Explanation:

The 1988 judgment of the case between Hazelwood v. Kuhlmeier was a case the supreme court gave affirmation that the school authority has the right to censor or exercise retrain over publications by students. The court gave a decision that such student newspapers or journals are subject to the First Amendment to control of what is being expressed by the students before publication because the school control and sponsored the publication. The case was a result of the articles written by the students on teen pregnancy and divorce which the principal of the school (Hazelwood East High School in St. Louis County, Missouri) removed the articles.

NOTE!!! That the court also stated that the said publication was not meant for public publication in a public forum which could bring up diverse views on the articles.

However, in the case of Tinker v. Des Moines Independent Community School District 1969 which the supreme court affirmed the rights of the students to freedom of expression in public schools. This case was a  result of some set of the student using an armband in protest against the war in Vietnam.

In comparing both, it must be stated that the free speech was limited in the Hazelwood ruling WHILE the Tinker ruling empowered the free speech rights of students.
