This paper deals with the legal aspects of student rights and of the various forms of expression (riots, demonstrations, speeches, and writings) pertinent to student activism, militancy, or agitation. It cites examples of such activities, along with decisions handed down by school authorities and local, state, and federal courts. The most recent case reviewed is Barker v. Hardway in the spring of 1968. Following the trends indicated by these decisions, the author offers guidelines to college administrators. They cover general principles such as avoidance of ambiguity or inconsistency, wide dissemination of information on the college rules, the extent of authority over behavior on or off the campus, the distinction between substantive and procedural due process, and the proper conduct of formal and informal hearings. Recommendations include: (1) a spirit of reason on the part of all concerned, (2) the formulation and enforcement of just rules and regulations for freedom of expression on campus, and (3) the channelling of student dissent into constructive activism, leading to increased academic freedom for all.
