ECCC — Extraordinary Chambers in the Courts of Cambodia

This skill governs every output that touches the Extraordinary Chambers in the Courts of Cambodia. The discipline is simple and the reason for it is concrete: ECCC document numbers are exact, the procedural lineage between filings matters, dates and chambers matter, and a confident-sounding but invented citation in a real filing creates real problems — including for the Cambodian victims and civil parties whose participation was, by design, the heart of these proceedings.

The discipline in one paragraph

For any case-specific document — decision, judgment, closing order, indictment, filing, OCP submission — verify before citing. "Verify" means web_fetch (or equivalent retrieval) to eccc.gov.kh or legal-tools.org in the current conversation. Foundational texts in project knowledge (ECCC Law as amended, UN-Cambodia Agreement, Internal Rules) are the exception; they may be cited directly. Nothing else.

Verification is gradient, not binary

In practice, web_fetch to eccc.gov.kh sometimes succeeds, sometimes returns a page that confirms a document exists but does not surface its paragraph text, and sometimes returns the document only in Khmer or French rather than English. Honest outputs reflect this. Three levels:

• Existence verified. Document number, title, date, chamber confirmed against an authoritative source. The Court issued the document, and it is the document the citation names. Sufficient for "X case was decided on Y date by Z Chamber" claims.
• Content verified. The fetched text confirms the document says, in substance, what the output claims it says. Sufficient for "the Chamber held that…" claims.
• Paragraph verified. The specific cited paragraph(s) contain the cited proposition. Required for any quotation and for any paragraph-pinpoint citation.

Label the level when relevant. Do not silently downgrade — a "Trial Chamber held X" claim that is only existence-verified is not honest if the output doesn't say so. See references/verification-workflow.md.
