The U.S. Fifth Circuit Court of Appeals will hear arguments Tuesday about the constitutionality of Texas and Louisiana's Ten Commandments display laws.

The fight over posting the Ten Commandments in public school classrooms returned to court Jan. 20 when the full 17-judge panel of the Fifth Circuit U.S. Court of Appeals heard oral arguments in two cases challenging new laws in Louisiana and Texas. The court heard two hours of debate without rendering a decision.

In 2022, the Supreme Court largely abandoned the three-part Lemon Test, used to determine whether a law or governmental action violated the separation of church and state clause in the Constitution. It was set in place by the 1971 Supreme Court case Lemon v. Kurtzman.
