The man who helped Abigail Fisher sue the University of Texas at Austin for discrimination in a case that reached the U.S. Supreme Court twice is suing UT-Austin once again.

This time, he claims the university's use of affirmative action violates the Texas Constitution, not the U.S. Constitution.

Edward Blum's group Students for Fair Admissions filed the suit in Travis County court Tuesday.
