Does Israel's Phased Withdrawal End Gaza's Occupation?

Record status, scope, and non-advice notice

This article is legal background analysis, not legal advice. It is written for issue-spotting and source-linked research discipline in a live compliance file; it does not assess any client’s facts, sanctions exposure, procurement decision, or humanitarian-operation authorization.

• Current record date: August 1, 2026, UTC.
• Legal-background review basis: ICJ advisory-opinion materials last checked for this record on August 1, 2026. The July 19, 2024 advisory opinion is non-binding and included an 11-4 vote on the unlawfulness and withdrawal conclusions; the October 22, 2025 advisory opinion is also non-binding and was adopted 10-1, with Judge Sebutinde dissenting. [1][2]
• Yellow Line factual baseline: last checked for this record on August 1, 2026. The operative range used here is roughly 53-58% of Gaza under IDF control behind the Yellow Line, with later plan stages described as reducing that area to roughly 40% and then 15%, followed by a security perimeter. [3][4][5]
• Scope: this is a Gaza occupation-law analysis under the effective-control test. It does not treat the ICJ’s broader 2024 unlawfulness findings for the West Bank and East Jerusalem as automatically dispositive for Gaza, and it separates occupation law from conduct-of-hostilities law even where both may apply at the same time. [1][2]

The live question is narrower than whether a withdrawal looks complete from a map or a broadcast feed. The legal question is whether Israel’s authority in Gaza can still be exercised, and, if it can, which duties follow from the particular powers retained. A phased withdrawal across a Yellow Line can reduce the area and intensity of control. It does not, by that fact alone, answer whether occupation-law obligations have ended.

The test is exercisable authority, not visible troop presence

Hague Regulations Article 42 frames occupation around authority that “has been established and can be exercised.” The ICJ used that formulation in its July 2024 advisory opinion and treated the inquiry as functional: the question is not only where forces are stationed, but whether the occupying power retains effective control over matters such as borders, movement, taxes, and buffer-zone arrangements. [1]

That point is what makes Gaza difficult after any withdrawal announcement. In 2024, the Court concluded that Israel’s 2005 withdrawal from Gaza did not “entirely release” it from obligations under the law of occupation. The obligations remained “commensurate with the degree” of Israel’s effective control, and the Court identified retained control over borders, movement arrangements, taxes, and the buffer zone as relevant to that assessment. [1]

The October 2025 advisory opinion did not relax that test. It stated that Israel’s effective control had “increased significantly” since October 7, 2023, that occupation-law obligations remain scaled to the degree of control, and that occupation law can apply alongside conduct-of-hostilities rules during active hostilities. That last point matters in compliance work: an active battlefield does not turn the occupation-law file into a null set. [2]

The non-binding character of the opinions should be recorded, but it should not be used as an excuse to ignore the test they articulate. Advisory opinions are not judgments between parties with binding operative orders. They are, however, primary ICJ statements of international law. For counsel, that makes them the starting point, not an optional commentary layer.

The Yellow Line changes the control map; it does not answer the legal question by itself

The October 2025 ceasefire framework, as publicly reported, contemplated a phased Israeli withdrawal in Gaza rather than an immediate removal of all Israeli authority. The White House plan, as described by the Council on Foreign Relations and the UK Home Office bulletin, provided for later reductions to roughly 40% and 15% of Gaza, with a final security perimeter remaining until Gaza is considered secure from any resurgent terror threat. [3][4]

For the present record, the critical working fact is that roughly 53-58% of Gaza remained under IDF control behind the Yellow Line in the December 2025 Secretary-General reporting. That is not a minor cartographic footnote. If a state retains authority over more than half the territory, while further withdrawals are staged and conditional, the legal analysis has to ask what authority remains exercisable in that area and through the perimeter system. [5]

The reported movement of Yellow Line marker blocks is not used here to prove a battlefield fact beyond dispute. BBC Verify’s January 2026 satellite analysis reported that 16 marker blocks had moved deeper into Gaza by an average of about 295 meters; the IDF disputed the finding. The responsible legal treatment is to keep both entries in the file and to treat the Yellow Line as a factual condition requiring update discipline. [6]

