Executive summary

The UN’s position that Israel’s presence in territories occupied since 1967 is unlawful rests chiefly on the International Court of Justice’s 19 July 2024 advisory opinion finding that “Israel’s continued presence in the Occupied Palestinian Territory is unlawful” and calling for it to end “as rapidly as possible” [1] [2]. The UN General Assembly and draft resolutions have echoed the ICJ’s findings and repeatedly called for withdrawal and compliance with international humanitarian law and prohibitions on settlement expansion [1] [3].

1. How the UN’s legal claim is framed: the ICJ advisory opinion as focal evidence

The General Assembly and UN bodies base the claim of illegality primarily on the ICJ advisory opinion issued in July 2024, which concluded that Israel’s presence in the Occupied Palestinian Territory is “unlawful” and should be brought to an end, citing settlement-building, annexatory legislation and discriminatory measures as central factors [2] [1]. UN draft resolutions and committee texts explicitly recall and rely on that advisory opinion when demanding that Israel comply with obligations to cease settlement activity and end its presence [1].

2. Article 80 and competing readings: preservation vs. termination of Mandate rights

Article 80 of the UN Charter — sometimes called the “Palestine clause” — preserves certain rights and obligations inherited from the League of Nations Mandate system, and it is cited by authors and advocates who argue Mandate-era Jewish settlement rights survived the transition to the UN [4] [5] [6]. Proponents of that view assert Article 80 “preserved the validity of Mandate-based rights” and therefore undercuts UN claims that Israeli settlement is per se illegal [7] [6]. Available sources show this reading is advanced by legal commentators and advocacy sites but does not reflect the reasoning in the ICJ advisory opinion or the majority of UN resolutions cited by the General Assembly [1] [2].

3. The UN’s evidentiary focus: Geneva Conventions, discrimination and annexation

UN texts and the ICJ opinion emphasize international humanitarian law (notably the Fourth Geneva Convention’s rules on an occupying power) and find that Israeli policies — settlements, annexatory acts, and separation mechanisms — undermine the protected population’s rights and in some instances amount to breaches of other instruments, including the Convention on the Elimination of All Forms of Racial Discrimination as observed by the Court [1]. The General Assembly’s draft resolutions recall the ICJ’s finding and demand compliance with those international obligations [1].

4. Counter-arguments invoking Article 80 and historic legal claims

A competing legal narrative argues the Mandate and Article 80 secure enduring Jewish rights in “western Palestine” and that no Palestinian sovereign ever held the territory in a way that makes Israel a classical occupier; advocates cite uti possidetis and Mandate provisions to deny the label “occupation” [6] [8] [7]. These sources present that position as the basis for rejecting UN and ICJ conclusions, and they stress that some Israeli authorities and supportive commentators maintain the UN’s frequent resolutions are politically motivated rather than determinative of legal title [8] [9].

5. Institutional limits: advisory opinions, General Assembly politics, and enforcement

The ICJ’s advisory opinions are not directly enforceable but carry significant legal and political weight; UN General Assembly resolutions are largely declaratory and reflect member-state majorities rather than binding force [2] [1]. The record shows broad General Assembly support for resolutions calling for withdrawal and for the invalidity of annexation acts, but those political texts coexist with a sustained counter-narrative that insists Article 80 and Mandate-era instruments preserve different legal conclusions [3] [7].

6. What reporting and sources do not settle: Article 80’s decisive effect on modern claims

Available sources do not settle whether Article 80 legally overrides the ICJ’s reasoning or modern interpretations of the Geneva Conventions; some commentators treat Article 80 as dispositive for Israeli claims of settlement rights, while UN bodies and the ICJ focus on contemporary obligations and findings of unlawfulness tied to occupation-era conduct [6] [1] [2]. That evidentiary and interpretive gap explains why the dispute remains politically and legally unresolved in practice.

7. Bottom line for readers navigating competing claims

The UN’s claim of illegality derives from the ICJ’s advisory opinion and repeated General Assembly actions that interpret occupation law and settlement activity as unlawful; a persistent counter-claim anchored in Article 80 and Mandate-era rights disputes that interpretation and argues for a different legal genealogy [2] [1] [6]. Readers should treat the UN/ICJ position as the authoritative international institutional judgment relied upon by most UN texts, while recognizing that influential legal and political actors explicitly contest that judgment on Mandate/Article 80 grounds [1] [7].
