Anyway. In my mind, the Delegate is the source of all authority and power, and so any powers should flow from that position.
At the same time though, 'legitimacy' involves a certain level of respect for others. Sometimes erroneously called a democratic mandate. I think the Delegate has to balance their own power to a degree with the community.
So ideally a system would be cooperative between the Delegate, who holds the power, and some kind of assembly of the nations the Delegate leads.
I don't think this needs to be overly formalised. The absolute worst thing I can imagine is us getting bogged down in obsessions over laws and amendments and all that nonsense that makes TNP look so very tedious.
