Joseph Corlett is suing Oakland University for $2.2 million for kicking him out after he wrote an essay called "Hot for Teacher" about one of his instructors, The Detroit Free Press  reported. The university is not commenting on the lawsuit. His instructor had encouraged students to be frank in their essays, but in this case, some believed he went too far. Corlett maintains that his free speech rights were violated. When Inside Higher Ed wrote about the dispute last year, some commenters  said that they sympathized with the instructor and would have been concerned by the student's essay.
