The consultation process and Article 4
All NATO decisions are made by consensus, after discussion and consultation among member countries. Consultation between member states is therefore at the heart of NATO since Allies are able to exchange views and information, and discuss issues prior to reaching agreement and taking action.
- Consultation is a key part of NATO’s decision-making process since all decisions are made by consensus.
- It takes place on all subjects of interest to the Alliance, including NATO’s day-to-day business, its core objectives and fundamental role.
- Consultation reinforces NATO’s political dimension by giving members the opportunity to voice opinions and official positions. It also gives NATO an active role in preventive diplomacy by providing the means to help avoid military conflict.
- In Article 4 of NATO’s founding treaty, members can bring any issue of concern, especially related to the security of a member country, to the table for discussion within the North Atlantic Council.
- Since the Alliance’s creation in 1949, Article 4 has been invoked several times, for instance by Türkiye.
Consultation takes many forms. At its most basic level it involves simply the exchange of information and opinions. At another level it covers the communication of actions or decisions, which governments have already taken or may be about to take. Finally, it can encompass discussion with the aim of reaching a consensus on policies to be adopted or actions to be taken.
In sum, consultation is continuous and takes place both on a formal and informal basis. It can happen quickly due to the fact that all member states have permanent delegations at NATO Headquarters in Brussels. Governments can come together at short notice whenever necessary, often with prior knowledge of their respective national preoccupations, in order to agree on common policies or take action on the basis of consensus. NATO’s network of committees facilitates consultation by enabling government officials, experts and administrators to come together on a daily basis to discuss a broad range issues.
The principle of consensus decision-making is applied throughout NATO, which means that all “NATO decisions” are the expression of the collective will of all sovereign states that are members of this inter-governmental organisation. While consensus decision-making can help a member country preserve national sovereignty in the area of defence and security, Article 4 can be an invitation for member countries to concede this right to the group or it can simply lead to a request for NATO support.
Under Article 4 of NATO’s founding treaty, member countries can bring an issue to the attention of the North Atlantic Council (Council or NAC – NATO’s principal political decision-making body) and discuss it with Allies. The article states:
“The Parties will consult together whenever, in the opinion of any of them, the territorial integrity, political independence or security of any of the Parties is threatened.”
Any member country can formally invoke Article 4 of the North Atlantic Treaty. As soon as it is invoked, the issue is discussed and can potentially lead to some form of joint decision or action on behalf of the Alliance. Whatever the scenario, fellow members sitting around the Council table are encouraged to react to a situation brought to their attention by a member country.
Since the Alliance’s creation in 1949, Article 4 has been invoked seven times. On 24 February 2022, Bulgaria, the Czech Republic, Estonia, Latvia, Lithuania, Poland, Romania and Slovakia requested to hold consultations under Article 4 following the Russian invasion of Ukraine.
On 26 July 2015, Türkiye made the same request in view of the seriousness of the situation following terrorist attacks, and to inform Allies of the measures it was taking. Poland invoked Article 4 on 3 March 2014 following increasing tensions in neighbouring Ukraine, as a result of Russia’s aggressive actions. On two occasions in 2012, Türkiye requested a NAC meeting under Article 4: once on 22 June after one of its fighter jets was shot down by Syrian air defence forces and the second time on 3 October when five Turkish civilians were killed by Syrian shells. Following these incidents, on 21 November, Türkiye requested the deployment of Patriot missiles. NATO agreed to this defensive measure so as to help Türkiye defend its population and territory, and help de-escalate the crisis along the border.
Previously, on 10 February 2003, Türkiye formally invoked Article 4, asking for consultations in the NAC on defensive assistance from NATO in the event of a threat to its population or territory resulting from armed conflict in neighbouring Iraq. NATO agreed a package of defensive measures and conducted Operation Display Deterrence from end February to early May 2003.
The political dimension of NATO
Encouraging members of an inter-governmental organisation who have not given up their right of free and independent judgment in international affairs to consult more systematically on an issue is a challenge – be it today or in the 1950s.
In the early 1950s, the NAC recognised NATO’s consultative deficiency on international issues and recommended that measures be taken to improve the process. In April 1954, a resolution on political consultation was adopted:
“... all member governments should bear constantly in mind the desirability of bringing to the attention of the Council information on international political developments whenever they are of concern to other members of the Council or to the Organization as a whole; and (...) the Council in permanent session should from time to time consider what specific subject might be suitable for political consultation at one of its subsequent meetings when its members should be in a position to express the views of their governments on the subject.” C-M(54)38.
