Court cases involving student discipline, especially in regard to student publications and dress and appearance, is the subject of this chapter. The introduction discusses the doctrine of in locus parentis, the celebrated Supreme Court case of Tinker, and the minimum essentials for enforcing rules of student conduct. The first half of the chapter on publications considers the procession of student discipline cases that have arisen since 1968. It surveys the restraints put on the content of publications, especially publications containing criticism of school authorities, controversial issues, and obscenity and vulgarity. An array of cases is also discussed concerning the prior restraint school authorities can exercise on the content of publications. The second half of the chapter--issues of dress and appearance--discusses the question of whether a student can be punished for refusing to conform to a dress code. The mixed opinions evolving from both federal and state courts, primarily concerning male hairstyles and beards, are the basis for discussion. (Author/LD)
