This stipulation was later included verbatim in the Treaty of Nice, which entered into force on 1 January 2003, and also forms an integral part of the Lisbon Treaty, serving as the constitutional basis of the EU since 1 January 2009.
Ta določba je bila pozneje dobesedno vključena v Pogodbo iz Nice, ki je začela veljati 1. januarja 2003, in je hkrati sestavni del Lizbonske pogodbe, ki je od 1. januarja 2009 ustavna podlaga EU.
