A scandal at the Colorado Bureau of Investigation prompted the biggest criminal justice bill of the session. It ensures defendants and victims are notified if DNA evidence in their case may have been tampered with. It passed both chambers unanimously.

Colorado lawmakers blared "Final Countdown" from the state Senate's speakers and rushed three dozen bills to the finish line Wednesday before adjourning at 7:22pm. Why it matters: The last day of the legislative session is the most important — the make-or-break moment for hundreds of proposed new laws.

A bill that took up hours of debate in the Colorado legislature in its final week passed late Tuesday night. HB25-1312, "Legal Protections for Transgender Individuals," known as the Kelly Loving Act.
