The 10th U.S. Court of Appeals has slammed the brakes on the federal government’s attempt to keep immigrants locked up without any shot at a bond hearing, dealing a major blow to a no-bond detention push that had been roiling Colorado’s courts. In a unanimous 3-0 decision in Santillan Quiroz v. Mullin on Tuesday, the panel said the administration’s recent rewrite of immigration law stretches mandatory detention far beyond what Congress allowed at the border. The ruling sends the case back to the federal district court and could trigger swift bond hearings for detainees across the Rocky Mountain region.
What the opinion says
Judge Richard E.N. Federico, writing for Judges Robert E. Bacharach and David M. Ebel, homed in on a single phrase in the statute and its reach. The key language, the panel concluded, applies to people encountered "at the border," not to long-term residents living inside the United States. "The only time a noncitizen can be said to be seeking admission is when he is seeking to enter the United States at the border," the court wrote, according to the U.S. Court of Appeals for the 10th Circuit. Federico also noted that treating millions of people in the interior as automatically ineligible for bond would raise "serious" due-process concerns.
How the case began
The appeal centers on the detention of Rigoberto Santillan Quiroz, who the court says entered the United States in 2006 and then lived here for roughly two decades before his arrest and detention in November 2025. After an immigration judge and then a federal district judge agreed with the government’s new no-bond reading of the statute, Santillan Quiroz turned to habeas corpus to challenge his confinement. Filings in the case trace that timeline in detail, including appellate briefs from the ACLU of Colorado.
Impact in Colorado
Colorado’s federal bench has been inundated with habeas petitions from people in immigration custody arguing that the government wrongly cut them out of bond hearings. Most judges around the state have already rejected the administration’s expansive interpretation. In a sign that the legal tide was turning even before this week’s ruling, the U.S. Attorney’s Office in Colorado recently began filing responses that drop the sweeping no-bond argument, according to Colorado Politics. That shift alone could shrink the number of bruising habeas showdowns in district court, even as appeals percolate.
Where this leaves the national fight
The decision lands in the middle of a growing national split. Some federal appeals courts have rejected the no-bond regime while others have signed off on it, creating a patchwork that practically begs for U.S. Supreme Court intervention. The Associated Press has tracked the diverging rulings and the flood of district-court challenges they have unleashed. Until either Congress steps in or the justices settle the question, a detainee’s odds of getting a bond hearing will largely depend on which circuit their case falls into.
What's next for Santillan Quiroz
The 10th Circuit reversed and remanded, instructing the district court to treat Santillan Quiroz’s custody as governed by 8 U.S.C. § 1226(a). Under that provision, he must either receive a bond hearing or be released within seven days of the appellate mandate. The panel also gave the parties a 14-day window to seek rehearing. Those directives are laid out in the opinion and mandate, according to the U.S. Court of Appeals for the 10th Circuit.
Reactions and what to watch
Judges and lawyers in Colorado say the ruling provides a much-needed reset that should push many of these fights back to where they usually start: bond hearings in immigration court rather than full-blown habeas battles in federal court. Retired U.S. Magistrate Judge Kristen L. Mix told the Denver Gazette that "Habeas petitions will diminish if government officials adhere to the ruling by providing detention hearings." All eyes will also be on Chief U.S. District Judge Daniel D. Domenico, who has issued orders embracing a different reading of the law and is the subject of a recent nomination to the 10th Circuit, Colorado Politics reports, as lower courts now move to apply the panel’s directive.
