Introduction

When an immigration case reaches a final order of removal, the legal theory of detention changes—often abruptly. The government is no longer detaining someone “pending a decision on whether the alien is to be removed.” Instead, detention is generally governed by INA § 241, 8 U.S.C. § 1231, a statutory scheme built around a defined “removal period” and a narrower set of post‑order detention authorities. See 8 U.S.C. § 1231(a)(1)–(6).

That transition matters because many of the familiar pre‑order tools—especially routine Immigration Judge bond jurisdiction—drop away. Post‑order detention disputes are therefore less about bond statutes and more about (1) when the removal period starts, (2) whether continued detention is authorized after the removal period, and (3) whether removal is realistically foreseeable in the time horizons that due process (as filtered through Supreme Court statutory construction) will tolerate.

This article provides a reader‑facing roadmap. It starts with the Supreme Court’s controlling architecture, then surveys the principal circuit approaches to post‑order detention under § 1231, including the recurrent “what statute applies?” fights in stay‑of‑removal and reinstatement/withholding‑only cases.

Martinez, 543 U.S. 371 (2005)); (3) detention issues in protection postures such as deferral of removal (Issues for Aliens Who Have Been Granted Deferral of Removal; (4) reinstatement and withholding‑only procedural posture (Reinstatement of Removal; Relationship Between Order of Removal and Order of Withholding of Removal); and (5) general detention litigation orientation (Immigration Detention Defense).

The Statutory Backbone: INA § 241 and the 90‑Day Removal Period

A. The removal period is the center of gravity

Under INA § 241(a)(1), 8 U.S.C. § 1231(a)(1), DHS ordinarily has 90 days—the “removal period”—to execute the final order. During that removal period, detention is generally mandatory. 8 U.S.C. § 1231(a)(2).

B. The start date is not always “the day the BIA affirmed”

Congress defined when the removal period begins. 8 U.S.C. § 1231(a)(1)(B) sets three triggers; the relevant one often is the date a court enters a final order after judicial review if a stay of removal is in place. See 8 U.S.C. § 1231(a)(1)(B)(ii).

That statutory start‑date rule is the engine behind a major set of disputes: when a noncitizen has a judicial stay pending a petition for review, many circuits treat detention as pre‑order detention under 8 U.S.C. § 1226, not post‑order detention under § 1231—because the “removal period” has not yet begun. See, e.g., Hechavarria v. Sessions, 891 F.3d 49 (2d Cir. 2018). (Related MyAttorneyUSA background: Immigration Detention Defense).

C. Detention beyond the removal period: § 1231(a)(6)

After the removal period, DHS can continue to detain certain categories under 8 U.S.C. § 1231(a)(6) (including many inadmissible and criminal grounds cases), or release under supervision. 8 U.S.C. § 1231(a)(3), (a)(6).

This “beyond the removal period” authority is where the Supreme Court’s limiting constructions come in.

The Supreme Court Overview: Zadvydas, Clark, Guzman Chavez, and the Post‑Arteaga‑Martinez World

A. Zadvydas: no “potentially permanent” post‑order detention

The foundational case is Zadvydas v. Davis, 533 U.S. 678 (2001). Interpreting 8 U.S.C. § 1231(a)(6) to avoid serious constitutional concerns, the Court held that post‑order detention is limited to a period reasonably necessary to secure removal. The Court identified six months as a presumptively reasonable time. After six months, once a detainee provides “good reason to believe” there is no significant likelihood of removal in the reasonably foreseeable future, the government must rebut that showing. Id. at 701. (MyAttorneyUSA PDF library: Zadvydas v. Davis, 533 U.S. 678 (2001))

Zadvydas is often summarized as a “six‑month rule,” but its operative test is foreseeability of removal and evidence. For a real‑world illustration of how Zadvydas constraints interact with country travel‑document delays, see DHS/DOS Imposed § 243(d) Visa Sanctions Against Burma and Laos.

B. Clark v. Martinez: the same statutory reading applies across categories

The Court extended Zadvydas’s interpretation of § 1231(a)(6) to inadmissible (arriving) noncitizens in Clark v. Martinez, 543 U.S. 371 (2005). The statutory phrase cannot mean “six months max absent foreseeability” for one group and “indefinite detention” for another when the operative provision is the same. Id. at 378–86. (MyAttorneyUSA PDF library: Clark v. Martinez, 543 U.S. 371 (2005)).

C. Johnson v. Guzman Chavez: withholding‑only (reinstatement) detentions sit in § 1231

A separate but recurring question is which detention statute applies to people with reinstated removal orders placed into withholding‑only proceedings. The Supreme Court held that detention in that posture is governed by 8 U.S.C. § 1231, not 8 U.S.C. § 1226. Johnson v. Guzman Chavez, 594 U.S. 523 (2021).

