On November 20, 2013, it was announced that an extension agreement had been reached. The text was signed on 20 December 2013 and, after its signing in April 2014, the agreement will be applied provisionally until it is ratified by Croatia, all EEA states and the European Union.    Since September 2020, the convention has been ratified by 19 out of 32 parties.  However, this agreement had some limitations. There would be no customs union between the EEC and EFTA, as the free movement of goods from EFTA countries would only apply to goods originating in EFTA countries and border controls would continue to avoid relocation. The enlargement of the internal market had not yet been completed. For example, the free movement of persons applies only to workers and not to the general population. The agreement did not provide for harmonization of taxation. The EEA did not cover all areas of activity in the EU; the Common Agricultural Policy, the introduction of the single currency, the common foreign and security policy and police and judicial cooperation were not included in the agreement. However, it provided for close cooperation in the areas of research, the environment and working conditions.
The management of the agreement should be carried out by common bodies. When a state joins the EU, it does not necessarily immediately become a member of the EEA, but must apply.  Following the enlargement of the European UNION in 2007, to which Bulgaria and Romania joined on 1 January 2007, an EEA enlargement agreement was not signed until 25 July 2007 and did not enter into force provisionally until 1 August 2007.    The agreement did not enter into full force until November 9, 2011.  On the other hand, the EEA agreement was provisionally applied to the ten candidate countries in May 2004, from their accession to the EU.  Customs authorities grant the following facilities to an approved economic operator: the contracting parties undertake to keep each other informed in the context of work carried out in the context of international organisations and in the context of intellectual property agreements. the initial plan for the EEA has been lacking in the EFTA Court of Justice or the EFTA Supervisory Authority, given that the “EEA Tribunal” (composed of five members of the European Court of Justice and three members of EFTA countries and which would be functionally integrated into the ECJ) and the European Commission should carry out these tasks. However, during the negotiations on the EEA agreement, the European Court of Justice informed the Council of the European Union (Opinion 1/91) that an EEA jurisdiction over EU law, which was part of EEA law, would constitute a treaty violation, and the current regime was therefore developed.
