Third Circuit Clarifies INA § 1252(b)(9): “Now-or-Never” Requires Unreviewable Questions (Not Merely Irreparable Harms)

1. Introduction

This Third Circuit decision addresses a recurring collision between habeas corpus doctrine and Congress’s immigration “channeling” scheme. Mahmoud Khalil, a lawful permanent resident, was arrested in New York, briefly held in New Jersey, then transferred to Louisiana while removal proceedings proceeded before an immigration judge. Khalil filed a habeas petition (initially in the Southern District of New York) alleging that the government targeted him for pro-Palestinian speech and activism, and that both his detention and removal were unlawful under the First and Fifth Amendments, the Administrative Procedure Act (APA), and Accardi v. Shaughnessy.

Three district-court orders became the focal points on appeal: (1) an order preventing removal; (2) an order requiring his release; and (3) an order intervening in immigration-court proceedings by directing the government to cause the immigration judge to vacate or amend aspects of her removability decision. The government appealed, forcing the Third Circuit to decide two threshold questions:

• Habeas jurisdiction: Did the District of New Jersey have habeas jurisdiction under 28 U.S.C. § 2241 given the rapid transfers and initial filing in New York?
• Subject-matter jurisdiction: Even if habeas jurisdiction existed, did the INA—especially 8 U.S.C. § 1252(b)(9)—strip the district court of authority to adjudicate the claims while removal proceedings were ongoing?

2. Summary of the Opinion

The Third Circuit (per curiam) held:

• Yes—habeas jurisdiction existed. The New York court could transfer under 28 U.S.C. § 1631 because at the time of filing Khalil was in New Jersey (the proper district of confinement). The later amendment naming the Elizabeth Detention Center warden “related back” under Fed. R. Civ. P. 15(c), satisfying the immediate-custodian rule. Post-filing transfer to Louisiana did not defeat jurisdiction under Ex parte Endo and Anariba v. Dir., Hudson Cnty. Corr. Ctr..
• No—subject-matter jurisdiction was lacking. 8 U.S.C. § 1252(b)(9) barred district-court review because Khalil’s claims raised legal/factual questions that could be meaningfully reviewed later through the petition-for-review (PFR) process after a final order of removal.
• Key doctrinal clarification: A “now-or-never” exception to § 1252(b)(9) requires that the questions (legal/factual issues) be unreviewable later on a PFR—not merely that the harms be irreparable or non-redressable.
• Record-development safety valve: The court held that 28 U.S.C. § 2347(b)(3) (Hobbs Act) can permit remand for factfinding when the administrative record is inadequate, and treated this as supporting “meaningful review” on a future PFR.

Disposition: the court vacated and remanded with instructions to dismiss the habeas petition.

