The former commissioner of rapper Ice Cube’s three-on-three basketball league is seeking access to corporate records in connection to claims its co-founders made him a scapegoat for fraud and mismanagement within the organization.

Roger Mason, a former National Basketball Association player and players’ union executive, filed a complaint in Delaware Court of Chancery Monday saying Jeffrey Kwatinetz worked with celebrity lawyer Mark Geragos to oust Mason from the Big3 basketball league after its inaugural season. Mason accuses Kwatinetz of using “horrible racial slurs” to disparage the league’s black players and prominent Middle Eastern investors.
