Utah's AG and Governor are stating their support for the Big 12 and their right to enforce rules.
Another thing of note is that part of the case the Big 12 is making is that Texas Tech has in the past voted to sanction a member school, so they acknowledge the Big 12's right to do so. They still have the same president and athletic director as they had when they voted to sanction Baylor in 2016.
So to me it would seem things are crumbling around Texas Tech. Their attempt to sue/threaten everyone into compliance doesn't seem to have worked. Also, with two different cases going in, the NCAA's (attempt to expedite an) appeal and the Big 12's, just one needs to succeed to put this madness to an end. But... I never would have thought a judge would allow an injunction against such a basic rule as you can't gamble on your own team's events so what do I know.
