A federal magistrate judge has blocked a Trump administration Affordable Care Act rule change related to abortion billing, declaring it without “reasoned explanation” and giving state Attorney General Letitia James and others in her coalition of states a hard-fought victory.

“In sum, agencies can change their policies when they provide a reasoned explanation for the change,” wrote U.S. District Magistrate Judge Laurel Beeler of the Northern District of California in addressing a Department of Health and Human Services change to the ACA that would have required separate abortion-based insurance billing.
