A federal appeals court on Friday ruled, in a unanimous decision, in favor of a coalition of Louisiana parents who sued to block a state law that requires public schools and colleges to display the Ten Commandments in classrooms.

The 5th U.S. Circuit Court of Appeals’ order stems from a lawsuit filed last year by parents of Louisiana school children from various religious backgrounds, who said the law violates First Amendment language guaranteeing religious liberty and forbidding government establishment of religion.

Louisiana’s controversial law requiring public schools and colleges to post the Ten Commandments violates the U.S. Constitution and cannot be enforced, a federal appeals court ruled Friday.
