In a significant legal setback for Mayor Mamdani, a New York City judge has ordered a complete redo of the controversial pied-à-terre tax rollout, deeming it flawed and improperly executed. This ruling mandates the city to scrap over 17,000 tax notices related to the second-home tax and begin the process anew. The decision comes amidst widespread opposition, including challenges from property owners who argue that the tax is unconstitutional. Notably, casino mogul Steve Wynn and former Trump administration official Wilbur Ross have joined forces to contest the tax, amplifying the legal challenges facing the Mamdani administration. As the city appeals the ruling, it faces mounting pressures and public scrutiny over its luxury property tax initiatives.
