The Biden administration had argued that emergency-room doctors treating pregnant women had to provide terminations if necessary in Idaho, which has one of the country's strongest abortion bans.
The Democratic administration had given similar guidance to hospitals nationwide in the wake of the Supreme Court 2022 decision overturning the right to abortion. It's being challenged in other conservative states.
In Idaho, the state argued that its law does allow life-saving abortions and the Biden administration wrongly sought to expand the exceptions. The state agrees with the dismissal, so it does not need judicial approval, Justice Department attorneys wrote in court documents.
A judge has temporarily blocked Idaho from any abortion ban enforcement that would change emergency treatment.
In his first term, Trump appointed many of the Supreme Court justices who voted to overturned Roe v Wade. He has since said the issue should be left to the states.
The Supreme Court stepped into the Idaho case last year. It ultimately handed down a narrow ruling that allowed hospitals to keep making determinations about emergency pregnancy terminations but left key legal questions unresolved.
The case went before the 9th U.S. Circuit Court of Appeals in December. Those judges have not yet ruled.
