NASCAR sued 23XI Racing and Front Row Motorsports, saying in court documents that the two companies want to eliminate the charter system.

NASCAR has filed a counterclaim against Michael Jordan-owned 23XI Racing and Front Row Motorsports alleging they “willfully” violated antitrust laws in connection with the most recent charter agreements.

NASCAR stated in court documents that the two teams and Curtis Polk “embarked on a strategy to threaten, coerce, and extort NASCAR into meeting their demands for better contract and financial terms.”
