Rule established

A state exists in international law when it possesses: (1) a defined territory, (2) a permanent population, (3) an effective government, and (4) capacity to enter into relations with other states. These four criteria constitute the declaratory test of statehood.

Facts

  • Deutsche Continental Gas held concessions in Upper Silesia (originally German territory)
  • After WWI, the territory was transferred to Poland
  • Company claimed compensation from the "Polish State"
  • Preliminary question: did Poland exist as a state at the relevant date?

Issue

  1. What constitutes a "state" in international law?

Held

  • A state exists when four criteria are satisfied:
  • A defined territory (need not be precisely delimited; borders may be disputed)
  • A permanent population
  • An effective government exercising control
  • Capacity to enter into relations with other states

Ratio Decidendi

The existence of a state is a question of fact. A community constitutes a state when it possesses a defined territory, a permanent population, an effective government, and the capacity to conduct foreign relations. Recognition by other states is declaratory, not constitutive, of statehood.

How to use it in an exam

  • Authority for the four criteria of statehood (pre-Montevideo formulation)
  • Always paired with Montevideo Convention 1933, Art. 1
  • Key line: "In Deutsche Continental Gas v. Polish State (1929), the Tribunal held that a state exists when it possesses: (1) defined territory, (2) permanent population, (3) effective government, and (4) capacity to enter into foreign relations."
