Louisiana's plan to mandate the display of the Ten Commandments in all public school classrooms has been postponed until at least November, following a decision by a federal judge.

According to CNN US, the delay comes in response to a lawsuit initiated in June by Louisiana public school parents from diverse religious backgrounds.

They argued that the law contravenes the First Amendment, which prohibits the government from establishing a religion and ensures religious freedom.

Gov. Jeff Landry of Louisiana defended the law, suggesting that the Ten Commandments are crucial for classrooms due to their historical significance and foundational role in US law.

However, this stance is contentious given past US Supreme Court rulings. In 1980, the Court deemed a similar Kentucky law unconstitutional for violating the Establishment Clause of the US Constitution, which prohibits Congress from enacting laws that establish religion. The ruling stated that the law had a predominantly religious intent without any secular purpose.

Moreover, in 2005, while the Supreme Court ruled against displays of the Ten Commandments in Kentucky courthouses for violating constitutional principles, it allowed a Ten Commandments marker on Texas state Capitol grounds in Austin, indicating nuanced views on such displays depending on context.

Republican state Rep. Dodie Horton told USA Today: "I'm confident we will prevail in court."
