it's more like a .. asymmetric confederation. Democratically elected leaders, conspire together in a confederation, to elect a body that is above and beyond the leaders of the democracy. I honestly don't think we have a proper label for what the EU [edit* council] has become. If you are looking at it from the OP's perspective, it's more of a "democratic deficit." It is an institutional design that prioritizes efficiency, expert consensus, and national vetoes over direct voter control and transparency.
