Prosecutors’ use of global positioning system data to track the movements of a New York City taxi driver accused of overcharging almost 300 passengers did not violate the driver’s Fourth Amendment right to privacy, a Manhattan judge has ruled.

Criminal Court Judge Diana M. Boyar rejected a suppression motion filed by Asif Suleman, ruling that he could not show a “reasonable expectation of privacy” in his cab because he knew that his performance was being measured with the GPS technology.
