Mamdani's nemesis sued to block the city's pied-à-terre tax. The city froze the judge's pause

Key Points:

• Randy Mastro filed a lawsuit on behalf of three homeowners challenging New York City's Department of Finance (DOF) over the flawed rollout of the pied-à-terre tax, arguing the city improperly shifted the burden onto homeowners to prove exemption rather than conducting proper upfront assessments.
• Staten Island Supreme Court Judge Wayne Ozzi temporarily ruled in favor of Mastro, ordering the city to remove the online database of properties and halting tax enforcement, but the city immediately filed an intention to appeal, which automatically stayed the ruling and allowed the tax rollout to continue.
• Critics, including real estate attorney Stuart Saft, argue the underlying statute is poorly written and the DOF's rushed and flawed implementation exacerbated problems, with assessment methods disadvantaging co-op and condo owners compared to single-family homes.
• Mayor Zohran Mamdani and city officials defended the tax as a necessary surcharge on secondary homes valued over $5 million to fund city services, while Governor Kathy Hochul stated the law remains intact despite the lawsuit affecting only the rollout.
• The legal battle continues with oral arguments scheduled for August 31, leaving homeowners in uncertainty as enforcement is paused temporarily but the tax itself remains valid pending resolution.
