Transport Workers Union Local 100 has threatened to seek an immediate court order if New York City Council approves a bill to end horse carriage rides in Central Park.

Union attorney Arthur Schwartz made the threat in an Oct. 21 letter to city Corporation Counsel Steve Banks. The bill was due for a Health Committee vote before reaching the full council. The union, carriage workers and owners say the proposal does not do enough to protect workers.

City Council Speaker Julie Menin unveiled an amended version last week that would phase out the Central Park carriage industry by June 2028. The mayor supports the measure, known as Romanch’s Law. It gained momentum after Romanch Mahajan, an 18-year-old tourist from India, died after being thrown from a carriage. The bill has not yet passed.
