November 12, 2026 — Informational legal-news update. Facts in this article are current as of November 12, 2026.
On November 11, 2026, the petitioners in Viramontes v. Cook County, No. 25-238, submitted a response asking the Supreme Court to keep the case alive. Cook County had urged the Court to dismiss the case as moot, or as improvidently granted, after one petitioner asked to withdraw. Oral argument remains set for Wednesday, December 2, 2026, in this case and in a consolidated companion, Grant v. Higgins, No. 25-566.
What the Court agreed to decide
On June 30, 2026, the Court granted review in both cases as to the question presented in Viramontes: “Whether the Second and Fourteenth Amendments guarantee the right to possess AR-15 platform and similar semiautomatic rifles.” The cases were consolidated and allotted one hour of oral argument. On September 4, 2026, the Court set argument for December 2. On November 9, it granted the Solicitor General’s motion for leave to participate in oral argument as an amicus curiae and for divided argument.
Viramontes comes from the U.S. Court of Appeals for the Seventh Circuit and challenges Cook County, Illinois’s ban on many semiautomatic rifles. Grant v. Higgins challenges Connecticut’s ban. The Second Amendment Foundation, a petitioner in both cases, describes the Connecticut law as a ban on commonly owned semiautomatic rifles, both by name and by feature set.
What “moot” means here
A case becomes moot when the underlying dispute is no longer live—when a court no longer has a real controversy to decide. Federal courts need a genuine, ongoing dispute. If a case is moot, the Court generally will not decide it. The Court can also dismiss a case as “improvidently granted,” a procedural off-ramp used when the justices conclude the case is no longer a suitable vehicle for the question they agreed to hear.
On October 29, 2026, petitioner Cutberto Viramontes filed a motion under the Court’s Rule 46.2 asking to be dismissed from the case. Cook County later stated that the motion did not provide a basis for the request. This article does not speculate about why it was filed.
On November 5, Cook County filed a suggestion of mootness. The county argued that if Viramontes is allowed to withdraw, it is doubtful that any remaining petitioner has standing to litigate the question presented, and that the Court should then dismiss the case as moot or as improvidently granted.
The county’s main target is the other individual petitioner, Christopher Khaya. Unlike Viramontes, who had said he wanted a Smith & Wesson M&P AR-15-style rifle, Khaya has said he wants an IMI Galil semiautomatic rifle, a design the petitioners have described as largely based on the AK-47. The county argues that the Galil falls outside the question the Court agreed to decide, that the record does not show it is “similar” to an AR-15 or in common use, and that the two petitioner organizations—the Second Amendment Foundation and the Firearms Policy Coalition—identified only Viramontes and Khaya as Cook County members.
What the November 11 response says
The petitioners’ response, submitted by counsel David H. Thompson of Cooper & Kirk, argues that the question is not limited to AR-15-platform rifles. It covers “AR-15 platform and similar semiautomatic rifles.” If “similar semiautomatic rifles” meant only AR-15 variants, the petitioners say, that phrase would do no work. An AK-47-style rifle such as the IMI Galil, they argue, qualifies as similar.
They also point to the county’s own positions. Cook County’s ordinance groups the AR-15, the AK-47, and the Galil together, classifies them as so-called “assault weapons,” and bans them, both by features and by name. In its merits brief, the county defined the firearms listed by name in that ordinance—including the AR-15, the AK-47, and the Galil—as “AR-15 platform weapons.” The petitioners say the county has waived, or at least forfeited, any argument that the Galil falls outside the question presented.
They further argue that even if an AR-15 itself had to remain in the case, it still would. Accompanying declarations say Khaya also wants to acquire an AR-15-platform rifle if it were lawful in Cook County, and that Ed Smolen, a Cook County resident and member of both petitioner organizations, has owned an AR-15 since 2011, keeps it out of state, and would possess it at his Cook County residence if the law allowed. The response asks the Court to deny the county’s request.
As of November 12, 2026, the docket does not show a ruling on Viramontes’s motion to withdraw or on the county’s suggestion of mootness.
Why the second case matters
Even if the Court were to drop Viramontes, the same question would still be before the justices in Grant v. Higgins. Cook County itself noted, in a footnote, that the jurisdictional issue it raised in Viramontes “would not prevent the Court from deciding the question presented given that Grant v. Higgins … was consolidated with this matter.” The petitioners made the same point.
The Second Amendment Foundation said in a November 11 statement that it will be in the courtroom on December 2 “whether in Viramontes or our second case, Grant.” Executive Director Adam Kraut said that “no matter what the Court decides on Viramontes, we will still have the opportunity to present our case to the Justices on Dec. 2.”
What it means for Pennsylvania
Pennsylvania does not have a statewide ban on AR-15-platform or similar semiautomatic rifles today. A Supreme Court decision on this question would set the national rule. That matters in states and localities that already ban these rifles, and it would set the constitutional baseline for any future proposal in Pennsylvania. The Court has not yet heard argument, and this article does not predict the outcome.
Bottom line: Cook County has asked the Supreme Court to dismiss Viramontes v. Cook County as moot after one petitioner sought to withdraw. The petitioners submitted their response on November 11 and say a live case remains. A consolidated companion, Grant v. Higgins, presents the same question. Oral argument remains set for December 2, 2026. As of November 12, 2026, the Court has not ruled on the mootness request.
