city's argument is that the Constitution lets Washington enforce its own laws but doesn't let it draft city jailers and police to do that work[3][4]. City laws on this subject have stood across several administrations. Mayor Zohran Mamdani called the ruling "a victory for New Yorkers and a rebuke to ICE's deportation agenda"[8]. That second phrase goes further than the court's legal holding.
Immigrant advocates add that local limits keep a routine brush with police from turning into deportation. They point to the Belgal shooting as a sign that ICE's street operations carry their own dangers[13]. A federal judge has blocked Belgal's deportation while his case continues[13].
A Pattern of Losses
This isn't the government's first defeat. Federal judges have dismissed similar Justice Department suits against Illinois and Los Angeles, among other places[9][10]. The list also includes Minnesota, Colorado, New Jersey, New York state and Boston[4][11]. The reported searches turned up no sanctuary suit the department has won, in at least ten places[4].
The pressure underneath is simple. Without local help, ICE needs more agents and more arrests in the community. That drives both the lawsuits and the street operations[12][13]. Each court loss pushes the administration toward its own officers, funding pressure and appeals. It also feeds the political fight over Democratic-run cities[4][12].
For now, New York's jails and police can keep refusing detainers and withholding release-date information[4]. ICE can still make arrests in the city with its own officers[13].
How the Coverage Split
Outlets framed the same ruling differently. Reuters walked through the holdings claim by claim. It still described the policies as aiming "to shield immigrants from Trump's mass deportation campaign," which is how supporters describe them[1]. Gothamist led with the lack of standing and quoted the mayor. The government's public-safety case got little space there[2].
On the right, The Washington Times used the doctrine's own term in its headline, "can't commandeer locals." It also noted high up that Reyes was appointed by President Biden[4]. The Right Scoop headlined it as Trump personally having "LOST," with almost no attention to the legal reasoning[17]. Courthouse News also put the loss on Trump in its headline, though its body covers the holdings in detail[3].
The Eastern Herald, an online outlet with Indian roots, tied the ruling to the Belgal shooting. The court didn't address that shooting, and the two events are legally unrelated[14].
What Happens on Appeal
The Justice Department didn't immediately comment, and it's unclear whether it will appeal[2]. Any appeal would go to the Second Circuit. That court's 1999 decision upholding Section 1373 is the strongest precedent the government has[15].
So the live question is narrow. Will the Second Circuit stand by that ruling after Murphy v. NCAA[15][16]? The standing finding on detainers may be harder to overturn. The information-sharing ruling is the one most likely to get a second look.
Summary
On Thursday, Oct. 15, 2026, a federal judge in Brooklyn threw out the Trump administration's lawsuit against New York City's sanctuary laws[1][2]. These city laws limit how much the jails and police help U.S. Immigration and Customs Enforcement (ICE). The Justice Department filed the suit in July 2025, when Eric Adams was mayor[1][5]. It argued that the laws block federal immigration enforcement and are overridden by federal law[5][6].
U.S. District Judge Ramón Reyes Jr. ruled in two parts. First, he said the government had no standing to challenge the city's ban on holding people for ICE. New York state law already forbids that, so striking down the city law would change nothing[1][3]. Second, he upheld the city's limits on sharing release dates and other custody details. He found that the federal laws the government relied on cannot force local governments to help[1][3]. He called the government's argument "nothing more than a backdoor around the Tenth Amendment"[4].
Mayor Zohran Mamdani called the ruling "a victory for New Yorkers"[8]. The Justice Department did not immediately comment, and it was not clear whether it would appeal[2]. The government has now lost similar suits against Illinois, Minnesota, Colorado, New Jersey, New York state, Los Angeles, Boston and other places[4][9][10][11].
The core dispute is over who controls local jail workers and the data they hold. The administration says that when cities refuse to hand people over in jail, ICE must arrest them on the street, which is more dangerous[12]. The city and the courts that ruled against the government say the Constitution leaves those choices to local officials[3][4]. Any appeal would go to the Second Circuit. That court upheld one of the same federal laws against a New York City challenge in 1999[15].
The Event
On Oct. 15, 2026, U.S. District Judge Ramón Reyes Jr. of the Eastern District of New York dismissed United States v. City of New York[1][2]. The suit was filed in Brooklyn federal court on July 24, 2025. It challenged city laws, including a 2011 provision, that bar the Department of Correction from honoring ICE detainers, along with NYPD rules that limit cooperation with immigration agents[5][6]. Reyes found the government lacked standing on the detainer claims and rejected its preemption claims on the merits[1][3].
Undisputed Facts
- The Justice Department sued New York City and then-Mayor Eric Adams over the city's sanctuary laws on July 24, 2025, in Brooklyn federal court[5][6].
- Judge Ramón Reyes Jr., appointed by President Biden, dismissed the lawsuit on Oct. 15, 2026[1][4].
- Reyes found the government lacked standing to challenge the city's ban on holding people for ICE because New York state law separately bars the practice[1][3].
- Reyes ruled that federal law does not require local governments to share release dates or custody information. He also found that 8 U.S.C. 1373 and 1644 violate the Tenth Amendment's anti-commandeering doctrine[1][3].
