A basic rule in the adversarial system is party presentation: the parties “frame the issues for decision,” while the court serves as a “neutral arbiter” of the issues those parties present. United States v. Sineneng-Smith, 590 U.S. 371, 375 (2020). Chief Justice Roberts has famously described this principle as courts limiting themselves to “call[ing] balls and strikes,” rather than going to bat themselves. (And Justice Kagan has echoed the Chief’s phrase in the Court’s own opinions. See Lomax v. Ortiz-Marquez, 590 U.S. 595, 599 (2020).)
On the surface, the party-presentation principle seems as straightforward a rule as it gets. And it’s often treated as a discretionary rule: for nearly every example of parties failing to present an issue (commonly described as waiver or forfeiture), there’s an example of a court deciding to reach an issue anyway. But two recent Supreme Court rulings raise some unexpected nuances and questions as to how the Court is interpreting and applying that rule—as applied to both lower courts and to the Court itself.
In November 2025, the Court issued a per curiam summary disposition in a habeas case, Clark v. Sweeney. There, the Court held that the Fourth Circuit violated party presentation by granting habeas relief on a theory the petitioner never advanced. Mr. Sweeney had raised a single claim: that his trial counsel was constitutionally ineffective for failing to voir dire the entire jury to ensure that one juror’s misconduct had not tainted any other juror’s consideration of the case. The state court and federal district court both rejected that claim. On appeal, the Fourth Circuit reversed—but on a different theory. The Fourth Circuit ruled that “Sweeney’s trial was marred by a ‘combination of extraordinary failures from juror to judge to attorney’ that deprived Sweeney of his right to be confronted with the witnesses against him and his right to trial by an impartial jury.” It granted Sweeney a new trial on that theory. Judge Quattlebaum dissented, arguing the majority had “flout[ed]” party-presentation principles.
The per curiam Court (with no recorded dissenters) agreed with Judge Quattlebaum, holding that “[t]he Fourth Circuit’s radical transformation of Sweeney’s simple ineffective-assistance claim departed so drastically from the principle of party presentation as to constitute an abuse of discretion.” Although the Court’s ruling contained virtually no other reasoning, it invoked notice and due process concerns, observing in passing that the state never had a chance to address the new theory the Fourth Circuit had ruled on.
One month later, some Justices on the Court again grappled with the party-presentation principle in Trump v. Illinois. That case arose from President Trump’s attempt to federalize and deploy state National Guard troops in Chicago in the midst of immigration enforcement raids. Trump relied on 10 U.S.C. §12406(3), which empowers the President to federalize members of the National Guard if he is “unable with the regular forces to execute the laws of the United States.” The district court entered a temporary restraining order barring that federalization and deployment, and the government applied for a stay of that TRO from the Supreme Court. After primary briefing, the Court directed the parties to file supplemental briefing on an issue the parties had not addressed: the meaning of the term “regular forces” in § 12406(3). The Court then issued an order (with no attributed author) denying the stay application based on its interpretation of the term “regular forces.”
Justice Alito, joined by Justice Thomas, dissented. And one of the first issues he raised was party presentation. Citing Clark v. Sweeney, he argued that the Court had “unnecessarily and unwisely departed from standard practice” of deciding only the questions the parties choose to present, and had instead invited and accepted an “eleventh-hour argument” that respondents had “waived or forfeited … three times over” in the lower courts. According to Justice Alito, if the Court had doubts as to the parties’ agreed-upon interpretation of the term “regular forces,” it should have simply assumed the correctness of that interpretation for the sake of argument, as the Court has done in the past. And in Justice Alito’s view, the Court’s party-presentation error was compounded by the Court’s opining on “a host of important questions without adequate briefing, consideration, or explanation.”
Despite their brevity, these two recent invocations of party presentation have not gone unnoticed. The outcomes of these two cases are also interesting considering that both cases departed from the usual format of the Court’s merits docket: Clark was a summary disposition in which the Court declined to ask for full briefing or argument, and Trump was an emergency stay application that also lacked full merits briefing or argument. Do abbreviated proceedings like Clark and Trump make strict adherence to party presentation more important or less important? On the one hand, the more limited the parties’ briefing, the less guidance the Court has when wading out beyond the arguments made. On the other hand, when parties have less time and opportunity to brief and argue, that increases the risk they may miss key issues, and might correspondingly increase the Court’s responsibility to cover ground the parties did not—particularly for urgent, hot-button issues. Given the increasing frequency with which the Supreme Court is addressing issues in similarly abbreviated fashions, we may start to get more guidance with how the Supreme Court expects courts to grapple with those tradeoffs.