3. Analysis

3.1 Precedents Cited (and How They Shaped the Decision)

A. Habeas jurisdiction: geography, custodian, transfer, and relation back

• Braden v. 30th Jud. Cir. Ct. of Ky. and Rumsfeld v. Padilla: The court grounded the “district of confinement” rule in the principle that § 2241(a)’s “within their respective jurisdictions” means jurisdiction over the custodian; for physical custody challenges, that translates into one proper district—where the detainee is confined.
• Martinez-Nieto v. Att'y Gen.: The District of New Jersey could “assume jurisdiction” after transfer where it “would have been able to exercise jurisdiction on the date that the petition was filed.” The Third Circuit endorsed that logic as consistent with § 1631’s temporal requirement.
• 28 U.S.C. § 1631 transfer line: The opinion treated the transfer question as text-driven, reinforced by Hoffman v. Blaski (interpreting “where it might have been brought” to refer to the time of original filing) and D'Jamoos ex rel. Est. of Weingeroff v. Pilatus Aircraft Ltd. (describing § 1404(a) as comparable to § 1631). The Second Circuit’s Öztürk v. Hyde, 136 F.4th 382 further supported that § 1631 “remedies procedural defect” without creating “substantive authority.”
• Boechler, P.C. v. Comm'r: Used for the court’s obligation to address jurisdictional issues sua sponte, even if not argued below.
• Hassine v. Zimmerman, Parrott v. Gov't of V.I., and Santana v. United States: These cases framed habeas as generally “civil in nature” for jurisdictional purposes, enabling § 1631’s “civil action” language to encompass habeas petitions.
• Robinson v. Johnson: Cited to confirm that § 1631 transfers are available in habeas practice (e.g., for second-or-successive petitions), reinforcing doctrinal comfort with transfer mechanisms.
• Ex parte Endo, reaffirmed by Rumsfeld v. Padilla, and applied through Third Circuit precedent Ex parte Catanzaro and Anariba v. Dir., Hudson Cnty. Corr. Ctr.: Together, these prevented the government from defeating jurisdiction by moving the detainee after a proper filing; jurisdiction “does not lose” by transfer out of district.
• Immediate custodian rule: The opinion acknowledged the default rule from Rumsfeld v. Padilla and explained the district court’s reliance on the “unknown custodian exception” described in Demjanjuk v. Meese, but ultimately avoided that issue because amendment and relation back cured the defect.
• Relation back doctrine in habeas: Using Mayle v. Felix, the court treated the habeas petition as the “pleading” for Fed. R. Civ. P. 15(c) purposes, allowing the later-added New Jersey warden to relate back. The superseding-amended-pleading principle came from Garrett v. Wexford Health and the habeas analogue Washer v. Bullitt Cnty..
• Royal Canin U.S.A., Inc. v. Wullschleger: The government argued amendments can destroy jurisdiction. The Third Circuit distinguished Royal Canin as addressing subject-matter jurisdiction in ordinary civil cases, not habeas “jurisdiction” concepts like immediate custodian or district-of-confinement (which Padilla itself treats as different from subject-matter jurisdiction).
• Darfur v. U.S. Parole Comm'n: Cited to support a modern view that immediate custodian implicates personal jurisdiction and district-of-confinement resembles venue—not subject-matter jurisdiction.

B. INA channeling: the scope and meaning of § 1252(b)(9)

• Tazu v. Att'y Gen.: Reinforced that § 1252(b)(9) channels “legal questions” bound up with actions taken to remove an alien.
• E.O.H.C. v. Sec'y, U.S. Dep't of Homeland Sec.: This was the central Third Circuit precedent on the “now-or-never” concept. The majority interpreted E.O.H.C. as leaving open whether now-or-never turns on (a) inability to remedy harms later or (b) inability to meaningfully review questions later—then resolved that ambiguity in favor of “questions.”
• Reno v. AADC: Provided the “zipper clause” metaphor and the channeling purpose: consolidate review and prevent “piecemeal litigation.”
• Carlson v. Landon: Used to show detention is “necessarily” part of the removal process, supporting that detention can be an “action taken” to remove within § 1252(b)(9).
• Issue-preclusion caution: Paulo v. Holder was cited to show how early district-court merits rulings can preclude later immigration adjudication—exactly the “two bites” outcome § 1252(b)(9) is designed to avert.
• Massieu v. Reno: Supported that challenges contingent on the validity of removal orders belong in the PFR process.
• Abbott Lab'ys v. Gardner and Jie Fang v. Dir. U.S. Immigr. & Customs Enf't: Supplied ripeness principles; challenges to a charge not actually used as a ground of removal may be unripe.
• Lewis v. Att'y Gen.: Used for substance-over-label in pleading; a “punitive detention” claim cannot evade § 1252(b)(9) if it is substantively a challenge to removal initiation/basis.

C. Final-order debate and the shadow of Jennings/Chezazeh

• Chehazeh v. Att'y Gen.: Khalil invoked Chehazeh to argue § 1252(b)(9) applies only once the Board issues a final order. The majority held that part of Chehazeh was abrogated by the fractured Supreme Court in Jennings v. Rodriguez.
• Jennings v. Rodriguez and the Marks v. United States framework (via Lebanon Farms Disposal, Inc. v. Cnty. of Lebanon): The majority treated the Jennings plurality’s view of § 1252(b)(9) as the “narrower” controlling position under Marks, concluding § 1252(b)(9) can apply to at least some pre-final-order challenges.

