The professor, Charles Nesson, has come to the defense of a Boston University graduate student targeted in one of the music industry's lawsuits. By taking on the case, Nesson hopes to challenge the basis for the suit, and all others like it.
Nesson argues that the Digital Theft Deterrence and Copyright Damages Improvement Act of 1999 is unconstitutional because it effectively lets a private group _ the Recording Industry Association of America, or RIAA _ carry out civil enforcement of a criminal law. He also says the music industry group abused the legal process by brandishing the prospects of lengthy and costly lawsuits in an effort to intimidate people into settling cases out of court.
Nesson, the founder of Harvard's Berkman Center for Internet and Society, said in an interview that his goal is to "turn the courts away from allowing themselves to be used like a low-grade collection agency."
