Legal Status of Eastern Greenland (Denmark v Norway)
Rule established
A claim to sovereignty requires intention and will to act as sovereign together with actual exercise of authority; in thinly populated or uninhabited territories, modest acts of administration suffice.
Facts
- Denmark claimed sovereignty over the entirety of Greenland, including the uninhabited eastern coast
- In 1931, Norway proclaimed sovereignty over parts of Eastern Greenland
- Denmark relied on centuries of legislative and administrative acts extending to all of Greenland
- Denmark also relied on the Ihlen Declaration (1919), in which Norway's Foreign Minister stated that Norway would not contest Danish sovereignty over Greenland
- Norway argued that Danish occupation was insufficient over the vast, uninhabited eastern territory
Issue
- Whether Denmark had established a valid title to Eastern Greenland through effective occupation, and whether the Ihlen Declaration constituted a binding unilateral commitment by Norway.
Held
- The PCIJ upheld Danish sovereignty over all of Greenland
- Effective occupation requires intention to act as sovereign (animus) plus actual exercise of authority (corpus)
- In uninhabited or thinly populated territories, modest acts of administration satisfy the corpus requirement
- Denmark's legislation, licensing, and occasional patrols were sufficient
- The Ihlen Declaration was binding as a unilateral statement by a competent state official acting within his authority
Ratio Decidendi
A claim to territorial sovereignty is established by showing the intention and will to act as sovereign (animus possidendi) combined with some actual exercise or display of such authority (corpus). The degree of authority required varies with the nature of the territory: in remote, uninhabited areas, relatively modest acts suffice. Additionally, a unilateral declaration by a Foreign Minister, made within the scope of his authority, creates a binding legal obligation on the state.
How to use it in an exam
- Two rules in one case: (1) minimal-activity standard for effective occupation in uninhabited territory; (2) binding force of unilateral declarations
- Deploy in Part A for animus + corpus formula and in Part C for problem questions on competing claims
- Pair with Island of Palmas (1928) for the full effective occupation analysis
- Key line: "A claim to sovereignty based not upon some particular act or title but merely upon continued display of authority involves two elements: the intention and will to act as sovereign, and some actual exercise or display of such authority."
