The Uniting for Peace resolution, adopted by the United Nations General Assembly on 3 November 1950 as Resolution 377(V)A, established a procedural mechanism by which the Assembly may take up matters of international peace and security when the Security Council, owing to the lack of unanimity among its permanent members, fails to exercise its primary responsibility under Article 24 of the UN Charter. Drafted principally by U.S. Secretary of State Dean Acheson during the Korean War to circumvent anticipated Soviet vetoes after Moscow's return to the Council, the resolution rests on the Assembly's residual competences under Articles 10, 11, and 14 of the Charter — its general authority to discuss and recommend on any matter within the scope of the Charter. The International Court of Justice tacitly endorsed the procedure in its 1962 Certain Expenses advisory opinion, holding that Assembly-authorized peacekeeping expenditures (notably UNEF I) constituted legitimate expenses of the Organization under Article 17(2).
Procedurally, Resolution 377A authorizes the convening of an emergency special session (ESS) within twenty-four hours of a request. The trigger may come from the Security Council itself by a procedural vote of any nine members — a vote to which the veto does not apply, as confirmed by the ICJ — or from a majority of UN member states communicating their request to the Secretary-General. Once convened, the Assembly may consider the matter immediately and issue recommendations to members for collective measures, including, in the case of a breach of the peace or act of aggression, the use of armed force to maintain or restore international peace and security. Recommendations require a two-thirds majority under Article 18(2) when classified as important questions.
The resolution further contemplates standing machinery that has largely fallen into desuetude: a Peace Observation Commission to report on tensions endangering peace, and a recommendation that member states maintain elements within their armed forces designated for prompt UN service. In practice, the operational core that survives is the ESS mechanism itself, governed by Rules 8(b) and 9(b) of the Assembly's Rules of Procedure. ESS sessions are numbered separately from regular and special sessions, may meet at any time, and remain seized of the matter through repeated reconvening — a feature exploited extensively in the case of Palestine.
Eleven emergency special sessions have been convened since 1950. The first followed the Anglo-French-Israeli intervention at Suez in November 1956, producing the authorization for UNEF I, the first armed UN peacekeeping force. The second addressed Soviet intervention in Hungary that same month; subsequent sessions covered Lebanon and Jordan (1958), the Congo (1960), the Six-Day War (1967), Bangladesh (1980), Afghanistan (1980), Namibia (1981), the Israeli-occupied territories (1982), and Bosnia (1992). The Tenth Emergency Special Session, convened in 1997 on the Question of Illegal Israeli Actions in Occupied East Jerusalem and the rest of the Occupied Palestinian Territory, has been repeatedly resumed — including in December 2017 (condemning recognition of Jerusalem as Israel's capital) and remains procedurally open. On 27 February 2022, the Security Council invoked Resolution 377A by a 11-1-3 procedural vote to convene the Eleventh Emergency Special Session on Ukraine; its Resolution ES-11/1 of 2 March 2022 deplored Russian aggression by a vote of 141-5-35.
Uniting for Peace must be distinguished from the regular Assembly agenda and from Security Council Chapter VII enforcement. Unlike binding Council decisions under Article 25, Assembly recommendations under Resolution 377A are not legally binding on member states; they generate political authority, legitimacy, and — crucially — a basis for collective financing and for peacekeeping consent regimes. It is also distinct from the so-called Veto Initiative (Resolution 76/262 of 26 April 2022), which automatically convenes an Assembly debate within ten working days of any P5 veto without requiring a procedural trigger. The two mechanisms now operate in tandem: the Veto Initiative compels explanation; Uniting for Peace enables substantive action.
Controversy persists over the resolution's constitutional pedigree. The Soviet Union and subsequently the Russian Federation have argued that 377A encroaches on Council primacy under Article 12(1), which bars Assembly recommendations on matters the Council is "exercising" its functions over. Subsequent practice — endorsed by the ICJ in its 2004 Wall advisory opinion — has narrowed Article 12 to situations of active Council seizure with substantive measures, permitting parallel Assembly engagement. Western states, initial architects of the mechanism, grew ambivalent after the 1956 Suez precedent turned the procedure against the United Kingdom and France, and again after its sustained use on Palestine. Scholarly debate continues over whether 377A could authorize, as opposed to merely recommend, the use of force — the prevailing view being that it cannot displace Article 42's Council monopoly.
For the working practitioner, Uniting for Peace remains the principal procedural lever for moving a deadlocked file from the Council's 15-member chamber to the Assembly's 193-member plenary, transforming a P5 veto from a terminal block into a political cost. Desk officers drafting ESS resolutions must calibrate text to secure the two-thirds threshold, manage the interaction with any ongoing Council seizure, and anticipate financing implications under Article 17. The 2022 Ukraine precedent confirmed that the mechanism retains operational vitality seventy years after its drafting, and that even permanent members will invoke it against one of their own when the political configuration permits.
Example
On 27 February 2022, the UN Security Council invoked Resolution 377A to convene the Eleventh Emergency Special Session on Ukraine, which on 2 March 2022 adopted Resolution ES-11/1 deploring Russian aggression by 141 votes to 5.
