Whether the INS regulation violated substantive due process by keeping unaccompanied alien juveniles in institutional custody rather than releasing them to willing, unrelated responsible adults.
Holding
No. The regulation did not, on its face, violate substantive due process.
Reasoning
The Court carefully defined the asserted liberty interest. This was not a claim to freedom from shackles, jail cells, or all forms of custody. Children are ordinarily subject to some form of custody, and when parents or guardians are unavailable, government may assume custody or arrange for it. The claimed right was instead a right to placement with a willing private custodian rather than in a government-operated or government-selected child-care institution.
That asserted right was not fundamental. No tradition established a constitutional right of a child without an available parent, close relative, or guardian to private placement with an unrelated adult who was not the child's legal guardian. Recognizing such a right would also substantially federalize the administration of state orphanages and other child-care institutions.
Because no fundamental right was infringed, the regulation needed only a reasonable fit with a legitimate governmental purpose. The INS could reasonably seek to protect the welfare of children in its custody by relying on parents, close relatives, and legal guardians as presumptively appropriate custodians, while maintaining custody in licensed, humane shelter-care facilities when such persons were unavailable.
The Court rejected the claim that due process required a case-by-case determination of each child's best interests. The Constitution requires that minimum standards be met and that fundamental rights be protected, but it does not make the child's best interests the exclusive constitutional criterion for every governmental custodial decision. The agency could account for its limited child-placement expertise and resources when choosing among otherwise permissible ways to protect juveniles.
The conclusion was reinforced by Congress's broad immigration authority. Congress may detain aliens suspected of unlawful entry pending deportation proceedings, and the differing treatment of aliens and citizens, as well as the preference for close relatives and legal guardians over unrelated adults, survived rational-basis review. This facial challenge also required respondents to show that no set of circumstances existed under which the regulation could be valid; they did not do so.
