Whether the Parratt-Hudson doctrine can apply to an alleged deprivation of liberty, rather than merely property.
Holding
Yes. Parratt and Hudson are not categorically confined to property deprivations, although the seriousness of the liberty interest remains central to the due-process analysis.
Reasoning
The Due Process Clause protects both liberty and property, and the Court rejected a categorical rule that postdeprivation remedies can never suffice when liberty is at stake. Parratt and Hudson turn principally on whether the State could practicably provide meaningful process before the deprivation, not on whether the interest is labeled property or liberty.
Burch's interest in avoiding confinement in a mental hospital was unquestionably substantial. Civil commitment is a major curtailment of liberty, and Burch alleged five months of confinement without either valid consent or the protections associated with involuntary placement. But the existence of a liberty interest did not itself resolve whether predeprivation procedures were feasible.
