“ If a single parent who is struggling to raise a child is faced with visitation demands from a third party, the attorney's fees alone might destroy her hopes and plans for the child's future. Our system must confront more often the reality that litigation can itself be so disruptive that constitutional protection may be required; and I do not discount the possibility that in some instances the best interests of the child standard may provide insufficient protection to the parent-child relationship. ”

“ To say that third parties have had no historical right to petition for visitation does not necessarily imply, as the Supreme Court of Washington concluded, that a parent has a constitutional right to prevent visitation in all cases not involving harm. True, this Court has acknowledged that States have the authority to intervene to prevent harm to children, see, e.g., Prince, supra, at 168-169; Yoder, supra, at 233-234, but that is not the same as saying that a heightened harm to the child standard must be satisfied in every case in which a third party seeks a visitation order. ”

“ In short, a fit parent's right vis-à-vis a complete stranger is one thing; her right vis-à-vis another parent or a de facto parent may be another. The protection the Constitution requires, then, must be elaborated with care, using the discipline and instruction of the case law system. ”
