Giuliano Amato (Italian pronunciation: [dʒuˈljano aˈmato]; born 13 May 1938) is an Italian politician who twice served as Prime Minister of Italy, first from 1992 to 1993 and again from 2000 to 2001. Later, he was Vice President of the Convention on the Future of Europe that drafted the European Constitution and headed the Amato Group. He is commonly nicknamed dottor Sottile, (which means "Doctor Subtilis", the sobriquet of the Scottish Medieval philosopher John Duns Scotus, a reference to his political subtlety). From 2006 to 2008, he was the Minister of the Interior in Romano Prodi's government. On 12 September 2013, President Giorgio Napolitano appointed him to the Constitutional Court of Italy, where he has served since then.
