A judge recommended that Uber pay a $7.3 million fine and meet certain reporting requirements within 30 days or be suspended from operating in California.
The ruling, released Wednesday by the California Public Utilities Commission (CPUC), says that Uber failed to give the agency information on how many rides were requested and accepted within each California zip code, how many users requested handicap accessible vehicles, and the cause of each accident involving an Uber driver.
Uber plans to appeal the ruling, telling NBC News that the company has "already provided substantial amounts of data" to the CPUC.
"Going further risks compromising the privacy of individual riders as well as driver-partners," Uber spokesperson Eva Behrend told NBC News in a statement. "These CPUC requests are also beyond the authority of the Commission and will not improve public safety."
Uber service will not be suspended while the company's appeal is heard, meaning it could be longer than 30 days -- if ever -- before Uber has to stop operating in California.
The data requests are part of a 2013 law meant to ensure that ride-hailing apps like Uber, Lyft, and Sidecar don't discriminate against people because of handicaps or where they live. According to the CPUC, Uber is the only such company to fail to meet their requirements.
