Argued: Pierce v. Society of Sisters - The Supreme Court will rule unanimously that parents cannot be forced to send their children to public rather than private schools, based on the idea that, parents have a fundamental liberty in deciding what happens to their children.
From the decision:
"...the Act of 1922 unreasonably interferes with the liberty of parents and guardians to direct the upbringing and education of children under their control. As often heretofore pointed out, rights guaranteed by the Constitution may not be abridged by legislation which has no reasonable relation to some purpose within the competency of the state.
The fundamental theory of liberty upon which all governments in this Union repose excludes any general power of the state to standardize its children by forcing them to accept instruction from public teachers only."
