Judge voids Mamdani second-home tax notices and forces a full restart

A Staten Island judge ordered New York City Mayor Zohran Mamdani’s administration to cancel roughly 17,000 pied-à-terre tax notices and start the rollout over after finding the city failed basic legal procedures.

Justice Wayne Ozzi ruled the notices were arbitrary and capricious, tainted by errors of law, and violated recipients’ due process rights. The decision struck at one of the mayor’s signature revenue plans almost a year into his term.

Fox News reported that City Hall filed an appeal within hours, triggering an automatic stay of the lower-court order. An unnamed city official said the stay lets the city keep moving on the surcharge while the fight continues.

The court fight is not a side skirmish. It goes to how City Hall treats property owners, public records, and the law when it wants money fast.

What the judge actually found

Ozzi did not ban the surcharge forever. He found the city skipped required steps before mailing the notices and then shifted the burden onto homeowners to prove they should be exempt.

The New York Post reported that more than 1,000 people who received notices were not even subject to the tax. Homeowners who got the wrong letters were “substantially harmed and penalized needlessly,” Ozzi wrote, because they had to prove to city officials that they should not owe the new charge.

The judge’s path forward was blunt. The city had to pull the current list of taxed properties from its website, post a corrected list only after following proper procedures, and mail new notices that comply with the law.

Attorney Randy Mastro, representing challengers, put the failure in plain terms in court coverage by Just the News.

“The city screwed this up… got it wrong… stop the train and make them do it over. The city is to bear the burden. They didn’t do their homework.”

That is the core of the ruling: process first, revenue second. City Hall tried to reverse the order.

How the tax was sold, and who it hit

Mamdani announced the pied-à-terre surcharge in April as a fairness measure aimed at luxury second homes. In a press release at the time, he cast it as budget repair with Governor Hochul’s support.

Mamdani said then:

“Thanks to the support of Governor Hochul, we are one step closer to balancing our budget by taxing the ultra-wealthy and global elites with a pied-à-terre tax, the first of its kind in our state. Alongside the governor, our administration is fighting every day to make sure we address this fiscal deficit fairly, where the wealthy contribute what they owe and our budget reflects our commitment to the working New Yorkers being priced out of our city.”

In its original form, the surcharge targeted one-to-three family homes, condominiums, and co-ops valued above $5 million when the owner also held additional property outside New York City. Later reporting described the broader framework as covering high-value unoccupied non-primary residences, including co-ops and condos at lower valuation floors in some accounts, with projected yearly revenue near $500 million.

Spokesperson Matt Rauschenbach defended the policy as a “basic principle of fairness” after the setback and framed opponents as protecting privilege.

“If you can afford a luxury second home in New York City, you can afford to pay your fair share for the schools, streets and parks that make this city work.”

He added that the administration would not retreat.

“Our administration is fighting every day to deliver for working New Yorkers. The ultra-wealthy are fighting in court to avoid paying their fair share. They have filed lawsuit after lawsuit to protect their privilege, and we will not back down.”

After Ozzi’s decision, Rauschenbach said the ruling was wrong and that the city would invoke a stay to keep implementing the surcharge “fairly, efficiently and in full compliance with the law, as we have since day one.” The court record on the notices told a different story about compliance.

Readers following Mamdani’s other legal fights will recognize the pattern of City Hall testing limits and then litigating the fallout, including when Mamdani sued to block a teachers union pay-raise plan in a separate clash with labor.

The public list and the early freeze

Before the full cancel-and-restart order, homeowners had already won temporary relief. Breitbart reported that Ozzi issued a temporary restraining order stopping enforcement, requiring the Department of Finance to take down a list covering roughly 960,000 properties, and pausing action on notices sent to about 17,000 owners, with a hearing set for Aug. 31.

Plaintiffs named in that challenge included homeowners Rachel O’Brien, Carmine Morano, and Simon Hedley, who sued in Richmond County Supreme Court. The list problem was not a technical footnote. Publishing names, addresses, and values of hundreds of thousands of owners turned a tax rollout into a privacy and due-process fight overnight.

