Adawg & spqrzilla are correct.

Frankly, I'm baffled that anyone is surprised by this - particularly with the recent round of balking from the CU Regents.

Let me lay this out:
The PEOPLE of Colorado finally got it's elected officially to listen to them and pass this original piece of legislation that gave state level recognition of our Second Amendment rights.

The Regents of CU, believing that they are their own entity which can determine their own rules, laws, and manner of operating, felt that the laws of the State didn't apply to them. As such, they continued to restrict the Peoples 2A rights. After all, everyone knows that by prohibiting guns, bad guys can't/won't violate the force shield of regulation enacted by the All Powerful Regents of CU. They said "We are supreme beings of logic and science and have the insight to know that these inanimate object are truly vile and evil. These are the borders of our Utopia and those evil guns Shall Not Pass!"

This decision was challenged in the Courts by the People. The Courts decided that CU is an entity of the State and must abide by the laws of the State, without the freedom to pick and choose what they want to follow. The Courts said "the legislature has spoken".

With their panties in a twist because they were told they aren't as high & mighty as they believed, the Regents of CU began looking at the law and at the Courts decision. "You will not tell us what we can and can not do" was their cry. As collegiate "educators" which equates to being smarter than the rest of us, they found the chink in the Courts decision. "If we get the legislature to amend the law, we can regain our control".

And so it came to pass that the Regents of CU found a champion in a left-wind liberal gun-hater who had introduced legislation to correct the error previously made by the legislature which limited the control that the Regents of CU could wield.

The rest of the story is, as of yet, untold.
