NPIP is pretty clearly constitutional. Unsure where you got your law degree. Perhaps you should consider suing them for the poor quality of their product.
While I have not looked at the specific structure of the TAHC, its general concept also fits easily wihin the traditional and constitutional roles of State goverment. Assuming no consitutional infirmities in the way its leadership is selected, my inclination is "constitutional", though they may overstep their constitutional bounds in some ways - TX is fond of ALJs, for instance (Administrative Law Judges), and there are real concerns when those who administer the rules also set the rules and judge when the rules are being followed - that's not our Constitutional structure at the TX state or Federal Level (though it is permissible in some extremely limited circumstances) - but I don't know that TAHC uses any ALJs - just that if I were looking for constitutional infirmities, I'd start there.
