The Ten Commandments won’t go into effect in some Louisiana classrooms until November.

BATON ROUGE, La. (AP) — Louisiana will not take official action to enforce a law requiring the Ten Commandments to be posted in all public school classrooms until at least November, pending a lawsuit. A federal judge approved the deal Friday.

The case was filed in June Parents of children from various religious backgrounds in Louisiana public schools said the law violated the language of the First Amendment, which prohibits the government from establishing religion and guarantees religious freedom. Supporters of the law argue that the Ten Commandments belong in classrooms because the commandments are historic and part of the foundation of American law.

Louisiana law requires the ordinances to be enacted by Jan. 1, a deadline unaffected by Friday’s agreement. The defendants in the lawsuit — state education officials and several local school boards — pledge not to post the ordinances in classrooms before Nov. 15 and not to develop regulations to implement the law before then.

Lester Duhey, a spokesman for Louisiana Attorney General Liz Murrill, said the defendants “have not taken any public compliance measures until Nov. 15” to allow time for pleas, arguments and a sentencing.

In 1980 the The US Supreme Court ruled A similar law in Kentucky violated the Establishment Clause of the U.S. Constitution, which states that Congress “shall make no law respecting an establishment of religion.” The Supreme Court ruled that the law had no secular purpose, but served a religious purpose.

In 2005, the Supreme Court ruled in a Kentucky case that such scenes were unconstitutional. At the same time, the court upheld the Ten Commandments on the grounds of the Texas State Capitol in Austin.

Louisiana’s new law does not require school systems to spend public money on Ten Commandments posters. This allows organizations to accept donated posters or pay for displays.

The law specifically recognizes, but does not require, other features in public schools, including: the Mayflower Compact, signed by the Pilgrims on the Mayflower in 1620 and often referred to as America’s “first constitution”; the Declaration of Independence; and the Northwest Ordinance, which established a government in the Northwest Territory — today’s Midwest — and paved the way for the admission of new states to the Union.

The legal challenge to the law came shortly after two-term Democratic Gov. John Bel Edwards was signed into office in January by Republican Gov. Jeff Landry. Landry’s inauguration marked a complete GOP takeover of state government in a Bible Belt state where the party already held every elected office in the state and a majority in the Legislature.
