Explanation:

The reasoning why they went to court was because they argued that their First Amendment right to freedom of speech was being taken away. Tinker argued that they weren't doing any harm to anybody by wearing the arm bans and it was their right to do so, because of the First Amendment. The court ruled in favor of Tinker in end.
