Boise State is asking a court to declare that the school does not owe a $5 million penalty for cancelling its entry into the Big East Conference.
The university announced Monday it had filed a lawsuit in Boise after a representative of what will soon be the American Athletic Conference said the conference intended to sue the university.
Boise State signed an agreement in December 2011 to join the Big East in July 2013 for football. However, the school says the conference lost three-quarters of its members over the next year, failed to add more football schools west of the Mississippi and lost its guaranteed spot in BCS bowls.
Boise State announced last December that it would remain in the Mountain West Conference.
University President Bob Kustra argues the conference the Broncos agreed to join no longer exists.
