Colorado Proposition 133: Human Trafficking of a Minor, Current Penalty vs. Proposed Life Sentence

Of the three criminal-justice measures on Colorado’s November 3, 2026 ballot, Proposition 133 proposes the single biggest sentencing change: it would take a charge currently punished the same way as many serious felonies and make it the only sex offense in Colorado carrying a mandatory sentence of life in prison without parole.

How Colorado Law Treats This Charge Today

Under C.R.S. § 18-3-504(2), human trafficking of a minor for sexual servitude is a class 2 felony. Because this specific offense is also classified as a crime of violence under C.R.S. § 18-1.3-406, the court cannot use the ordinary class 2 felony range. Instead, under sections 18-1.3-401 and 18-1.3-406, the judge is required to sentence a person convicted of this offense to at least the midpoint of the presumptive range — 16 years — and may go up to twice the maximum, or 48 years. In practice, that makes the real sentencing range for this charge 16 to 48 years in prison, plus 5 years of mandatory parole.

Current law already removes several defenses that might otherwise apply: it is not a defense that the minor consented, that the defendant didn’t know the minor’s age, or that the minor or someone else represented the minor as being 18 or older. Today, buying commercial sex from a minor, standing alone, is typically prosecuted under separate, generally lesser statutes — such as soliciting for child prostitution or patronizing a prostituted child — rather than as trafficking itself.

What Proposition 133 Would Change

Proposition 133 would make two changes to this statute:

• It would raise the offense from a class 2 felony to a class 1 felony and require courts to impose a mandatory sentence of life in prison without the possibility of parole upon conviction — removing judicial sentencing discretion for this charge entirely.
• It would expand the definition of the crime to include knowingly trading anything of monetary value to buy or sell sexual activity with a minor — meaning conduct often charged today under separate, lesser statutes could instead be prosecuted as trafficking, carrying the same mandatory life sentence.

This is a statutory measure, so it needs only a simple majority to pass.

The Debate

Supporters, including the group Protect Kids Colorado, argue that child sex trafficking is among the most serious crimes a person can commit and that a mandatory life sentence reflects that severity and may deter would-be offenders. Opponents, including the Colorado Coalition Against Sexual Assault, argue that sentencing decisions should stay with judges who can weigh the specific facts of each case, and warn that a blanket mandatory life sentence — combined with the existing strict-liability provisions in the statute — could produce harsh outcomes for trafficking victims themselves who were coerced into recruiting or transporting other minors.

What This Means If You’re Facing This Charge Now

If Proposition 133 passes, it would govern conduct charged for offenses committed after its effective date — it would not convert an existing charge for past conduct into a class 1 felony carrying mandatory life. But it’s worth understanding that current law is already aggressive on this charge: the existing strict-liability provisions mean defenses like consent or mistake of age aren’t available even today. Anyone under investigation or charged in this area needs experienced counsel immediately, regardless of how this measure turns out.
