## Key Findings

- **SC1 — PROVED:** The Oslo II Accord (1995) does designate Area C (~60% of the West Bank) under "full Israeli civil and security control" pending final-status negotiations. This is non-controversial and confirmed by the treaty text itself (B1, B2).
- **SC2a — PROVED:** Oslo explicitly places Areas A (18%) and B (22%) under Palestinian civil administration, undercutting any claim that Israel exercises civil control over the *entire* West Bank (B3, B4).
- **SC2b — FAILS:** The Oslo designation does not contradict the *illegality* of the occupation under international law. The ICJ's July 2024 Advisory Opinion found Israel's continued presence in the Occupied Palestinian Territory unlawful, and explicitly stated that the Oslo Accords "cannot be understood to detract from Israel's obligations under the pertinent rules of international law." Fourth Geneva Convention Article 47 bars bilateral agreements from derogating international humanitarian law (IHL) protections regardless of local consent.
- **Overall:** The factual basis of the claim (Oslo creates Area C under Israeli administration) is correct. The logical conclusion (this *contradicts* the illegal occupation characterization) only holds for the "entire" dimension, not the "illegal" dimension — yielding PARTIALLY VERIFIED.

## Claim Interpretation

**Natural language:** The claim that Israel maintains an illegal occupation of the entire West Bank is contradicted by the Oslo Accords designating Area C as remaining under full Israeli civil and security administration pending final-status negotiations.

**Formal structure:** This is a compound claim requiring three sub-claims to all hold:

| Sub-claim | Property | Result |
|-----------|----------|--------|
| SC1 | Oslo II designates Area C under full Israeli civil and security administration pending final-status negotiations | **HOLDS** (2/2 sources confirm) |
| SC2a | Oslo shows the West Bank is NOT entirely under Israeli civil control (Areas A, B have Palestinian civil administration) | **HOLDS** (2/2 sources confirm) |
| SC2b | The Oslo designation contradicts the "illegal" characterization under international law | **FAILS** (0/2 sources; contradicted by ICJ 2024) |

**Operator note:** "Contradicts" requires that Oslo's arrangements undermine *both* the "entire" and the "illegal" dimensions of the challenged claim. SC1 + SC2a address "entire"; SC2b addresses "illegal." SC2b fails because Oslo is a bilateral administrative arrangement — not an international law adjudication. The Fourth Geneva Convention (Art. 47) bars bilateral agreements from waiving IHL protections; the ICJ has applied this principle directly to Oslo.

## Proof Logic

### SC1: Area C Designation (HOLDS)

The Israeli-Palestinian Interim Agreement on the West Bank and the Gaza Strip (Oslo II, signed September 28, 1995) divided the West Bank into three administrative zones. Area C is described as "full Israeli civil and security control — initially, circa 72–74% (first phase, 1995)" (B1). The agreement's own text defines Area C as "areas of the West Bank outside Areas A and B, which, except for the issues that will be negotiated in the permanent status negotiations, will be gradually transferred to Palestinian jurisdiction in accordance with this Agreement" (B2).

This establishes SC1 cleanly: Area C was placed under full Israeli civil and security administration, explicitly described as a transitional arrangement pending final-status negotiations. Two independently verified sources confirm this (B1, B2).

### SC2a: Not the "Entire" West Bank (HOLDS)

Oslo II simultaneously established that large parts of the West Bank are *not* under Israeli civil control:

- **Area A** (~18%): "full civil and security control by the Palestinian Authority" (B3)
- **Area B** (~22%): "Palestinian civil control and joint Israeli-Palestinian security control" (B4)

Together, Areas A and B encompass ~40% of the West Bank under Palestinian civil administration. This does undercut claims that Israel exercises civil control over the *entire* West Bank. Critics of Israeli policy typically use "occupied West Bank" or "Occupied Palestinian Territory" (the ICJ's preferred phrasing) rather than claiming uniform Israeli civil administration over the whole territory.

