The Supreme Court unanimously handed a crisis pregnancy center a victory last week in its bid to fight a subpoena seeking its donor list, marking a major win for both First Amendment rights and anti-abortion groups operating in states that allow access to abortion.

The justices ruled 9-0 Wednesday in favor of allowing First Choice Women’s Resource Centers, a crisis pregnancy center that provides support for expecting and new mothers, to challenge New Jersey’s sweeping subpoena in federal court. The high court’s opinion, written by Justice Neil Gorsuch, found that the pregnancy center had “established that the Attorney General’s demand for private donor information injures the group’s First Amendment associational rights.”
