A federal appeals court has upheld a ruling allowing the Ten Commandments to remain on display at Kentucky's Mercer County courthouse.

A three-judge panel ruled in December that the display is constitutional because its purpose is historical rather than religious.

The panel cited that fact that the Commandments are displayed alongside replicas of nine other historic documents, including the Bill of Rights and Declaration of Independence.

The judges also noted that the font size is the same for all of them, and there was no attempt to put the religious document at a higher level.

The full court refused to reconsider the case. But a dissenting judge argued that the display was similar to those in two other Kentucky counties that the U.S. Supreme Court determined were unconstitutional last year.
