NEW YORK — Luigi Mangione’s September murder trial in Manhattan will not go forward as scheduled.
New York Supreme Court Justice Gregory Carro issued an order Monday establishing a new briefing schedule for Mangione’s explosive bid to dismiss his state prosecution following his guilty plea in federal court — and pushing the case’s next court date into December.
The one-page order, signed by Carro on August 17, directs the Manhattan District Attorney’s Office to respond to Mangione’s defense motion by October 9, 2026.
Mangione’s attorneys will then have until October 30, 2026 to file their reply.
Carro set the next adjourned date for December 10, 2026.
The order effectively wipes out the state trial schedule that had Mangione headed toward jury selection on September 8.
And it puts one question squarely at the center of the Manhattan case:
Can New York prosecute Mangione for murder after he has already pleaded guilty in federal court to stalking Brian Thompson with the intent to kill him and causing Thompson’s death?
Federal Guilty Plea Upended the State Case
Mangione pleaded guilty Friday in Manhattan federal court to two federal stalking charges stemming from the December 4, 2024 killing of UnitedHealthcare CEO Brian Thompson.
During his plea, Mangione admitted under oath that he planned the attack and shot Thompson in Manhattan.
The federal plea carries potentially enormous consequences for the separate prosecution being handled by Manhattan District Attorney Alvin Bragg’s office.
Almost immediately after Mangione entered the plea, his attorneys, led by Karen Friedman Agnifilo, filed a motion seeking dismissal of most of the remaining New York charges under the state’s double-jeopardy protections.
The defense is seeking dismissal of seven of the eight remaining state counts, including second-degree murder and weapons charges.
The Manhattan District Attorney’s Office has made clear that it intends to fight that motion and continue pursuing the state prosecution.
Now Carro has formally given prosecutors until October 9 to make that case.
September Trial Is Off
The practical consequence of Monday’s order is immediate.
Mangione had been scheduled to begin jury selection in his Manhattan criminal case on September 8.
That is no longer happening.
Instead, the parties will spend the next several months litigating whether there can legally be a Manhattan murder trial at all.
Carro’s order does not decide Mangione’s double-jeopardy motion.
It does not dismiss the indictment.
And it does not indicate how Carro ultimately intends to rule.
What it does do is establish that the dismissal question will be briefed before the state case moves forward.
The October deadlines also give both sides substantial time to address what is likely to become one of the most consequential legal questions in the prosecution.
New York’s Double-Jeopardy Law Is the Battleground
The defense challenge is particularly significant because New York provides protections against successive prosecutions that can extend beyond the federal Constitution’s separate-sovereigns doctrine.
That distinction could prove critical.
Under federal constitutional law, state and federal governments generally may prosecute the same person for conduct arising from the same incident because they are separate sovereigns.
New York law, however, separately restricts successive prosecutions based upon the same act or criminal transaction, subject to statutory exceptions.
That is the opening Mangione’s defense team is attempting to use.
His attorneys contend that after Mangione’s federal guilty plea, New York cannot simply prosecute him again for the same killing under differently labeled state offenses.
The Manhattan District Attorney’s Office is expected to argue that the state offenses survive New York’s statutory double-jeopardy framework and fall within applicable exceptions.
That battle will now unfold on paper before Carro.
An Extraordinary Turn in an Already Extraordinary Case
The development represents a dramatic reversal from where the Manhattan prosecution stood only days ago.
Mangione was approaching a September trial.
Court preparations were underway.
Then came Friday’s federal guilty plea.
Within hours, the defense turned that plea into the centerpiece of an effort to eliminate the state murder prosecution entirely.
Now the September trial has disappeared from the calendar.
Instead, prosecutors have until October 9 to explain why New York should still be permitted to try Mangione.
The defense gets the final written word on October 30.
And the parties will return before Carro on December 10.
Mangione’s federal sentencing is currently scheduled for December 18, eight days after that state appearance. He faces the possibility of life imprisonment in the federal case.
That creates an extraordinary December calendar: Mangione is now scheduled to return to Carro’s Manhattan courtroom on December 10, followed eight days later by federal sentencing before U.S. District Judge Margaret Garnett.
Whether there will ultimately be a New York murder trial at all may depend on what Carro decides after the October briefing is complete.
For now, one thing is certain:
The September trial is off. The double-jeopardy battle is on.
