Article 124
The provisions of the laws apply only to what occurs from the date the laws came into force, and have no retroactive effect. The law may state, in articles other than those pertaining to the penal code, that its provisions have a retroactive effect, with the agreement of the majority of the members of both the Consultative Council and the Chamber of Deputies, or if circumstances require it, the National Assembly.
2. If a State becomes a Party to this Statute after its entry into force, the Court may exercise its jurisdiction only with respect to crimes committed after the entry into force of this Statute for that State, unless that State has made a declaration under article 12, paragraph 3.
1. No person shall be criminally responsible under this Statute for conduct prior to the entry into force of the Statute.
2. In the event of a change in the law applicable to a given case prior to a final judgement, the law more favourable to the person being investigated, prosecuted or convicted shall apply.
