Mitigating, Aggravating, and Ordinary Circumstances in Philippine Criminal Law

In the architecture of the Philippine Revised Penal Code (RPC), the determination of a penalty is not a mechanical exercise. It is a nuanced process that balances the gravity of the act with the specific conditions surrounding its commission. These conditions are categorized as Circumstances affecting criminal liability.

Understanding the interplay between Mitigating, Aggravating, and Ordinary circumstances is essential for any legal practitioner or student of law, as they dictate whether a defendant receives the minimum, medium, or maximum period of a prescribed penalty.


1. Mitigating Circumstances (Article 13)

Mitigating circumstances are those which, if present in the commission of the crime, do not entirely free the actor from criminal liability but serve to reduce the penalty. They are based on a diminution of either the freedom, intelligence, or intent of the offender.

Classes of Mitigating Circumstances

  • Ordinary Mitigating: These can be offset by aggravating circumstances. If not offset, they lower the penalty to its minimum period.
  • Privileged Mitigating: These cannot be offset by any aggravating circumstance. Their presence typically lowers the penalty by one or two degrees (e.g., minority or incomplete self-defense).

Key Examples under Article 13:

  1. Incomplete Justifying/Exempting Circumstances: When not all requirements to justify an act (like self-defense) are present.
  2. Under 18 or Over 70 Years Old: The "Age of Enlightenment" and "Senility" factors.
  3. Praeter Intentionem: When the offender had no intention to commit so grave a wrong as that committed.
  4. Sufficient Provocation or Threat: Originating from the offended party immediately preceding the act.
  5. Vindication of a Grave Offense: Done in the immediate vindication of a grave offense to the practitioner, spouse, ascendants, descendants, or siblings.
  6. Passion or Obfuscation: Arising from lawful sentiments.
  7. Voluntary Surrender and Confession of Guilt: Must be spontaneous and made before the prosecution presents evidence.

2. Aggravating Circumstances (Article 14)

Aggravating circumstances are those which, if attendant in the commission of the crime, serve to increase the penalty without, however, exceeding the maximum period allowed by law. They are based on the greater perversity of the offender or the greater injury caused.

Classes of Aggravating Circumstances

  • Generic: Apply to all crimes (e.g., dwelling, nighttime).
  • Specific: Apply only to particular crimes (e.g., cruelty in crimes against persons).
  • Qualifying: Change the nature of the crime and the designation of the offense (e.g., treachery turns homicide into murder). These cannot be offset.
  • Inherent: Naturally accompany the crime (e.g., evident premeditation in robbery).

Key Examples under Article 14:

  1. Treachery (Alevosia): Employing means to ensure the execution of the crime without risk to the offender arising from the defense the victim might make.
  2. Abuse of Superior Strength: Taking advantage of physical, numerical, or weapon superiority.
  3. Evident Premeditation: Requiring a cool meditation on the crime and a persistence in the execution.
  4. Craft, Fraud, or Disguise: Used to facilitate the crime.
  5. Dwelling (Morosa): If the crime is committed in the victim's sanctuary without provocation.
  6. Recidivism: When the offender, at the time of trial, has been previously convicted by final judgment of another crime embraced in the same title of the RPC.

3. Alternative Circumstances (Article 15)

These are conditions that may be considered as either mitigating or aggravating, depending on the nature and effects of the crime and the conditions of the offender.

  • Relationship: Mitigating in crimes against property (theft/robbery); Aggravating in crimes against persons (killing a parent or spouse).
  • Intoxication: Mitigating if it is not habitual or subsequent to the plan to commit the crime. Aggravating if it is habitual or intentional (to "fortify" one's resolve).
  • Degree of Instruction/Education: Generally mitigating if low, though not in crimes against property or crimes of extreme cruelty.

4. The Rules of Application (Article 63 & 64)

The Revised Penal Code provides a strict formula for how these circumstances affect the final "imposable penalty" when the law prescribes a penalty composed of three periods (Minimum, Medium, Maximum).

Circumstances Present Imposable Period
No circumstances Medium Period
1 Mitigating / No Aggravating Minimum Period
1 Aggravating / No Mitigating Maximum Period
Both present They offset each other (arithmetic balance)
Two or more Mitigating / No Aggravating Penalty lowered by one degree

Comparison Table: Mitigating vs. Aggravating

Feature Mitigating Circumstances Aggravating Circumstances
Effect on Penalty Decreases (period or degree) Increases (period)
Effect on Crime Does not change the crime name Qualifying ones change the crime name
Basis Diminished voluntariness Greater perversity
Offsetting Can be offset (except privileged) Can be offset (except qualifying)

5. Important Legal Distinctions

  • Qualifying vs. Generic Aggravating: If treachery (qualifying) is present in a killing, the crime is Murder. If nighttime (generic) is also present, it is used to increase the penalty within the range of Reclusion Perpetua, but it does not change the crime's name again.
  • The "Pro Reo" Principle: In cases of doubt in the application of these circumstances, the interpretation most favorable to the accused is generally adopted.
