The city got the green light to test out a program that would let people hail yellow cabs with their smartphones.
A Manhattan judge on Tuesday dismissed a lawsuit that sought to put the brakes on the "e-hail" program.
Livery cab owners claimed it would violate a law that prohibits drivers from refusing passengers without grounds.
The judge says the e-hail plan might actually prevent discrimination, because it would make drivers accept passengers before seeing what they look like.
Taxi and Limousine Commissioner David Yassky says the decision is a victory for riders.
TLC officials have agreed to try out the system for a year.
There is no word yet on when the pilot program would start.
