A New York City judge canceled Mayor Zohran Mamdani’s mailed second-home tax notices over legal and due process failures, and City Hall immediately appealed to keep the surcharge moving anyway.
Hours after the ruling on Tuesday, the Mamdani administration filed an appeal that triggered an automatic stay, pausing the lower court’s order while the city presses ahead with its pied-à-terre surcharge.
Fox News reported that Judge Wayne Ozzi found the city failed to follow required procedures before mailing the notices and ordered those notices canceled. Ozzi described them as “arbitrary and capricious, affected by errors of law, and in violation of the recipients’ due process rights.”
That is the core of the fight. City Hall framed the tax as fairness for working New Yorkers. A judge said the rollout trampled basic process protections for the people hit with the notices.
Ozzi did not kill the policy outright. He said the city can still apply the surcharge if it removes the current list of taxed properties from its website, posts a corrected list after proper procedures, and mails new notices that comply with the law.
In plain terms, the judge told City Hall to start over on notice and process. The administration chose a faster path: appeal, lock in the automatic stay, and keep implementing.
A city official put it directly: “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.”
Mayoral spokesperson Matt Rauschenbach went further. “Today’s decision is wrong, and we will invoke a stay of the injunction,” he said. “With a stay, we will continue implementing the surcharge fairly, efficiently and in full compliance with the law, as we have since day one.”
Those two claims now sit side by side. The court said the notices violated due process. City Hall said it has been compliant since day one and will keep going under the stay.
Mamdani announced the second-home tax back in April. In that press release, he tied the idea to budget math and class politics.
“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.”
As designed, the surcharge targets one-to-three family homes, condominiums, and co-ops valued above $5 million. It applies to owners who also hold additional property outside New York City.
Rauschenbach defended the tax in the same fairness language after the ruling. “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 said.
He also cast opponents as protectors of privilege: “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 court fight is not about whether luxury second homes exist. It is about whether City Hall mailed enforceable notices under lawful process. Ozzi’s answer was no.
Progressive tax pitches often arrive wrapped in moral certainty. This one came with a judicial finding that the notices were arbitrary, legally flawed, and hostile to due process.
Due process is not a loophole for the rich. It is the rule that government must follow before it hits people with new burdens. When a city skips required steps, the target class does not erase the violation.
Ozzi’s remedy was straightforward. Cancel the bad notices. Take down the flawed list. Rebuild the list under proper procedures. Mail clean notices. Then apply the tax.
City Hall’s response was just as clear. Call the decision wrong. Invoke the stay. Keep implementing while the appeal runs.
That sequence tells taxpayers what the administration values first: speed and revenue posture, not a clean administrative record.
The pied-à-terre fight is not arriving in isolation. Reporting on the case also notes other legal pushback around Mamdani’s agenda, including challenges tied to a rent freeze plan, a state-sponsored grocery store plan opposed by the National Supermarket Association over unfair competition concerns, and specialized high school admissions disputes.
None of those side fights replaces the tax ruling. They do show a pattern of aggressive policy launches colliding with courts, industry groups, and process rules early in the mayoral tenure, now approaching a year since his election.
A policy can be popular with activists and still fail basic government standards. Mailing notices the court calls arbitrary and unlawful is one of those failures.
If the surcharge is lawful and necessary, City Hall can prove it the ordinary way: follow the procedures, publish an accurate list, and send notices that survive judicial review. The stay lets officials avoid that reset for now. It does not erase the finding that forced the reset in the first place.
Working New Yorkers do not gain from a city that lectures about fairness while shortcutting the rules that protect every property owner from careless government power.
