Provisions of this Code which attach a civil sanction or penalty or a deprivation of rights to acts or omissions which were not penalized by the former laws, are not applicable to those who, when said laws were in force, may have executed the act or incurred in the omission forbidden or condemned by this Code.
If the fault is also punished by the previous legislation, the less severe sanction shall be applied.
If a continuous or repeated act or omission was commenced before the beginning of the effectivity of this Code, and the same subsists or is maintained or repeated after this body of laws has become operative, the sanction or penalty prescribed in this Code shall be applied, even though the previous laws may not have provided any sanction or penalty therefor. (Rule 3a)
