Johnny Blago is a high school student and Internetblogger. He blogs about the teachers and students at his school.His comments are normally inappropriate and usually offensive. Aweek before graduation he posted his top ten most annoying teacherswho need to get fired list. Upon reading the blog, the principalcalled Johnny into the office and asked him to remove the listimmediately because it was in violation of school rules. Johnnyrefused and was banned from attending the graduation ceremony untilit was removed. Johnny claimed the school violated his firstamendment rights and the school claimed he was in violation of theschool conduct code.

In the scenario, does the school have the right to banJohnny from graduation because of his blog?
