Constitutional rights have never been absolute. For example, Colorado requires parents to seek medical help for seriously ill or injured children, even if the parents believe faith healing and their religion rejects modern medicine. If the parents' constitutional rights truly pierced all opposition, the law could not stand. But protecting the safety of children is a compelling interest, so the law is upheld over the parents' religious objections. Similarly, the PRA cannot undo child abuse laws, even if abusers invoke it.
Government has a compelling interest in prohibiting and punishing harm to children.
Courts will continue to enforce such laws. Neither will parents be able to veto school materials or micromanage curriculum. Parents' rights to direct their children's education does not include control over other children's education. Logically, the PRA allows parents only to withdraw their child form objectionable activities, not to block the activities. Similarly, parents could not dictate offerings at public libraries, because they are free to monitor their own children's library use.
