United States v. Sineneng-Smith
The Supreme Court unanimously threw out a Ninth Circuit ruling that struck down a federal immigration law, finding that the appeals court had improperly hijacked the case by inviting outside advocates to raise a constitutional challenge the defendant had never argued.
The decision reaffirms that American courts are supposed to decide cases based on the arguments the parties actually bring — not issues the judges themselves choose to pursue.
How it got here: Sineneng-Smith was convicted in federal district court; the Ninth Circuit vacated her conviction after inviting outside amici to brief an overbreadth challenge she never raised; the United States petitioned the Supreme Court, which agreed to hear the case.
The Case in Depth
What happened
Evelyn Sineneng-Smith ran an immigration consulting firm in San Jose, California. She helped clients — mostly Filipino workers in the United States without authorization — file applications for a labor certification program, even though she knew they had missed the eligibility deadline by years. She charged each client roughly $6,800 and collected more than $3.3 million in fees, leaving her clients with worthless applications and no path to legal status.
The question before the Court
Can a federal appeals court take over a case by inviting outside groups to raise a constitutional argument the defendant's own lawyers never made, and then decide the case on that new argument?
The Court's answer
No — the Ninth Circuit panel abused its discretion when it departed so drastically from the party presentation principle, the foundational rule that parties frame the issues in a case and courts decide what the parties present. Rather than ruling on the arguments Sineneng-Smith's lawyers actually made — narrower First Amendment claims focused on her own conduct — the panel named three outside advocacy organizations as invited amici and asked them to brief a constitutional "overbreadth" challenge (the argument that a law sweeps in too much protected speech) that Sineneng-Smith had never raised. The panel then gave those outsiders more argument time than the defendant's own counsel.
No special circumstances justified this takeover. Sineneng-Smith had competent lawyers who made deliberate choices about which arguments to advance. A court is not rigidly bound by counsel's precise framing, but the Ninth Circuit's wholesale reinvention of the case went well beyond any recognized exception to the party presentation rule. The case is sent back to the Ninth Circuit to decide the appeal on the arguments the parties actually made.

Why it matters
Litigants across the country can rely on federal appeals courts deciding only the disputes they actually brought, not new theories judges find interesting. Prosecutors and defendants alike are protected from having their cases transformed mid-appeal by judges who appoint outside advocates and sideline the real parties' lawyers.
What changes now
The Ninth Circuit must reconsider Sineneng-Smith's appeal as though the panel's overbreadth detour never happened — deciding the case on the arguments her lawyers actually made, including whether the federal statute covered her conduct and whether it violated the First Amendment as applied specifically to her. Whether §1324(a)(1)(A)(iv) is facially unconstitutional on overbreadth grounds remains an open question the Supreme Court did not address.
What this does not decide
The Court does not decide whether the federal law against encouraging illegal immigration is constitutional as applied to Sineneng-Smith, whether it is unconstitutionally vague, or whether it is facially overbroad. Those questions go back to the Ninth Circuit. Justice Thomas's solo call to reconsider the overbreadth doctrine is not the Court's holding.
Concurrences and dissents
Concurrence — Justice Thomas
Justice Thomas agreed that the Ninth Circuit abused its discretion, but wrote separately to raise deeper doubts about the First Amendment overbreadth doctrine itself. He argued that the doctrine has no basis in the text or history of the First Amendment, that it departs from the normal rule that courts strike down laws only when no valid application exists, and that it violates Article III principles by letting litigants assert the free-speech rights of hypothetical third parties who are not before the court. He called for revisiting the doctrine in an appropriate future case.
How the Court got there
The legal reasoning, step by step
- The Court began with the 'party presentation principle' — the foundational rule of American adversarial litigation, articulated in Greenlaw v. United States (2008), that parties frame the issues for decision and courts serve as neutral arbiters of what the parties present. Courts are 'essentially passive instruments of government' that wait for cases to come to them and normally decide only the questions the parties raise.
- The Ninth Circuit panel departed dramatically from this principle. After the appeal was nearly ready for decision on the parties' own briefs, the panel named three outside advocacy organizations as invited amici and asked them to brief three questions the panel had selected — including a First Amendment 'overbreadth' challenge, which is a claim that a law punishes too wide a swath of protected speech. Sineneng-Smith had never raised that challenge at any stage of the case.
- The panel then gave the invited outside organizations 20 minutes at oral argument while cutting Sineneng-Smith's own counsel to 10 minutes. It ultimately ruled in line with the outsiders' arguments, striking down the federal immigration statute as unconstitutionally overbroad — a ruling the defendant's own lawyers had never asked for.
- No extraordinary circumstance justified the panel's takeover. Sineneng-Smith was represented by competent counsel throughout and had raised deliberate, self-regarding First Amendment arguments about her own conduct. Courts can make modest adjustments — correcting obvious miscalculations or protecting unrepresented defendants — but nothing like what the Ninth Circuit did here.
- The overbreadth doctrine itself is, as the Court has previously warned, 'strong medicine' that should not be 'casually employed.' That warning made the panel's decision to seek out and apply it on issues no party had raised even harder to justify. The Ninth Circuit's 'radical transformation of this case goes well beyond the pale.'
