1) I'd merely observe that the mou that was floating around did nothing to confirm, much less establish the nic, nothing whatsoever. This was a potential agreement between the union and the company. This, to me, rather strongly suggests that your first premise is necessarily faulty. I submit my admittedly cynical opinion that this whole business with the attempt at a declaratory judgment was little more than an obvious delay tactic from team tempe, and did not at all necessarily reflect any huge degree of concern per issues of potential liability. We can both only guess at what company thought was truly put into the process.
2) As no contract in contemporary times can ever be made truly free from possible, subsequent litigation; I'd again suggest the presence of demonstrated flaws in that logic. Neither of us really expected to see any freedom from suit come forth from the court. To assume that the company, were it to demand the nic, would magically become free from any/all post ratifcation legal issues is again an unreasonable notion. In this "Best of All Possible Worlds" we inhabit...well...it's pretty much obvious that were we to shop courts around; we'd likely find one that would even accept suit against the sun for it's rising in the morning, versus the evening.
I believe, in order to accept your argument here; one must assume that even with two courts now ruling that the nic need not indeed be the final product, that there still exists an overwhelming company concern for post contract ratification liability. If such truly exists at all; neither of us can now know to what extent it would effect company decisions. (Then too; were this matter not left in the hands of the representing union...well..since when does the company otherwise determine pilot seniority...and how it must be done?) IF...a large if indeed, management sees any real need for an agreement with the pilot groups for use in pursuing a merger...well...again; we simply can't do more than guess at what they're willing to do for such. The previously referenced mou would suggest precious little immediate concern for a nic-or-nothing contract.....to say the very least. It must also be fairly noted that said mou was put forth prior to the proceedings in Judge Silver's courtroom.
