Appeals Court Revives Mamdani Second Home Tax Plan

New York City's plan to tax high-end second homes has cleared a major legal obstacle after an appeals court overturned a lower court ruling on Wednesday, allowing Mayor Zohran Mamdani's administration to continue implementing the measure. The decision, issued by an appellate panel in Brooklyn, marks a significant legal victory for the mayor's economic agenda.

The ruling reverses a September decision by a Staten Island judge who found that the city had mishandled the tax's rollout and ordered officials to restart the process. The administration immediately appealed that decision and continued advancing the tax while the lawsuit remained pending.

However, the latest ruling does not resolve all legal disputes surrounding the measure. The tax continues to face separate challenges, particularly over its constitutionality.

Mamdani has promoted the proposed tax as a way to fulfill his campaign commitment to "tax the rich" and generate additional revenue to help address New York City's budget deficit.

The mayor welcomed the appellate court's decision in a statement released Wednesday, describing himself as "heartened" by the outcome.

"From Day 1, those with the most have attempted to use every legal avenue available to shield their wealth and avoid contributing more to our city," said Mayor Zohran Mamdani.

The ruling also comes as Mamdani's administration faces legal battles over other campaign priorities. His lawyers are defending several policies, including a proposed rent freeze for rent-stabilized apartments.

Homeowners challenging the second-home tax were represented by attorney Randy Mastro, who criticized the appeals court's decision. He did not disclose whether the plaintiffs intended to pursue another appeal.

Mastro described the city's implementation process as "lawless and chaotic" and argued that the alleged problems would "go unremedied."

The attorney also maintained that constitutional challenges to the tax itself would ultimately succeed. That argument is central to other lawsuits against the measure, including a separate case filed by Mastro.