The Washington Examiner described the emergency order as blocking imposition and collection of the surcharge and barring further action on the letters until the city made the individualized determinations state tax law requires. The lawsuit alleged wrong primary-residence calls, skipped individualized reviews, and improper burden-shifting onto owners.

Mastro welcomed the earlier win in language that matched the later cancel order: the process itself had dragged in people who never should have been on the list. Rauschenbach answered that the city disagreed with the ruling but remained “confident in both the pied-à-terre surcharge and the City’s ability to implement it fairly and effectively.”

That confidence has now met a second judicial rebuke on the same implementation track. An appeals court fight over the pied-à-terre tax already sits in the background of this policy’s long court path.

Appeal, automatic stay, and what City Hall claims now

Hours after Ozzi canceled the mailed notices, the Mamdani administration appealed. Under the automatic stay, a city official said implementation can continue while the lower-court order is paused.

The official’s line was direct:

“The auto stay allows the city to continue, as we have been, with the implementation of the pied-a-terre surcharge and puts the lower court’s order on pause.”

That claim sits beside the judge’s finding that the first wave of notices failed due process. Continuing under a stay does not erase the procedural defects Ozzi listed. It buys time.

The New York Post framed the cancel-and-restart ruling as a major setback for a policy meant to raise more than $500 million a year, and noted additional constitutional challenges from figures including casino mogul Steve Wynn and Wilbur Ross. Those suits go beyond mailing errors to the tax’s legal foundation.

Mastro’s reaction after the cancel order tracked the same theme as the TRO stage: state law put the burden on the city, not on owners to prove they live in their own homes.

City Hall’s political message has not changed. Mamdani has cast the surcharge as money “working New Yorkers, and this city, deserve.” Council pushback has been sharper. Councilwoman Inna Vernikov called the approach “Marxism in practice,” arguing the mayor keeps promising middle-class relief by punishing the wealthy. That clash is policy and incentives, not courtroom procedure, and it is the argument voters will hear while lawyers sort the notices.

Mamdani’s broader tenure has kept him in contested public fights well beyond tax court, from Italian-American leaders objecting to parade invitations to repeated scrutiny of his public appearances.

Other legal fronts around the same mayor

The pied-à-terre case is not isolated. Reporting around the same period noted legal pushback on a rent freeze plan, a state-sponsored grocery store concept challenged by the National Supermarket Association over unfair competition claims, and specialized high school admissions disputes. Each file is separate. Together they show an administration writing big rules first and defending the paperwork later.

Ozzi left the policy door open if the city follows the statute. Remove the flawed list. Build a corrected one. Make individualized determinations. Mail clean notices. That is not a veto of “tax the rich” rhetoric. It is a demand that City Hall obey the same process rules it imposes on everyone else.

For owners who got false notices, the harm was immediate: a public list, a demand letter, and the job of proving a negative to the agency that made the mistake. For taxpayers watching the budget pitch, the revenue number only matters if the city can administer the tax lawfully. Right now the record shows a rushed list, thousands of contested letters, and a judge ordering a do-over.

Public controversy around the mayor has not been limited to finance either. Families and mourners have pressed hard over Ground Zero optics, including a petition drive aimed at blocking his role at the 25th anniversary ceremony, a reminder that process and public trust travel together.

What still has to be answered

Open questions remain on the docket path and the next mailing wave. The absolute calendar dates for each filing step are still sorted in court papers. The full case caption and the complete list of statutory steps the city missed are for the appellate record to spell out. How many of the roughly 17,000 notices were pure error, and how fast Finance can build lawful individualized files, will decide whether the surcharge becomes real money or another stalled headline.

What is already clear is simpler. A judge found the first rollout arbitrary, legally flawed, and unfair to recipients. The mayor’s team answered with an appeal and a stay. Homeowners answered with more suits. The policy may survive. The first notices did not.

When city government treats due process as optional paperwork, working owners pay first, in time, in risk, and in trust, long before any “fair share” check clears.
