This decision struck down a state law prohibiting any instructor, either in a public or a private school, from teaching in a language other than English. The Court took this action because of the arbitrary interference from state officials of the right of parents to provide education for their children as they saw fit. The statute was arbitrary because it bore no relationship to a legitimate state purpose and violated the part of the Due Process clause of the 14th Amendment to the Constitution that says no person may be deprived of liberty without due process of law. In this case, the right of the parents to employ a teacher to instruct their children in their native language fell under the right to determine how they were to be educated.
