Evidence is not evaluated by volume alone. Its value depends on where it came from, what it actually proves, how reliably it can be verified, and how it fits within the wider record.
These Evidence Standards explain how the International Sanctions Delisting Commission (“ISDC”) approaches documentary material, official records, testimony, public information, confidential material and other evidence used in sanctions review.
Purpose of the Evidence Standards
Sanctions review may involve large quantities of information from different jurisdictions, institutions, time periods and interested parties.
Some material may be authoritative but limited in what it proves. Other material may be highly relevant but difficult to authenticate. Multiple sources may also repeat the same original allegation without providing independent corroboration.
ISDC therefore evaluates evidence according to substance rather than appearance.
Where did the material originate?
Is the material what it claims to be?
What issue does it actually address?
How dependable is the source or record?
Is it supported independently?
No Single Factor Determines Evidentiary Weight
The evidentiary value of material depends on the combination of factors relevant to that material.
An official document may be authentic and authoritative as evidence of what an authority stated, while still requiring separate examination of the factual allegations contained within it.
Similarly, a document originating from an interested party may contain directly verifiable primary evidence even though the submitting party has an obvious interest in the outcome.
What proposition does this material actually establish — and how confidently can that proposition be relied upon?
Categories of Evidence
ISDC may consider a wide range of material. Categories assist analysis but do not operate as automatic rules of acceptance or rejection.
Sanctions listings, government notices, regulatory records, legislation, official statements and other material issued by competent public bodies.
Such material may carry substantial authority concerning the official position, procedural history or legal status.
Judgments, orders, pleadings, procedural records and other court material relevant to the facts or legal history of a case.
Contracts, filings, correspondence, corporate records, transactional records, contemporaneous documents and other original materials.
Academic, institutional, investigative or specialist research produced independently of the immediate parties to the review.
Reporting from journalistic sources may provide relevant factual leads, contemporaneous accounts or references to additional primary material.
Documents, explanations, legal arguments and evidence supplied by applicants, representatives or other interested parties.
Statements, expert opinions, declarations and other evidence based on personal knowledge or specialist expertise.
Websites, archived pages, digital communications, images, screenshots, databases, metadata or other electronically generated material.
Non-public information received subject to legitimate legal, security, privacy or source-protection concerns.
Evidentiary Weight
ISDC may describe the weight of evidence in qualitative terms rather than treating all accepted material as equally persuasive.
These categories are analytical descriptions, not mechanical scoring rules. Evidentiary significance depends on the question being examined.
Verification Gates
Before material is relied upon for a significant factual proposition, ISDC may consider the following verification questions.
Can the source, author, issuing body or chain of transmission be reasonably identified?
Is there reason to believe the document, image, communication or record has been altered, selectively presented or detached from material context?
Was the source in a position to know the information asserted, or is the statement based on hearsay, repetition or inference?
Does the source have a material interest in the outcome and, if so, how should that interest affect evidentiary weight?
Is the proposition supported by materially independent evidence, or do multiple sources ultimately trace back to the same original claim?
Was the material created contemporaneously with the relevant events, or substantially later with the benefit of hindsight?
Does credible evidence point in the opposite direction, and has that contradiction been adequately considered?
Existence Is Not Proof
A document can be genuine without proving the proposition for which someone relies upon it.
A sanctions notice may establish that an authority made a designation and stated particular reasons.
Whether every factual allegation underlying that designation remains accurate, complete or applicable may require separate evidentiary examination.
Source Independence
Multiple publications do not necessarily constitute multiple independent sources.
Ten articles repeating one original allegation may still amount to a single evidentiary origin.
ISDC therefore seeks, where practicable, to identify whether apparently separate sources are genuinely independent or merely derivative.
Are several sources independently confirming the proposition, or are several sources simply repeating one another?
Contemporaneous Evidence
Material created at or near the time of the relevant events may carry particular evidentiary value because it may be less affected by later reconstruction, litigation strategy or changes in interest.
Contemporaneity is not conclusive. A contemporaneous record may still be incomplete, inaccurate or self-serving.
Official Sources
Official records are often central to sanctions review and may carry significant authority.
ISDC nevertheless distinguishes between:
- evidence that an official decision was made;
- the reasons formally stated for that decision;
- the evidence underlying those reasons;
- ISDC’s independent assessment of whether those grounds remain applicable.
Court Decisions
Judicial decisions may be highly relevant, particularly where a court has examined the same events, evidence, ownership structure, conduct or legal issues relevant to a sanctions review.
Their evidentiary significance depends on matters including jurisdiction, procedural posture, applicable legal standard, issues actually decided and whether the decision remains in force.
Corporate and Commercial Records
Corporate registries, shareholder records, directorship records, regulatory filings, audited accounts and other business documentation may assist in assessing ownership, control and commercial relationships.
Formal ownership records should not automatically be treated as complete evidence of practical control where credible contrary material exists.
Media Evidence
Media reporting may assist in identifying relevant events, allegations, witnesses or underlying documents.
Greater weight may be given where reporting:
- identifies primary sources;
- is based on direct reporting rather than repetition;
- provides documentary support;
- has been independently corroborated;
- clearly distinguishes fact from allegation or commentary.
Digital Evidence
Digital material should be assessed with attention to its origin, date, context and susceptibility to alteration.
A screenshot may accurately capture what appeared on a screen without necessarily establishing who created the underlying content, when it was created, or whether context has been omitted.
Archived versions may assist in establishing historical website content, subject to consideration of archive date, completeness and technical reliability.
