 Parental rights’ content, extent, and relation to parental obligations is determined by the underlying theory of why parents possess such rights. On the child-centered or fiduciary model, parental rights piggyback on parental responsibilities to children, which are morally fundamental. One such theory is Blustein’s “priority thesis.” According to the priority thesis, parents acquire rights in order to carry out their responsibilities; thus responsibilities are morally prior to rights (Blustein 1982, 104–114). As Archard writes, “A parent can choose for his child, and exclude others from the making of these choices, only in the service of and thus constrained by a duty to care for the child. It is in the first instance because a dependent child must have decisions made for it that a designated parent is entitled to make those decisions.” (Archard 2010, 108; see also Brennan and Noggle 1997; Austin 2007).
