Release Pending Appeal

By Elizabeth Franklin-Best, Esq., and Christopher Zoukis, JD, MBA

Can you be released pending a federal appeal?

Usually not. In a federal criminal case, 18 U.S.C. § 3143(b) directs that a person convicted, sentenced to imprisonment, and appealing “be detained, unless” the court makes two specific findings — no flight risk or danger by clear and convincing evidence, and that the appeal raises a “substantial question” likely to change the outcome. The presumption runs toward detention.

Key takeaways on release pending appeal

• The phrase “appeal bond” is mostly a civil term. The federal criminal question is release pending appeal, and the governing statute is § 3143(b).
• The statute’s default is detention. Release is the exception, and the defendant has to earn both findings.
• A “substantial question” is not the same as a non-frivolous one, and circuit formulations of the phrase differ.
• For certain offenses, § 3143(b)(2) makes detention effectively mandatory.
• Even then, § 3145(c) allows release on a clear showing of “exceptional reasons why such person’s detention would not be appropriate.”
• Review of a release or detention order moves fast under Fed. R. App. P. 9, and the statute says such appeals “shall be determined promptly.”

The presumption of detention and the two-part test

This is the citable core of the page: the statute’s own structure, quoted.

Element	What § 3143(b) requires	The statutory language
The default	Detention	The judicial officer “shall order that a person who has been found guilty of an offense and sentenced to a term of imprisonment, and who has filed an appeal or a petition for a writ of certiorari, be detained, unless” the findings below are made
Finding 1 — risk	Not a flight risk and not a danger, by clear and convincing evidence	“by clear and convincing evidence that the person is not likely to flee or pose a danger to the safety of any other person or the community if released under section 3142(b) or (c) of this title”
Finding 2 — the appeal	Not for delay, and raising a substantial question likely to produce one of four outcomes	“that the appeal is not for the purpose of delay and raises a substantial question of law or fact likely to result in—”
Outcome (i)	Reversal	“reversal”
Outcome (ii)	New trial	“an order for a new trial”
Outcome (iii)	A non-custodial sentence	“a sentence that does not include a term of imprisonment”
Outcome (iv)	A sentence shorter than the time already served plus the expected appeal	“a reduced sentence to a term of imprisonment less than the total of the time already served plus the expected duration of the appeal process”
If (iv) applies	Detention ends when the likely reduced sentence expires	The judicial officer “shall order the detention terminated at the expiration of the likely reduced sentence”
Who bears the burden	The defendant, on both findings	The statute frames detention as the rule and the findings as the exception
Mandatory-detention offenses	Release effectively unavailable	§ 3143(b)(2): the judicial officer “shall order” detention for a person convicted in a case described in § 3142(f)(1)(A), (B), or (C)
The safety valve	Release still possible on exceptional reasons	§ 3145(c): a person subject to detention under § 3143(b)(2) who meets the § 3143(b)(1) conditions “may be ordered released, under appropriate conditions … if it is clearly shown that there are exceptional reasons why such person’s detention would not be appropriate”

Read the structure rather than the individual findings. The statute does not ask whether release would be reasonable. It commands detention and then carves out a narrow exception, and every word of the carve-out has to be satisfied.

Applied Insight — Elizabeth Franklin-Best, Esq., Principal Attorney: The finding that decides most of these motions is the second one, and specifically the word “likely.” It is not enough that the appeal presents a real issue. The issue has to be one that, if it goes the defendant’s way, is likely to produce reversal, a new trial, a non-custodial sentence, or a sentence shorter than the time already served plus the appeal. An issue that would produce a remand for resentencing to roughly the same term does not satisfy that clause, however strong it is.

“Appeal bond” is a civil term — here is why that matters

If you searched for “appeal bond,” most of what you found was about civil litigation, and it does not apply to you.

In a civil case, a losing party who wants to stop the winner from collecting the judgment while an appeal runs posts a bond — often called a supersedeas or appeal bond. The mechanics come from Fed. R. Civ. P. 62 and, on the appellate side, Fed. R. App. P. 8, which governs a stay or injunction pending appeal and expressly contemplates that “[t]he court may condition relief on a party’s filing a bond or other security in the district court.” That is a money mechanism: the bond protects the judgment creditor.

In a federal criminal case, there is no equivalent instrument that buys a defendant’s liberty. Nobody posts an appeal bond to stay a prison sentence. Custody pending appeal is governed by § 3143(b), and it turns on judicial findings about risk and about the merits of the appeal — not on money. Financial conditions can be part of a release order if release is granted, under 18 U.S.C. § 3142(c), but they are conditions attached to release, not the thing that produces it.

