Mel Tucker filed a lawsuit against Michigan State for what he sees as wrongful termination of his position as head football coach. Tucker claims in a federal suit filed Wednesday in Michigan that the school conducted an “improper, sham investigation” into the allegations, and disregarded his due process and the terms of his contract by firing him.

Tucker was fired in September after allegations of sexual harassment emerged against him. The university argued the allegations allowed them to end his deal with cause, meaning they wouldn’t have to pay the $80 million left on his contract.
