Whether state prisoners may use 42 U.S.C. § 1983 to seek restoration of good-time credits when success would mean immediate or speedier release from prison.
Holding
No. When a state prisoner challenges the fact or duration of physical imprisonment and seeks immediate or speedier release, federal habeas corpus is the exclusive federal remedy.
Reasoning
Habeas corpus has historically been the specific remedy for a person claiming unlawful physical restraint and seeking release. The prisoners alleged that the unconstitutional cancellation of their credits caused, or would cause, unlawful continued imprisonment. Their requested restoration of credits would produce immediate release in these cases, and would fall within habeas even if it merely shortened future confinement.
Section 1983 is phrased broadly, but the more specific habeas statutes govern where a state prisoner attacks the validity or duration of custody. Congress required exhaustion of adequate state remedies before federal habeas relief may be granted. Allowing prisoners to obtain the same release-related relief under the general civil-rights statute would permit them to evade that express condition simply by changing the label on their pleadings.
The Court described this category as the core of habeas corpus: claims directly challenging the constitutionality of present or future physical confinement and seeking release or a reduction in its duration. Administrative action by prison officials, rather than a state-court conviction, does not place the claim outside that core when the relief sought is release-related.
