NOT AN ATTORNEY, JUST MY .02
Tech's judge shopping ultimately found them one that would put an injunction on the NCAA until after the college football championship game. The only way imaginable to expedite the courts is to defy their order. That requires the Big 12 and NCAA to put teeth into a violation of this type and force an immediate hearing that can be appealed. I think Yormark has to issue a new bylaw that makes it possible for the league to vote by supermajority to reverse wins for violating this kind of NCAA bylaw, and dare Tech to play Sorsby, and see what Tech decides to do.
So much of the game Tech is playing right now is, "we are supporting the player, we don't need to do anything right now" treating it as a hypothetical which may be factually true but is quite full of ****. This only comes to a head if they play him. It is reasonable for the Big 12 to establish consequences for this hypothetical situation before the season just to make things perfectly clear.
Texas attorney general claims trying to do anything like this would lead to the state taking them to court, but it may not even be a legal issue. The conference establishes all obligations and penalties for its members by vote.
