I want to know the answer to the following question:
When did the US Court of Appeals rule in the case of ACLU v. Mercer County?
All the background I'm provided with is that "On December 20, 2005, the United States Court of Appeals for the Sixth Circuit ruled in the case of ACLU v. Mercer County that the continued display of the Ten Commandments as part of a larger display on American legal traditions in a Kentucky courthouse was allowed, because the purpose of the display (educating the public on American legal traditions) was secular in nature.". Is that enough to answer the question?
Answer: yes
