Whether the Fourteenth Amendment protects a fit parent's authority to decide with whom her children will associate and visit.
Holding
Yes. The Due Process Clause protects the fundamental right of parents to make decisions concerning the care, custody, and control of their children.
Reasoning
The Court treated parental authority over child rearing as one of the oldest fundamental liberty interests protected by substantive due process. Meyer, Pierce, Prince, Stanley, Yoder, Parham, Santosky, and Glucksberg all recognize, in different settings, that parents have constitutionally protected authority to direct their children's upbringing, education, care, and custody.
This protection rests in part on the traditional presumption that fit parents act in their children's best interests. Parents ordinarily possess the maturity, experience, responsibility, and natural bonds of affection needed to make difficult decisions for their children; absent evidence of unfitness or inadequate care, the State generally has no reason to second-guess those decisions.
