Unless I want to mount an expensive and largely useless campaign against UT it looks as if I am going to have to pay the stupid parking ticket. I looked up the law regarding the powers of State funded colleges and found this. Section 51.202.a.3 makes it pretty clear that they have the legal right to make any stupid unjust regulation they choose.
I can still appeal the ticket one more time, but it seems pointless in light of the faceless bureaucracy, which is the UTPTS. Still I will try.
