The summary judgment follows a decision by London's transport authorities not to pursue a case against Uber in June this year.
The San Francisco-based firm allows passengers to summon cars using an app on their smartphones and calculates the fare en route. It is often significantly cheaper than rival taxi companies.
But taxi drivers argue that Uber has fewer regulatory burdens placed upon it than they do, and poses unfair competition.
The company - which is backed by Google and the bank Goldman Sachs, among others - has been the subject of protests by taxi drivers in many European cities, including Berlin, Paris and London.
Only last week, Uber said it was planning to rapidly expand its German operation.
