Principles in Criminal Law
Principle of Legality
​
The principle of legality in criminal law, often summarized by the Latin phrase “nullum crimen sine lege” (no crime without law), is a fundamental concept that states that an act cannot be considered a crime unless it is clearly prohibited by law. This principle ensures that individuals are not subject to prosecution or punishment for conduct that was not defined as criminal at the time it was committed.
Key aspects of the principle of legality:
1. No Crime Without Law:
The principle of legality in criminal law ensures that an individual cannot be prosecuted or convicted for an act that was not explicitly defined as a crime by law. This principle protects individuals from arbitrary prosecution and ensures that only acts specifically prohibited by law can result in punishment.
For example, if an act was legal when committed, a person cannot later be charged with a crime if a law is passed making that act illegal, as retroactive laws are prohibited under this principle. This safeguards against unjust legal consequences for actions that were lawful at the time.
​
Rimando v. Commission on Elections (G.R. No. 176364, 2009): This case involved a security agency head who was held liable for failing to secure a permit for his guards to carry firearms during the election period. The Supreme Court ruled that there was no law punishing the mere failure to secure such authority, thus absolving Rimando of criminal liability. The Court reiterated that "nullum crimen, nulla poena sine lege" applies, meaning there can be no crime or punishment without a law explicitly defining the offense.
2. No Punishment Without Law:
Nullum poena sine lege can be paraphrased as “no punishment without law.” This legal principle asserts that an individual cannot be penalized for an act unless that act has been explicitly defined as a crime by law. Essentially, it protects individuals from arbitrary prosecution by ensuring that criminal responsibility is based on clearly written laws, and retroactive laws that impose punishment for actions previously lawful are prohibited. This principle is fundamental in ensuring fairness in criminal justice systems worldwide.
​
This principle is embodied in the 1987 Constitution, particularly under Article III, Section 21, which states:
“No person shall be deprived of liberty without due process of law, nor shall any person be subject for the same offense to be twice put in jeopardy of punishment.”
This provision indirectly supports the principle of legality by guaranteeing that no individual can be punished for an act unless it is defined by law and due process is followed.
Additionally, Article 22 of the Revised Penal Code (RPC) further reinforces this principle, stating that criminal laws shall not be retroactive, unless favorable to the accused. The principle also aligns with the rule against ex post facto laws, which are prohibited under Article 4 of the Constitution, ensuring that a law cannot punish acts that were legal when committed.
3. Strict Construction of Criminal Laws:
• Criminal statutes must be interpreted strictly and narrowly, meaning that ambiguous laws should be interpreted in favor of the accused. This ensures that laws are not applied beyond their clear meaning or intent.
• Example: If a law prohibits “driving under the influence of alcohol,” it cannot be extended to prohibit other substances not clearly listed in the law.
4. Protection Against Retroactive Legislation:
• The principle of legality ensures that laws are not applied retroactively. Criminal laws should not apply to acts that were committed before the law came into effect.
• Example: A person cannot be prosecuted for an action that was legal at the time it was performed but became illegal after the fact.
Importance of the Principle of Legality:
• Prevents arbitrary rule: The principle of legality prevents governments from imposing arbitrary punishments on individuals, ensuring fairness and stability in the legal system.
• Promotes transparency: Citizens are informed about what conduct is criminal and what penalties apply, which promotes public confidence in the legal system.
• Safeguards individual rights: It protects individuals from being subjected to penalties for acts that were not crimes at the time they were committed.
Exceptions and Variations:
Some legal systems, such as international criminal law, may allow exceptions to the principle of legality for crimes like genocide or war crimes, which can be prosecuted even if the law was not explicitly in place at the time of the offense (principle of jus cogens or peremptory norms of international law).
In the Philippines, the principle of legality is enshrined in Article 3 of the Revised Penal Code, which states that there shall be no crime without law, and that penal laws should not have retroactive effect unless they benefit the accused.
Case:
Peñalosa v. Ocampo, Jr. (G.R. No. 230299, 2023) - The Supreme Court ruled that an allegedly libelous Facebook post made before the enactment of the Cybercrime Prevention Act could not be punished under the Revised Penal Code, as there was no law defining and penalizing internet libel at the time of the alleged offense. This case clearly illustrates the application of "nullum crimen sine lege."

In summary, the principle of legality is a fundamental safeguard in criminal law that ensures people can only be charged with crimes and punished for acts that are clearly defined by law. It prevents retroactive prosecution and arbitrary punishment, ensuring fairness and predictability in the legal system.