For reader‑facing orientation on withholding‑only posture and how federal courts describe it as narrow in scope, see BIA Bars Immigration Judges from Terminating Withholding‑Only Proceedings(discussing Johnson v. Guzman Chavez, 594 U.S. 523 (2021) in the withholding‑only context), and also Reinstatement of Removal.

Guzman Chavez matters because it constrains a common defense argument that withholding‑only proceedings “reopen” the question whether the person “is to be removed” and therefore place the person back into § 1226. The Court rejected that framing. Id. at 534–45.

D. Johnson v. Arteaga‑Martinez and Garland v. Aleman Gonzalez: no automatic bond hearing “read‑in” and limits on classwide injunctions

In Johnson v. Arteaga‑Martinez, 596 U.S. 573 (2022), the Court rejected the statutory claim that § 1231(a)(6) itself requires a bond hearing after six months with a particular burden allocation. In parallel, Garland v. Aleman Gonzalez, 596 U.S. 543 (2022) curtailed certain classwide injunctive relief against the operation of the detention statutes.

Together, these decisions reshaped litigation strategy: Zadvydas/Clark remain the core post‑order detention limitations, but efforts to convert § 1231(a)(6) into a generalized bond‑hearing regime via statutory interpretation face steep headwinds. (For a general discussion of how Aleman Gonzalez is cited in post‑2022 federal litigation posture, see Developments in Deferred Action for SIJ)

E. DHS v. D.V.D.: § 1231 removal mechanics can generate detention pressure even apart from bond doctrine

While not a detention‑duration case, Supreme Court emergency‑docket disputes about removal logistics can still matter because they affect the government’s asserted ability to execute removal (including third‑country removal pathways). See Dep’t of Homeland Sec. v. D.V.D., No. 24A1153, slip op. (U.S. June 23, 2025) (addressing constraints on “third‑country removal” under 8 U.S.C. § 1231(b)).

The Core Post‑Order Question: Is Removal “Significantly Likely” in the Reasonably Foreseeable Future?

Post‑order detention litigation tends to be less about abstract “bond rights” and more about evidence and timeline:

1. Has the removal period begun? (statute selection)
2. How long post‑order detention has occurred? (Zadvydas clock, tolling arguments)
3. What is the government’s removal plan and what evidence supports it? (travel documents, country conditions, repatriation agreements, diplomatic communications)
4. Is the noncitizen obstructing removal? (which can affect the statutory calculus)
5. What custody reviews has DHS conducted under its regulations? (often under 8 C.F.R. §§ 241.4, 241.13, and supervision rules such as 8 C.F.R. § 241.5)

Zadvydas provides the legal test; the record provides the outcome. For background on detention posture in protection contexts (where removal may be complicated by CAT deferral or withholding), see Issues for Aliens Who Have Been Granted Deferral of Removal.

Circuit Overview: The Major Buckets of Post‑Final‑Order Detention Litigation

A “most circuits” overview is easiest if organized by the disputes that recur nationwide.

A. “Which statute applies?” — stays of removal and the § 1226 vs. § 1231 boundary

The recurring scenario: A final administrative order exists, but the person has a petition for review pending and a judicial stay in place.

Many circuits treat that situation as § 1226 detention, reasoning that the removal period does not begin while a court‑ordered stay blocks execution. A frequently cited Second Circuit example is Hechavarria v. Sessions, 891 F.3d 49 (2d Cir. 2018) (holding detention was under 8 U.S.C. § 1226(c), not § 1231, because a stay meant the removal period had not begun).

The Ninth Circuit has long addressed similar statute‑selection disputes in stay scenarios. See, e.g., Prieto‑Romero v. Clark, 534 F.3d 1053 (9th Cir. 2008) (placing certain stay‑pending‑review detention within § 1226(a)).

The practical consequence is significant: if detention is governed by § 1226, the litigation posture looks like pre‑order prolonged detention (with the circuit’s § 1226 due process doctrine). If detention is under § 1231, the posture shifts toward Zadvydas/Clark foreseeability analysis plus DHS custody review regulations. (For a broader detention‑litigation orientation and terminology, see Immigration Detention Defense)

B. Reinstatement + withholding‑only: § 1231 governs, but “prolonged” questions remain

After Johnson v. Guzman Chavez, most withholding‑only detention disputes are doctrinally anchored in § 1231, even if removal to the designated country is barred by withholding. 594 U.S. 523 (2021).

What remains litigated is not the statute selection but the Zadvydas‑type question: can DHS show a realistic removal pathway (including potentially to a third country) within a reasonably foreseeable time? For background on how withholding presupposes an underlying order of removal (and thus why § 241 concepts keep resurfacing), see Relationship Between Order of Removal and Order of Withholding of Removal.

