The Big East sued TCU on Monday, claiming the school has failed to pay its $5 million exit fee to join the Big 12.
The lawsuit was filed in federal court in Washington. Big East spokesman John Paquette said the league had no comment.
TCU agreed to join the Big East in 2010, but left for the Big 12 last October without ever having played as members of the league. As part of its agreement to join the Big East, the league contends TCU agreed to pay a $5 million exit fee if it reneged on its deal. In the lawsuit, the Big East says it has demanded payment, and TCU has refused.
For those scoring at home, the Big East has now been involved in four lawsuits in the last calendar year. First, West Virginia sued the Big East to join the Big 12 without serving a 27-month waiting period. The Big East counter-sued. The two sides were able to come to a resolution without going to trial.
Last month, Pitt sued the Big East to be able to join the ACC in time for the 2013 season.
