Definition

In plain language

According to this theory, a country becomes a State when it actually meets the conditions for statehood, such as territory and government, and other States' recognition only acknowledges that fact.

Academic definition

The declaratory theory holds that the existence of a State is a question of fact, and recognition has only declaratory value. Article 3 of the 1933 Montevideo Convention states that the political existence of the State is independent of recognition, and the Badinter Arbitration Commission's Opinion 1 (1991) said that the existence or disappearance of a State is a question of fact and that recognition by other States has purely declaratory value. The opposing constitutive theory, associated with earlier writers such as Oppenheim, holds that recognition creates statehood and has been criticised for making legal status depend on political choices.

Context

Legal effect: Informational

Scope

Covers the theory about the effect of recognition; the acts of recognition themselves are in the 'De Jure Recognition' and 'Recognition of State' records.

Legal context

Montevideo Convention Article 3 and Article 6; Charter of the Organization of American States Article 13 (1948) stating that the political existence of the State is independent of recognition by other States; Badinter Opinion 1 (1991). Even under the declaratory view, non-recognition may affect practical dealings and collective non-recognition may arise from breaches of peremptory norms.

Diplomatic context

States cite the theory to argue that entities exist whether or not others recognise them, while opponents invoke political non-recognition, as in disputes over unrecognised States.

Institutional context

Applied by courts and arbitral bodies such as the Badinter Commission, and discussed in the ILC and foreign ministries.

Historical context

The constitutive view dominated in the nineteenth century, and the declaratory view became dominant after Montevideo in 1933 and the Badinter opinions in 1991.

Why it matters

The theory matters for entities not widely recognised, which may still bear duties, such as the prohibition of force, if they meet the criteria for statehood.

Usage

Register: Academic

Usage note

Pair the term with 'constitutive theory' when explaining; the two are opposites.

Example

Under the declaratory theory, the entity was already a State when it met the criteria, regardless of recognition.

Example scenario

A territory declares independence and is recognised by only a few States. A court applying the declaratory theory asks whether it has a population, territory, effective government and capacity to enter relations, and does not treat the lack of wider recognition as decisive.

Common misuse

Reading it as saying recognition is meaningless; it still has political and practical consequences.

Not to be confused with

  • Constitutive theory of recognition
  • De jure recognition
  • Admission to UN membership
