Google’s driverless car division, Waymo LLC, is getting its holy grail of discovery.

The U.S. Court of Appeals for the Federal Circuit on Wednesday rejected Anthony Levandowski’s attempt to block production of a due diligence report in which he may or may not have acknowledged illegally downloading driverless car technology files from Google before leaving the company. Levandowski formed his own autonomous vehicle companies in 2016 and sold one of them to Uber for $680 million.
