Louisiana’s Attorney General on Friday issued a guidance to public schools on how they should display the Ten Commandments in classrooms by using sample posters behind any teacher’s desk or with other historical documents.

This was disclosed in a letter written by Attorney General Liz Murrill to school districts directing each school to select and display “at its discretion” one of the four sample posters, available on the attorney general’s website.

In the document, the attorney general’s office said that to avoid confusion about whether the display could be attributed to a teacher, “a school should place its displays on any classroom wall other than behind a teacher’s desk, podium or location from which a teacher ordinarily delivers instruction.”

“I have issued guidance to our public schools regarding compliance with Louisiana’s Ten Commandments law, H.B. 71. My guidance letter explains as much and includes four specific displays, as well as a draft resolution that schools may use to adopt this guidance,” Attorney General Liz Murrill said in the letter.

She also said the Ten Commandments should be displayed “among others reflecting educational content, such as those displaying the Mayflower Compact, the Declaration of Independence, and the Northwest Ordinance.”

Last year, lawmakers had directed that a copy of the Protestant version of the Ten Commandments be posted in every public school classroom. A group of parents had sued to block the law, and in November U.S. District Court Judge John deGravelles declared the mandate unconstitutional and temporarily barred the state from enforcing it.

The attorney general’s office has said the judge’s order applies only to five school districts identified in the lawsuit challenging the law and that other districts can post the Ten Commandments without violating an order from U.S. District Judge John de Gravelles.

The judge’s order, had directed the Board of Elementary and Secondary Education and the state’s education secretary to tell all districts about his decision — not just districts covering students in East Baton Rouge, Livingston, Orleans, St. Tammany and Vernon parishes.

The American Civil Liberties Union had written to school districts statewide last month saying that while they were not named defendants in the lawsuit, they could be sued if they didn’t protect the constitutional rights of their students.

“Even though your district is not a party to the ongoing lawsuit, and therefore is not technically subject to the district court’s injunction, all school districts have an independent obligation to respect students’ and families’ constitutional rights. Because the U.S. Constitution supersedes state law, public-school officials may not comply with H.B. 71,” ACLU said in the letter.

House Bill 71, is a bill passed by state Legislature passed last year, that requires public K-12 schools and colleges to post the Ten Commandments in every classroom by Jan. 1. A court hearing on the challenge to the law is scheduled for Jan. 23.
