CHAPTER VI- DETERMINATION OF PUNISHMENT
Article 55- Defining sentence for several criminal acts
When actions or non-actions contain elements of more than one criminal act, and when the person has committed more than one criminal act for which no sentence has been given, the court first sentences every criminal act separately, giving a single sentence at the end, which consists of the heavier added sentence.
The heavier added sentence may exceed neither the total sum of the punishments determined separately, nor the maximum provided for the type of the sentence given.
When the court deems that committing more than one crime does not demonstrate the serious dangerousness of the defendant, it may give as a final sentence the heaviest punishment provided for one of the criminal acts.
In giving its final decision, the court sentences one or more than one of the supplementary punishments given separately for each particular crime
Multiplicity of criminal offences
