While I agree that the process seems absurd on the face of it, I don't think it's as nonsensical as it appears at first glance.

It's way, way easier to have a small group of people re-interpret a static text over and over than it is to have a larger group of people, accountable to an even larger group of constituents, write new text that they all agree on over and over.

edit: I guess basically what I'm saying is that democracy is hard and this is a nice out?
