LONDON: An American law professor is suing his university after it banned him from teaching over comments he made about Israel, The Guardian reported. Ramsi Woodcock’s lawsuit, filed in federal court against the University of Kentucky, is part of a growing backlash against US universities over a clampdown on pro-Palestine speech and activities. His suit argues that his first amendment and due process rights were violated when the university placed him under investigation in July, days after he was promoted to full professorship.
