Ever heard of TABOR?  Turns out that the People of the State of Colorado can change the founding documents of the State when they deem a need to do so.  And the necrotic O&G industry, in their fits of arrogant stupidity like building a frack well site 200 feet from a high school football field, or dumping $345,000 of influence money into a local election, or turning the COGCC into a sock puppet, is badly over-reaching.
