To join the European Union, a state needs to fulfil economic and political conditions called the Copenhagen criteria

, membership of the European Union is open to "any European State which respects the values referred to in Article 2 and is committed to promoting them" (TEU Article 49). Those Article 2 values are "respect for human dignity, freedom, democracy, equality, the rule of law and respect for human rights, including the rights of persons belonging to minorities."

 countries would apply to join;
In December 1995, the Madrid European Council revised the membership criteria to include conditions for member country integration through the appropriate adjustment of its administrative structures: since it is important that European Community legislation be reflected in national legislation, it is critical that the revised national legislation be implemented effectively through appropriate administrative and judicial structures.

Finally, and technically outside the Copenhagen criteria, comes the further requirement that all prospective members must enact legislation in order to bring their laws into line with the body of European law built up over the history of the Union, known as the acquis communautaire.

Process

Today the accession process follows a series of formal steps, from a pre-accession agreement to the ratification of the final accession treaty. These steps are primarily presided over by the European Commission (Enlargement Commissioner and DG Enlargement
Directorate-General for Enlargement (European Commission)

), but the actual negotiations are technically conducted between the Union's Member States and the candidate country.

Before a country applies for membership it typically signs an association agreement to help prepare the country for candidacy and eventual membership. Most countries do not meet the criteria to even begin negotiations before they apply, so they need many years to prepare for the process. An association agreement helps prepare for this first step.

In the case of the Western Balkans, a special process, the Stabilisation and Association Process

 exists to deal with the special circumstances there.

When a country formally applies for membership, the Council asks the Commission to prepare an opinion on the country's readiness to begin negotiations. The Council can then either accept or reject the Commission's opinion (The Council has only once rejected the Commission's opinion when the latter advised against opening negotiations with Greece).

If the Council agrees to open negotiations the screening process then begins. The Commission and candidate country examine its laws and those of the EU and determine what differences exist. The Council then recommends opening negotiations on "chapters" of law that it feels there is sufficient common ground to have constructive negotiations. Negotiations are typically a matter of the candidate country convincing the EU that its laws and administrative capacity are sufficient to execute European law, which can be implemented as seen fit by the member states. Often this will involve time-lines before the Acquis Communautaire (European regulations, directives & standards) has to be fully implemented.

A chapter is said to be closed when both sides have agreed it has been implemented sufficiently, however it can still be re-opened if the Commission feels that the candidate has fallen out of compliance.

European Council
The European Council is an institution of the European Union. It comprises the heads of state or government of the EU member states, along with the President of the European Commission and the President of the European Council, currently Herman Van Rompuy...

. These serve as a basis for the Council to make decisions on negotiations or their extension to other candidates.

Once the negotiations are complete a treaty of accession will be signed, which must then be ratified by all of the member states of the Union, as well as the institutions of the Union, and the candidate country. Once this has been completed it will join the Union on the date specified in the treaty.

The entire process, from application for membership to membership has typically taken about a decade, although some countries, notably Sweden, Finland, and Austria have been faster, taking only a few years. The process from application for association agreement through accession has taken far longer, as much as several decades (Turkey for example first applied for association in the 1950s and has yet to conclude accession negotiations).

Example

The following is an example of an accession process. This follows Estonia's journey to membership, as a recent example from the 2004 enlargement, however the speed of accession depends on each state: how integrated it is with the EU before hand, the state of its economy and public institutions, any outstanding political issues with the EU and (historically) how much law to date the EU has built up that the acceding state must adopt. This outline also includes integration steps taken by the accession country after it attains membership.

 opposed Greek, Spanish and Portuguese membership fearing they were not ready and it would water the community down to a free trade area.

The reasons for the first member states to apply, and for them to be accepted, were primarily economic while the second enlargement was more political. The southern Mediterranean countries had just emerged from dictatorships and wanted to secure their democratic systems through the EEC, while the EEC wanted to ensure the same thing and that their southern neighbours were stable and aligned to NATO. These two principle forces, economic gain and political security, have been behind enlargements since. However, with the recent large enlargements in 2004, public opinion in Europe has turned against further expansion.

It has also been acknowledged that enlargement has its limits, the EU cannot expand endlessly. Former Commission President

n sphere of influence. The EU, and NATO, offered a guarantee of this and the EU was also seen as vital to ensuring the economic success of those countries. The EU's desire to accept these countries' membership applications was however less than rapid. The collapse of communism came quickly and was not anticipated. The EU struggled to deal with the sudden reunification of Germany with the addition of its poorer 17 million people and, while keeping its monetary union project on track, it was still at that early stage pointing the EFTA countries in the direction of the EEA rather than full membership.

The former communist states persisted and eventually the above mentioned issues were cleared. The US also pressured the EU to offer membership as a temporary guarantee; it feared expanding NATO too rapidly for fear of frightening Russia. Although eventually trying to limit the number of members, and after encouragement from the US, the EU pursued talks with ten countries and a change of mind from Cyprus

) were able to join on 1 May 2004. This was the largest single enlargement in terms of people, and number of countries, though not in terms of GDP. The less developed nature of these countries was of concern to some of the older member states, who placed temporary restrictions on the rights of work of the citizens of these new eastern states to their countries. The movement westward of some of the labour force of the newly acceded countries that occurred in the aftermath of the enlargement initially spawned clichés among the public opinion and media of some western countries (such as the "Polish plumber

"), despite the generally conceded benefit to the economies concerned. The official EU media (the speeches of the European Commission) frequently referred to the enlargement to the CEE region as "an historical opportunity" and "morally imperative", which reflected the desire of the EU to admit these countries as members, even though they were less developed than the Western European countries.
