Article: 20
Nobody shall be punished for acts or omissions that did not constitute an offence under national or international law at the time of commission or omission.

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.
