New York City can keep rolling out its pied-à-terre tax on higher-value second homes after an appellate judge allowed implementation to proceed during a legal fight. The decision followed a temporary restraining order issued Monday by Staten Island Judge Wayne Ozzi, but the city's appeal triggered an automatic stay that kept the surcharge alive for now. The dispute does not challenge the tax itself. Instead, three city residents are contesting the legality of the rollout, focusing on the city's release of information covering thousands of homeowners and notices sent to 17,000 people who may fall under the levy. The tax is a signature policy of New York City Mayor Zohran Mamdani and has become a flashpoint in a broader political debate, drawing criticism from conservatives and wealthy residents. President Donald Trump, who moved his primary residence to Florida in 2019, said the tax "must be stopped, NOW!" and said he was examining whether the federal government had any legal way to intervene.
