FUNDAMENTAL PRINCIPLES OF CRIMINAL LAW

Below is a comprehensive, structured outline and discussion of the Fundamental Principles of Criminal Law in the Philippines. The discussion draws primarily from the 1987 Philippine Constitution, the Revised Penal Code (Act No. 3815, as amended), and relevant jurisprudence. While criminal law is vast and continuously evolving, the key principles below serve as the bedrock of the Philippine penal system.

1. Definition and Sources of Criminal Law

1.1 Definition

  • Criminal Law is that branch of law which defines crimes, treats of their nature, and provides for their punishment.
  • In the Philippines, the core of criminal law is found in the Revised Penal Code (RPC) and in special penal laws (e.g., Dangerous Drugs Act, Anti-Graft and Corrupt Practices Act, Cybercrime Prevention Act).

1.2 Sources of Criminal Law in the Philippines

  1. Revised Penal Code (Act No. 3815)
    • This is the primary source of general criminal law. It took effect on January 1, 1932, and has since been amended by various laws (e.g., R.A. 7659, R.A. 8353, R.A. 9262).
  2. Special Penal Laws
    • Enacted by Congress to address specific crimes (e.g., illegal drugs, terrorism, money laundering, etc.).
    • Often contain their own specific definitions, penalties, and procedures.
  3. Philippine Constitution
    • Sets out fundamental rights and protections that affect criminal law and procedure (e.g., presumption of innocence, right to due process).
  4. Jurisprudence
    • Decisions of the Supreme Court interpreting statutes and constitutional provisions form part of the legal system.
  5. Rules of Court (particularly the Rules on Criminal Procedure)
    • Though primarily procedural, they interact with substantive criminal law in significant ways.

2. Overarching Constitutional Principles

2.1 Due Process of Law

  • Article III, Section 1 of the 1987 Constitution provides that no person shall be deprived of life, liberty, or property without due process of law.
  • In criminal proceedings, due process requires:
    1. An impartial court with jurisdiction.
    2. Accused is informed of the nature and cause of the accusation.
    3. Accused has the right to be heard and to present evidence.
    4. Judgment is rendered based on lawful evidence presented in a fair trial.

2.2 Presumption of Innocence

  • Article III, Section 14(2): “In all criminal prosecutions, the accused shall be presumed innocent until the contrary is proved.”
  • The prosecution bears the burden of proof beyond reasonable doubt.

2.3 Right Against Self-Incrimination

  • Article III, Section 17: No person shall be compelled to be a witness against himself/herself.
  • This principle is reflected in the Miranda doctrine (right to remain silent, right to counsel).

2.4 Right to Counsel

  • Article III, Section 14(2) also guarantees the right of the accused to be heard by counsel.
  • If the accused cannot afford counsel, the State must provide one (e.g., Public Attorney’s Office).

2.5 Prohibition Against Double Jeopardy

  • Article III, Section 21: No person shall be twice put in jeopardy of punishment for the same offense.
  • Double jeopardy attaches when:
    1. A valid complaint or information is filed.
    2. A competent court tries the case.
    3. The accused has been arraigned.
    4. The accused is acquitted, convicted, or the case is dismissed without the accused’s express consent.

2.6 Prohibition Against Ex Post Facto Laws and Bills of Attainder

  • Article III, Section 22: No ex post facto law or bill of attainder shall be enacted.
  • Ex Post Facto Law: A law which retroactively changes the legal consequences of actions.
  • Bill of Attainder: A legislative act that punishes an individual or group without judicial trial.

3. Fundamental Doctrines Underlying Criminal Law

3.1 Legality (Nullum Crimen, Nulla Poena Sine Lege)

  • “No crime when no law punishes it; no penalty when none is provided by law.”
  • Criminal liability cannot arise from an act or omission unless clearly prohibited and penalized by law.

3.2 Generality, Territoriality, and Prospectivity of Penal Laws

  1. Generality

    • Philippine criminal laws apply to all persons within Philippine territory, regardless of nationality, subject to certain exceptions (e.g., diplomatic immunities).
    • Example: A foreigner committing a crime in the Philippines can be prosecuted under Philippine criminal law.

