THE HAGUE — In its July 2024 Advisory Opinion concerning the Legal Consequences Arising from the Policies and Practices of Israel in the Occupied Palestinian Territory, the International Court of Justice delivered a detailed assessment of the legal limits governing belligerent occupation.
The Court concluded that prolonged occupation, accompanied by permanent infrastructure development and settlement expansion, amounts to unlawful territorial annexation.
1. Temporal Limitations on Belligerent Occupation
Under international humanitarian law—specifically Article 43 of the 1907 Hague Regulations and Article 47 of the Fourth Geneva Convention—belligerent occupation is defined by two core characteristics:
- Provisional Nature: Occupation is a temporary exercise of de facto military authority that confers no sovereign title over the territory.
- Prohibition of Territorial Acquisition: The occupying power cannot alter the legal or demographic status of the occupied land.
The Court determined that permanent settlement construction, the application of domestic legislation to occupied territory, and the exploitation of natural resources violate the prohibition on the acquisition of territory by force under Article 2(4) of the UN Charter. Consequently, the Court found the continuation of the occupation itself to be contrary to international law, requiring cessation and withdrawal.
2. Application of Article 3 of the CERD
The Court evaluated the legal regime in the occupied territory under Article 3 of the International Convention on the Elimination of All Forms of Racial Discrimination (CERD).
The Court observed that the institutionalization of separate legal systems, differential planning rules, and segregated transport infrastructure creates systemic discrimination and separation that breaches the core protections of the convention.
3. Third-State Obligations Erga Omnes
The Court articulated specific legal consequences for all third states:
- Non-Recognition: States must not recognize the illegal situation resulting from the continued presence in the occupied territory.
- Non-Assistance: States are obligated to refrain from providing aid or assistance that maintains the existing situation.
- Trade and Investment Disentanglement: States must prevent trade or investment relationships that treat settlements as legally integrated into the territory of the occupying power.
