A federal lawsuit filed Tuesday challenges a recent piece of Idaho legislation dubbed the “Abortion Travel Ban,” which makes it the first state to make it illegal for an adult to help a minor obtain an abortion across state lines.

The complaint, Matsumoto v. Labrador, was filed in U.S. District Court for the District of Idaho on behalf of three plaintiffs, the Northwest Abortion Access Fund (NWAAF), the Indigenous Idaho Alliance (IIA), and one individual plaintiff, Lourdes Matsumoto. The complaint claims that Idaho has some of the most “oppressive criminal abortion statutes in the United States,” and brings claims under the First Amendment, the 14th Amendment due process clause, and the right to travel within and between states.
