Evidentiary Standards | Trump's War Crimes

ICC Evidentiary Thresholds

The International Criminal Court uses a graduated system of evidentiary standards. Each stage of proceedings requires a higher burden of proof than the last. These are the four levels, from lowest to highest:

1. Reasonable Basis to Believe — Article 53(1)

The lowest threshold in ICC proceedings. Used by the Prosecutor to decide whether to open a preliminary examination. The standard is "a sensible or reasonable justification for a belief" that crimes within the Court's jurisdiction have been committed. This does not require proof — it requires a rational basis for inquiry.

2. Reasonable Grounds to Believe — Article 58

The arrest warrant standard. A Pre-Trial Chamber must find reasonable grounds to believe a person has committed a crime before issuing a warrant. Higher than "reasonable basis" but still well below proof. Think of it as: the evidence, taken at face value, points toward guilt strongly enough to justify arrest.

3. Substantial Grounds to Believe — Article 61(7)

The confirmation of charges standard. Before a case goes to trial, the Pre-Trial Chamber must find "sufficient evidence to establish substantial grounds to believe" the person committed the charged crimes. The ICC has described this as requiring "concrete and tangible proof demonstrating a clear line of reasoning." This is where the prosecution must show its hand — the evidence has to hold together as a coherent case.

4. Beyond Reasonable Doubt — Article 66(3)

The trial conviction standard. The only standard that results in a guilty verdict. The accused is presumed innocent. The burden rests entirely on the Prosecutor. If reasonable doubt remains after full presentation of evidence, the verdict is not guilty.

How Our Classifications Map

Confirmed

ICC equivalent: Beyond reasonable doubt / Substantial grounds to believe

A formal legal finding exists — a tribunal ruling, court judgment, or equivalent authoritative determination. This is the highest classification in the archive and requires an actual adjudication by a competent court or tribunal, not merely strong evidence. The evidentiary standard depends on what stage that finding reached.

Currently, no incidents in this archive carry the "confirmed" classification. No international tribunal has yet adjudicated the conduct documented here.

Probable

ICC equivalent: Reasonable grounds to believe (Article 58 — arrest warrant threshold)

Multiple independent credible sources corroborate factual elements that map directly to specific articles of the Rome Statute, Geneva Conventions, or other binding instruments. Recognized legal authorities have published analyses reaching the same conclusion. This is enough evidence to justify an arrest warrant and charges — not enough to convict.

Every incident classified as "probable" has specific international law citations and published legal analyses from recognized authorities (Human Rights Watch, Amnesty International, Lawfare, Just Security, or equivalent) linking the documented conduct to Rome Statute articles.

Potential

ICC equivalent: Reasonable basis to believe (Article 53(1) — preliminary examination threshold)

Credible reporting indicates conduct that could constitute a violation of international law if the reported facts are accurate. The legal theory is recognized, but the factual record may be incomplete, contested, or based on fewer independent sources. This classification signals that the conduct warrants serious scrutiny — not that a violation has been established.

Enabling

ICC equivalent: Same evidentiary thresholds, applied to complicity

The documented conduct materially facilitates violations committed by others, within the meaning of Rome Statute Article 25(3)(c) — aiding, abetting, or otherwise assisting in the commission of a crime. This includes providing weapons, removing legal safeguards, or creating the conditions that make violations possible.

The "enabling" label indicates the actor's role — facilitating rather than directly committing — not a different evidentiary bar. The underlying conduct still has to meet one of the thresholds above.

Verification Status vs. Classification

These are two independent axes. They answer different questions.

Verification status answers: How well corroborated are the factual claims?

Classification answers: If the facts are as reported, what legal category does this conduct fall into?

These can diverge. An incident can be independently verified on the facts but only potential legally — strong evidence that specific events occurred, but the legal elements of a Rome Statute violation are unclear or contested. The facts are solid; the law is ambiguous.

The reverse is also possible. An incident can have a clear legal classification — the described conduct would unambiguously constitute a war crime — but weak verification. The law is straightforward; the facts are disputed.

Both axes matter. Neither substitutes for the other.

What This Archive Is Not

Not a court. We do not adjudicate guilt or innocence.
Not a prosecution brief. We do not advocate for specific charges against specific individuals.
Not a substitute for a formal investigation. The ICC, ICJ, or a competent domestic court conducts investigations. We organize public information.

Classifications on this site are editorial assessments informed by legal analysis. They reflect our reading of the publicly available evidence against the Rome Statute and customary international law. They are not legal determinations, and they carry no legal weight.

If any incident on this archive proceeds to a formal legal process, the classification here is irrelevant to that process. The court applies its own standards to its own evidence.

Rome Statute Articles Referenced

These are the articles most frequently cited across the archive.

Article 6 — Genocide. Acts committed with intent to destroy, in whole or in part, a national, ethnical, racial, or religious group. Includes killing, causing serious harm, inflicting destructive conditions of life, preventing births, and forcibly transferring children.

Article 7 — Crimes against humanity. Widespread or systematic attacks directed against a civilian population. Includes murder, extermination, enslavement, deportation, imprisonment, torture, sexual violence, persecution, enforced disappearance, apartheid, and other inhumane acts.

Article 8 — War crimes. Grave breaches of the Geneva Conventions and other serious violations of the laws of armed conflict. Covers both international and non-international armed conflicts.

Article 25(3)(c) — Aiding, abetting, or otherwise assisting. Individual criminal responsibility for facilitating the commission of a crime, including providing the means for its commission.

Article 25(3)(d) — Contributing to a group crime. Individual criminal responsibility for contributing to a crime committed by a group acting with a common purpose. The contribution must be intentional and made with knowledge of the group's criminal intent.

Article 28 — Command responsibility. Superior responsibility for crimes committed by subordinates. Applies when a commander knew or should have known about the crimes and failed to prevent or punish them. Covers both military commanders and civilian superiors, with a slightly different knowledge standard for each.
