CHAPTER II
OF THE OPERATIVE PERIOD OF A CRIMINAL LAW

ARTICLE 112-1

Conduct is punishable only where it constituted a criminal offence at the time when it took place.

Only those penalties legally applicable at the same date may be imposed.

However, new provisions are applicable to offences committed before their coming into force and which have not led to a res judicata conviction, when they are less severe than the previous provisions.

Article 22
Nullum crimen sine lege
1. A person shall not be criminally responsible under this Statute unless the conduct in question constitutes, at the time it takes place, a crime within the jurisdiction of the Court.
2. The definition of a crime shall be strictly construed and shall not be extended by analogy. In case of ambiguity, the definition shall be interpreted in favour of the person being investigated, prosecuted or convicted.
3. This article shall not affect the characterization of any conduct as criminal under international law independently of this Statute.
