The main effect of the legislation, although it went unacknowledged by supporters, would prevent teenagers from receiving birth control without parental approval and make it a crime for a physician to provide care to a minor without parent consent.
The measure also reaffirms current law that allows parents to remove their children from sex education and opt out of immunization requirements, a conversation that comes as Colorado faces scrutiny for some of the most lax vaccination laws in the nation.
Republican lawmakers pushed the legislation — titled the "Parent's Bill of Rights" — because they said it was needed to prevent government intervention in parenting. Democratic critics labeled it a political manifesto that eroded children's rights.
