The UN is a "global power base" established by the 1% behind closed doors as a sort of "test" NWO. Right now it's not terribly efficient because it works for the corporate interest of the EU, US & Oil countries right now.
As for a "Bill of rights" I'm pretty sure that document is only a "flower" on the dung pile right now alongside the Constitution, well, the framers version anyway, until our global society breaksdown and reforms.
As long as superstition prevails, we will fall short of eradicating war, poverty, and hunger. -J. Fresco
