So, a Federal Appellate Court has issued binding case law dictating the content of public prayer - How is this not a “law regarding the establishment of religion”?
Well, it’s not really “binding” if it’s unenforceable. What are they going to do, put a “Prayer Monitor” in the council room, and taze anyone who starts to utter the word Jesus? These commissioners have the right idea, civil disobedience, which can only result in two outcomes: either the State tries to enforce this law, in a way that will reveal their true draconian nature to the public, or they will have to back down. Either way, we win.
The First Amendment reads "Congress shall make no law..."
This is the courts, not Congress. So, it's O.K. /s
