Tinker v.Des Moines School District一案是美国宪法史上的重要案例。美国联邦最高法院通过此案,重新讨论了象征性表达的言论地位,并且认为应对于佩戴袖章这样的象征性表达行为施予第一修正案的言论自由之保护。法院还进行了校园管理秩序与表达自由两种价值的取舍,认为应对校方限制表达自由之禁令进行程序与实质的严格标准审查。最后,此案还讨论了学校作为合格公民培训所的重要职责,并且再一次对于校园内的表达自由给予了肯定与保护。 Tinker v. Des Moines School District case is an important case in the history of the United States Constitution. The Supreme Court of the United States passed the case to re-discuss the symbolic position of speech and to consider the protection of the freedom of speech to which the First Amendment was imposed on such symbolic expressions as armbands. The court also conducted a choice of two values: order management and freedom of expression in the campus. They held that the ban on freedom of expression that the school restricted its freedom should be subject to rigorous standards and procedures. Finally, the case also discussed the school’s role as a qualified citizen training center and reaffirmed and protected once again the freedom of expression on campus.