C. The Zadvydas clock, tolling, and “who has the burden” in practice

Although Zadvydas gives a general six‑month presumption, many circuits have emphasized that six months is a threshold presumption, not an automatic release rule; and the detainee must initially produce good reason to doubt foreseeability; then the government must rebut.

Some circuits have also addressed when the six‑month period is tolled due to detainee‑caused delays. The Eleventh Circuit is frequently cited for tolling‑oriented interpretations. See Akinwale v. Ashcroft, 287 F.3d 1050 (11th Cir. 2002).

Circuit Survey: Representative Post‑Order Detention Precedents by Circuit

This section summarizes commonly cited controlling or anchor precedents used in post‑order detention briefing.

First Circuit

The First Circuit’s post‑order detention cases generally track Zadvydas’s foreseeability framework and emphasize individualized, record‑based analysis.

Second Circuit

The Second Circuit is a major venue for statute‑selection disputes in stay‑pending‑review cases. Hechavarria v. Sessions, 891 F.3d 49 (2d Cir. 2018).

Third Circuit

The Third Circuit has long been active in detention litigation. See, e.g., Leslie v. Att’y Gen. of U.S., 678 F.3d 265 (3d Cir. 2012).

Fourth Circuit

After Johnson v. Guzman Chavez, withholding‑only detention disputes are largely channeled through § 1231.

Fifth Circuit

The Fifth Circuit has applied Zadvydas principles in post‑order detention cases. Tran v. Mukasey, 515 F.3d 478 (5th Cir. 2008).

Sixth Circuit

The Sixth Circuit has been an important source of post‑order detention precedent. Rosales‑Garcia v. Holland, 322 F.3d 386 (6th Cir. 2003).

Seventh Circuit

Seventh Circuit cases generally follow Zadvydas’s statutory construction and require a record‑based showing regarding foreseeability of removal.

Eighth Circuit

The Eighth Circuit has applied Zadvydas’s “significant likelihood of removal” test. Borrero v. Aljets, 325 F.3d 1003 (8th Cir. 2003).

Ninth Circuit

The Ninth Circuit’s post‑order detention landscape is shaped by stay‑pending‑review statute selection disputes. Prieto‑Romero v. Clark, 534 F.3d 1053 (9th Cir. 2008).

Tenth Circuit

Tenth Circuit post‑order detention cases typically apply the Zadvydas foreseeability test in a fact‑specific way.

Eleventh Circuit

The Eleventh Circuit is frequently cited for how it conceptualizes the six‑month period and tolling. Akinwale v. Ashcroft, 287 F.3d 1050 (11th Cir. 2002).

D.C. Circuit

D.C. Circuit issues often intersect with broader administrative‑law or federal detention questions.

Practical Litigation Framing: What Wins (and What Doesn’t) After the Final Order

A. Don’t litigate “bond” when the statute is “foreseeability”

After a final order, the most direct claim usually: identifies the detention statute (§ 1231 or § 1226 if a stay delays the removal period), applies Zadvydas/Clark (for § 1231) or the circuit’s § 1226 due process doctrine (if detention is pre‑order due to a stay), and builds a record around removal logistics. (For a general detention practice hub that helps situate these pathways, see Immigration Detention Defense)

B. Evidence that matters

Courts respond to tangible record facts: travel documents; whether the receiving country has accepted repatriation in comparable cases; scheduling; consular communications; whether third‑country removal is an actual plan or a theoretical possibility.

C. Beware of “self‑inflicted delay” arguments

The government frequently argues that prolonged detention is attributable to the noncitizen’s actions. Courts vary in receptivity, but tolling and delay‑attribution arguments are routine. See Akinwale, 287 F.3d 1050.

D. Administrative custody review is not a substitute for a judicial foreseeability determination

Post‑order custody reviews under DHS regulations are often part of the factual record, but the Zadvydas inquiry ultimately asks whether continued detention is authorized in light of the foreseeability of removal.

Bottom Line

Post‑final‑order detention is not a continuation of pre‑order bond litigation by other means. It is a different regime governed by INA § 241, 8 U.S.C. § 1231, and dominated by the Supreme Court’s limiting constructions in Zadvydas v. Davis, 533 U.S. 678 (2001), and Clark v. Martinez, 543 U.S. 371 (2005)—with statute‑selection rules complicated by stays (Hechavarria v. Sessions, 891 F.3d 49 (2d Cir. 2018); Prieto‑Romero v. Clark, 534 F.3d 1053 (9th Cir. 2008)) and by the Supreme Court’s placement of withholding‑only detention in § 1231 (Johnson v. Guzman Chavez, 594 U.S. 523 (2021)).

In practice, the decisive question is usually simple to state and hard to prove: Is removal significantly likely in the reasonably foreseeable future? After six months, courts expect the government to answer that question with real evidence—or to justify why the statutory framework still permits continued detention.
