## Claim Specification

*Source: proof.py JSON summary*

| Field | Value |
|-------|-------|
| Subject | Oslo Accords / Area C designation |
| Compound operator | AND (all sub-claims must hold) |
| SC1 property | Oslo II (1995) designates Area C under full Israeli civil and security administration pending final-status negotiations |
| SC1 operator | >= 2 sources confirming |
| SC1 operator note | Factual claim about treaty content; non-controversial |
| SC2a property | Oslo shows the West Bank is NOT entirely under Israeli civil control (Areas A and B have Palestinian civil administration) |
| SC2a operator | >= 2 sources confirming |
| SC2a operator note | Non-controversial; established by the treaty text |
| SC2b property | The Oslo designation contradicts the "illegal" characterization under international law |
| SC2b operator | >= 2 sources confirming |
| SC2b operator note | FAILS: ICJ 2024 Advisory Opinion explicitly found occupation unlawful and stated Oslo cannot detract from Israel's international law obligations. Fourth Geneva Convention Art. 47 bars bilateral agreements from derogating IHL protections. |
| Overall operator note | SC1 and SC2a hold; SC2b fails → PARTIALLY VERIFIED |

## Independent Source Agreement (Rule 6)

*Source: proof.py JSON summary*

| Cross-check | Sources | Confirming | Agreement |
|-------------|---------|------------|-----------|
| SC1: Area C under Israeli control | 2 | 2 | Yes |
| SC2a: Areas A, B under Palestinian civil control | 2 | 2 | Yes |
| SC2b: Oslo contradicts "illegal" characterization | 1 (adversarial) | 0 | No — ICJ 2024 directly contradicts |

**Independence note:** B1 and B3/B4 are drawn from the same Wikipedia article (two different sections confirming different sub-claims). B2 is from the Area C Wikipedia article (independent page). For a higher-assurance proof, primary treaty text (via UN UNISPAL) and the actual ICJ opinion PDF would be preferred. The Wikipedia sources are authoritative summaries of non-controversial, well-documented treaty content — the Oslo II zone designations are not disputed facts.

## Adversarial Checks (Rule 5)

*Source: proof.py JSON summary*

**Check 1:** Does the Oslo II Accord's designation of Area C contradict international legal characterizations of the occupation as illegal?
- Performed: Fetched ICJ Advisory Opinion summary (icj-cij.org/node/204176, July 19 2024). Searched for legal scholarship on Oslo Accords and occupation law. Reviewed Opinio Juris (2020), Indiana University Law Review, Max Planck Institute analysis.
- Finding: The ICJ 2024 Advisory Opinion found: (1) Israel's continued presence in the Occupied Palestinian Territory is unlawful; (2) the Oslo Accords do not permit Israel to annex OPT or maintain a permanent presence; (3) such agreements cannot detract from Israel's international law obligations. Fourth Geneva Convention Article 47 bars bilateral derogation of IHL. SC2b fails.
- Breaks proof: No (affects only SC2b, which was already categorized as failing)

**Check 2:** Does Israel's consent argument (Palestinians agreed via Oslo, so no occupation) have legal merit?
- Performed: Searched "Israel Oslo Accords estoppel no occupation argument international law." Reviewed JCFA article on Palestinian compliance with Oslo Accords. Reviewed Opinio Juris analysis.
- Finding: Israel's consent/estoppel argument is a minority legal position rejected by the ICJ (2004 and 2024) and mainstream IHL scholarship. Art. 47 GC IV was drafted to prevent exactly this kind of waiver-by-agreement.
- Breaks proof: No

**Check 3:** Does "entire West Bank" terminology accurately describe the occupation claim?
- Performed: Searched for UN, PA, and scholarly usage of "entire West Bank occupation." Reviewed Al Jazeera, Anera, UN sources on Areas A, B, C.
- Finding: Critics use "Occupied Palestinian Territory" (not "entire West Bank under Israeli civil control"). The "entire" qualifier is somewhat of a straw man — SC2a holds for the letter of the claim but critics' actual position is more nuanced (effective control via borders/movement even in Areas A/B).
- Breaks proof: No

**Check 4:** Can the Area C designation legitimize Israeli control, undermining the "illegal" label?
- Performed: Reviewed Oslo as lex specialis vs. lex generalis. Fetched Opinio Juris (2020). Searched for academic articles on Oslo II and Fourth Geneva Convention.
- Finding: Oslo is not lex specialis overriding GC IV. Bilateral consent cannot waive occupation law. PLO agreement to interim arrangements does not transform the legal character of the occupation. SC2b fails.
- Breaks proof: No

## Source Credibility Assessment

*Source: proof.py JSON summary*

| Fact ID | Domain | Type | Tier | Note |
|---------|--------|------|------|------|
| B1 | wikipedia.org | reference | 3 | Established reference source |
| B2 | wikipedia.org | reference | 3 | Established reference source |
| B3 | wikipedia.org | reference | 3 | Established reference source |
| B4 | wikipedia.org | reference | 3 | Established reference source |

**Note:** All four citations are Tier 3 (Wikipedia). For claims about non-controversial treaty content (the Oslo II zone designations are matters of public record), this is adequate. For the SC2b legal analysis, the ICJ Advisory Opinion (Tier 5 — intergovernmental) was consulted as an adversarial source but not cited as an empirical fact (per template: adversarial sources go in `adversarial_checks`, not `empirical_facts`). A production-grade proof should cite the ICJ opinion and the Oslo II treaty text directly from UN UNISPAL as Tier 5 sources.

| Fact ID | Extracted Value | Found in Quote | Quote Snippet |
|---------|----------------|----------------|---------------|
| B1 | "Israeli civil and security control" confirmed | Yes | "Area C (full Israeli civil and security control): initially, circa 72–74% (first phase" |
| B2 | "permanent status negotiations" confirmed | Yes | "areas of the West Bank outside Areas A and B, which, except for the issues that " |
| B3 | "Palestinian Authority" confirmed | Yes | "full civil and security control by the Palestinian Authority" |
| B4 | "Palestinian civil control" confirmed | Yes | "Palestinian civil control and joint Israeli-Palestinian security control" |

**Extraction method:** `verify_extraction()` from `scripts/smart_extract.py` — performs Unicode normalization and case-insensitive substring matching. All four keywords were found in their respective quotes on first pass.

**Normalization note (B1):** The initial quote used `~72–74%` (tilde + en-dash). The live page text uses `circa 72–74%`. Quote was corrected to match the live page text before verification. Unicode en-dash (U+2013) was preserved correctly.