### SC2b: The "Illegal" Dimension (FAILS)

The key logical step — that Oslo's administrative designations contradict the *illegality* of the occupation — does not hold. Oslo II is a bilateral agreement between Israel and the Palestine Liberation Organization (PLO). It governs who administers which zones; it does not adjudicate the legal status of Israel's presence under international humanitarian law (IHL).

The International Court of Justice (ICJ) addressed this directly in its July 19, 2024 Advisory Opinion (*Legal Consequences arising from the Policies and Practices of Israel in the Occupied Palestinian Territory, including East Jerusalem*):

> "The Oslo Accords do not permit Israel to annex parts of the Occupied Palestinian Territory in order to meet its security needs. Nor do they authorize Israel to maintain a permanent presence."

> "[Such agreements] cannot be understood to detract from Israel's obligations under the pertinent rules of international law applicable in the Occupied Palestinian Territory."

The Court found by 11 votes to 4 that "Israel's continued presence in the Occupied Palestinian Territory is unlawful." The governing principle is Fourth Geneva Convention Article 47, which bars bilateral agreements between an occupying power and local populations from derogating IHL protections — regardless of consent.

Israel has argued (a minority legal position) that Palestinian consent via Oslo removes the occupation characterization. International tribunals — including the ICJ in both 2004 (the Wall Advisory Opinion) and 2024 — have consistently rejected this argument.

## Counter-Evidence Search

**Does Oslo contradict the illegality finding?**
The ICJ 2024 Advisory Opinion (fetched from icj-cij.org) addressed the Oslo Accords directly and found they neither authorize Israel's continued presence nor detract from its international law obligations. Legal scholarship reviewed (Opinio Juris, Indiana University Law Review, Max Planck Institute) uniformly holds that Oslo is not *lex specialis* overriding the Fourth Geneva Convention.

**Is Israel's consent argument legally viable?**
Israel argues that Palestinian consent via Oslo forecloses the "occupation" characterization (estoppel argument). This position is rejected by the ICJ and mainstream international law scholarship. Article 47 of the Fourth Geneva Convention was drafted precisely to prevent occupying powers from using bilateral arrangements to sidestep IHL. The ICJ 2004 Wall Advisory Opinion reached the same conclusion before the 2024 opinion.

**Does "entire West Bank" accurately describe the occupation claim?**
International bodies including the ICJ use "Occupied Palestinian Territory" (OPT) rather than "entire West Bank under Israeli civil control." Critics acknowledge Oslo's zone distinctions but argue Israel retains effective control over all areas via border control, movement restrictions, and the right to enter Areas A and B for security operations. SC2a holds on the face of the text but critics' actual claims are subtler than the straw-man of "Israel controls the entire West Bank civilly."

**Can Area C's designation legitimize Israeli control?**
No. The treaty establishes Area C as a transitional arrangement "gradually transferred to Palestinian jurisdiction" — the transfer never fully occurred, but the designation does not establish permanence or legality under international law.

## Conclusion

**Verdict: PARTIALLY VERIFIED**

The claim contains a true factual premise (SC1: Oslo does designate Area C under Israeli civil and security control, pending final-status negotiations) and a valid inference about the "entire West Bank" dimension (SC2a: Oslo's zone system shows Areas A and B are not under Israeli civil control). These two sub-claims hold.

However, the meta-claim — that this *contradicts* the assertion of an *illegal* occupation — fails on the critical "illegal" dimension (SC2b). Oslo II is a bilateral administrative agreement; it does not and cannot adjudicate the legality of the occupation under international law. The ICJ has ruled the occupation unlawful and has explicitly stated Oslo cannot diminish Israel's international law obligations. Fourth Geneva Convention Article 47 bars this kind of legal sidestep by design.

The claim as stated is a valid rebuttal to an oversimplified "entire West Bank" formulation, but it does not constitute a contradiction of the core illegality finding under international humanitarian law.
