 In 1970, he established the Constitutional Litigation Clinic as part of the law school's curriculum.Under his guidance, the clinic litigated the first police surveillance cases in the nation; battled the FBI over the investigation and maintenance of files on two precocious New Jersey high schoolers who corresponded with "the wrong persons"; defended affirmative action programs up to the United States Supreme Court; challenged the New Jersey State Police for stopping and searching "long-haired travelers" on the state's highways; argued for the right of the homeless to vote and to have access to public library facilities; and protected the right of grassroots advocacy groups to take their messages door-to-door and to privately owned shopping malls.He still is associated with the clinic.