Relevant considerations may include sender and recipient identity, metadata, surrounding correspondence, completeness and whether the communication has been independently authenticated.
Database information should be evaluated with attention to who maintains the database, source methodology, update frequency and whether the record is primary or derivative.
Documents Provided by Interested Parties
Interested parties are often in possession of the most directly relevant evidence concerning their own corporate affairs, relationships, legal proceedings or changed circumstances.
Such material should not be rejected merely because the submitting party has an interest in the result.
At the same time, self-interest may affect evidentiary weight and may make independent verification particularly important.
Expert Evidence
Expert material should be assessed according to the relevance of the expertise, the factual basis of the opinion, methodology used, assumptions adopted and any material relationship between the expert and an interested party.
Expert status does not convert unsupported assumptions into established facts.
Witness Statements
Statements based on direct personal knowledge may carry evidentiary significance, particularly where they are detailed, internally coherent and independently supported.
Relevant considerations may include opportunity to observe, memory, consistency, interest in the outcome and corroborating evidence.
Anonymous Sources
ISDC generally favors sources whose identity and basis of knowledge can be assessed.
Anonymous information may nevertheless be relevant where there is a legitimate reason for protecting the source.
The inability to disclose identity may reduce the weight that can safely be placed on the material, particularly where independent corroboration is limited.
Confidential Evidence
Confidentiality may be necessary to protect legal privilege, personal information, security interests, commercially sensitive material or legitimate source concerns.
Confidential treatment does not exempt evidence from verification.
ISDC may distinguish between information that can be evaluated internally and information that can responsibly be published.
Redacted Documents
Redaction does not automatically make a document unreliable.
However, where removed material prevents meaningful understanding of the document’s source, meaning or context, the weight placed on the remaining content may be reduced.
Translations
Where evidence is translated from its original language, ISDC may consider the quality and source of the translation and may seek confirmation of material passages where linguistic precision could affect the analysis.
A translation should not silently alter the legal or factual meaning of the underlying text.
Document Integrity and Chain of Custody
Formal chain-of-custody procedures may be particularly relevant where the authenticity or integrity of material is disputed.
Depending on the significance of the evidence, ISDC may consider:
- who originally created or issued the material;
- how it was obtained;
- who possessed or transmitted it;
- whether the complete original is available;
- whether metadata or other technical information is available;
- whether there are signs of alteration or incompleteness.
Contradictory Evidence
Evidence inconsistent with a preferred conclusion should not be ignored.
Where credible sources conflict, ISDC may examine why they conflict and whether the difference can be explained by timing, perspective, methodology, incomplete information or competing interests.
An unresolved contradiction may justify a more cautious conclusion rather than artificial certainty.
Negative Evidence
The absence of a record may sometimes be relevant, but absence should be interpreted cautiously.
Failure to locate evidence of an event does not necessarily prove that the event did not occur.
Negative evidence may carry greater weight where a reliable record would ordinarily be expected to exist if the proposition were true.
Changed Circumstances
ISDC’s work may require comparison between the evidentiary position at the time of designation and the position at the time of review.
Evidence of changed circumstances may include:
- changes in ownership or control;
- termination of relevant commercial relationships;
- subsequent judicial findings;
- changes in official status;
- corporate restructuring;
- passage of time combined with verified factual developments;
- new information not available at the time of designation.
A change must be relevant to the grounds under review. Change alone does not necessarily justify a different sanctions outcome.
Evidence Submitted After Publication
New evidence may be assessed after an ISDC publication has been issued.
Depending on its significance, later evidence may justify an update, clarification, correction or substantive reconsideration of an earlier assessment.
Evidence That Cannot Be Verified
Information may still be recorded as part of the review where complete verification is not possible.
ISDC should nevertheless avoid presenting unverifiable material with a degree of certainty that the evidentiary record does not support.
When verification ends, certainty should end with it.
Volume Does Not Equal Strength
A large evidentiary record is not necessarily a strong evidentiary record.
Hundreds of derivative references may carry less analytical value than a small number of reliable primary documents.
ISDC therefore seeks to identify the evidentiary foundation of a claim rather than measuring support by the number of pages or references.
Standard of Evidentiary Expression
ISDC may use calibrated language to reflect the strength of the record. Depending on context, formulations may include:
- “the record establishes”;
- “the available evidence strongly indicates”;
- “the evidence supports”;
- “the available material suggests”;
- “the proposition remains disputed”;
- “the evidence is insufficient to establish”;
- “ISDC is unable to reach a reliable conclusion on the present record.”
The wording used should correspond to the actual evidentiary position.
Evidence and Legal Analysis
Evidence establishes or informs factual propositions. Legal analysis considers the significance of those facts under the relevant sanctions framework.
ISDC seeks to avoid treating a legal conclusion as though it were itself evidence of the facts required to support that conclusion.
Evidence and Recommendations
Evidence does not automatically dictate a recommendation without analysis.
The final assessment may require consideration of:
- the original grounds for designation;
- the present factual record;
- the reliability and weight of relevant evidence;
- material changed circumstances;
- the applicable legal or administrative framework;
- unresolved factual uncertainty.
Final Evidentiary Review
Before a material conclusion is published, ISDC should be able to identify the principal evidence supporting that conclusion and the principal evidence that materially challenges it.
Where a conclusion depends materially on a source with significant unresolved limitations, those limitations should be reflected in the analysis.
Evidence should be strong enough for the conclusion stated — not merely available enough to be cited.
ISDC therefore distinguishes between possession of information, verification of information and the evidentiary weight that information can responsibly bear.
