Jack Montague, the former Yale basketball captain who was expelled for alleged sexual misconduct earlier this year, has filed a lawsuit against the Ivy League university, claiming the school not only violated Title IX proceedings, but also defamed him and denied him a fair hearing during the fall 2015 semester.

“Yale was under enormous pressure to show it took seriously female students’ complaints of sexual assault and to counter the perception that it was inappropriately lenient in its discipline of male students accused of sexual misconduct,” wrote William Dow III, of Jacobs & Dow in New Haven, Montague’s attorney. The suit, filed in Connecticut federal court, alleges that Yale administrators “seized the opportunity to make an example of [Montague] because he was one of the most prominent male figures on campus.”
