Lisbon Treaty: Year I

The completion of the ratification of the Lisbon Treaty (from now on the Treaty) in November and its entry into force on 1 December 2009 marked the end of an extraordinary and unprecedented lengthy process of institutional change of the European Union. The Treaty had been signed on 13 December 2007, almost two years before its entry into force, by no means an excessive duration compared to the ratification of previous modifications of the Treaties. But the Treaty – in strictly legal terms a substantial set of amendments to two previous treaties renamed in the process – has a long history. Initial proposals for institutional reform date back to the German reunification in 1989-1990. They went through lengthy debates that eventually led to the European Convention and the 'Draft Treaty establishing a Constitution for Europe' of 20031 and from there to the 'Treaty establishing a Constitution for Europe' of 20042. If the current form of the Treaty is a clear consequence of the difficulties of the ratification process of the Constitution, the ideas that provide the substance can be traced back to the final years of the past century. The pages that follow are not a legal analysis but an attempt to identify changes and to assess their significance3.
