Current opt-outs

Economic and Monetary Union stage III (Eurozone) – Denmark

All member states other than Denmark have either adopted the euro or are legally bound to do so. The

giving them opt-outs with the right to decide if and when they would join the euro. Denmark subsequently notified the Council of the European Communities of their decision to opt out of the euro, and this was included as part of the 1992 Edinburgh Agreement, a Decision of Council, reached following the Maastricht Treaty's initial rejection in a 1992 Danish referendum. The purpose of the agreement was to assist in its approval in a second referendum, which it did. The Danish decision to opt out was subsequently formalized in an amended protocol as part of the

Area of freedom, security and justice

Denmark and Ireland have opt-outs from the area of freedom, security and justice in general, while Poland has a partial opt-out from enforcement of the Charter of Fundamental Rights only. The United Kingdom also had opt-outs in all these policies prior to its

However, the protocol on the Schengen acquis specified that they could request to opt into participating in Schengen measures on a case-by-case basis if they wished, subject to unanimous approval of the other participating states.

Prior to the renewal of the CTA in 2011, when the British government was proposing that passports be required for Irish citizens to enter the UK, there were calls for Ireland to join the Schengen Area.

Denmark

In contrast, Denmark has a more rigid opt-out from the area of freedom, security and justice. While the Edinburgh Agreement of 1992 stipulated that "Denmark will participate fully in cooperation on Justice and Home Affairs", the Treaty of Amsterdam of 1997 included a
protocol Protocol may refer to: Sociology and politics * Protocol (politics), a formal agreement between nation states * Protocol (diplomacy), the etiquette of diplomacy and affairs of state * Etiquette, a code of personal behavior Science and technolog ...
which exempts it, as a matter of EU law, from participating in these policy areas, which are instead conducted on an intergovernmental basis with Denmark. The protocol on the Schengen acquis and protocol on Denmark of the Treaty of Amsterdam stipulate that

pillar, from which Denmark obtained an opt-out. When a measure is adopted which builds upon the Schengen acquis, Denmark has six months to decide whether to implement it. If Denmark decides to implement the measure, it takes the force of an international agreement between Denmark and the Schengen states. However, the protocol stipulates that if Denmark chooses not to implement future developments of the Schengen acquis, the EU and its member states "will consider appropriate measures to be taken". The exception is the Schengen visa rules. A failure by Denmark to implement a Schengen measure could result in it being excluded from the Schengen Area. A number of other parallel intergovernmental agreements have been concluded between the EU and Denmark to extend to it EU Regulations adopted under the area of freedom, security and justice, which Denmark can't participate in directly due to its opt-out. In the negotiations of the Lisbon Treaty, Denmark obtained an amendment to the

to give it the option to convert its opt-out into a flexible opt-in modelled on the Irish and British opt-outs. The Protocol stipulates that if Denmark exercises this option, then it will be bound by the Schengen acquis under EU law rather than on an intergovernmental basis. In a referendum on 3 December 2015, 53.1% rejected exercising of this option.

Summary table


Legal guarantees

Several times an EU member state has faced domestic public opposition to the ratification of an EU treaty leading to its rejection in a referendum. To help address the concerns raised, the EU has offered to make a "legal guarantee" to the rejecting state. These guarantees did not purport to exempt the state from any treaty provisions, as an opt-out does. Instead they offered a clarification or interpretation of the provisions to allay fears of alternative interpretations.

Irish protocol on the Lisbon Treaty

Following the rejection of the Treaty of Lisbon by the Irish electorate in 2008, a number of guarantees (on security and defence, ethical issues and taxation) were given to the Irish in return for holding a second referendum. On the second attempt in 2009 the treaty was approved. Rather than repeat the ratification procedure, the guarantees were merely declarations with a promise to append them to the next treaty.Crosbie, Judith (12 May 2009
