Obama's disregard for authority

We just listened to a Fox report about Obama's recent dictate for the provision of birth control for all.  At public cost!  No authority to make that edict.  So, what I want to know is if it is not within his authority to make this decision why is there not a backlash - a legal backlash by those from whom that authority would have to come.  Why does no one DO anything about it?  To do a thing without legal authority means the act is illegal.  Is that a wrong conclusion?  Now, I am listening to an "unlicenced Glock"in the pocket of the first hand man of David Brock - now committed to a "quiet room".  (Daily Caller, Tucker Carlson)  So it is known that the man carries and unlicensed gun and nothing is done about that?