  2. Territoriality

    • Philippine criminal laws generally govern all offenses committed within Philippine territory, including its atmosphere, waters, and maritime zone.
    • Exceptions:
      • Crimes committed in Philippine embassies/consulates abroad (subject to extraterritorial principles).
      • Crimes committed on Philippine ships or aircraft (under certain conditions).

  3. Prospectivity

    • Penal laws apply only to acts committed after their effectivity.
    • Exception: Penal laws may be applied retroactively when favorable to the accused (favor legis).

3.3 Strict Construction of Penal Laws in Favor of the Accused

  • Penal statutes are strictly construed against the State and liberally in favor of the accused.
  • Ambiguities in criminal provisions are interpreted to benefit the accused (rule of lenity).

3.4 Actus Non Facit Reum Nisi Mens Sit Rea (The Act Does Not Make One Guilty Unless the Mind Is Also Guilty)

  • Mens Rea (Criminal Intent) is generally required before criminal liability can attach, except in certain offenses classified as mala prohibita (prohibited acts, intention is immaterial).
  • Example:
    • Mala In Se: Crimes inherently wrong (e.g., murder, theft). Intent or criminal negligence is important.
    • Mala Prohibita: Acts made illegal by law/statute (e.g., illegal possession of firearms). Criminal intent is often irrelevant; the mere commission of the prohibited act suffices for liability.

3.5 Ignorantia Legis Non Excusat (Ignorance of the Law Excuses No One)

  • Every person is presumed to know the law; ignorance cannot be used as a defense.
  • Rationale: If ignorance were allowed, then laws would be easily circumvented.

3.6 Pro Reo Principle

  • When interpreting two or more possible interpretations of a penal provision, the interpretation lenient or favorable to the accused should prevail.

4. Classification of Crimes and Criminal Liabilities

4.1 Classification of Crimes Under the Revised Penal Code

  1. Felonies (RPC)

    • Classified by the manner or mode of commission:
      • Intentional Felonies: By dolo or deceit (with deliberate intent).
      • Culpable Felonies: By culpa or fault (with negligence, reckless imprudence).
    • Also classified by severity:
      • Grave Felonies: Punishable by capital punishment or afflictive penalties (reclusion perpetua, reclusion temporal, etc.).
      • Less Grave Felonies: Punishable by correctional penalties (prision correccional, arresto mayor, etc.).
      • Light Felonies: Punishable by arresto menor or fines not exceeding 40,000 pesos (subject to amendments).

  2. Offenses (Special Laws)

    • Violations of special penal laws, often referred to as “offenses.”
    • May require specific intent or not, depending on the statute.

  3. Misdemeanors

    • Minor offenses typically penalized by short-term imprisonment or small fines.

4.2 Degree of Participation

  • Principals: Those who directly commit, force or induce another to commit, or cooperate in the commission by another act without which it would not have been accomplished.
  • Accomplices: Those who cooperate in the execution by previous or simultaneous acts.
  • Accessories: Those who, after the commission of the crime, assist the offender to profit by the effects or evade justice.

4.3 Conspiracy and Proposal to Commit Felony

  • Conspiracy: When two or more persons agree to commit a felony and decide to commit it; the act of one is the act of all (for intentional felonies).
  • Proposal: If one person proposes to another the execution of a felony.
  • Not all conspiracies/proposals are punishable unless specifically penalized (e.g., treason, rebellion).

5. Circumstances Affecting Criminal Liability

Although these go deeper into “General Principles,” they remain fundamental because they affect the existence or degree of criminal liability:

  1. Justifying Circumstances (e.g., Self-defense, defense of relative, defense of stranger)
    • Act is lawful, thus no criminal liability.
  2. Exempting Circumstances (e.g., Insanity, minority, accident without fault)
    • No criminal liability, though the act is technically wrong, the law excuses the offender.
  3. Mitigating Circumstances (e.g., incomplete self-defense, voluntary surrender, passion or obfuscation)
    • Decrease the penalty.
  4. Aggravating Circumstances (e.g., nighttime, treachery, cruelty)
    • Increase the penalty.
  5. Alternative Circumstances (e.g., relationship, intoxication)
    • Can be mitigating or aggravating depending on the circumstances.

