Uber has filed an appeal against the decision by London authorities to deny it a licence to operate in London.
Last month, Transport for London (TfL) refused Uber a new private hire licence, saying the ride-hailing firm was not fit and proper.
TfL said it took the decision on the grounds of “public safety and security implications”.
The appeal process could take months, during which time Uber can continue to operate in London.
“While we have today filed our appeal so that Londoners can continue using our app, we hope to continue having constructive discussions with Transport for London.
As our new CEO [chief executive] has said, we are determined to make things right,” an Uber spokesperson said.
TfL “noted” the appeal but said it would not be commenting before the hearings.
