Lucan Battison court case

There has recently been a court case here in New Zealand between a year 12 student named Lucan Battison and St Johns College in Hastings. Lucan took his school to court about his hair. The school had suspended him because his hair was too long, but Lucan took his school to court because he thought that everyone had a right to have long hair. The rules state that his hair has to be off the collar and out of the eyes, but he wasn't breaking the rules at all. My opinion is that Lucan has a right to be himself and he should not have to cut his hair.
