doorman discretion
That immense amount of power conferred upon one without commensurate knowledge, experience, or understanding, such that, in effect, the village idiot ends up holding the keys to the U.S. nuclear arsenal, or worse, won't let you into your own office building so you can finish working on that one document that will define the rest of your career and is due tomorrow morning.
I apologize for not filing that brief brief with the supreme court on time, but I was the victim of doorman discretion.
