And who exactly is included in your "Those?" The Judiciary? The Executive branch? The Legislative branch? One of these? A combination of two or three of them? Or none of the above?
The Constitution spells it out. It's the law of the land. Isn't it clear what the functions of the 3 branches are? It's not rocket science. Do you think it requires a liberal elitist snob in a black robe to understand it's meaning, or can a citizen also understand it? I think the latter.
