Strictly speaking the only thing before the court is who is entitled to vote, which will be determined by a declaratory judgment. A mediation will allow the parties to discuss and potentially settle broader issues.
Here is Chapter 2, Section 3 of the bylaws:
No member shall deliver a notice of withdrawal to the Conference in the period beginning on July 24, 2011, and
ending on August 1, 2024; provided, that if any member does deliver a notice of withdrawal prior to August 1,
2024, in violation of this chapter, the Conference shall be entitled to an injunction and other equitable relief to
prevent such breach, and if a court of competent jurisdiction shall deny the Conference such injunctive relief,
the Conference shall be entitled to retain all the media and sponsorship rights in the multi-player video distribution (MPVD) and telecommunications/wireless categories of the member purporting to withdraw through August 1, 2024, even if the member is then a member of another conference or an independent school for some or all intercollegiate sports competitions. Additionally, if a member delivers notice of withdrawal in violation of this chapter, the member’s representative to the CEO Group shall automatically cease to be a member of the CEO Group and shall cease to have the right to vote on any matter before the CEO Group. (6/10, 10/10, 7/11)
The tricky part is what I highlighted in bold. The conference is not seeking an injunction. IMO, WSU and OSU don't want an injunction keeping other schools around. So, how do you get to the result of the conference (with WSU and OSU as the only voting members) retaining the MPVD and other stuff? If you are WSU and OSU, I think you get the declaratory judgment saying you are the sole voting members, then amend the bylaws. That's a bit underhanded and likely to result in prolonged litigation, so it makes sense to see what kind of settlement you can get.
