The conferences were unable to resolve their differences with a mediator. The next step is a hearing on the Mountain West’s motion to dismiss.

The Pac-12 and Mountain West are headed to court. The conferences were unable to reach a settlement in the legal dispute over exit fees and poaching penalties tied to the Pac-12's acquisition of five Mountain West schools, and they made a joint filing Tuesday to ask for a hearing on Sept. 9.

A lawsuit filed by the Pac-12 against the Mountain West over approximately $150 million in exit and poaching fees is headed to court, according to a document filed.
