As well as the enlargement and Amsterdam Treaty, the Prodi Commission also saw the signing and enforcement of the [[Treaty of Nice]] as well as the conclusion and signing of the [[Treaty establishing a Constitution for Europe|European Constitution]]: in which he introduced the "Convention method" of negotiation. The treaty was signed by European leaders on 26 February 2001 and came into force on 1 February 2003.

It amended the [[Maastricht Treaty]] (or the Treaty on European Union) and the [[Treaties of Rome|Treaty of Rome]] (or the Treaty establishing the European Community which, before the Maastricht Treaty, was the Treaty establishing the European Economic Community). The Treaty of Nice reformed the institutional structure of the European Union to withstand eastward expansion, a task which was originally intended to have been done by the [[Treaty of Amsterdam|Amsterdam Treaty]] but failed to be addressed at the time. The entry into force of the treaty was in doubt for a time after its initial [[Twenty-fourth Amendment of the Constitution Bill, 2001 (Ireland)|rejection by Irish voters]] in a referendum in June 2001. This referendum result was reversed in a subsequent referendum held a little over a year later.
