College basketball's mid-major 2017 conference realignment has catalyzed major litigation.

As first reported by Forbes, the Horizon League has filed a $500,000 lawsuit against Valparaiso University and the Missouri Valley Conference. Valpo left the Horizon League on July 1 to join the Missouri Valley Conference after the Valley lost powerhouse member Wichita State to the American Athletic Conference. The Horizon League claims Valpo breached its contract with the conference when it maneuvered an exit from the league without giving a year's notice.

The Horizon League claims its bylaws -- which Valparaiso helped revise after that league lost flagship member Butler to the Atlantic 10 in 2012 -- mandate a one-year heads-up before a school can leave the conference. In absence of that, the exit fee is $500,000.

Valparaiso's official announcement that it would be leaving the Horizon League came on May 25. On June 27, the conference filed its lawsuit against its former school and the conference that was taking the Crusaders.
