Definition

In plain language

A de facto government is one that actually runs a country, for example after a coup, even if others question whether it came to power lawfully.

Academic definition

A de facto government holds effective control of territory and the machinery of State, whatever the legality of how it came to power. In the Tinoco Arbitration (Great Britain v. Costa Rica, 1923), sole arbitrator Taft held that the Tinoco regime's acts bound Costa Rica because it was in actual control, even though Britain had not recognised it. The approach reflects the effectiveness principle, which gives weight to actual control, though many States now frame recognition and credentials decisions in terms of legitimacy and, in some cases, democratic standards.

Context

Legal effect: Context-Dependent

Scope

Covers governments in effective control without full legal title; a government with legal title but not control is a 'de jure government', and recognition acts are treated in separate records.

Legal context

No treaty regulates the matter; general international law, as applied in the Tinoco Arbitration (1923), attributes the acts of an effective government to the State. UN credentials decisions are made by the Credentials Committee and General Assembly.

Diplomatic context

States decide whether to deal with a regime in practice, often maintaining working contacts without formal recognition, and credentials disputes at the UN reveal divided positions.

Institutional context

Foreign ministries, the UN Credentials Committee and courts that decide whether a regime's acts or immunities are recognised.

Historical context

The distinction became important with revolutions and coups in the nineteenth and twentieth centuries, and many States moved toward dealing with governments without formally recognising them.

Why it matters

Whether a regime counts as the government decides who may sign treaties, control assets and represent the State abroad.

Usage

Register: Legal

Usage note

'De facto' means 'in fact'; write it in italics or roman consistently with the house style.

Example

The military council was treated as the de facto government because it controlled the capital and the army.

Example scenario

After a coup in State A, the new regime controls the capital and the army. Several States continue to do business with it without formally recognising it, while others condemn the coup and keep contact with the ousted leaders.

Common misuse

Equating a de facto government with an illegitimate or unrecognised one; the term only indicates effective control.

Not to be confused with

  • De jure government
  • De facto recognition
  • Government in exile
