The temporary injunction on the service, which allows drivers to connect with potential passengers through a smartphone application, had been imposed by the court at the end of last month before a hearing could be held. Uber began its low-cost service, UberPop, in April, and Taxi Deutschland submitted its legal challenge in August, arguing that Uber did not provide the necessary licenses and insurance for its drivers. “Uber stands for a particularly extreme form of wage dumping, which refuses to allow for any minimum wage,” Dieter Schlenker, Taxi Deutschland’s chairman, said in a statement. Taxi associations and local authorities also have open legal cases against Uber in Berlin and Hamburg, though the company has won reprieves in those German cities until courts make a final ruling this year over whether Uber complies with local laws. In the Frankfurt case, which centered on whether its business was anticompetitive, Uber faced fines in Germany of up to $330,000 or a jail term of up to six month for a local employee, if it violated the temporary injunction.
