Idaho’s attorney general asked the justices to intervene after a lower-court judge blocked a section of Idaho’s abortion statute targeting doctors. The judge said the provision violates a federal law that requires hospitals receiving Medicare funding to guarantee emergency care. In its brief order Friday, the justices allowed the Idaho law to take full effect for now and said they would review the matter on an expedited basis in April.

The Biden administration turned to the Medicare law as a narrow way to challenge state-level abortion bans in federal court after the Supreme Court’s conservative majority overturned the fundamental right to an abortion established decades earlier in Roe v. Wade. The effort was seen as one of the few paths the administration could pursue to preserve access to abortion, which remains a galvanizing and divisive issue across the country in the lead-up to the 2024 presidential election.
