Former Papa John’s chairman John Schnatter has accused the company’s CEO of lying to oust Schnatter and save his own job, according to a Delaware Court of Chancery lawsuit that was unsealed on Thursday.

In a redacted complaint, Schnatter said Papa John’s chief executive Steve Ritchie launched a “false and defamatory” campaign accusing Schnatter of racism, causing the company to suffer “irreparable harm” amid a battle for control with its outspoken founder.
