But aren't all of these initial decisions? That is, I don't expect that this is decided until there's a Supreme Court decision. There's still two levels of appeal to go before we get there.
Certainly the first five above all look to be trial court decisions which generally aren't citable law, but can be informative. It will almost certainly get to the Supreme Court at some point, it's too big an issue; until then we'll (probably) have a couple of different appellate court opinions to wait for.
I guess that depends on whether these cases are being appealed or if there is a "circuit split." Which is to say, those are the conditions I'm aware of under which a lower court decision does not constitute a decision decision.
As always, IANAL, but I do listen to their podcasts often (IANALBIDLTTPO)
