SALT LAKE CITY (AP) — A committee of Utah lawmakers pushed forward a bill that would bar doctors from performing abortions sought because the fetus has Down syndrome.

The House Judiciary committee voted Thursday night to send the measure to a vote on the House floor despite concerns from some lawmakers that the proposal is likely unconstitutional and will leave the state facing a costly legal challenge.

Legislators supporting the measure, including bill sponsor Rep. Karianne Lisonbee, contend abortions based on a diagnosis of Down syndrome are “a eugenic-like eradication” of an entire class of people.

The measure would make it a misdemeanor for a doctor to perform an abortion knowing that the pregnant woman is seeking it because of a diagnosis or suspicion that the fetus has Down syndrome. The genetic abnormality can cause developmental delays and medical conditions such as respiratory and hearing problems and heart defects.

Doctors could face up to a year in jail and a $2,500 fine under the proposal, but women seeking such abortions would not be charged.

The House Judiciary committee’s vote in favor of the measure followed an emotional, two-hour hearing Thursday night where people with Down syndrome and other disabilities and the parents of such children spoke for and against the measure.