	Civil “appeal bond”	Federal criminal release pending appeal
What it protects	The money judgment	Nothing — it is about custody
Governing authority	Fed. R. Civ. P. 62; Fed. R. App. P. 8	18 U.S.C. § 3143(b)
What you post	A bond or other security	Not applicable
What decides it	Adequacy of the security	Judicial findings on risk and on the appeal’s merits
Default	Stay is commonly available on adequate security	Detention

Getting the vocabulary right is not pedantry. A family that goes looking for a bondsman after a federal sentencing is looking for something that does not exist, and losing days doing it.

What “substantial question” means

This is the contested phrase, and the honest answer has a caveat in it.

A “substantial question” is more than an arguable one and less than a question the defendant is likely to win. The general sense across the federal courts is that it must be a close question — one that could very well be decided the other way — rather than a routine or clearly foreclosed one. It does not require counsel to represent that the court below was wrong, and it does not require the district judge who imposed the sentence to conclude that they erred.

The caveat matters: the circuits have articulated this standard in different words, and the formulation that governs your case is your circuit’s own. A page that presents one circuit’s phrasing as the national test is doing you a disservice, and this page will not do it. When counsel briefs a § 3143(b) motion, the first research task is the controlling formulation in the relevant circuit. See federal appeals court for how circuit law works.

What is common ground everywhere is the second half of the clause: the substantial question must be “likely to result in” one of the four listed outcomes. Both halves have to be satisfied, and the second is where well-founded motions most often fail.

Where the motion is filed, and how it is reviewed

The motion goes to the district court first — ordinarily the judge who imposed the sentence, and often it is made orally at sentencing and then renewed in writing.

If the district court denies release, review lies in the court of appeals under Fed. R. App. P. 9, which governs release in a criminal case both before and after judgment of conviction and requires the district court to state in writing, or orally on the record, the reasons for its order — a requirement that matters, because an order without reasons is difficult to review and is itself challengeable.

The governing statute also sets the pace. 18 U.S.C. § 3145 provides for review of a release order under subsection (a) and appeal from a detention order under subsection (b), and says of each that the motion or appeal “shall be determined promptly.” Release proceedings are not on the ordinary appellate timetable; they are meant to move.

Because the underlying appeal itself commonly takes most of a year — the median from notice of appeal to final order was 10.2 months for appeals terminated on the merits in the 12 months ending September 30, 2025 (AO Table B-4A) — the practical stakes of a release motion are measured in months of custody. See how long does an appeal take.

What Rule 9 requires of the district court

One requirement in Fed. R. App. P. 9(a)(1) is worth knowing because it creates leverage: “The district court must state in writing, or orally on the record, the reasons for an order regarding the release or detention of a defendant in a criminal case.”

That obligation applies to a denial as much as to a grant. An order that simply denies release without reasons does not give the court of appeals anything to review, and the rule’s own committee note explains that the party seeking review “must supply the court of appeals with the same information required by subdivision (a)” plus “information about the conviction and the sentence.” Asking the district court to state its reasons on the record at the time of denial is therefore both proper and practically useful.

Rule 9 also confirms two things about the appellate court’s role. Rule 9(a)(3): “The court of appeals or one of its judges may order the defendant’s release pending the disposition of the appeal.” And Rule 9(c): “The court must make its decision regarding release in accordance with the applicable provisions of 18 U.S.C. §§ 3142, 3143, and 3145(c).” The express inclusion of § 3145(c) in that list is a useful signal — the exceptional-reasons provision is part of the framework the court of appeals applies, not an afterthought.

Procedurally, Rule 9(b) provides that a party may obtain review of a post-judgment release order “by filing a notice of appeal from that order in the district court, or by filing a motion in the court of appeals if the party has already filed a notice of appeal from the judgment of conviction,” and that the papers “must include a copy of the judgment of conviction.”

Pending sentencing is a different question from pending appeal

The same statute governs two distinct moments, and they are frequently confused.

Between conviction and sentencing, release is governed by § 3143(a). Between sentencing and the end of the appeal, it is governed by § 3143(b). Both start from detention, but the second adds the substantial-question requirement that the first does not have — because before sentencing there is no appeal yet to evaluate.

The practical consequence is that a defendant who was released between a guilty verdict or plea and sentencing should not assume that status carries over. Sentencing is the moment the analysis changes, and it is the moment at which the § 3143(b) motion has to be made. Counsel who waits until after the defendant has been remanded is arguing a harder motion from a worse position.

The offenses where release is effectively unavailable

Section 3143(b)(2) removes the discretion altogether for a defined set of cases. The judicial officer “shall order that a person who has been found guilty of an offense in a case described in subparagraph (A), (B), or (C) of subsection (f)(1) of section 3142 and sentenced to a term of imprisonment, and who has filed an appeal or a petition for a writ of certiorari, be detained.”

