The case first began in February 2018, when a Wall Street Journal story accusing Wynn of multiple cases of sexual misconduct in the workplace forced him to resign as CEO of the company.
Wynn Resorts has already paid $55m in fines related to the allegations against Wynn.
A hairstylist formerly employed by Wynn Resorts filed the latest lawsuit against the operator last month, accusing Wynn executives of sending an undercover spy to his salon after he made public allegations of sexual misconduct against the former CEO.
Wynn’s attorney, Don Campbell, now claims the board is overstepping its statutory authority by insisting on personal fines for the former CEO, despite the fact he has left the company and divested himself of ownership.
Campbell said: "Such a draconian concept of lifetime jurisdiction is found nowhere in the statutes or regulations relied upon by the NGCB.
"It is clear the Nevada legislature neither expressly nor implicitly authorised the Commission and NGCB to discipline persons who no longer have any involvement with gaming licensees."
