Ah, I see it. Don't know how I missed that on first skimming. Yup, a committee "claiming to represent" the West pilots can apply to the arbitrator to be designated as a separate merger committee for the West list. I think USAPA would be smart to take this deal, it still sends all three lists intact into negotiation/arbitration AND it seems to set a Dec 9, 2013 "default" snapshot for the lists (although still disputable by interested parties, guarantee the West would dispute it)

I make no predictions for how it's going to go down. But I think it's a reasonable offer. They give up their "hard won" exclusion of the West, but gain quite a bit in return. They could lose these lawsuits and find themselves completely shut out.
