2026 Colorado Proposition 135

Legislative Council's Blue Book uses gender-affirming nine times on Prop 135.

Legislative Council staff's 2026 Blue Book analysis of Proposition 135 uses the term gender-affirming nine times, while the ballot title and the measure's text describe surgery to alter a minor's biological sex characteristics.

Protect Kids Colorado, which urges a yes vote on the measure, asked the staff in writing to replace the term.

The Legislative Council staff's 2026 Blue Book analysis of Proposition 135, a measure that would prohibit certain surgeries for minors, uses the term gender-affirming nine times.

The ballot title printed on Colorado ballots for the November 3, 2026, election never uses the term, and neither does the text of the measure, whose short title is the Protect Children from Irreversible Sex Change Surgery Act.

The ballot title describes surgery for the purpose of altering the minor's biological sex characteristics, the same language the measure uses.

Those nine uses in the Proposition 135 analysis are the only appearances of the term anywhere in the 2026 State Ballot Information Booklet.

In its summary of the measure, the analysis says the prohibition includes gender-affirming surgeries, which are a range of procedures that may be provided to transgender individuals to make their physical appearance match their gender identity.
