Players and the coach of the volleyball team at Quinnipiac University, backed by the Connecticut chapter of the American Civil Liberties Union, have sued the university in federal court, charging that its plans to eliminate the sport violate Title IX of the Education Amendments of 1972. The suit charges that, even before proposing to eliminate the sport, the university failed all of the possible tests for compliance with Title IX. The ACLU released the suit and a letter sent to the university last month requesting discussions on the issue. University officials told the Associated Press they would not comment because the matter is in litigation.
