The Right to Equality
13. Equality before the law
(6) To ensure equality before the law, the state authority shall make procedures which are appropriate or which take into account the following principles, namely :
(c) no person shall be punished for any act which at the time of its commission was not an offence under the law, and also no penalty shall be imposed which is heavier than the penalty in force at the time the offence was committed ;
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.
