U.S. District Judge Timothy Brooks found that elements of the law are unconstitutional.
“I respect the court’s ruling and will appeal,” Arkansas Attorney General Tim Griffin said in a statement to The Associated Press.
The law would have created a new process to challenge library materials and request that they be relocated to areas not accessible to children. The measure was signed by Republican Gov. Sarah Huckabee Sanders in 2023, but an earlier ruling had temporarily blocked it from taking effect while it was being challenged in court.
“The law deputizes librarians and booksellers as the agents of censorship; when motivated by the fear of jail time, it is likely they will shelve only books fit for young children and segregate or discard the rest,” Brooks wrote in his ruling.
