“Nulla poena lege” is a Latin legal principle that emphasizes on “no punishment without law”. This principle highlights that no individual can be punished for their actions unless there is a particular law that prohibits that action and prescribes a punishment for it. It means that people should be aware of the laws that govern their behavior, and punishments should only be applied when those laws are violated. This principle is crucial to ensure a fair and just legal system that respects the rule of law and safeguards individuals’ rights.
