City of Tulsa v. Hooper
The Supreme Court refused to pause a Tenth Circuit ruling that had undercut Tulsa's claimed legal authority to enforce its municipal laws against American Indians, letting the case return to the trial court for further proceedings.
The order is temporary and procedural, leaving the core question of city enforcement power over American Indians unresolved while the litigation continues.
How it got here: A federal trial court dismissed Hooper's challenge, ruling the city had jurisdiction under the Curtis Act; the Tenth Circuit reversed and remanded; Tulsa then asked the Supreme Court to pause the Tenth Circuit's ruling.
The Case in Depth
What happened
Justin Hooper, an American Indian, challenged the City of Tulsa's authority to enforce its municipal laws against him. The city argued that a federal law from 1898 — the Curtis Act — gave it jurisdiction over all residents, including American Indians. The dispute raises a broader question about whether local governments in Oklahoma, which includes substantial Indian Country territory, can police American Indians the same way they police everyone else.
The question before the Court
Can the City of Tulsa enforce its own municipal laws — like traffic rules — against American Indians living within the city?
The Court's answer
No — the Court declined to pause the Tenth Circuit's ruling while the case continues. The denial was driven largely by the interlocutory (mid-case, not-yet-final) posture of the dispute: the trial court had not yet finished addressing all the arguments, and the Tenth Circuit itself left open a potentially important one — whether a separate 2022 Supreme Court ruling called Oklahoma v. Castro-Huerta independently gives the city enforcement authority over American Indians.
Because that argument remains available to the city on remand, and because the Tenth Circuit's ruling does not actually prevent the city from continuing to enforce its laws during the litigation, the urgency needed to justify pausing the ruling was absent. The underlying question of whether Tulsa can lawfully enforce its municipal laws against American Indians is not yet decided.

Why it matters
Tulsa and other Oklahoma cities still face legal uncertainty about whether they can enforce traffic, safety, and other municipal rules against American Indians living within their limits. In the meantime, a justice's statement noted that nothing in the appeals court ruling actually stops the city from continuing to enforce its laws while the case works through the courts.
What changes now
The case returns to the federal trial court in Tulsa, where the city can raise the argument that Oklahoma v. Castro-Huerta independently authorizes its enforcement power over American Indians. The Tenth Circuit has not resolved that question, so it remains fully open. Justice Kavanaugh noted that the city can continue to enforce its municipal laws against all persons as the litigation continues. This stay denial is not a final ruling on the merits.
What this does not decide
The Court did not decide whether Tulsa may lawfully enforce its municipal laws against American Indians. It also did not decide whether the Castro-Huerta reasoning applies to city-level jurisdiction. Both questions remain open for the lower courts to resolve in further proceedings.
Concurrences and dissents
Concurrence — Justice Kavanaugh
Justice Kavanaugh, joined by Justice Alito, wrote separately to flag that the underlying question — whether Tulsa can police American Indians within the city — is important. He explained that the stay was properly denied because the case is still mid-litigation and the Tenth Circuit left open a key argument under Oklahoma v. Castro-Huerta. He also noted that nothing in the Tenth Circuit's ruling prevents the city from continuing to enforce its laws in the meantime.
How the Court got there
The legal reasoning, step by step
- The Court was asked to pause (stay) the Tenth Circuit's ruling while the city appealed. Emergency stays are granted only when the applicant can show, among other things, that it faces serious irreparable harm without a pause and that it is likely to ultimately win the appeal — a high bar, especially in mid-case procedural postures.
- The Tenth Circuit had reversed the trial court, ruling that the Curtis Act of 1898 — a federal law passed to help organize what was then Indian Territory — does not give Tulsa jurisdiction over municipal violations committed by American Indians. But the appeals court deliberately stopped short of deciding a second possible basis for city authority: the reasoning of Oklahoma v. Castro-Huerta (2022), a recent Supreme Court decision addressing state criminal authority over non-Indians in Indian Country.
- Because the Castro-Huerta argument remains open and available to the city when the case returns to the trial court, the city's ultimate chance of winning on enforcement authority was not foreclosed by the Tenth Circuit's ruling. The emergency-stay calculation therefore tilted against pausing the appellate ruling at this early stage.
- Justice Kavanaugh's statement also emphasized that the Tenth Circuit's ruling does not actually bar the city from continuing to enforce its laws against all persons, including American Indians, while the litigation proceeds — further undercutting any claim of urgent, irreparable harm that would justify an emergency pause.
