There was a moment when the President of the Eurogroup decided to move against us and effectively shut us out, and made it known that Greece was essentially on its way out of the Eurozone. … There is a convention that communiqués must be unanimous, and the President can’t just convene a meeting of the Eurozone and exclude a member state. And he said, “Oh I’m sure I can do that.” So I asked for a legal opinion. It created a bit of a kerfuffle. For about 5-10 minutes the meeting stopped, clerks, officials were talking to one another, on their phone, and eventually some official, some legal expert addressed me, and said the following words, that “Well, the Eurogroup does not exist in law, there is no treaty which has convened this group.” So what we have is a non-existent group that has the greatest power to determine the lives of Europeans. It’s not answerable to anyone, given it doesn’t exist in law; no minutes are kept; and it’s confidential. So no citizen ever knows what is said within. … These are decisions of almost life and death, and no member has to answer to anybody.
