  • 3 October 2005: Accession negotiations opened with Turkey.

Discussions are conducted on the basis of a “negotiation framework” which specifies that “these negotiations are an open-ended process, the outcome of which cannot be guaranteed beforehand. While taking account of all Copenhagen criteria, including the capacity of the Union to accept new members, if Turkey is not in a position to assume in full all the obligations of membership, it must be ensured that Turkey is fully anchored in the European structures through the strongest possible bond.”

The Commission will monitor the capacity of the EU to take on this new Member State during the negotiations, to enable the EU to assess whether this accession condition has been met.

The negotiations will be governed entirely by the principle of unanimity, which means that any State may, at any time, make itself heard. Conditions for closing, and, if necessary, opening negotiations on the 35 chapters will be defined by the EU unanimously: these conditions will in particular concern the alignment of Turkish legislation with the Community acquis, the implementation of this legislation throughout the entire territory, and Turkey’s compliance with its obligations to the EU. Specific provisions, including permanent safeguard clauses, may be stipulated. Finally, in the event of gross and persistent violation of human rights and civil liberties, a negotiation suspension mechanism has been included in the negotiation framework.

The European Union continues to monitor the progress made in the issues opened by the declaration of 21 September 2005.
