To further summarize, the East guys sued a few west guys-viewing their actions/suggestions/blog comments as a conspiracy against USAPA. (West guys calling the "free" 1-800 number just to rack up charges and suggesting to their fellow pilots that paying dues to an organization whose sole purpose is to pursue a DOH seniority list is detrimental to your best interests)
West guys are suing the East to mandate implementation of the Nicolau award since it was a binding arbitration, and the transition agreement between AW and USAir included terms regarding negotiating in good faith. And, no matter your opinion, negotiation does involve some give and take. Take it or leave it doesn't really constitute good faith negotiation in my opinion.
