The Obligation of Non-recognition, Occupation and the OPT Advisory Opinion

In the OPT Advisory Opinion, the ICJ considered that Israel’s abuse of its position as an Occupying Power, through de jure and de facto annexation of the Occupied Palestinian Territory (OPT) and continued frustration of the right of the Palestinian people to self-determination, renders Israel’s presence in the OPT unlawful. In determining the legal consequences of this illegal presence, the Court held by a vote of 12:3, that all States are under an obligation “not to recognize as legal the situation arising from the unlawful presence of the State Israel in the Occupied Palestinian Territory”. This holding was not accompanied by any concretization in either the Advisory Opinion or any of the many declarations and separate opinions attached to it.

Security Considerations, the Duty to End Belligerent Occupations and the ICJ Advisory Opinion on Israeli practices and policies in the Occupied Palestinian Territory

This contribution discusses three possible rationales for the Court’s rejection of the relevance of Israel’s security concerns: Lack of proof of serious and legitimate security concerns by Israel, the insufficiency of broad security concerns to justify the continued use of force, and the insufficiency of broad security concerns to deny realization of Palestinian self-determination. As long as international law doctrine on the duty to end a belligerent occupation despite the prevalence of serious security concerns remains contested, and as long as security conditions in the region remain extremely unstable, it is unlikely that a withdrawal will be deemed practicable

The ICJ’s Treatment of Questions of Occupation in Gaza

The ICJ’s treatment of the state of occupation in Gaza is questionable. While it rightly accepted the functional approach to occupation, I doubt whether Israel was indeed capable of exercising its authority in Gaza sufficiently for its occupation to be found as having continued post-2005. The Court should have relied on Israel’s continued exercise of administrative authority vis-a-vis Gaza residents to find the existence of a state of occupation.

The Functional Approach as Lex Lata

The ICJ has de facto adopted the functional approach to occupation with regard to Gaza. The Opinion is thus a critical point in the development of the law of occupation, in that it transcends a binary approach to the question of the existence of occupation, in favour of a more nuanced approach that enables holding that a territory is occupied, but not in an “all or nothing” way. More generally, the Opinion as rejects a more restrictive approach to the question of whether occupation exists in a territory or not in favour of a more flexible approach.

The Advisory Opinion on Israel’s Policies and Practices in the Occupied Palestinian Territory

This post analyses the separation between jus ad bellum / in bello as arising from the Advisory Opinion of the ICJ. This separation was challenged by many States appearing before the Court, some of which implied that Israel’s policies and practices, as violations of jus in bello, rendered the occupation unlawful under jus ad bellum. The Court ultimately reaffirmed the separation with a twofold argument, namely qualifying the ‘legality of the occupation’ as a jus ad bellum question, and framing Israel’s policies and practices (prolonged occupation, annexation, and settlement policy) as violations of jus ad bellum.

From Illegal Annexation to Illegal Occupation: The Missing Link in the Reasoning of the International Court of Justice

The Court’s determination that Israel’s annexation policies render its continued presence in the West Bank unlawful finds no basis in the international prohibition against the use of force. Moreover, the Court’s determination circumvents the Law of State Responsibility that determines the consequences of Israel’s unlawful annexation policies.

A Seismic Change

It is no understatement to say that the 19 July 2024 ICJ Advisory Opinion constitutes a seismic change in the international law and practice on the question of Palestine. In one fell swoop, the ICJ has shifted what was hitherto an almost exclusive focus of the international community on how Israel has administered its 57-year occupation of the Occupied Palestinian Territory under International Humanitarian Law and International Human Rights Law, to the requirement that Israel end its occupation of that territory as “rapidly as possible”.

The principle of uti possidetis juris and the borders of Israel

The principle uti possidetis juris, raised in the Dissenting Opinion of Vice-President Sebutinde and according to which a new State established in formerly colonial territory inherits the former (colonial) borders is untenable in the situation of Israel. The reason is that at the time of independence Israel’s leaders accepted the principle of partition. No claim was made then or subsequently that the State of Israel inherited the borders of Mandatory Palestine and legislative acts reveal that Israel even regarded territories not within the UN Partition Plan borders as occupied territory.

The 2024 ICJ Advisory Opinion on the Occupied Palestinian Territory – An Introduction

The Advisory Opinion of the International Court of Justice (ICJ) on the "Legal Consequences arising from the Policies and Practices of Israel in the Occupied Palestinian Territory, including East Jerusalem" was a groundbreaking moment in international law. It has consequences not only for Israel, but also for third States, as well as international and regional organizations, in terms of non-recognition and non-cooperation. In this blog symposium, Palestinian, Israeli, and other scholars take stock of the Advisory Opinion and its regional and global impact.
