LITTLE ROCK, Ark. — Seven Arkansas families filed a lawsuit Wednesday challenging an upcoming state requirement that public school classrooms have posted copies of the Ten Commandments, saying the new law will violate their constitutional rights.

The federal lawsuit challenges a measure Republican Gov. Sarah Huckabee Sanders signed into law earlier this year, similar to a requirement enacted by Louisiana and one that Texas’ governor has said he’ll sign.

The Arkansas law takes effect in August and requires the Ten Commandments to be prominently displayed in public school classrooms and libraries.

“Permanently posting the Ten Commandments in every classroom and library — rendering them unavoidable — unconstitutionally pressures students into religious observance, veneration, and adoption of the state’s favored religious scripture,” the lawsuit said.

The suit was filed on behalf of the families by the American Civil Liberties Union, Americans United for the Separation of Church and State and the Freedom from Religion Foundation. The lawsuit names four school districts in northwest Arkansas — Fayetteville, Bentonville, Siloam Springs and Springdale — as defendants.

A spokesperson for Fayetteville schools said the district would not comment on pending litigation, while the other three districts did not immediately respond to requests for comment.

A spokesperson for Attorney General Tim Griffin said his office was reviewing the lawsuit and considering options.

Attorneys for the families, who are Jewish, Unitarian Universalist or nonreligious, said they planned to ask the federal judge in Fayetteville for a preliminary injunction blocking the law’s enforcement. The attorneys say the law violates longstanding Supreme Court precedent and the families’ First Amendment rights.

“By imposing a Christian-centric translation of the Ten Commandments on our children for nearly every hour of every day of their public-school education, this law will infringe on our rights as parents and create an unwelcoming and religiously coercive school environment for our children,” Samantha Stinson, one of the plaintiffs, said in a news release.

Louisiana was the first state to enact such a requirement, and a federal judge blocked the measure before it was to take effect Jan 1. Proponents of Louisiana’s law say that ruling only applies to the five school boards listed in the suit, but The Associated Press is unaware of any posters being displayed in schools as the litigation continues.
