I don't have a copy of the TA to review. However, assuming the truth of what you say it says and in the context of which you refer, it would ** appear ** to me that such a move by the company would bring about a lawsuit by the West pilots. That is just another possible reason why the company made a smart move if filing for declaratory relief.
However, there is a second thought that basically smacked me in the face when I re-read your question before submitting the above paragraph as my answer. DUH. The TA was signed by three parties. While it can be argued that the West no longer exists the company is not betting on a court seeing it that way. The Addington class is the closest thing to a group that represents west at this point yet I suspect that there are at least a few West USAPA MIGS who will claim that the Addington class does not represent them.
First off, HP, "May be modified by written agreement of the Association and the Airline Parties collectively" is actually a direct quote out of the TA, XII,B. Why question everything others post?
Yes, the TA was signed by three parties (actually five parties, but that's quibbling). According to the language in the TA, those three (5) parties were:"AWHC (America West)," "US Airways Group (US Airways)," "and the AIR LINE PILOTS in the service of AMERICA WEST and US AIRWAYS, respectively, as represented the AIR LINE PILOTS ASSOCIATION." So, two (or four) company participants, but only one union participant. The only union "signatory" to the TA was Duane Woerth. All the others union types there were merely witnesses.Those facts, HP.
The TA is very specific regards modification. USAPA superceded the "Association" as CBA, so USAPA can modify it, as it desires (granted, under penalty of an in novo DFR). The problem you have with arguing that the Addington "class" can sue the company is the fact that the TA (as-is or as modified) was "made and entered into in accordance with the provisions of the Railway Labor Act." As we found out with the early court losses by McIlveny two years ago, disputes belong under the jurisdiction of the system board, not the courts. Even the desert judge sent those to the SBA. Or have you forgotten those West losses?
If USAPA was really smart they would do something to undo their assimilation of the West as a group because there may be a need for USAPA to negotiate with the West, if anyone can now figure out who the West is.
To paraphrase Al Gore, where's the controlling legal authority that allows USAPA to negotiate with a group that exists outside the RLA?
HP, I got to hand it to you. You're like the Energizer Bunny. You prognosticated a USAPA 9th loss, lost that one big-time and went out to recharge your batteries. Now you're back. I'm reading much speculation and winging it in your posts. JMHO.