6. Penalties and Their Application

6.1 Types of Penalties Under the RPC

  1. Capital Punishment: Historically, the death penalty. Currently, the 1987 Constitution allows Congress to impose it for heinous crimes, but there is a de facto moratorium.
  2. Afflictive Penalties: Reclusion perpetua (20 years and 1 day up to 40 years), reclusion temporal, perpetual or temporary absolute disqualification, etc.
  3. Correctional Penalties: Prisión correccional, arresto mayor, suspension, destierro.
  4. Light Penalties: Arresto menor, public censure.

6.2 Imposition of Penalties

  • Courts generally impose penalties according to the penalty prescribed by law for the specific crime.
  • When mitigating or aggravating circumstances exist, courts adjust penalties according to the rules outlined in the RPC.

6.3 Subsidiary Penalties

  • If a convict cannot pay a fine, he/she may have to suffer subsidiary imprisonment.

7. Special Penal Laws and Their Interaction With RPC Principles

  • Special Penal Laws typically carry their own penalties and definitions.
  • In some instances, the principles of the Revised Penal Code (such as mitigating and aggravating circumstances) do not apply or apply only suppletorily.
  • Example: Offenses under Republic Act No. 9165 (Comprehensive Dangerous Drugs Act of 2002) have distinct rules on penalties, non-bailable offenses for large quantities, etc.

8. Key Constitutional Safeguards in Criminal Prosecution

8.1 Right to Speedy Trial

  • Article III, Section 14(2) also implies a right to a speedy trial.
  • Delay must not be vexatious, capricious, or oppressive.

8.2 Right to Public Trial

  • Trials are generally open to the public to ensure transparency, though exceptions exist (e.g., cases involving minors or national security).

8.3 Right to Be Informed of the Nature and Cause of Accusation

  • Ensures the accused can prepare an adequate defense.

8.4 Right Against Cruel, Degrading, or Inhuman Punishment

  • Punishments must not be excessive or disproportionate.

9. Burden of Proof and Quantum of Evidence

9.1 Burden of Proof

  • On the prosecution to prove the guilt of the accused beyond reasonable doubt.

9.2 Reasonable Doubt

  • If doubt remains after considering all the evidence, the accused must be acquitted.
  • This principle ensures the protection of innocent individuals.

10. Enforcement and Implementation

10.1 Role of Law Enforcement Agencies

  • The Philippine National Police (PNP), National Bureau of Investigation (NBI), and other specialized agencies enforce criminal laws and gather evidence for prosecution.

10.2 Prosecutorial Discretion

  • The Office of the City/Provincial Prosecutor evaluates complaints, determines probable cause, and files charges in court.

10.3 Trial Courts

  • Regional Trial Courts (RTC) have jurisdiction over most criminal cases; MTCs handle less grave offenses.

10.4 Appellate Review

  • Decisions of the trial courts can be reviewed by the Court of Appeals and ultimately by the Supreme Court.

11. Practical Implications of These Fundamental Principles

  1. Protection of Rights: The principles enshrined in the Constitution provide the accused with protections that ensure fairness and justice (e.g., presumption of innocence, right to counsel).
  2. Legal Certainty: The principle of legality (nullum crimen, nulla poena sine lege) ensures that citizens know what acts or omissions are punishable.
  3. Fair Application of the Law: Courts are mandated to apply laws strictly and, in case of ambiguity, interpret them in favor of the accused.
  4. Balancing State Interests and Individual Liberties: Criminal laws protect society from wrongful acts while safeguarding individuals against abusive prosecutions.

12. Summary

The fundamental principles of Philippine criminal law stem from constitutional guarantees, codified rules in the Revised Penal Code, and jurisprudence. Key doctrines such as legality, prospectivity, generality, territoriality, mens rea, and the constitutional rights of the accused form the backbone of a system designed to penalize wrongful acts while ensuring fairness and justice.

A clear understanding of these principles is indispensable not just for legal practitioners but also for law enforcement officers, policymakers, and the public at large. They ensure that the exercise of the State’s power to punish is always kept within the bounds of due process and respect for individual rights.
