Tenth Circuit: 8 U.S.C. § 1225(b)(2)(A) Mandatory Detention Is Border-Limited; Interior Unadmitted Noncitizens Fall Under § 1226(a) and Are Bond-Eligible

Precedents Cited

The opinion is notable for integrating Supreme Court interpretive doctrine, immigration-specific detention jurisprudence, and post-2024 administrative-law signals about “longstanding practice,” while also situating itself within an active circuit split (Second/Sixth/Eleventh vs. Fifth/Eighth).

1) Statutory interpretation methodology

• Star Athletica, LLC v. Varsity Brands, Inc. and Est. of Cowart v. Nicklos Drilling Co.: invoked for the baseline commitment to enforce “clear meaning” as written.
• Robinson v. Shell Oil Co.: cited for the tri-part interpretive frame—text, immediate context, and broader statutory context.
• Duncan v. Walker: grounds the court’s “begin with the language of the statute” approach.
• Taniguchi v. Kan Pac. Saipan, Ltd.: supports using ordinary meaning when a term is undefined.
• Van Buren v. United States and Tanzin v. Tanvir (with reinforcement from Feliciano v. Dep't of Transp.): used to insist that when Congress supplies a definition, courts must follow it even if it diverges from ordinary usage—central to rejecting the government’s “college applicant” analogy.
• Badgerow v. Walters: for the negative-implication principle: inclusion in one provision and omission in another tends to be deliberate.
• Parrish v. United States and NLRB v. SW Gen., Inc.: caution that negative implications are context-dependent; the court deploys these to handle dueling “omissions” arguments about § 1225’s border-centric language.
• Advoc. Health Care Network v. Stapleton, Williams v. Taylor, and DePierre v. United States: anchor the anti-surplusage and different-words-different-meaning canons used to give independent effect to “seeking admission.”
• Marx v. Gen. Revenue Corp., Rimini St., Inc. v. Oracle USA, Inc., Kirtsaeng v. John Wiley & Sons, Inc., and Stanley v. City of Sanford: acknowledge redundancy can sometimes be tolerated, but place the burden on the government to justify why redundancy is the “more natural” reading here.
• Whitman v. Am. Trucking Ass'ns: undergirds the court’s skepticism that one word (“deemed”) could serve as a “mousehole” authorizing an “elephant” (mass bondless detention).
• TC Heartland LLC v. Kraft Foods Group Brands LLC: decisive authority against the “deemed is not definitional” argument; the Supreme Court treated a “deemed” clause as definitional in the venue statute.
• Pereira v. Sessions: cited to illustrate that Congress uses multiple signals for definitional language, not only “means” or “defined.”
• Atl. Sounding Co. v. Townsend and Tank v. Chronister: reinforce the court’s refusal to “attribute words to Congress that it has not written,” rejecting the leap from “deemed an applicant” to “deemed seeking admission.”
• Henson v. Santander Consumer USA Inc. and Dodd v. United States: restrain purposivism: courts presume Congress “means what it says,” not that text must be bent to match a broad policy story.
• Mohamad v. Palestinian Auth.: encapsulates the conclusion that purpose cannot overcome plain text.

2) Longstanding governmental practice and interpretive weight after Loper Bright

• Loper Bright Enters. v. Raimondo: used to treat “longstanding practice of the government” and roughly contemporaneous, consistent executive interpretation as meaningful context. The court frames the 1997 regulation (62 Fed. Reg. 10312, 10323) and decades of practice as probative against the government’s 2025 reversal.
• Learning Res., Inc. v. Trump: supports the proposition that consistent presidential practice is “strong evidence” about statutory meaning; the court uses this to discount the “bureaucratic inertia” rejoinder.
• Biden v. Texas: immigration-specific precedent emphasizing that consistent cross-administration practice since IIRIRA is evidence against a sudden, contrary construction.

