Civil liberties groups have filed a lawsuit challenging Louisiana’s new law mandating that the Ten Commandments must be displayed in every public school classroom. Plaintiffs in the suit filed Monday include parents of Louisiana public school children, represented by attorneys with the American Civil Liberties Union, Americans United for Separation of Church and State, and the Freedom From Religion Foundation. Opponents argue that the law is a violation of separation of church and state and that the display will isolate students, especially those who are not Christian. Proponents say the measure is not solely religious and has historical significance. In the language of the law, the Ten Commandments are “foundational documents of our state and national government.”
