A federal judge has ruled that the University of Wyoming must allow 1960s radical William Ayers to speak on the school's campus in Laramie.
U.S. District Judge William Downes issued the ruling Tuesday after a Monday court hearing.
The university had cited threats of violence in not allowing Ayers to speak at a campus event planned for Wednesday. Downes says such threats can't be used as a reason to deny Ayers' right to speak on campus.
Ayers now plans to speak at UW on Wednesday at the invitation of a student.
Ayers is a professor at the University of Illinois-Chicago. He co-founded an anti-war group that claimed responsibility for a series of nonfatal bombings to protest U.S. foreign policies during the Vietnam War era.
