Decision: Jennings v. Rodriguez, 583 U.S. 281 (2018).

Jennings v. Rodriguez, 583 U.S. 281 (2018), rejected a statutory rule requiring bond hearings every six months with the government carrying a clear-and-convincing burden. Its reasoning differed across three detention provisions: Mandatory detention under section 1225(b), mandatory detention under section 1226(c), and discretionary detention with bond authority under section 1226(a). The Court reversed the statutory ruling but sent the actual constitutional claims and class-procedure questions back for further consideration. Jennings, 583 U.S. at 296–306, 312–314.

A class challenged prolonged detention without hearings

Alejandro Rodriguez, a lawful permanent resident, remained detained while contesting removal after criminal convictions. His custody challenge became a class action covering people detained beyond six months without an individualized hearing justifying continued confinement. The district court grouped the class by detention statute. The Ninth Circuit ultimately sustained three relevant subclasses and a recurring-hearing remedy; the section 1231 subclass was no longer part of that ruling. Jennings, 583 U.S. at 289–292.

The Ninth Circuit used constitutional avoidance to read sections 1225(b) and 1226(c) as permitting only six months of detention under those provisions, followed by detention under section 1226(a). It then imposed hearings every six months and a government clear-and-convincing burden. The Supreme Court held that avoiding a serious constitutional question permits choosing a plausible reading, not rewriting statutory text to produce the preferred protection. Jennings, 583 U.S. at 292, 296–298.

The statutes did not contain the proposed limit

Section 1225(b): Detention through the relevant proceedings. The Court read the commands to detain applicants for further asylum consideration or removal proceedings as continuing through those proceedings, rather than ending when a hearing began or after six months. The statute also expressly allowed temporary parole for urgent humanitarian reasons or significant public benefit. The majority treated that specified exception as another reason not to infer the different bond regime ordered below. Jennings, 583 U.S. at 297–303.

Why Zadvydas did not supply the missing rule. That decision interpreted section 1231(a)(6), governing detention beyond the removal period, and its permissive language allowing detention. Here, the provisions mandated detention through identified proceedings and included express release rules. The Court distinguished those textual features rather than announcing that the passage of time could never raise a constitutional problem. Jennings, 583 U.S. at 298–301.

Section 1226(c): A narrow express release exception. For people actually within this mandatory-detention category, the Court emphasized the command to take custody and the provision allowing release only for specified witness-protection purposes. It rejected the proposed automatic transfer into section 1226(a) after six months. Whether a particular person fits the statutory category is distinct from whether its detention language contains a recurring-hearing entitlement. The opinion’s footnote 1 identifies a Joseph hearing as a way to challenge coverage of section 1226(c), while stating that these respondents’ entitlement to such hearings was not before the Court. That classification question is different from the rejected periodic-hearing rule. Jennings, 583 U.S. at 289 n.1, 303–306.

Section 1226(a) had its own express mechanism

Section 1226(a) was not the same as the two mandatory branches. It allowed release on bond or conditional parole, and the Court noted regulations providing an initial bond hearing. What it rejected was reading into that text additional hearings every six months, a clear-and-convincing burden on the government, and a statutory command specifically to consider the time already detained. The holding therefore did not erase the ordinary bond mechanism while rejecting the added periodic procedures. Jennings, 583 U.S. at 306.

That distinction changes the question a custody record must answer. A person seeking ordinary bond consideration under section 1226(a), a person contesting mandatory-category coverage, and a person raising a constitutional objection to prolonged custody are making different claims. The statute and the prior custody decision—not the detention facility or a six-month anniversary alone—identify which problem requires analysis.

Constitutional issues remained open

The Court did not decide the class’s constitutional arguments because the Ninth Circuit had resolved the case by statutory interpretation. It remanded those arguments, while directing the lower court first to reexamine classwide relief under section 1252(f)(1), Rule 23(b)(2) and the potentially differing due-process circumstances of class members. The reserved issues were concrete: Whether the Constitution required additional process and whether the requested remedy could properly proceed for the class. Jennings, 583 U.S. at 312–314.

The separate opinions also matter. Justice Thomas, joined in relevant part by Justice Gorsuch, disputed jurisdiction while agreeing with the statutory result. Justice Breyer, joined by Justices Ginsburg and Sotomayor, would have read the provisions in light of serious constitutional concerns to require bail hearings presumptively after six months of confinement; he did not adopt every special procedure the Ninth Circuit had imposed. Alito’s jurisdiction discussion in Part II did not command the same majority as the statutory holdings. Jennings, 583 U.S. at 284–285 n.†, 314–326, 326–356.

Later decisions illustrate why the statutory and constitutional tracks must stay separate. In Johnson v. Arteaga-Martinez, No. 19-896 (U.S. June 13, 2022), the Court rejected a similar six-month hearing-and-burden requirement under section 1231(a)(6), while leaving actual constitutional and alternative Zadvydas claims for lower-court consideration. Our Diouf II analysis addresses that separate post-order framework. Arteaga-Martinez, opinion, pages 6–10.

More recently, Padilla v. U.S. Immigration and Customs Enforcement, No. 24-2801 (9th Cir. Sept. 21, 2026), affirmed denial of dismissal on two certified issues: Jurisdiction and whether Thuraissigiam foreclosed the class’s due-process claim. That published interlocutory decision concerned a class including people apprehended beyond the threshold of initial entry. It did not decide what hearing timing or procedures the Constitution ultimately required; those merits questions lay outside the certified appeal. It therefore supports careful separation of a viable constitutional claim from an already established hearing remedy. Padilla, opinion, pages 7–8, 14–15, 27–38, 45–46.

Key takeaways

• Identify which detention provision applies and the procedural event tying custody to it. Do not merge the three branches simply because all involve removal.
• For section 1226(a), distinguish an initial bond process from the recurring hearings and burden rule rejected as statutory requirements.
• For a constitutional claim, identify the actual duration, prior process and requested remedy; preserve its theory separately from the rejected statutory construction.
• Read later rulings for their posture. Allowing a due-process claim to proceed is not the same as ordering release or a hearing on a fixed timetable.
