Moody v. Daggett
The Court ruled that a federal parolee who is already imprisoned for a new crime is not constitutionally entitled to an immediate parole-revocation hearing just because the Parole Board issued a violator warrant and filed it as an unexecuted "detainer."
The decision means parole authorities can lawfully wait until a parolee finishes his new sentence before deciding whether to revoke his earlier parole, because the loss of liberty that triggers a hearing right happens only when the warrant is actually executed and the person is taken into custody under it.
“we cannot say that the parole violator warrant has any present or inevitable effect upon the liberty interests which Morrissey sought to protect”
The Court's reasoning that an unexecuted warrant does not yet take away any protected liberty.
How it got here: The prisoner sought federal habeas relief after the Board refused to execute the warrant promptly; a district court dismissed the case and the Tenth Circuit affirmed.
The Case in Depth
What happened
A man convicted of rape on an Indian reservation was paroled with years left on his sentence. While on parole he killed two people and was convicted of manslaughter and murder, receiving new concurrent sentences. The Parole Board issued but never served a warrant for violating his earlier parole, instead filing it as a "detainer" and deciding to wait until his new sentence ended before deciding whether to revoke parole.
The question before the Court
If a federal parole board issues a parole-violator warrant but only files it as a "detainer" without serving it, must the parolee get an immediate hearing?
Why it matters
Federal prisoners who commit new crimes while on parole can now be left for years with an unresolved parole-violation warrant hanging over them, without any court hearing, while they serve their new sentence. Parole authorities gain broad discretion over timing, and prisoners lose the chance to force an early hearing or seek sentences that run concurrently.
What changes now
The ruling is final on the constitutional question, but it does not end the underlying parole dispute — the Parole Commission remains free to decide later, once the man finishes his homicide sentences, whether to revoke his earlier parole, dismiss the warrant, or grant credit toward concurrent service. Other circuits that had ruled the opposite way on this question are now overridden by this nationwide rule.
What this does not decide
The Court expressly did not decide what process, if any, must eventually accompany a final parole-revocation decision, nor whether delay could ever become so extreme or purposeful as to violate due process; it addressed only whether an immediate hearing is required upon issuance of an unexecuted warrant.

Dissent — Justice Stevens
“This position, I submit, can be tenable only if one assumes that the constitutional right to a fair hearing includes no right whatsoever to a prompt hearing.”Stevens's objection that letting a warrant sit unexecuted for years ignores any right to promptness.
Justice Stevens argued that the parole revocation process begins the moment the Commission issues the warrant, so constitutional protections attach then, and the real question is whether the parolee has a right to a reasonably prompt hearing. Drawing on speedy-trial precedents and the historical roots of prompt-justice guarantees, he argued that indefinite delay of up to 10 or 20 years is fundamentally unfair, would corrode the parolee's ability to prepare a defense, and would let prison officials treat detainers as a source of ongoing uncertainty and harm without any check.

How the Court got there
The legal reasoning, step by step
- The Court reviewed its earlier ruling in Morrissey v. Brewer, which held that parole is a protected liberty interest that cannot be revoked without a fair hearing, and asked whether that hearing right is triggered merely by issuing an unexecuted warrant.
- The Court identified execution of the warrant and the parolee being taken into custody under it as the specific event that starts the loss of liberty Morrissey was designed to protect, not the mere filing of the warrant as a detainer.
- Applying that rule here, the Court found that the man's current confinement and any loss of freedom came from his own homicide convictions, not from the outstanding, unserved warrant, so no liberty interest was yet being taken away.
- The Court reasoned that the Board still retained full discretion to dismiss the warrant, decline to revoke parole, or later grant the practical equivalent of concurrent sentences, so waiting caused no irreversible harm to the man's legal position.
- The Court also reasoned that delaying the hearing until the new sentence ends actually improves the accuracy of the parole board's prediction about whether the person can be trusted back in society, because his prison record during the new sentence becomes available evidence.
- Concluding that no present deprivation of liberty had occurred, the Court held that the Constitution imposes no duty on the parole authority to hold a hearing before it executes the warrant and takes the parolee back into custody.
