SINGLE CHAPTER-GENERAL PRINCIPLES

Article 1
Principle of legality

1- An act may only be criminally punished if it was determined punishable by law before the act was committed.

2- Security measures may only be applied to cases of perilousness, if its conditions are determined by law previous to its fulfilment.

3- An appeal to analogy is not permitted to qualify an act as criminal, to define a case of perilousness, or to determine a penalty or a corresponding security measure.
