Paris: Uber has filed a second complaint against a French law that the online taxi-booking service says favours regular taxis at its expense, French newspaper Les Echos said on Tuesday.
Uber last November filed a first complaint with the European Commission, the first of a series of challenges to EU member states reluctant to open their markets to the U.S. firm.
French business daily Les Echos, which says it has seen a copy of the complaint, said Uber`s aim was to put pressure on the European Commission so that it quickly opens an investigation.
Launched in California four years ago, the service has rapidly become popular in a number of countries because it often undercuts established taxi and minicab services.
Uber did not immediately reply to a request for comment.
