Colorado gun dealers just pushed back hard against what looks like another state power grab. A federal lawsuit filed this month challenges HB26‑1126, the new law that expands dealer recordkeeping and lets state agents demand to inspect those records without a warrant. If you care about the Fourth Amendment or the privacy of lawful gun owners, this fight matters.
What the lawsuit actually says
On June 12, 2026, Centennial Gun Club and several other firearms dealers and associations filed a complaint in the U.S. District Court for the District of Colorado. The plaintiffs sue Governor Jared Polis, Attorney General Phil Weiser, and Heidi Humphreys, Executive Director of the Colorado Department of Revenue, in their official capacities. The suit, brought under 42 U.S.C. § 1983, says HB26‑1126 authorizes warrantless, suspicionless inspections of dealer transaction records and effectively builds a gun‑owner registry by collecting names, ages, and addresses for all retail firearm sales. Plaintiffs are asking the court to block enforcement of the law while the case moves forward.
Why this is a Fourth Amendment fight
The heart of the case is simple: the Fourth Amendment protects people and businesses from government searches that lack probable cause and a warrant. The complaint argues that letting state agents demand and review private sales records any time, with no defined scope and no review, chills lawful purchases and chills speech — because buying a firearm for lawful purposes is a protected right. Dealers say they will be forced to choose between customer privacy and state demands. That’s not regulation — it’s surveillance dressed up as oversight.
The state’s paper promise doesn’t erase the problem
Supporters of HB26‑1126 will point to text in the law that expressly forbids agencies from using dealer records to create a registry. Fine — that line is in the statute. But a promise on paper doesn’t stop officials from compiling and using sensitive data in practice. The law also widened what dealers must record, required a state dealer permit to transfer guns, and gave peace officers the right to inspect records at will. That combination creates a real path to a de facto registry, even if lawmakers included a few reassuring words to calm critics.
Bottom line: this case will test limits of state power
This lawsuit is more than a narrow business dispute. It’s a test of whether the state can turn routine retail records into a surveillance tool and then hide behind statutory language to deny it. The court will soon decide whether to pause enforcement while lawyers brief the issues. If you value privacy, the rule of law, and the right of Americans to buy firearms without government snooping, pay attention. Government officials should be proving they protect citizens, not collecting lists that make private choices public — but in Colorado, that distinction is now on the judge’s desk.
