Uber Technologies Inc. appealed a London regulator's decision to revoke the auto service's license as it seeks more settlement talks.
The ride hailing app filed documents at Westminster Magistrates' Court opposing the ruling.
Uber has filed an appeal against the decision by London authorities to deny it a licence to operate in London.
Transport for London (TfL) shocked the Silicon Valley firm last month by deeming it unfit to run a taxi service and refusing to renew its licence, citing its approach to reporting serious criminal offences and background checks on drivers.
"We hope to continue having constructive discussions with Transport for London", Uber said Friday in an emailed statement. "As our new CEO (Dara Khosrowshahi) has said, we are determined to make things right".
New global Chief Executive Dara Khosrowshahi met TfL Commissioner Mike Brown for talks earlier this month, which both sides said were "constructive" as the $70-billion firm tries to fix its relationship with the regulator.
The talks were described by both sides as "constructive". Transport for London (TfL) claims that the conduct of Uber, which has about 40,000 drivers and 3.5 million customers in the British capital, had raised concerns.
His predecessor, Travis Kalanick, left the company following allegations that managers didn't adequately address reports of sexual harassment. Khosrowshahi apologized for "the mistakes" the company had made.
Uber will challenge the licence decision "with the knowledge that we must also change", he said.
The debate over Uber's future has divided Londoners, with hundreds of thousands of people signing a petition urging the mayor to revoke the decision.
