The BBC producer punched by Jeremy Clarkson is suing the former Top Gear host and the broadcaster for racial discrimination.
Lawyers for Clarkson and the BBC had a closed-door hearing with Oisin Tymon at a London employment tribunal on Friday.
Mr Tymon was punched by Jeremy Clarkson during a row over food.
The BBC refused to renew Clarkson's contact after the altercation.
Clarkson has signed a deal with Amazon to present a new show with Top Gear pals James May and Richard Hammond.
Mr Tymon's lawyers at Slater and Gordon confirmed the legal action to ITV News but declined to comment on the case.
ITV News has approached Mr Clarkson's representative for a comment.
A BBC spokesperson said: “We will be responding to this claim but will not be commenting further at this time.”