3) Immigration structure and detention authorities

• Kansas v. Garcia: cited for the INA’s foundational role.
• Kawashima v. Holder and Judulang v. Holder: situate IIRIRA’s shift from entry-based exclusion/deportation to admissibility/deportability and unified removal proceedings.
• Jennings v. Rodriguez: highly influential dicta: § 1225 governs those at the “Nation’s borders and ports of entry,” while § 1226 governs those “inside the United States.” The Tenth Circuit treats this as strongly persuasive, explaining it is “bound by Supreme Court dicta almost as firmly as” holdings (citing its own precedent).
• Nielsen v. Preap: critical structural point—§ 1226(c) is not an independent detention regime but a limit on § 1226(a). This blocks the government’s attempt to preserve § 1226(c)’s inadmissibility references under its reading.
• Monsalvo v. Bondi, Haig v. Agee, Lamar, Archer & Cofrin, LLP v. Appling, and Lorillard v. Pons: used to read the Laken Riley Act (2025) against the backdrop of longstanding interpretation; Congress’s choice to add a new § 1226(c) exception is treated as ratification of the border/interior divide rather than expansion of § 1225(b)(2)(A).

4) “Admission” versus post-entry lawful status

• Sanchez v. Mayorkas: central to the court’s point that “lawful status” and “admission” are distinct; one can become lawful without retroactively becoming “admitted.”
• Medina-Rosales v. Holder (with Negrete-Ramirez v. Holder and Martinez v. Mukasey): reinforces that “admission” is “passage into the country from abroad,” so post-entry adjustments do not equal admission.

5) Due process and constitutional avoidance in immigration detention

• Zadvydas v. Davis: supplies the court’s strongest avoidance principle: interpret statutes to avoid serious constitutional problems, especially where liberty interests are at stake.
• Demore v. Kim: the government’s key benchmark for immigration detention; the Tenth Circuit distinguishes it as upholding categorical mandatory detention only where Congress made robust findings (criminal recidivism/flight).
• Mathews v. Diaz: cited in Demore and repeated here for the proposition that Congress has broad immigration authority, but not immunity from constitutional scrutiny.
• Reno v. Flores: invoked to confirm that due process applies in deportation/removal contexts and that “blanket presumptions” can sometimes justify detention—yet the court emphasizes the absence of comparable legislative findings here.
• Carlson v. Landon: used (via Demore) to show historical acceptance of categorical detention where Congress identified a defined class and an articulated security justification.
• Kwong Hai Chew v. Colding: referenced for the stronger due process protections for persons inside the country than at the border, amplifying the avoidance concern if § 1225(b)(2)(A) were extended inland.

6) The circuit split the opinion joins

The Tenth Circuit aligns with the “border-limited” reading adopted by: Barbosa da Cunha v. Freden (2d Cir. 2026), Lopez-Campos v. Raycraft (6th Cir. 2026), and Hernandez Alvarez v. Warden, Fed. Det. Ctr. Mia. (11th Cir. 2026), and rejects the government-favorable reading in Buenrostro-Mendez v. Bondi (5th Cir. 2026) and Avila v. Bondi (8th Cir. 2026).

It also references ongoing litigation in other circuits and a Seventh Circuit deadlock in Castañon-Nava v. U.S. Dep't of Homeland Sec., underscoring the issue’s national urgency and likely Supreme Court destination.

Legal Reasoning

1) The operative statutory hinge: “applicant for admission” vs. “seeking admission”

The court treats the two phrases in § 1225(b)(2)(A) as separate constraints. “Applicant for admission” is a term of art defined in § 1225(a)(1) to include: (i) those who arrive, and (ii) those present without having been admitted. But “seeking admission” is not defined; the court applies ordinary meaning (“request,” “ask for”) and emphasizes the grammatical force of the present participle (“seeking”) as denoting ongoing conduct.

The result is a functional, process-based interpretation: one “seeks admission” when one is actively pursuing lawful entry (or has an ongoing request for it), which fits naturally at the border. By contrast, a person who already crossed unlawfully and has no pending request to enter cannot sensibly be described as “seeking” entry.

