Then explain exactly how CJ Moore violated the 1st Amendment, which forbids Congress from making any laws that touch on an establishment of religion. So the question is, what law did CJ Moore violate? It is religion-establishing laws that the constitution forbids.
So, if CJ Moore didn't violate a Congress-made law, then what law did he violate? If you can't find it, don't castigate yourself too harshly. Federal Judge Thompson couldn't find one either. He didn't let that omission stop him from issuing a lawless court order though.
I am not arguing the Constitutionality of Moore's monument, but whether or not he has the right to ignore the courts. I submit that he doesn't have that right, unless the courts' ruling violates God's law. Since there is nothing in Scripture that requires posting the Ten Commandments in a courthouse, the courts' ruling doesn't violate God's law, and thus Moore is bound not only by they Constitution, but also by Paul's command to obey those in authority, to remove the monument.
Clearly Thompson believed the Constitution or some other source of law (case law for instance) required the monument to be removed. We may not agree with him, but he is the governing authority in this case, per the Constitution, which states the SCOTUS and inferior courts have the power in all cases arising under the Constitution.
So when did Moore become a member of Congress, and what law did he establish?
