A federal trial begins this week on what could be a key legal case for Title IX of the Education Amendments of 1972. The case involves a suit against Quinnipiac University over a move to eliminate its women's volleyball team. The university has denied wrongdoing. The suit charges that the university counts its men's and women's rosters in ways to create a false impression of relative gender equity. One of the issues in contention, as the Associated Press reported, is whether the university can count its "competitive cheer squad" as an athletic team.
