Civil rights advocates are asking the U.S. Supreme Court to review a Texas law that requires the display of the Ten Commandments inside public school classrooms.

The state approved the bill just over a year ago, which requires public school classrooms to post a "durable poster or framed copy" of the Ten Commandments with specifications for size and typeface.

The law was upheld earlier this year by a federal appeals court, which also approved of a similar law in Louisiana.