- Federal judges have earlier dismissed Justice Department suits over sanctuary policies in Illinois and Los Angeles, among other places[9][10].
- In 1999, the Second Circuit rejected New York City's anti-commandeering challenge to Section 1373 in City of New York v. United States[15].
- An ICE officer shot Oscar Belgal in Marble Hill on Oct. 8, a week before the ruling. DHS said the NYPD had arrested Belgal in December 2023 and released him under sanctuary policies; the court did not address the shooting[12][13].
The Pressure
Strip away the moralizing and blame. What structural realities persist regardless of which narrative wins?
- Anti-commandeering doctrine
- The Supreme Court has held that Congress cannot order state or local officials to carry out federal programs. Murphy v. NCAA (2018) extended this to laws that forbid states from acting[16]. Here is why it matters. The federal government can still enforce immigration law with its own agents. But it cannot make city workers do the work or tell city councils how to direct them. The government's reply is that Section 1373 only stops cities from banning information sharing, and that this is too small to count as commandeering. The Second Circuit agreed in 1999. Later district courts, including Reyes, have read Murphy as undercutting that view[3][15].
- How a detainer works
- A detainer is a request from ICE asking a jail to hold someone for up to 48 hours after they would otherwise go free. ICE uses that time to take custody. An ICE officer signs it, not a judge. The administration values detainers because a handoff inside a jail is safer and cheaper than finding someone on the street[12]. Cities resist because keeping someone past their release date is a new arrest. Reyes found New York state law does not allow that arrest[1][3]. That is why he said the government lacked standing: winning against the city would not change the state-law bar[3].
- Federal enforcement capacity
- Without local help, ICE needs more agents and more arrests in the community. This drives both the lawsuits and the street operations, such as the one in which Belgal was shot[12][13].
Material realityNew York City's jails will keep refusing ICE detainers and withholding release-date information unless a higher court reverses this ruling[1][4]. The Justice Department has now lost every sanctuary suit reported in these searches, in at least ten places[4]. The live legal question is whether the Second Circuit stands by its 1999 Section 1373 ruling after Murphy v. NCAA[15][16]. Whatever the courts decide, ICE can still make arrests in New York with its own officers[13].
Narrative as a weaponThe administration and DHS want readers to see sanctuary laws as releasing dangerous people, and they point to individual cases like Belgal's[12]. The Mamdani administration wants the ruling read as a rebuke to ICE itself, which goes beyond the court's legal holding[8]. Partisan aggregators on the right present the case as a personal defeat for Trump and highlight the judge's appointing president[4][17]. Some outlets tie the ruling to the Belgal shooting, which the court did not address[14]. Note that the standing finding applied to the detainer claims, while the information-sharing claims were decided on the merits[1][3].
How Each Side Sees It
Each major actor’s view — how it frames things, its underlying incentive, and how it’s materially affected. Tap a side to read it.
Frames it asImmigration is a federal power. Under the Supremacy Clause, cities cannot pass laws meant to get in its way[5][6]. When a jail releases someone ICE has asked to hold, agents must find that person later in the community. DHS says the Belgal shooting began with exactly that kind of release in 2023[12]. The government also argues that Section 1373 asks for very little. It does not force police to arrest anyone. It only bars cities from forbidding employees to share information. The Second Circuit upheld it on those grounds in 1999[15].
WhyTo make it easier to carry out mass deportations by getting people from local jails rather than through street arrests. The administration also wants a test case it can take to an appeals court or the Supreme Court[1].
Impact on themThe administration keeps losing these cases around the country[4], which weakens the legal path. Now it must rely on its own agents and on pressure such as funding threats. These losses also fuel its political attacks on Democratic-run cities[12].
Frames it asThe Constitution lets Washington enforce its own laws. It does not let Washington draft city jailers and police to do that work[3][4]. Holding someone after their release date, on an ICE request that no judge signed, is a new arrest. State law does not allow it[1][3]. Mamdani called the ruling "a victory for New Yorkers and a rebuke to ICE's deportation agenda"[8].
WhyTo protect city laws that have stood across several administrations. The city also wants to avoid legal liability for unlawful detentions and to keep immigrant communities willing to deal with city police and agencies.
Impact on themFor now, the city's jails and police can keep refusing ICE detainers and data requests[4]. The city still faces political and funding pressure from Washington and a possible appeal[1].
Frames it asSanctuary laws protect people who are already in the criminal system. Rep. Nicole Malliotakis of Staten Island praised the 2025 suit for holding the city "accountable" for its "dangerous" policies[19]. Critics see a judge appointed by Biden as part of a pattern of courts blocking enforcement[4][17].
WhyTo keep public safety and immigration at the center of the political debate, and to push Congress or higher courts to act[19].
Impact on themDefeats in court shift the fight toward legislation, funding conditions and appeals[4].
Frames it asLocal limits keep a routine contact with police or jail from turning into deportation. Advocates point to the Belgal shooting as a sign that ICE operations themselves cause danger. A federal judge has blocked Belgal's deportation while his case continues[13][14].
WhyTo keep local agencies out of federal deportation work[2].
Impact on themPeople held in city jails will not be transferred to ICE through detainers. ICE operations in the community continue[13].
