France’s top constitutional court has ruled that Uber’s lowest-cost service can be banned, upholding legislation passed amid sometimes violent protest by taxi drivers. In a ruling Tuesday, the panel upheld French legislation that outlawed the UberPop service, which the company suspended over the summer in hopes of defusing an escalating legal dispute with the government.
