From Boston.com:

The Atlantic Coast Conference has filed a lawsuit against Maryland seeking full payment of the approximately $53 million exit fee for the school’s move to the Big Ten. According to the 10-page lawsuit, the ACC said the school must pay $52,266,342, which is three times the league’s annual operating budget for the 2012-13 season. The lawsuit also states that Maryland president Wallace D. Loh has ‘‘refused to provide assurance’’ that the school will pay the exit fee and ‘‘has made it clear that defendant Maryland does not intend to pay the amount.’’

So, it seems the ACC is pro-active. They want the money, in full. Or else. I welcome this news, it shows to me that this is NOT the Big East 2.0
