The city's pilot program to allow riders to hail yellow taxis with a smartphone app was halted once again in New York State Supreme Court on Wednesday.
The experimental service officially debuted on Tuesday and was supposed to have be offered for a year.
City officials say the program gives riders more choices, but opponents of the app, including livery car owners, say it breaks a law that prohibits drivers from refusing passengers without grounds.
The City Law Department says it is disappointed by the appellate ruling and Taxi and Limousine Commissioner says in a statement, "It is appalling that narrow commercial interests continue to try to block passengers from using the latest technology. You can't stop progress, and these obstructionists shouldn't be trying. We're confident this program will move forward."