The resolution, which was put forward by Canada and immediately approved, provoked nonetheless a reaction from the American representative:
“Mr. Dulles (United States) supported the Canadian resolution on the understanding that consultation would be limited within the bounds of common sense. Countries like his own with world-wide interests might find it difficult to consult other NATO governments in every case. For a sudden emergency, it was more important to take action than to discuss the emergency. In other words, consultation should be regarded as a means to an end, rather than an end in itself.” (C-R(54)18).
The reservations made by the United States, which no doubt were shared by other member countries, could still be voiced today. Building on this resolution, on 8 March 1956, the then Secretary General of NATO, Lord Ismay, made a statement which widened the debate by explaining the consequences of systemising political consultation within the Alliance:
“A direct method of bringing home to public opinion the importance of the habit of political consultation within NATO may be summed up in the proposition “NATO is a political as well as a military alliance”. The habitual use of this phraseology would be preferable to the current tendency to refer to NATO as a (purely) military alliance. It is also more accurate. To refer to NATO as a political alliance in no sense denies, depreciates or deprecates the fact that the alliance is also military.” (C-M(56)25-1956).
The same year, the “Three Wise Men” produced their report, which inter alia sought to improve consultation within the Alliance on issues of common concern (“Report of the Committee of Three on Non-Military Cooperation in NATO”). However, ironically it was published as the Suez crisis emerged. Suez severely divided the leading founding members of the Organization (France, the United Kingdom and the United States). The Suez crisis acted as a catalyst for NATO, leading it to put into practice something it knew was of vital importance for the unity and solidarity of the Alliance – political consultation.
“Animus in consulendo liber”
For its anecdotal value, it is worth noting that when NATO moved to its headquarters at the Porte Dauphine in Paris, in December 1959, the then Secretary General, M. Paul-Henri Spaak, enlisted the help of the Dean of the Council in finding a suitable Latin maxim which would capture the spirit of consultation between Allies to which he attached so much importance. The Dean, Belgian Ambassador André de Staercke, recalled a visit he had made to the Tuscan town of San Gimignano. There, in the Palazzo del Podestà, engraved on the back of the seat reserved for the man who presided over the destinies of the city, he had seen the motto: Animus in consulendo liber.
It seems that an entirely satisfactory translation of the phrase cannot be found, although a French version “l’esprit libre dans la consultation” comes close. Renderings in English have ranged from the cryptic “in discussion a free mind” to the more complex “Man’s mind ranges unrestrained in counsel”.
The motto adorned the conference area at the Porte de Dauphine for several years and, in 1967, was moved to NATO’s
As explained above, consultation and consensus were accepted as the basis for all NATO decisions when the Alliance was created in 1949.
However, it was only gradually that NATO set up a consultation system. In broad terms, this was done in three stages:
- 1949-1952: at the signing of the Treaty, NATO introduced the consultation process as a key principle in its working mechanisms. This was reinforced at the Lisbon Conference (1952) where the contours of today’s NATO were put into place: the NAC was made permanent and the position of Secretary General was created, together with an international staff that would support Council decisions on a permanent basis;
- 1952-1956: between 1952 and the publishing of the Committee of Three report on non-military cooperation, attempts had been made to encourage political consultation beyond the geographical limitations defined in the founding treaty, i.e, beyond the defined NATO area.
- From 1956: the principles of the Report of the Committee of Three were further developed and implemented. The Committee recommended measures in the area of political cooperation with regard to foreign policies, the peaceful settlement of inter-member disputes, economic cooperation, scientific and technical cooperation, cultural cooperation and cooperation in the information field.
The Committee of Three left a lasting legacy by encouraging NATO members to reconcile differences within the Organization through productive consultation on matters of common concern, including issues outside the defined NATO area. The Suez crisis provided a first-hand example of why close political consultation and non-military cooperation are necessary.
The principal forum for political consultation is the North Atlantic Council. The NAC is NATO’s principal political decision-making committee. The Secretary General, by virtue of his chairmanship, plays an essential part in this process. Consultation also takes place on a regular basis in other fora, including NATO committees and working groups. All of these bodies derive their authority from the Council.
