One Reentry, Two Prosecutions: The Double Jeopardy Case That Could Redraw Federal Immigration Enforcement

The Constitutional Absurdity Problem

The Supreme Court’s October 13 argument in the Oklahoma double-prosecution case exposed something rare at One First Street: genuine cross-ideological bewilderment at the government’s litigation position. Justices Sotomayor and Gorsuch—who agree on little else—both pressed the government to explain how a single act of illegal reentry under 8 U.S.C. § 1326 can support two separate federal prosecutions without running afoul of the Double Jeopardy Clause’s command that no person shall “be subject for the same offence to be twice put in jeopardy of life or limb.” U.S. Const. amend. V.

The government’s theory, as described in the argument, treats what looks like one continuous course of conduct as two distinct criminal episodes—effectively allowing prosecutors to slice a single reentry into multiple charges. Sotomayor called the arrangement a “constitutional absurdity,” and Gorsuch’s questioning suggested he shares the concern. When those two converge on a criminal-procedure issue, practitioners should pay attention: the resulting coalition often produces surprising majorities.

The Blockburger Framework Under Stress

Under the familiar test from Blockburger v. United States, 284 U.S. 299 (1932), two offenses are distinct for double jeopardy purposes only if each requires proof of an element the other does not. The question here is more elemental: whether the underlying conduct—the act of reentry itself—constitutes one offense or two in the first place. That is not a Blockburger problem; it is a unit-of-prosecution problem, the same analytical knot the Court confronted in Bell v. United States, 349 U.S. 81 (1955), and Sanabria v. United States, 437 U.S. 54 (1978).

The practical stakes are considerable. Illegal reentry under § 1326 is among the most frequently prosecuted federal offenses in the country. If the Court holds that a single reentry cannot support successive prosecutions, it would constrain a charging strategy that has given federal prosecutors significant leverage in plea negotiations—particularly in border districts where § 1326 cases dominate the docket.

The Court has historically resolved unit-of-prosecution ambiguities in favor of defendants under the rule of lenity. See Bell, 349 U.S. at 83. If the justices follow that tradition here, the decision could invalidate pending second prosecutions and force U.S. Attorneys’ offices to consolidate charges they have been bringing separately.

A Term Defined by Criminal-Law Retrenchment

The double-jeopardy argument does not exist in isolation. It arrives during a term in which the Court has shown a consistent—if not always coherent—impulse to narrow federal criminal enforcement across multiple fronts.

Consider the pattern. In June, a unanimous Court limited the reach of the federal statute barring firearm possession by certain drug users, upholding dismissal of a charge against a Texas marijuana user. That 9-0 decision signaled that even this Court—with its expansive Second Amendment jurisprudence post-New York State Rifle & Pistol Ass’n v. Bruen, 597 U.S. 1 (2022)—is willing to cabin federal criminal statutes when they sweep beyond their textual or constitutional moorings.

The same week, the Court reinstated the 2017 murder conviction in the Etan Patz case, holding that the Second Circuit’s grant of habeas relief conflicted with the Antiterrorism and Effective Death Penalty Act of 1996, Pub. L. No. 104-132, 110 Stat. 1214. That decision reinforced AEDPA’s deliberately narrow gate for federal-court review of state convictions under 28 U.S.C. § 2254(d)—a reminder that the Court’s skepticism runs in both directions: it is suspicious of prosecutorial overreach and of judicial overcorrection.

And in May, the Court’s 6-3 decision rejecting First Step Act sentence reductions for inmates seeking relief based on intervening changes in sentencing law—with Justice Barrett writing for the majority—closed another door that lower courts had cracked open. The First Step Act, Pub. L. No. 115-391, 132 Stat. 5194 (2018), was Congress’s most significant criminal-justice reform in a generation, but this Court has consistently read its provisions narrowly.

The Appointments Crisis Simmers Beneath

Layered over these doctrinal developments is a structural problem that threatens the integrity of federal prosecutions themselves. The Ninth Circuit ruled that Sigal Chattah was not validly serving as Nevada’s top federal prosecutor. The Third and Second Circuits reached similar conclusions regarding Alina Habba in New Jersey and John Sarcone in the Northern District of New York. The Justice Department has petitioned the Supreme Court to reverse the Ninth Circuit’s ruling.

These are not abstract separation-of-powers disputes. Under the Appointments Clause, U.S. Const. art. II, § 2, cl. 2, and the Federal Vacancies Reform Act, 5 U.S.C. §§ 3345–3349d, the validity of a U.S. Attorney’s appointment determines the validity of every indictment, plea agreement, and sentencing recommendation issued under their authority. If the Supreme Court ultimately sides with the circuits, the downstream consequences—motions to dismiss, challenges to convictions, requests for new trials—could be enormous.

What Practitioners Should Watch

Defense attorneys with pending § 1326 cases involving successive prosecutions should preserve double-jeopardy objections now. If the Court rules against the government, the window for raising meritorious claims will be narrow, and unpreserved objections will face plain-error review under Fed. R. Crim. P. 52(b)—a far steeper climb.

More broadly, the convergence of Sotomayor and Gorsuch on this issue reflects a jurisprudential realignment on criminal procedure that has been building for years. Both justices have expressed skepticism about prosecutorial charging practices that multiply exposure from unitary conduct. Cf. Ramos v. Louisiana, 590 U.S. 83 (2020) (Gorsuch, J., joined by Sotomayor, J., in relevant parts). A majority built on that axis would be durable and difficult for future administrations to litigate around.

The Court has not yet decided the case. But the oral argument’s tone suggests the government’s “double prosecution” theory is in serious trouble—and with it, a charging playbook that federal prosecutors in high-volume immigration districts have relied on for years.
