In a blow to right-wing efforts to ban books and criminalize librarians, a federal judge on Monday struck down key provisions of an Arkansas law as unconstitutional—though the fight is far from over, with the Republican state attorney general planning to appeal.

Republican Gov. Sarah Huckabee Sanders signed Act 372 in March 2023. A few months later, U.S. District Judge Timothy Brooks temporarily blocked implementation of Sections 1 and 5 of the law—and on Monday, he ruled against them in a 37-page order.