D. Administrative record adequacy and the Hobbs Act “escape hatch”

• 8 U.S.C. § 1252(b)(4)(A): Limitation to the “administrative record” in PFR review raised the concern that constitutional/pattern-and-practice claims might be unreviewable.
• McNary v. Haitian Refugee Ctr., Inc.: Recognized that some systems are ill-suited to develop broad factual challenges; used by the court to acknowledge record-development tension, but not to expand district-court jurisdiction here.
• 28 U.S.C. § 2347(b)(3) and Gallo-Alvarez v. Ashcroft: The court held § 2347(b)(3) remains available (notwithstanding Congress’s express bar on § 2347(c) supplementation in 8 U.S.C. § 1252(a)(1)), relying on negative-implication reasoning associated with Russello v. United States.
• Accardi v. Shaughnessy: Although not reached on the merits, the case framed part of Khalil’s theory as an agency “must follow its own rules” claim, which the court deemed reviewable later via PFR.

3.2 Legal Reasoning

A. Step One: Habeas jurisdiction existed (procedurally meticulous, but ultimately academic)

The court’s habeas analysis is notable for how it neutralizes two common government defenses in fast-moving immigration arrests: (1) “wrong district” and (2) “wrong respondent.” The court reasoned that § 1631 prevents a jurisdictional whipsaw where the petitioner’s location changes overnight and ICE databases lag. By treating the petition “as if filed” in New Jersey on the original filing date, the court preserved the correct district-of-confinement anchor. It then used Rule 15(c) relation back to cure the immediate-custodian defect—an approach that implicitly credits practical realities of detention transfers while still honoring Padilla’s anti-forum-shopping function.

B. Step Two: But § 1252(b)(9) stripped subject-matter jurisdiction

Having found habeas jurisdiction, the court separated “habeas jurisdiction” (district-of-confinement and custodian rules) from subject-matter jurisdiction (Congress’s power to channel review). The controlling move is the court’s interpretation of “arising from” in § 1252(b)(9), and the resulting definition of “now-or-never.”

The court rooted this in (1) statutory text (“Judicial review of all questions of law and fact”), (2) title (“Consolidation of questions for judicial review”), and (3) statutory purpose (the “zipper clause” meant to prevent “piecemeal litigation” and ensure “one bite at the apple”). The opinion’s functional concern is that allowing district-court habeas review of questions later reviewable on PFR would let litigants front-load constitutional and statutory attacks, potentially triggering issue preclusion in later removal review (illustrated by Paulo v. Holder), undermining Congress’s channeling scheme.

C. Application to Khalil’s claims: “inextricably linked” to removal, therefore channeled

The court characterized Khalil’s First Amendment retaliation, due process, vagueness-as-applied, APA, and Accardi theories as attacks on the government’s basis for removal and detention. Because those questions can be resolved in a PFR after a final order of removal, § 1252(b)(9) applies—even though the district court found some likelihood of success on the foreign-policy charge and even though the district court viewed its injunction as necessary to prevent ongoing constitutional injury.

The court also treated Khalil’s “punitive detention” allegation as substantively derivative of his removal challenge. By invoking Lewis v. Att'y Gen., it refused to allow pleading labels to evade channeling: if the detention claim depends on proving the illegality of commencing/removing on the charged grounds, it belongs in the PFR pathway.

D. Meaningful future review: the Hobbs Act remand and other tools

A major practical objection to channeling is record development. Khalil argued immigration proceedings are structurally ill-suited to develop evidence about retaliatory motive, discriminatory enforcement, or policy-level targeting—especially where the immigration judge denied discovery into the Secretary of State’s foreign-policy determination (relying on Matter of Ruiz-Massieu, 22 I. & N. Dec. 833 (BIA 1999)).

The Third Circuit responded by emphasizing that aliens can build records through testimony and exhibits (which Khalil had done) and, critically, that courts of appeals can supplement factfinding via 28 U.S.C. § 2347(b)(3) (Hobbs Act), as recognized in Gallo-Alvarez v. Ashcroft. This—together with possible tools like a special master or Fed. R. App. P. 48 (noted in the government’s post-argument letter)—allowed the court to conclude that “meaningful review” remains available in the PFR process.

E. The dissent’s competing vision (Freeman, J.)

Judge Freeman agreed on habeas jurisdiction but dissented on subject-matter jurisdiction. She read Chehazeh v. Att'y Gen. as still controlling, and argued § 1252(b)(9) activates only with a final order of removal. She also interpreted E.O.H.C. v. Sec'y U.S. Dep't of Homeland Sec. as making “now-or-never” turn on redressability of harms—particularly irreparable First Amendment injury—rather than the later reviewability of questions. The dissent further doubted that meaningful review would occur in practice given immigration-judge limitations on constitutional adjudication and factual development, and warned that if a final order never issues, the PFR route may never open.

