Doctrine Of Legality In Indian Criminal Law
I. Introduction
The Doctrine of Legality is a fundamental principle of criminal law that means “no crime and no punishment without law” (Nullum crimen sine lege, nulla poena sine lege). This doctrine ensures that:
An individual can only be punished for an act or omission that was clearly defined as a crime by law at the time it was committed.
Laws must be clear, ascertainable, and non-retrospective.
It protects citizens from arbitrary prosecution and retroactive penal laws.
In India, the Doctrine of Legality is grounded in Article 20(1) of the Constitution, which prohibits ex post facto laws in criminal matters.
II. Key Aspects of Doctrine of Legality
| Aspect | Explanation |
|---|---|
| No retrospective criminal laws | Laws imposing punishment cannot be applied retroactively to acts committed before the law. |
| Clarity and certainty | Laws must clearly define what constitutes an offense so individuals can regulate their conduct accordingly. |
| Non-arbitrariness | Laws must not be vague or overbroad; ambiguity invites arbitrariness. |
| Legality in punishment | No penalty can be imposed unless prescribed by law. |
| Principle recognized by courts | Courts enforce the doctrine to protect fundamental rights and prevent misuse of power. |

The law must give clear guidance on what constitutes sedition to avoid vagueness.
Significance:
Affirms that criminal laws must be clear and precise to comply with the Doctrine of Legality.
2. R. v. Shivaji Saheb (1932) (Privy Council decision, cited in Indian cases)
Facts:
Concerned retroactive application of criminal law.
