The member states of the European Union and the candidates for
membership agreed in Copenhagen on 13 December 2002 on a package
for the admission of ten new member states to the Union. The accession
treaty was signed in Athens on April 16th 2003, and these
new member states will join the EU on 1 May 2004, once the accession
treaty is ratified.
No popular referenda are foreseen in the existing member states
of the European Union on the accession treaty. Ratification follows
the constitutional procedure in each member state.
Ratification in 9 of the 10 acceding countries follows popular
referenda (see below ). Cyprus ratified the treaty according to
its domestic procedures on 14th July 2003.