2) Rejecting the government’s redundancy theory

The government argued that being an “applicant for admission” necessarily means “seeking admission,” rendering the latter phrase redundant. The court rejects this because it relies on the ordinary meaning of “applicant,” while the INA supplies a statutory definition that includes interior presence without admission. That definition does not describe actual “application” behavior; it assigns a legal status category.

3) The “deemed” argument is treated as an overreach

Drawing on dissenting analyses from other circuits, the government leaned on the word “deemed” in § 1225(a)(1) to argue Congress created a legal fiction: if someone is “deemed” an applicant, they must also be “deemed” to be seeking admission. The Tenth Circuit refuses the move for three reasons:

1. Textual/structural: § 1225(a)(1) functions as definitional language, and “deemed” is routinely definitional in federal statutes (confirmed by TC Heartland LLC v. Kraft Foods Group Brands LLC).
2. Separation-of-terms: Even if “deemed” creates a fiction, courts cannot extend it to additional, unstated attributes (“seeking”) absent statutory text.
3. Major-questions-like intuition: a single word in a definitional clause cannot silently authorize an enormous detention expansion (“mousehole/elephant” logic).

4) Context within § 1225 confirms a border focus

The court reads § 1225 as a border-processing statute (title, repeated “arriving/arrive” language, vehicle-search provisions for those “being brought” into the country), noting only one express interior-facing provision (§ 1225(b)(1)(A)(iii)(II)). Against that background, the absence of interior language in § 1225(b)(2)(A) supports a border-limited construction.

5) Harmonizing § 1225 and § 1226; avoiding collapse of § 1226(c)

A major structural argument is that the government’s reading would effectively remove inadmissible noncitizens from § 1226(a), making the inadmissibility-specific exceptions in § 1226(c) largely meaningless. Nielsen v. Preap prevents salvaging this by recasting § 1226(c) as a free-standing detention authority.

6) Purpose cannot override text

The government’s narrative—Congress wanted to eliminate “entry doctrine” advantages for interior unlawful entrants—was treated as, at most, a plausible policy account. The court responds that IIRIRA altered only “certain aspects” of the old regime, and purposive argument cannot overcome the enacted language.

7) Constitutional avoidance as confirmatory reasoning

Without deciding the constitutional question, the court concludes the government’s construction would pose serious due process concerns under Zadvydas v. Davis by authorizing mass, bondless civil detention without the sort of categorical congressional findings that supported detention in Demore v. Kim and Carlson v. Landon. That “serious constitutional questions” threshold is sufficient to reinforce the narrower statutory reading.

Impact

1) Immediate operational effect in the Tenth Circuit

Within the Tenth Circuit, the ruling substantially constrains the government’s July 2025 detention policy: many interior detainees previously classified under § 1225(b)(2)(A) will be governed by § 1226(a) and must receive a bond hearing (or release), shifting the default from categorical detention to individualized custody determinations.

2) Litigation dynamics and habeas practice

The decision will likely accelerate habeas petitions in the circuit seeking (i) bond hearings, (ii) corrected statutory classification, and (iii) relief for prolonged detention. It also provides a roadmap for challenging agency reinterpretations that attempt to repurpose border-processing statutes for interior enforcement.

3) National uniformity and Supreme Court review pressure

With the Tenth Circuit joining the Second, Sixth, and Eleventh against the Fifth and Eighth, the split becomes more entrenched and geographically consequential. The opinion’s reliance on statutory text, Jennings’s structural description, and Preap’s limitation of § 1226(c) gives the Supreme Court multiple doctrinal hooks for eventual resolution.

4) Doctrinal significance beyond immigration

The opinion illustrates a post-Loper Bright Enters. v. Raimondo method of weighing longstanding executive practice as contextual evidence—without deference replacing judicial judgment. It also models how constitutional avoidance can play a stabilizing role where agency reinterpretations would produce sweeping liberty deprivations.
