Colorado
Colorado state laws, regulations, court decisions, and active legislation
Overview
Colorado has emerged as a nationally significant legal trendsetter, particularly in cannabis regulation, criminal justice reform, and environmental policy. The state was one of the first two to legalize recreational marijuana in 2012, establishing a regulatory model that has been widely replicated. Colorado's TABOR (Taxpayer's Bill of Rights) amendment is a unique constitutional provision requiring voter approval for tax increases.
The state's legal framework has evolved significantly in recent years, with major reforms in police accountability (eliminating qualified immunity at the state level), tenant protections, environmental regulation, and sentencing reform. Colorado's political landscape has shifted from a swing state to one with consistent progressive legal developments.
Court Structure
Colorado's court system includes county courts (limited jurisdiction), district courts (general jurisdiction trial courts), the Colorado Court of Appeals, and the Colorado Supreme Court. Judges are initially appointed by the governor from a list provided by a nominating commission, then face retention elections. Water courts handle water rights disputes — a critical legal area in this arid state.

Driving Under the Influence (DUI) and Driving While Ability Impaired (DWAI)
Colorado distinguishes between DUI (0.08%+) and DWAI (0.05%+, impaired to slightest degree). First DUI carries 5 days to 1 year in jail and 9-month license revocation. Colorado has a 5 ng/mL THC per se limit for marijuana DUI. A lifetime lookback applies for all priors.
Colorado Marijuana Code – Adult-Use Regulations
Colorado, a pioneer in marijuana legalization since 2012, allows adults 21+ to possess 2 ounces and grow 6 plants. Combined 30% state taxes generate over $400 million annually for schools, mental health, and local government. The state's regulatory model has influenced other states.

Colorado does not cap security deposits but requires return within 60 days (30 if lease specifies), with triple damages for wrongful withholding. Local rent control is now permitted after 2024 reforms. 60 days' notice is required for large rent increases. Just cause eviction protections are being implemented.
