Even milestone documents such as the Single European Act and the Treaties of Maastricht, Amsterdam, and Nice, were never envisaged as achieving the kind of permanence (or even semi-permanence) that we normally associate with a constitution. The same is true of developments like the Union's common foreign and security policy or Monetary Union, with its Euro and European Central Bank.
即使是里程碑似的文件如单一欧洲法、马斯垂克条约、阿姆斯特丹条约、尼斯条约等，也从来没有想过要追求永恒。欧盟的外交和安全政策、以及欧洲货币同盟也是如此。
