A judge has nixed this month's rollout of the Taxi of Tomorrow.
The court ruled Tuesday that the city's new uniform model of environmentally sustainable taxis violated the Americans with Disabilities Act.
The Greater New York Taxi Association and a taxi medallion owner filed the suit, claiming that the mayor's plan would force them to buy a car they didn't want.
"This was similar to the problem of the soda ban," said Attorney Steven Mintz. "This was an administrative agency going well beyond the bounds of power for decisions that are supposed to be made by the elected body for the simple reason that if the public does not like the decisions of the elected body, the public can then vote out the elected body."
The Taxi of Tomorrow was supposed to be a new Nissan NV-200 model that officials say would work better for riders and drivers.
It was intended to slowly replace all taxis currently on city roads.
The Taxi and Limousine Commission called the judge's decision Tuesday "fundamentally wrong," and said it planned to appeal immediately.
