France in January banned the low-cost service, which puts customers in touch with private chauffeurs at budget prices, after furious taxi drivers protested around the country.
The San Francisco-based company filed a complaint with the European Union (EU) over the ban and also contested it at France's constitutional council.
However as the ban was hard to police, Uber kept operating the service in France, leading to a spate of violent protests in June that saw cars set alight and a number of Uber drivers and passengers attacked.
The constitutional council said the ban was in line with laws against "an organised system that puts clients in touch with people" offering taxi services but which are not part of an official transport company.

Ber said the ruling was "obviously disappointing".
"We will continue to work with the government to define a modern and pragmatic regulatory framework," the company said in a statement, adding that the decision did not impact its professional driver service available via the Uber app.
