Do squatters, pirates, and protesters improve the law? Professor Sonia Katyal, of Fordham Law School, says that they do in her new book, Property Outlaws (Yale University Press, 2010). She and coauthor Eduardo Peñalver, a professor at Cornell Law, contend in the case of both tangible and intellectual property law, particularly copyright law, some forms of disobedience can often lead to an improvement in legal regulation.  An important conclusion of the book is that a dynamic between the activities of “property outlaws” and legal innovation should be cultivated in order to maintain this avenue of legal reform.