3.3 Impact

A. A tighter “now-or-never” escape hatch under § 1252(b)(9)

The opinion’s most consequential doctrinal move is its reframing of the now-or-never inquiry. By requiring that the questions be unreviewable later—not merely that the harms be irreparable—the Third Circuit materially narrows the set of immigration-related habeas cases that can proceed in district court while removal proceedings are pending. This is especially significant for claims alleging retaliation, viewpoint discrimination, selective enforcement, or unconstitutional vagueness in the decision to initiate removal, because those typically can be “reviewed” later even if interim detention imposes serious, time-sensitive harms.

B. Strong reinforcement of the INA’s channeling design

The opinion is an explicit defense of the INA’s “one-bite” architecture: immigration judges and the BIA first; then one petition for review in a court of appeals. District courts, even when they have § 2241 custody jurisdiction, are positioned as largely sidelined where the claims are intertwined with removability and the decision to detain/remove.

C. Practical shift to courts of appeals for factual development disputes

By holding 28 U.S.C. § 2347(b)(3) is available in immigration PFRs, the court supplies an important counterweight to concerns about record inadequacy. Future litigants in the Third Circuit may increasingly brief § 2347(b)(3) as the mechanism for developing evidence of motive/policy where immigration courts limit discovery. The decision also invites government litigating positions to matter: the court relied (in part) on the government’s representations that record supplementation mechanisms are available.

D. Litigation strategy and forum consequences

• For detainees: Expect more pressure to frame challenges as truly “collateral” (e.g., conditions-of-confinement like inadequate medical care) rather than as attacks on the basis for removability/detention.
• For the government: The decision reduces exposure to district-court injunctions that halt removal proceedings midstream and curbs district-court orders directing outcomes in immigration court.
• For district courts: Even where § 2241 custody jurisdiction is secure (via transfer and relation back), the merits may remain unreachable due to § 1252(b)(9).

4. Complex Concepts Simplified

• Habeas “jurisdiction” vs subject-matter jurisdiction: A district court can have the power to issue a writ over a custodian (habeas jurisdiction in the § 2241 sense) but still be barred from hearing the case because Congress assigned that type of dispute to a different review path (here, INA channeling to a PFR).
• District-of-confinement rule: For physical-custody challenges, the proper venue/district is where the person is held at filing—typically only that district can entertain the § 2241 petition.
• Immediate custodian rule: The proper respondent is usually the person with day-to-day control (the warden), not a cabinet official. Naming the wrong respondent can defeat habeas jurisdiction unless cured.
• 28 U.S.C. § 1631 transfer: If a case is filed in the wrong court, § 1631 permits transfer to the correct court “in the interest of justice,” and the case proceeds as though filed there on the original date.
• Relation back (Rule 15(c)): If an amended pleading adds the proper party and the rule’s conditions are met, the amendment is treated as if it occurred on the original filing date—critical where timing determines jurisdiction.
• 8 U.S.C. § 1252(b)(9) (“zipper clause”): A statutory rule that consolidates (“zips”) judicial review of questions arising from removal actions into one petition for review in a court of appeals after a final removal order.
• Petition for review (PFR): The exclusive vehicle—under the INA’s channeling scheme—for most legal challenges tied to a final order of removal, filed in the appropriate court of appeals.
• Hobbs Act remand (28 U.S.C. § 2347(b)(3)): A procedure allowing a court of appeals, in specified circumstances, to remand for factfinding when the agency record is inadequate and genuine issues of material fact exist.

5. Conclusion

The Third Circuit’s decision delivers a two-part message. First, it makes clear that rapid ICE transfers and initial misfilings need not defeat habeas jurisdiction where § 1631 transfer and Rule 15(c) relation back align the petition with the district-of-confinement and immediate-custodian requirements. Second—and more importantly—it tightens the INA channeling regime by holding that § 1252(b)(9)’s “now-or-never” pathway depends on whether the legal/factual questions are unreviewable later on a PFR, not whether interim constitutional harms are irreparable.

In practical effect, the opinion substantially limits district-court intervention in ongoing removal proceedings even when claims are framed in constitutional terms, steering litigants toward the administrative process and eventual court-of-appeals review, with § 2347(b)(3) positioned as a key mechanism to address record-development concerns.
