The administration of New York City Mayor Zohran Mamdani has officially challenged a recent court ruling issued by a Staten Island judge. The underlying legal dispute concerns the city’s 'pied-à-terre' tax, a levy targeting secondary residences. The judge had previously issued an order prohibiting the city from sending out tax notices to affected property owners.

Following the filing of the appeal on Tuesday, a city official confirmed that the administration is invoking the 'auto stay' provision under New York state law. This legal mechanism is intended to pause the effect of a lower court's ruling while the appeals process unfolds. By invoking this stay, the city asserts that it is legally permitted to continue its administrative efforts regarding the tax, despite the initial injunction. The move signals a significant escalation in the city's attempt to enforce the tax policy, which has faced pushback from property owners and legal challenges in the Staten Island courts. The litigation remains ongoing as the city seeks to overturn the judge's original decision to block the notification process.