OHCHR’s April 2026 warning points in the same operational direction without resolving the occupation question. It described the line as a “shifting and poorly marked deployment line” and stated that targeting civilians who are not directly participating in hostilities is a war crime regardless of their proximity to deployment lines. That statement belongs primarily in the conduct-of-hostilities file, but it also reinforces why a changing line cannot be treated as a stable legal endpoint. [7]

Why the 2005 disengagement is the wrong shortcut and the right precedent

The 2005 disengagement materials asserted that, after completion of the plan, there would be “no basis to the claim that the Strip is occupied land.” That is the clean proposition often attractive in a withdrawal memo: troops out, occupation over. [8]

The ICJ did not accept that proposition as a complete answer. Its 2024 analysis treated 2005 as a shift in the degree and form of Israeli control, not as a legal switch that necessarily turned all occupation obligations off. The Court’s language is careful: Israel was not “entirely released” from its obligations under the law of occupation, and those obligations remained “commensurate with the degree” of effective control retained. [1]

That makes 2005 important, but not for the reason sometimes assigned to it. It is not a clean precedent for ending occupation whenever forces withdraw from populated areas. It is the controlling precedent for scaled obligations where effective control remains through borders, movement restrictions, taxation mechanisms, buffer zones, or other retained powers. [1]

The same reasoning applies to the Yellow Line regime. If later phases reduce the area of IDF control, the legal consequence may be a reduced set of occupation-law obligations in some places and a more concentrated set in others. The consequence is not automatic termination unless authority can no longer be exercised. A partial withdrawal is therefore evidence in the analysis, not the conclusion.

The Gaza analysis must be kept separate from the West Bank unlawfulness holding

There is a second discipline point. The 2024 advisory opinion’s unlawfulness analysis rested heavily on settlement, annexation, and related facts in the West Bank and East Jerusalem. Judge Cleveland, while joining important parts of the opinion, cautioned that the jus ad bellum unlawfulness findings did not reach Gaza. Judges Iwasawa and the joint declaration of Judges Nolte and Cleveland also recorded caveats about how withdrawal duties may be implemented, including that implementation may differ territory by territory. [9][10]

That caveat does not weaken the Gaza effective-control inquiry. It prevents a different error: using the West Bank and East Jerusalem unlawfulness holding as a shortcut for Gaza. For Gaza, the core question remains the Article 42 question as applied by the ICJ in 2024 and reaffirmed in 2025: what authority is established, and can it be exercised? [1][2]

Retained powers to monitor after a phased withdrawal

A useful file should not stop at “occupation continues” or “occupation ended.” Those labels are too blunt for the decisions counsel actually has to support. The more durable analysis identifies each retained power, ties it to a duty, and records what evidence would show that the power has expanded, contracted, or ended.

The list is not a substitute for field verification. It is a way to prevent the legal conclusion from floating above the facts. If a crossing changes hands, the file changes. If a security perimeter becomes smaller but more restrictive, the file changes. If a nominal withdrawal leaves approval authority over aid, movement, or tax mechanisms in the same place, the legal file should not treat the word “withdrawal” as dispositive.

Aid access is not a side issue

Aid access deserves a separate note because it is often described as logistics rather than authority. In occupation-law analysis, that framing is too narrow. If a state can decide whether relief reaches civilians, which agencies may operate, which routes may be used, or whether essential supplies are delayed or denied, those facts may indicate exercisable authority. The 2025 ICJ opinion’s coexistence point matters here: rules governing hostilities do not displace occupation-law duties merely because fighting continues. [2]

For humanitarian-law counsel, the practical record should therefore capture decisions, not only outcomes. The file should show who requested access, who approved it, who denied it, who imposed conditions, who controlled the route, and whether the denial was tied to security, capacity, political conditions, or no stated reason. Those are the facts that can be mapped to retained authority.

