Notables: 25 years of Legislative Bills that Shaped Colorado

Coloradans have always had a knack for voting with their conscience, not just their party. From the State Capitol to the ballot box, our history shows a consistent theme: we care about people. Over the past twenty-five years, voters and lawmakers alike have leaned into bold decisions around education, criminal justice, health care, the environment, and human rights.

Colorado has become a proving ground for big ideas; some controversial, some groundbreaking, but all fiercely debated. From pioneering marijuana legalization to reimagining clean energy, expanding reproductive rights to reforming criminal justice, the Centennial State has led national conversations time and again.

And through it all, Yellow Scene has been there; covering, questioning, and amplifying the voices of our communities. Here’s a look back at some of the most polarizing, widely publicized, and defining measures that shaped Colorado’s political landscape year by year:

2000
Amendment 20: Medical Marijuana
This amendment allowed for the legal use of medical marijuana, four years after California became the first state to permit medical cannabis.

2001
The School Safety Act: Student Safety
In the wake of the Columbine shootings, Colorado sought to address the problem at the root, enacting bullying-prevention measures. This act has undergone several adjustments and amendments as social media has evolved.

2002
House Bill 1404: Criminal Justice Reform
This bill required that an individual be convicted of a crime before their property could be seized. It also required that any seized property directly pertain to the crime—a major win for civil rights.

2003
SB 03-314: Family Rights
To protect children and families, this bill required that siblings in foster care or out-of-home placements be kept together whenever possible.

2004
SB 04-037: Criminal Justice / Mental Health Reform
With a growing number of individuals with mental health issues ending up incarcerated, the state created a prevention act to expand services, strengthen screening, and divert individuals from prison where appropriate.

2005
TABOR Referendums C and D: State Spending

• Referendum C, which passed, allowed the government to spend revenue above the constitutional limit in areas such as education, health care, and transportation.
• Referendum D, which would have expanded state borrowing capacity, was defeated.

2006
Amendment 41: Ethics in Government
This measure limited gifts to Colorado elected officials, capping them at $53 per year and banning gifts from lobbyists altogether. It also instituted a two-year “revolving door” rule, preventing former officials from lobbying within two years of leaving office.

2007
SB 07-025: Anti-Discrimination
This law prohibited employers from firing an individual based on sexual orientation or gender identity. Over the years, it has been amended to strengthen protections for gender identity.

2008
HB 08-1119: Criminal Justice Reform
This bill funded research into racial and ethnic disparities in the juvenile justice system, which disproportionately incarcerated BIPOC youth.

2009
HB 09-1293: Health Care Affordability Act
This bill imposed a provider fee on hospitals, using the revenue to fund state Medicaid programs as well as public health initiatives. Now moving toward universal health care, Coloradans still largely support the principle of care for all.

2010
HB 10-1365: Clean Air–Clean Jobs Act
This act required Xcel Energy to convert three coal-burning plants to natural gas. Its goal was to improve air quality and promote sustainability. The politicization of oil and gas remains a hot-button issue in Colorado.

2011
HB 11-1148: Disclosure of Health Care Employee Information
In a move for patient safety, this bill absolved health care employers of liability when disclosing information about prospective employees’ violent or drug-related histories if relevant to client well-being.

2012
Amendment 64: Recreational Marijuana Legalization
This nationally watched measure legalized recreational marijuana in Colorado. Yellow Scene Magazine supported the claim that marijuana is safer than alcohol.

2013
HB 13-1229: Gun Safety
In the wake of the Aurora theater shooting, this bill required universal background checks and mental health screenings for firearm purchases or transfers.

2014
Amendment 67: Women’s Rights (Defeated)
Voters rejected a measure that would have legally defined human life as beginning before birth, which could have criminalized abortion and miscarriage. Its failure preserved reproductive protections.

2015
Proposition BB: Education Funding
Using proceeds from marijuana taxes, this proposition allocated $66 million toward education funding.

2016
Amendment 70: Minimum Wage Increase
Voters approved raising the state’s minimum wage to $12 per hour. Yellow Scene Magazine has continued covering the importance of wage adjustments as costs rise.

2017
SB 17-207: Mental Health Crisis Response
This law allocated $7 million for crisis response teams to assist law enforcement, allowed for 72-hour mental health holds, and expanded facilities for those in crisis.

2018
Amendment A: Criminal Justice Reform
After failing in a prior year, this amendment successfully abolished slavery and involuntary servitude as punishments for crime, prohibiting unpaid prison labor.

2019
SB 19-181: Environment / Oil and Gas
This bill gave local governments greater authority to regulate oil drilling and fracking, an issue that directly impacted towns like Erie, Colorado.

2020
Proposition 114: Wolf Reintroduction
This measure directed Colorado Parks and Wildlife to create a plan for reintroducing gray wolves—a fiercely debated issue among ranchers, environmentalists, and animal advocates. Yellow Scene continues to cover its impacts.

2021
SB 21-173: Tenant Rights
Part of a package of criminal justice and housing reforms, this bill provided renters with a grace period before late fees and limited fee amounts. The 2021 session also saw significant sentencing reforms (e.g., HB 21-1250).

2022
HB 22-1279: Reproductive Rights
This law affirmed individuals’ rights to use or refuse contraception and to choose whether to carry or terminate a pregnancy. It also confirmed that life is not defined as beginning before birth. Yellow Scene covered this issue extensively.

2023
SB 23-169: Gun Safety
This law raised the legal age to purchase a firearm to 21, part of Colorado’s ongoing effort to reduce gun violence.

2024
Amendment J: Marriage Equality
This amendment repealed the outdated definition of marriage as solely between a man and a woman, affirming equality in marriage under Colorado law.

2025
Senate Bill 25-144: Family Leave
This extended care through the FAMLI medical leave plan to allow for parents to have an additional twelve weeks, making the total twenty-four, if their child was born needing neonatal care.
