Idaho House Bill 270 (HB 270) is a 2025 law in the state of Idaho that revises the state's indecent exposure law. It was signed into law by Governor Brad Little on March 26, 2025 and entered into legal force immediately through an emergency clause.
House Bill 270 has been criticized as being anti-transgender. According to the author of HB 270, Jeff Cornilles, it was introduced in part due to the Canyon County Pride Festival in 2024.
House Bill 270 considers exposing breasts as a misdemeanor. It includes a provision affecting transgender women, stating that exposed breasts that have been hormonally or medically altered also count as a misdemeanor. It separately considers "truck nuts" or other genitalia-related products on public display as a misdemeanor as well. Anybody actively breastfeeding a baby, even in public, is exempt from the law. If somebody is charged with three misdemeanors under the law within 5 years of each other could be charged as a felony and sentenced to five years in prison.
