White was found guilty of manslaughter by a 12-person jury in the NSW Supreme Court on November 27.
The former senior constable had been sidelined from his job with pay for 18 months after charges were laid, but was suspended without pay following his conviction.
White was then removed from the police force on December 3.
He has launched legal action against police, filing for a review of his dismissal in the Industrial Relations Commission of NSW.
NSW Police confirmed the legal filing in a statement on Monday, saying it has been advised of the action but "given the matter is before the IRC no further comment can be made."
White is awaiting sentencing.
