Controversial taxi-hailing app Uber has agreed to pay the state of California $7.6m (£5.3m) in fines for failing to share data about trips taken using the service that are required by transportation authorities and regulators.

In order to operate a transportation network company, which Uber legally counts as in California, the firm has to provide information on the number of trips taken broken down by postal code, as well as how much riders have paid, data on accidents and how many wheelchair-accessible vehicles have been requested.

A judgement on the case was originally made last year by a California judge, ruling that the company had violated state rules for transport companies, but Uber challenged the decision. The California Public Utilities Commission upheld the ruling, finding the company in contempt and raising the fine from the original amount of $7.3m.

Uber has stated that it has given the state all the information that was requested, and plans to appeal the fine amount in court, after disagreements over how it was calculated.

The company has found itself facing increasing legal challenges both at home in the US and abroad, as it disrupts traditional taxi services. Issues with both how the firm operates (including whether drivers count as employees, and how the company carries out background checks) and its legal status as a transportation provider have resulted in numerous challenges from both authorities and rival firms.
