The "No Harm Act" is designed to prohibit the use of federal funds for medical treatments that alter the sex traits of minors, aiming to restrict access to such treatments and establish clear guidelines around parental consent and healthcare provider responsibilities. The legislation introduces a complete ban on federal funding for any medical or surgical services intended to change an individual's sex characteristics. It empowers individuals, including taxpayers, to sue for damages if they believe federal funds have been misused for these treatments.
