On August 10, 2026, a Staten Island judge stopped Mayor Zohran Mamdani (D) cold on the marquee tax of his first year in office — ruling that the city broke its own notice laws while trying to collect it. State Supreme Court Justice Wayne Ozzi issued a temporary restraining order requiring New York City to take down the searchable database of roughly 960,000 property owners the Department of Finance had published, and barring the city from acting further on the 17,000 notices it had already mailed warning recipients they could owe a five-figure tax bill.
This is a new legal development, not a rehash of the database controversy this publication covered in late July. That story was about what the city published. This one is about a judge ruling, in writing, that the city was not legally allowed to publish it — and that its entire process for collecting the tax put the burden of proof on the wrong side.
The win for homeowners came with an asterisk almost immediately: within hours, City Hall’s Law Department filed to appeal, a move that under New York court procedure automatically paused Ozzi’s order. The rollout, and the fight over it, both continue.
The case is O’Brien v. City of New York, Index No. 85217/2026, filed in State Supreme Court, Richmond County. In his Monday ruling, Justice Ozzi found that the city’s notice letters did not satisfy state tax law and unlawfully shifted the burden onto property owners to prove they should not be taxed, rather than requiring the Department of Finance to make an “individualized statutorily-required initial determination” before flagging anyone at all. The order does two concrete things: it directs the Department of Finance to take the published property roll off its website, and it bars the city from imposing, assessing, or collecting the surcharge — or sending any further notice — against anyone on that list until it follows the process the law actually requires.
“No law permitted or required the City to publish such a list of the names, addresses, and property values of more than 900,000 New York City homeowners.”

Attorney Randy Mastro, representing the three homeowners who sued, put it more bluntly in court: “The city screwed this up…got it wrong…stop the train and make them do it over.” After the ruling, he added: “We are very gratified by the judge’s decision, which has vindicated the rights of hundreds of thousands of New York City homeowners who were subjected to a process they never should have been a part of in the first place.”
The pied-à-terre surcharge was enacted as part of New York State’s FY2027 budget in late May 2026 and took effect July 1. It layers an annual surcharge onto non-primary homes: 0.8% to 1.3% on one-, two-, and three-family houses worth $5 million or more, and 4% to 6.5% on condos and co-ops worth $1 million or more. The administration projects it will raise $500,000,000 a year; NYC Comptroller Mark Levine (D) has separately estimated a more realistic $340 million–$380 million. On July 27, the Department of Finance published the searchable database at the center of this fight — roughly 960,000 property records, all names and addresses attached — about 30 times the roughly 31,000 homes the Department of Finance itself expects will actually owe the tax.
The lawsuit is not the simple story either side might want it to be. Two of the three plaintiffs, Rachel O’Brien and Carmine Morano, are the wife and father of Republican City Council Member Frank Morano (R-Staten Island). The third, Simon Hedley, is a Chelsea homeowner of 13 years who says he supports Mamdani and backs taxing the rich — and who still received a notice in July, filed for an exemption that Saturday, and was told Monday morning, hours before the ruling, that he was in fact exempt. He stayed in the suit anyway. The complaint does not challenge the tax itself; it challenges the sequence the city used to collect it.
Mastro is a familiar Mamdani antagonist — he resigned as First Deputy Mayor under Eric Adams in 2025 and has since represented plaintiffs in several suits against the current administration. Morano, whose Staten Island district includes his own family among the plaintiffs, framed his objection narrowly at the time the suit was filed: “My concern isn’t that people have to prove where they live. My concern is the sequence. The city should verify first.” Staten Island Borough President Vito Fossella (R) welcomed the ruling in stronger terms, calling the rollout “one of the most mishandled, inappropriate rollouts of a policy that we have ever seen” and saying the city “committed an injustice against the hardworking homeowners who make up its foundation” — adding that the court’s intervention “should be a stark message to this City that enough is enough.”
Publishing this list of properties was ridiculous. It really looks like they just put together every 1- and 2-family home and condo and said they 'could' be subject to the pied-a-terre tax. None of the properties including my neighbors and I make the financial threshold for the tax.
Mamdani did not back down at his Monday press conference, opening with a jab at his opponent’s attorney: “There are few things more certain in New York City than death, taxes and Randy Mastro filing a lawsuit against this administration.” He pledged the city would “vigorously defend” its position. Mayoral spokesman Matt Rauschenbach was more measured in the city’s official statement: “We disagree with today’s ruling, but we are confident in both the pied-à-terre surcharge and the City’s ability to implement it fairly and effectively.” The Law Department said it would appeal “immediately” — and it did, within hours.
Here is the wrinkle most headlines skipped: filing that appeal automatically stayed Justice Ozzi’s order under New York’s civil procedure rules, meaning the city was not actually required to take the list down or freeze the rollout the moment the ruling landed. The judicial rebuke is real and on the record. Its practical effect, pending the August 31 hearing, is contested — the city says it intends to keep moving forward in the meantime, and roughly 2,000 homeowners had already filed exemption paperwork before the ruling even came down.
One detail cuts against any narrative that this was a partisan judge settling a score: Justice Ozzi was first appointed to the Court of Claims by Gov. David Paterson (D) in 2010 and reappointed by Gov. Andrew Cuomo (D) in 2017; he is registered as a Democrat, per Washington Examiner reporting. A Democrat-appointed jurist found that a Democratic administration’s own tax agency broke the state’s notice-and-process rules — a fact worth sitting with before assuming this ruling was ideological.
President Donald Trump (R) has been a running critic of the tax since it was announced, warning New Yorkers on Truth Social that the city was on the wrong track months before any court got involved.
If Communist Candidate Zohran Mamdani wins the Election for Mayor of New York City, it is highly unlikely that I will be contributing Federal Funds, other than the very minimum as required, to my beloved first home.
Sadly, Mayor Mamdani is DESTROYING New York! It has no chance! The United States of America should not contribute to its failure. It will only get WORSE. The TAX, TAX, TAX Policies are SO WRONG. People are fleeing. They must change their ways, AND FAST.
A judge has temporarily blocked Mayor Zohran Mamdani's pied-à-terre tax, according to FOX 5 NY's political reporter Morgan McKay.
The stakes for City Hall are straightforward: the pied-à-terre tax is doing real work inside Mamdani’s budget, and the administration’s own $500,000,000 projection was already $120 million to $160 million above the Comptroller’s realistic estimate before a judge found the collection process itself unlawful. The August 31 hearing on the merits — not this week’s temporary order — will decide whether the city has to rebuild the rollout from scratch or can keep the list live and the notices moving while it appeals.
A Staten Island judge — a Democrat, appointed twice by Democratic governors — ruled that Mayor Zohran Mamdani’s (D) administration broke state notice law in rolling out its pied-à-terre tax, ordering the city to take down a list of roughly 960,000 homeowners and stop acting on 17,000 mailed notices. The city appealed within hours, automatically staying the order, and says it will keep pressing forward. The three plaintiffs aren’t a clean partisan cast either: two are family of a Republican councilman, the third is a self-described Mamdani supporter who got exempted the same morning the ruling came down. Nobody is challenging the tax itself — only whether the city followed its own rules to collect it. That question goes back to court August 31, with roughly $500 million a year in projected revenue riding on the answer.