The referenced categories in § 3142(f)(1) cover crimes of violence and certain terrorism offenses, offenses carrying life imprisonment or death, and specified serious drug offenses. A defendant convicted in such a case does not get the two-part § 3143(b)(1) analysis at all.

But the door is not fully closed. This is the provision most competing pages omit entirely. Section 3145(c) provides that “[a] person subject to detention pursuant to section 3143(a)(2) or (b)(2), and who meets the conditions of release set forth in section 3143(a)(1) or (b)(1), may be ordered released, under appropriate conditions, by the judicial officer, if it is clearly shown that there are exceptional reasons why such person’s detention would not be appropriate.”

Three things about that sentence are worth noticing. The defendant must still satisfy the ordinary § 3143(b)(1) conditions — the safety valve is additional to them, not a substitute. The showing is “clearly shown,” a demanding standard. And “exceptional reasons” means genuinely out of the ordinary: circumstances that distinguish this defendant from the run of defendants convicted of the same offense.

What release actually looks like if it is granted

Release pending appeal is not release from the judgment. The conviction stands, the sentence stands, and the appeal proceeds.

If granted, release is “in accordance with section 3142(b) or (c),” which means a release order with conditions — typically some combination of supervision by pretrial services, travel restrictions, surrender of a passport, residence conditions, employment requirements, and financial conditions. A violation returns the defendant to custody and may carry separate consequences.

Two further points are commonly misunderstood. First, time spent released pending appeal is not credited against the sentence — the clock on the custodial term effectively pauses, and if the appeal fails the defendant reports to serve it. Second, under § 3143(b)(1)(iv), where release rests on the expectation of a reduced sentence shorter than time served plus the appeal, the statute directs that detention be terminated “at the expiration of the likely reduced sentence” rather than continuing indefinitely.

Applied Insight — Christopher Zoukis, JD, MBA, Managing Director: When release pending appeal is not realistic — which is most of the time — the productive conversation shifts to designation and programming: where the BOP places someone, whether they qualify for RDAP, and how First Step Act time credits accrue. A pending appeal does not pause any of that, and the months spent waiting for a decision are months in which placement and programming decisions are being made. Treating those two tracks as separate is the practical answer to a denied release motion.

If release is denied

A denial is not the end of the appeal — it is a decision about custody during it. The practical steps are:

• Seek review under Rule 9 if there is a basis. A district court order that does not state its reasons, or that applied the wrong standard, is reviewable, and the appeal is to be determined promptly.
• Keep the underlying appeal moving. The single most effective response to a denied release motion is a fast, well-briefed appeal. See how to appeal a federal conviction.
• Ask whether the § 3143(b)(1)(iv) route applies. If the realistic best outcome is a sentence shorter than time served plus the expected appeal, that is a specific statutory argument, and it is frequently overlooked.
• Separate the custody question from the merits question. A denied release motion says nothing about whether the appeal will succeed, and the two are decided by different people on different standards.
• Plan for what a win would mean. If the appeal produces a remand, the custody posture changes again. See what happens after an appeal is granted, and note that a petition for rehearing or a certiorari petition extends the timeline further.

What a § 3143(b) motion has to actually establish

Because the statute is structured as a presumption plus a carve-out, a motion that reads as a plea for leniency will fail regardless of its sympathy. The motion has to march through the elements.

What the motion must establish	What that requires in practice
Not a flight risk, by clear and convincing evidence	Ties to the community, family, employment, compliance history on pretrial release, the absence of foreign travel capacity, and the fact that the defendant appeared throughout the case
Not a danger, by clear and convincing evidence	The nature of the offense, criminal history, conduct on pretrial release, and the specific conditions proposed to mitigate risk
The appeal is not for delay	Identified, briefable issues — and a record that shows they were preserved
A substantial question	The specific issue, why it is close under the governing standard of review, and the circuit authority making it close
Likely to result in one of the four outcomes	An explicit link between the issue and the relief: reversal, new trial, non-custodial sentence, or a sentence shorter than time served plus the appeal
Proposed conditions	A concrete release plan under § 3142(b) or (c), so the court has something to grant rather than a request in the abstract

The fifth row is the one motions most often skip, and it is where they most often fail. Counsel establishes that the appellate issue is genuinely substantial and then stops — leaving the court to work out for itself what relief the issue would produce. If the honest answer is “a remand for resentencing that could well produce a similar term,” the motion does not satisfy the statute, and saying so early is more useful to the client than filing anyway.

The exception is the fourth statutory outcome, which is underused. Where a defendant is serving a relatively short sentence and the appeal is likely to take a year or more, the argument that any reduced sentence would be “less than the total of the time already served plus the expected duration of the appeal process” is a mathematical one rather than a predictive one — and the statute then directs that detention terminate “at the expiration of the likely reduced sentence.”
