The Russ College of Engineering and Technology of Ohio University announced in a press conference that it had found "rampant and flagrant plagiarism" in the theses of mechanical engineering graduate students. Faculty singled out for "ignoring their ethical responsibilities" included Jay Gunasekera, chair of the department. Gunasekera was prohibited from advising students. He filed a suit against Dennis Irwin, the dean of Russ College, for violating his due process rights. What does due process require in these circumstances? Why?
