In brief

Recognition is the formal or implied acknowledgement by one State of the existence of another State, a government, or a situation (belligerency, insurgency, territorial change), with willingness to treat it as having the legal consequences of that status. It is political in motive but legal in effect.
In brief
Covers Montevideo Art 3, Problem with the constitutive theory.
| Theory | Core idea | Proponents |
|---|---|---|
| Constitutive | Recognition creates statehood; an entity becomes an international person only through recognition | Hegel, Oppenheim, Anzilotti; Lauterpacht (qualified – duty to recognise once criteria met) |
| Declaratory (evidentiary) | Statehood exists once Montevideo criteria are fulfilled; recognition merely acknowledges it | Hall, Brierly, Montevideo Convention Art 3, OAS Charter |
Montevideo Art 3: ‘The political existence of the State is independent of recognition by the other States.’
Modern practice favours the declaratory theory with elements of collective legitimisation (e.g., UN admission as strong evidence).
Problem with the constitutive theory: a State recognised by some but not others – is it a State or not?
In brief
Covers De facto vs de jure, Express vs implied, Individual vs collective, Conditional recognition, Recognition of belligerency and more.
De facto vs de jure: de facto = provisional, based on effective control but doubts about permanence; de jure = full, final recognition. Luther v Sagor (1921, UK) – Soviet government.
Express vs implied (e.g., exchange of ambassadors, bilateral treaties; mere participation in a multilateral conference or UN voting does not imply recognition).
Individual vs collective.
Conditional recognition – e.g., European Community Guidelines 1991 and Badinter Commission on Yugoslavia.
Recognition of belligerency – civil war with control of territory; insurgency is a lesser status.
Retroactive effect: de jure recognition relates back to the date of de facto recognition.
Withdrawal of recognition is mainly possible for de facto governments.
In brief
Covers Tobar Doctrine (1907), Estrada Doctrine (1930, Mexico), Stimson Doctrine (1932), Hallstein Doctrine (West Germany, 1955), Wilson Doctrine and more.
Tobar Doctrine (1907): refuse recognition to governments that come to power by unconstitutional means.
Estrada Doctrine (1930, Mexico): no declarations of recognition of governments; merely continue or withdraw diplomatic agents.
Stimson Doctrine (1932): non-recognition of territorial changes obtained by force (Japan in Manchuria). Reflected in the Friendly Relations Declaration (1970) and the Wall AO (2004).
Hallstein Doctrine (West Germany, 1955): no relations with States recognising East Germany.
Wilson Doctrine: recognition on basis of constitutional legitimacy.
Collective non-recognition: UNSC Res 276 (1970) on Namibia; Res 541 (1983) on Northern Cyprus (recognised only by Turkey); Southern Rhodesia (Res 216, 217 of 1965).
In brief
Tests: effective control, popular acquiescence, willingness to observe international obligations.
Tests: effective control, popular acquiescence, willingness to observe international obligations. Tinoco Arbitration (Great Britain v Costa Rica, 1923) – non-recognition by Britain did not defeat the de facto effectiveness of the Tinoco government. The UK stopped formally recognising governments in 1980. Legal effects include sovereign immunity, standing in domestic courts, title to State property and diplomatic privileges.
In brief
Covers Kosovo, Palestine, Taliban government (Afghanistan), Self-determination and secession.
Kosovo: declared independence 17 Feb 2008; ICJ AO (22 July 2010) – declaration of independence did not violate general international law or UNSC Res 1244.
Palestine: UNGA Resolution 67/19 (29 Nov 2012) granted ‘non-member observer State’ status; enhanced rights in May 2024 (UNGA ES-10/23) while full UN membership was blocked by a US veto in UNSC (April 2024). Spain, Ireland and Norway recognised Palestine in 2024; in September 2025 a further group (including UK, France, Canada, Australia, Portugal) recognised it. India recognised Palestine in 1988.
Taiwan, Western Sahara, Northern Cyprus, Abkhazia/South Ossetia, Crimea: classic examples of limited recognition.
Taliban government (Afghanistan): de facto control since Aug 2021; Russia formally recognised it in July 2025 – a recent ‘recognition of government’ example.
Self-determination and secession: Western Sahara AO (1975); Quebec Secession Reference (Canada, 1998); Chagos Archipelago AO (2019) – UK’s continued administration unlawful; UK–Mauritius treaty (2025) on sovereignty with Diego Garcia base arrangements.
In brief
Covers Continuity vs succession, Clean slate.
Types: universal vs partial; merger, dissolution, secession, cession, decolonisation (‘newly independent State’ – clean slate).
Vienna Convention on Succession of States in respect of Treaties 1978 (in force 1996) and Vienna Convention on Succession of States in respect of State Property, Archives and Debts 1983 (not in force).
Continuity vs succession: India was treated as the continuing State of British India (retained UN membership); Pakistan was a new State. Russia continued the USSR’s UN seat in 1991.
Clean slate doctrine (Nyerere’s ‘Tanganyika formula’); devolution agreements.
