From the Treaty establishing a Constitution for Europe (TCE), article I–3: “The Union’s objectives”. Full text of TCE available at http://tinyurl.com/k5yotml . The treaty was adopted by consensus by the European Convention in 2003 and signed by representatives of the then twenty-five member states of the European Union in 2004, but eventually rejected by French and Dutch voters in 2005. After a “period of reflection” it was then replaced by the Treaty of Lisbon, which entered into force in 2009.
