Eleven female high school student-athletes today filed suit to compel the Minnesota State High School League to hold the State Girls' Hockey Tournament in the Xcel Energy Center in St. Paul, starting this season. The tournament is scheduled to take place in Ridder Arena, on the campus of the University of Minnesota. Ridder Arena, which was built as home arena to the U of M women's hockey team, holds about 2700 fans; Excel Center, where the boys' tournament is held, could hold as many as 18,000. The lawsuit alleges holding the tournaments at different venues is a violation of Title IX, which mandates equal athletic opportunity. Bob Gilbertson is one of the attorneys representing the families bringing the lawsuit; he's an attorney with Robins, Kaplan, Miller and Ciresi. He says he's heard the argument that Excel is just too big to hold an event like the girls tournament. But he says he doesn't agree.
