IOWA CITY — After listening to days of testimony — including from tearful female athletes staring down uncertain futures after the University of Iowa blindsided them in August with news it’s eliminating the swimming and diving for which they were recruited — a federal judge Tuesday effectively blocked the UI closure. At least for now. U.S. District Court Judge Stephanie Rose granted a preliminary injunction six UI female athletes brought against the school it accused not only of causing irreparable harm to their academic and swimming careers but of falling further out of compliance with Title IX of the federal education amendments of 1972 — which protects people from discrimination based on their sex.
