A Utah Supreme Court appeal stemming from Gabby Petito's 2021 murder could determine whether Charlie Kirk's family can move forward with a wrongful death lawsuit over alleged security failures at a Turning Point USA event last year, according to an attorney involved in the appeal.
Brian Stewart, an attorney for the Petito family, said Kirk's claims, if filed, would likely face dismissal under current Utah law unless the state's highest court overturns a 1996 decision known as Tiede.
«Right now, Kirk's claims, if filed, would likely be dismissed, like Gabby Petito's claims were dismissed on that basis,» Stewart said. «We would need the Utah Supreme Court to overturn Tiede to pave the way for Charlie Kirk's family to proceed.»
The Tiede decision upheld the dismissal of a lawsuit over the 1990 murders of Kay Tiede and her mother Beth Potts, two Texas women killed by men on parole who attacked their family after leaving a halfway house. The ruling affirmed the constitutionality of Utah's governmental immunity law as applied to wrongful death claims, which Stewart said are barred against governmental entities when the injury arises from a third-party assault or battery.
At the center of the Petito appeal is the argument that the Utah Constitution prohibits lawmakers from limiting or eliminating the right to recover for wrongful death. Her family's lawsuit against the Moab Police Department alleged that officers were negligent in their response to a traffic stop involving Brian Laundrie two weeks before he killed her. A judge dismissed the case on governmental immunity grounds.
In September, Kirk's family filed a notice of claim, a precursor to a lawsuit. Their attorneys alleged that Utah Valley University, the state of Utah and key officials failed to properly secure the event even after acknowledging responsibility for rooftop security, leading to his death on Sept. 10, 2025.
Among the claims in the filing, UVU Police Chief Jeffrey Long allegedly told Turning Point USA organizers «I got you covered» when they raised concerns about rooftop access around the campus courtyard. Prosecutors say a sniper perched on a rooftop on the other side of the courtyard shot and killed Kirk.
But that text message may not be enough to overcome Utah's expansive governmental immunity protections, Stewart said.
«It's another act of negligence that contributed to Charlie's vulnerability and ultimate death, but it really wouldn't change the applicability of the statute,» he said. «It's similar in the Petito case. The parents of Gabby might have brought her home, might have intervened, but they relied on the analysis of the police on the scene who said, it's no big deal, we're not even gonna arrest anybody.»
That created the impression that things were taken care of, he said, likening it to Long's alleged assurance.
The Petito family argues Tiede does not apply to its case and, if it does, should be overturned because the Utah Constitution says, «The right of action to recover damages for injuries resulting in death, shall never be abrogated.»
Lawyers for Kirk's family have also laid the groundwork for a potential federal claim, Stewart said.
Kirk's accused assassin, 23-year-old Tyler Robinson, pleaded not guilty through his own attorneys at his arraignment on Sept. 1. He could face the death penalty if convicted of the top charge of aggravated murder. He is due in court Friday afternoon for a scheduling hearing.