Crossings and movement are usually where the binary theory fails first

A state can remove forces from some populated areas and still control whether people and goods move. The ICJ’s 2024 opinion put borders and movement in the center of its Gaza analysis for that reason. If the Yellow Line regime leaves Israel able to approve or prevent movement across crossings, direct convoys away from certain routes, restrict return to areas, or maintain exclusion zones, the occupation-law inquiry remains live for those functions. [1]

Taxation and fiscal controls can be quieter than checkpoints

Taxation appeared in the ICJ’s list of retained-control factors after the 2005 disengagement. That is a useful warning against over-weighting visible military facts. Control over customs, revenues, import classifications, or fiscal transfers can shape civilian administration even when it is exercised from outside the territory. Where those controls continue, the obligation analysis should not be closed merely because a ground unit has moved behind a line. [1]

Third-state duties should track the same retained powers

Third-state analysis has to be handled with the same separation. The 2024 advisory opinion addressed obligations of all states, including non-recognition, non-assistance, and duties connected to ensuring respect for the Geneva Conventions. But counsel should not lift those conclusions into Gaza without preserving the basis for each duty and the caveats around the opinion’s territorial reasoning. [1][9][10]

For Gaza, the cleaner compliance path is to tie third-state review to the continuing application of occupation law and international humanitarian law where effective control remains. That means the same retained powers that keep the occupation-law file open—crossings, aid access, airspace, security zones, movement controls, taxation, and perimeter authority—also identify the places where procurement, financing, export, assistance, and recognition questions may require review.

• For sanctions and export counsel: identify whether the transaction supports a retained-control function, a security perimeter, a crossing, surveillance, movement control, or denial-and-approval architecture.
• For humanitarian organizations and donors: record who controls access, what conditions are imposed, and whether denial of access is tied to a party with exercisable authority over the route or crossing.
• For in-house reviewers: separate support for civilian relief from support that may help administer, entrench, or operationalize a retained-control system.
• For knowledge-management staff: keep the 2024 West Bank and East Jerusalem unlawfulness holdings in a separate section from the Gaza effective-control file, with cross-references only where the opinion itself makes the link.

The point is not that every third-state duty has the same threshold or the same consequence. It is that a declaration of phased withdrawal is not enough to close the review. If authority remains exercisable through the Yellow Line system or through functional controls outside it, third-state compliance questions remain live.

What should not be made load-bearing

Casualty figures and alleged ceasefire-violation counts may be relevant to other legal and factual assessments, but they are not necessary to the occupation-law conclusion reached here. Where such numbers are party-reported or media-compiled, they should be attributed as such and should not substitute for the effective-control analysis.

The same caution applies to Phase 2 developments, the Board of Peace, and any international stabilization force arrangements as of Q3 2026. Those arrangements may change who exercises authority and where. Until the facts show that Israel can no longer exercise authority over the relevant functions, they change the monitoring file rather than closing it.

Usable legal conclusion as of August 1, 2026

A partial withdrawal can end occupation only when the former occupying power’s authority is no longer established and can no longer be exercised. Under the ICJ’s 2024 and 2025 effective-control analysis, Israel’s obligations in Gaza do not turn on troop visibility alone; they remain commensurate with retained control. [1][2]

On the currently verified record, the Yellow Line regime changes the degree and geography of Israeli control rather than ending it. Roughly 53-58% of Gaza remained under IDF control behind the line in the December 2025 reporting, later withdrawal phases were conditional and staged, and a security perimeter was contemplated. Those facts keep the occupation-law file open for the powers retained: airspace, security zones, aid access, crossings, movement controls, taxation, and any other authority that remains exercisable. [3][4][5]

The operational answer is therefore not “occupation yes” in the abstract or “occupation no” because a withdrawal phase occurred. It is that occupation-law obligations and related third-state review duties remain live to the extent of Israel’s retained effective control, and the Yellow Line must be monitored as a changing fact rather than treated as a legal endpoint.
