 (EU). However, it does bear some resemblance to a confederation or federation. The EU operates common economic policies with hundreds of common laws, which enable a single economic market, open internal borders, a common currency and allow for numerous other areas where powers have been transferred and directly applicable laws are made. However, unlike a federation, the EU does not have exclusive powers over foreign affairs, defence and taxation. Furthermore, laws sometimes must be transcribed into national law by national parliaments; decisions by member states are taken by special majorities with blocking minorities accounted for; and treaty amendment requires ratification by every member state before it can come into force.

However, academic observers more usually discuss the EU in the terms of it being a federation;
