General Provisions
Article 24: No legislative provision shall have retroactive effect, except where it imposes a lesser penalty. Procedural laws shall apply from the moment they go into effect, even to proceedings already in progress; however, in criminal proceedings, evidence already admit¬ted shall be weighed in accordance with the laws that were in effect when the evidence was admitted, insofar as this benefits the defendant.
When there are doubts as to the rule of law that is to be applied, the most beneficial to the defendant will prevail .
