Quizplus · Accepted Answer

The principle of legality, also known as the principle of legality and strict interpretation, holds that an individual cannot be punished for conduct that is not already specifically prohibited by law. This means that there must be a specific law defining a crime and setting out the punishment before a person can be punished for that crime. This principle is a fundamental protection of individual rights and ensures that the government cannot punish someone for conduct that was not known to be illegal at the time they engaged in it.
