As there is a dispute between two different interpretations of international law regarding Israel, why is Jewish presence within their mandated lands called illegal rather than disputed?

Executive summary
Most international bodies and many governments characterise Israeli settlements in the West Bank, East Jerusalem and the Golan Heights as illegal under international law, citing the Fourth Geneva Convention and successive UN resolutions; the International Court of Justice issued an advisory opinion in July 2024 finding Israel’s presence in the Occupied Palestinian Territory unlawful and calling for evacuation and dismantling of settlements [1] [2] [3]. Israel and some of its domestic legal institutions treat settlements as lawful under Israeli law, and the government has legalized outposts and approved dozens of new settlements since 2022, creating a sharp legal and political divergence between domestic Israeli law and the international consensus [4] [5] [6].
1. Why most international actors call settlements “illegal” — the treaty and U.N. record
The dominant international legal argument rests on Article 49 of the Fourth Geneva Convention and repeated U.N. pronouncements that moving an occupier’s civilian population into occupied territory violates that provision; Security Council and General Assembly texts and U.N. expert reports have repeatedly declared the settlements to have “no legal validity” and to constitute violations of international law [1] [3]. The International Court of Justice’s 2024 advisory opinion amplified that position, concluding Israel’s continued presence in occupied Palestinian territory is unlawful and recommending dismantling settlements and remedial measures [2] [3].
2. Israel’s competing legal frame: domestic law and historical claims
Israeli authorities do not accept the international consensus. Israel administers the West Bank as “Judea and Samaria” and applies domestic administrative and planning mechanisms to recognize settlements, legalize outposts, and claim territory as State Land under Israeli law; the government asserts that settlements are lawful under Israel’s own legal system [4] [6]. Israeli courts and legal advisers have at times reached differing conclusions internally, and successive Israeli governments have advanced legalization and authorization measures for dozens of new settlements since 2022 [5] [7].
3. Facts on the ground that shape legal and political labels
Between cabinet decisions, defence ministry confirmations and activist tallies, the pace of approvals and retroactive legalization has accelerated: analysts and NGOs document the formal establishment or legalization of dozens of settlements and outposts in recent years, while Israeli ministries have allocated major budgets for expansion—moves which outside actors characterise as entrenching control and changing facts on the ground [7] [8] [6]. International critics say legalization after-the-fact does not negate obligations under international humanitarian law [1] [2].
4. Why “illegal” rather than “disputed” is the common international phrasing
“Illegal” is used because many international legal instruments, U.N. bodies and the ICJ interpret the occupation and Article 49 as creating a clear prohibition; those bodies therefore treat ongoing settlement policy as a straightforward legal breach rather than merely a political disagreement [1] [2]. By contrast, “disputed” is a political label that avoids adjudicating treaty obligations; states or commentators who prioritise political negotiation or who accept Israeli sovereignty claims sometimes use “disputed” instead — but that terminology departs from the dominant U.N./ICJ legal findings cited above [3] [1].
5. Competing viewpoints and their stakes
International institutions and many foreign governments frame the issue as legal and rights-based, calling for cessation, dismantling and sanctions in some cases; human-rights groups echo that stance and seek accountability [2] [1]. Israeli officials and supporters argue national security, historical entitlement, and domestic legal authority justify settlements and legalization; they stress that some outposts were unauthorized and later regularized under Israeli procedures [4] [5]. These are not merely academic disagreements: each framing carries different policy consequences — from sanctions and divestment to parliamentary recognition and infrastructure investment [8] [7].
6. What this means for ordinary descriptions and reporting
When major international bodies and courts have issued legal findings, journalists and diplomats commonly use “illegal” to reflect that authoritative international judgment [2] [1]. Reporting that instead calls settlements “disputed” typically signals either deference to Israeli domestic claims or an editorial decision to foreground political negotiation rather than legal adjudication; readers should note which legal frame an outlet is adopting and why [4] [6].
7. Limitations and open questions in available reporting
Available sources document the international legal consensus and Israel’s countervailing domestic legal actions, but they do not resolve every fine-grained legal question — for example, they do not provide a universally binding adjudication by a court of final jurisdiction over every settlement instance, and domestic Israeli legal reasoning varies by case and time [1] [4]. Where sources disagree, the clearest divide is between international judicial/bodies’ interpretations and Israel’s domestic law and policy choices [2] [4].
Bottom line: “illegal” is the internationally dominant legal judgment because U.N. organs and the ICJ read treaty obligations to proscribe settler transfer into occupied territory; Israel rejects that reading and applies its own domestic law to legalize settlements, producing the persistent—and politically explosive—gap between legality under international law and legality under Israeli law [1] [2] [4].
