Senate approves state-court remedy for alleged constitutional violations during civil immigration enforcement after hours of debate

The Colorado Senate passed Senate Bill 5 on Feb. 23, 2026, establishing a state civil cause of action for people who say federal constitutional rights were violated during civil immigration enforcement.

Senator Weissman, a sponsor, told colleagues the bill creates a forum for claims that federal remedies alone do not fully address, saying the measure "is simply provide a forum to even get into the question" of whether rights guaranteed by the U.S. Constitution were violated. He noted federal defendants may still assert immunities but argued the bill restores a path to court for people who otherwise have no remedy.

Opponents warned the measure, as drafted, could produce many lawsuits and significant costs. Senator Carson said the bill "sounds very reasonable" in isolation but warned that the availability of attorney fees and damages could encourage mass filings and settlements that ultimately fall on taxpayers. Senator Liston and others raised public-safety and recruitment concerns, saying broad liability could make it harder to hire law enforcement and first responders.

Lawmakers considered several floor amendments. An amendment (L008) adding proximate-cause language was adopted. Other proposed amendments that would have imposed a "knowingly and intentionally" mental-state requirement (L004) and that would have excluded causes of action during declared disasters (L007) or narrowed the bill to sworn federal officers (L006) were debated and failed on the floor. A separate amendment (L005) intended to bar causes of action where the plaintiff provoked the conduct also failed on a roll call after division.

Debate repeatedly returned to two central tensions: whether the state should create a separate remedy for alleged federal constitutional violations and how to guard against frivolous lawsuits while preserving access to redress. Sponsors argued the bill is narrowly focused on civil immigration enforcement; opponents said the language is broad enough to sweep in many actors and to create large local costs.

The committee of the whole earlier reported the bill amended and recommended passage on second reading; the Senate adopted the committee report and, after consideration of on-floor amendments, the body adopted the bill. The Senate chair announced that "the ayes have it, and senate bill 5 is adopted." The transcript does not provide a final roll-call tally for the third-reading final passage in the floor discussion captured here.

Next steps: SB5, as amended, was ordered engrossed and placed on the calendar for third reading and final passage according to the committee report language; the Senate record shows the bill was adopted on the floor on Feb. 23, 2026.
