SANTA FE – A panel of federal appellate judges ruled Tuesday that New Mexico's seven-day waiting period on gun purchases likely infringes on citizens' Second Amendment rights, putting the law on hold pending a legal challenge.
The ruling by the 10th U.S. Circuit Court of Appeals sends the case back to a lower court. New Mexico's waiting period went into effect in May 2024, and does hold an exception for concealed permit holders.
“Cooling-off periods do not fit into any historically grounded exceptions to the right to keep and bear arms, and burden conduct within the Second Amendment's scope,” wrote Judge Timothy Tymkovich in the split 2-1 ruling. “We conclude that New Mexico's Waiting Period Act is likely an unconstitutional burden on the Second Amendment rights of its citizens.”
In a dissenting opinion, Judge Scott Matheson said New Mexico's waiting period “establishes a condition or qualification on the commercial sale of arms that does not serve abusive ends.”
The National Rifle Association and Mountain States Legal Foundation, an advocacy group for gun rights, filed the lawsuit on behalf of two New Mexico residents, citing concerns about delayed access to weapons for victims of domestic violence and others.
Democratic state lawmakers had enacted the restrictions in hopes of ensuring more time for the completion of federal background checks on gun buyers.
In a statement, Democratic Gov. Michelle Lujan Grisham expressed “deep disappointment” and said Tuesday's ruling was likely to cost lives.
“New Mexico's waiting period law was carefully crafted to minimize gun violence while respecting Second Amendment rights,” said Lujan Grisham, highlighting additional exceptions for gun purchases by law enforcement officers and transactions between immediate family members. “Waiting periods prevent impulsive acts of violence and suicide, giving people time to step back and reassess their emotions during moments of crisis.”
It was unclear whether the governor and legislators would request a broader review by a majority of judges on the 10th Circuit Court of Appeals.
Only California, Hawaii and Washington, along with the District of Columbia – have longer waiting periods than New Mexico that range up to 14 days, according to the Giffords Law Center to Prevent Gun Violence. Rhode Island also has a seven-day wait.
Michael McCoy, director of the Mountain States Legal Foundation's Center to Keep and Bear Arms, applauded the ruling. The group is also challenging Colorado's minimum three-day waiting period for gun purchases, enacted in 2023.
“The court found that there was no analogous law from that era that would support the modern day law that's at issue,” McCoy said. “For now, it means New Mexicans can go buy their firearms without an arbitrary delay imposed.”
