A New York City judge voided Mayor Zohran Mamdani’s second-home tax notices for skipping required procedures, and City Hall appealed within hours to keep the surcharge moving.
Judge Wayne Ozzi ordered the city to cancel the pied-à-terre tax notices it had already mailed, finding the rollout failed basic legal steps. Fox News reported that Mamdani’s administration filed an appeal the same Tuesday, just hours later, triggering an automatic stay of the order.
That stay pauses the lower-court ruling for now. An unnamed city official said the city can keep implementing the surcharge while the fight continues. The core problem the judge identified does not disappear because City Hall moved fast.
Ozzi’s ruling did not ban the tax forever. It said the city botched the process used to hit property owners with notices. He left a path open: pull the current taxed-properties list off the website, post a corrected list after proper procedures, and mail new notices that follow the law.
The judge’s language was blunt. He found the notice process “arbitrary and capricious, affected by errors of law, and in violation of the recipients’ due process rights.”
Due process is not a loophole for the rich. It is the requirement that government follow fair steps before it bills people, seizes leverage, or puts names on a public hit list of taxed properties.
Mamdani’s team answered with speed, not humility. Spokesperson Matt Rauschenbach said the decision was wrong and that the city would invoke a stay.
Rauschenbach said:
"Today’s decision is wrong, and we will invoke a stay of the injunction. With a stay, we will continue implementing the surcharge fairly, efficiently and in full compliance with the law, as we have since day one."
A city official put the practical effect in plain terms: the auto stay lets the city continue “as we have been” with the pied-à-terre surcharge and puts the lower court’s order on pause.
So the notices were struck for breaking procedure, and the administration’s first move was to keep rolling under a stay. That is the pattern: process later, political tax first.
Mamdani announced the second-home tax in April. In its original form, it was an annual surcharge on one-to-three-family homes, condominiums, and co-ops valued above $5 million. The design applied to owners who also held additional property outside New York City.
He framed it as budget math aimed at the “ultra-wealthy and global elites.” In a press release at the time of the April announcement, Mamdani said:
"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."
After Tuesday’s ruling, his spokesman kept the same theme. Rauschenbach cast the surcharge as a “basic principle of fairness” and said the city should not be a “tax haven for the wealthy few.”
He also said:
"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."
And he went further, blaming opponents rather than the city’s own procedural failure:
"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."
The judge did not rule that second-home owners are above the law. He ruled that the city failed required procedures before it mailed the notices. Those are not the same claim, no matter how often City Hall merges them.
The pied-à-terre fight is not arriving in isolation. Reporting on the same dispute notes other legal pushback tied to Mamdani’s agenda, including a rent freeze plan, a state-sponsored grocery store plan challenged by the National Supermarket Association over unfair competition concerns, and specialized high school admissions fights involving parents.
Mamdani is approaching nearly a year since voters elected him mayor. In that short span, major pieces of his program are already meeting courts, trade groups, and organized opponents, not only campaign rhetoric.
On the tax itself, the judge’s roadmap was clear enough. The policy can still be attempted if the city removes the current list of taxed properties from its website, posts a corrected list after following proper procedures, and mails new notices in compliance with the law. The administration chose an appeal and an automatic stay instead of treating the order as a stop-and-fix moment.
That choice matters. When officials sell a levy as moral necessity, they still have to obey the same notice and process rules everyone else lives under. Labeling targets “global elites” does not shrink those duties.
Homeowners who got the canceled notices now sit in limbo while the stay holds and the appeal proceeds. The city says implementation continues. The judge said the first mailing wave violated due process. Both statements can be true at once, and that is the mess City Hall created by rushing the rollout.
Taxing property is a power of government. Skipping required procedures is a choice. Mamdani’s team can call it fairness all day; a judge already called the notice process unlawful, and an appeal does not rewrite that record.
