First, one has to define what something is the end of, or glean that from context. I think that the westies are saying that the DJ will be the end of the Nic fight. An appeal to the 9th, if requested to be expedited by the parties (USAPA may wish to delay but they would have to file the appeal if they lose in Silver's courtroom), would be fairly quick compared to getting a contract. SCOTUS is unlikely to take the case, just as it was unlikely to take the Addington but it could take some time for that to make itself clear. Like ripeness, a DJ setting out a parties rights/responsibilities as a party to a contract is a routine matter, not groundbreaking, which is why the 9th and SCOTUS very unlikely to get involved.
I don't think any westie believes, or means to imply, that Silver will put a combined contract in place and deny a chance for membership ratification of that contract. All I think she'll do is tell the company what their obligation is in respect to the TA as it applies to the Nic.
