Attorneys from Simpson Thacher & Bartlett have joined efforts with the American Civil Liberties Union and others to file a federal lawsuit this week on behalf of nine multifaith families in Louisiana in an attempt to block a new state law requiring all public schools to display the Ten Commandments in every classroom.

In addition to Simpson Thacher serving as pro bono counsel, attorneys from the ACLU, the ACLU of Louisiana, Americans United for Separation of Church and State, and the Freedom from Religion Foundation are also representing the plaintiffs, which includes parents of Jewish, Christian, Unitarian Universalist, and nonreligious backgrounds.
