In Chapter 10, Robert Berry discusses legal issues regarding plagiarism and academic cases of intellectual dishonesty.
From the Introduction: Colleges and universities with plagiarism policies that are fundamentally fair—and that are applied consistently—enjoy three significant advantages over those that do not. First, these schools enjoy greater legitimacy in the eyes of the people who must live with their decisions. They exercise genuine moral authority in their decision making, which is much more consistent with the goals of education, and they avoid the exercise of raw power that often accompanies ad hoc decision making. Second, educational institutions with fair policies are less likely to be sued and, if sued, are less likely to lose. Third, the same procedures that ensure fairness also promote the effectiveness of university prohibitions against plagiarism by creating an educational milieu where a school's response to plagiarism is predictable and reliable.
