Nature and Effect of Prescription of Crimes
Prescription of crimes is the extinction of the State's right to prosecute because the period fixed by law for commencing or maintaining the criminal action has lapsed. It is a mode of total extinction of criminal liability because, once completed, the accused may no longer be convicted for the offense, regardless of the apparent strength of the evidence.
The doctrine rests on two connected ideas: the State must act with reasonable promptness in enforcing penal laws, and the accused should not be exposed indefinitely to a criminal charge when evidence may have disappeared, memories may have faded, and the community's penal interest has become stale.
Prescription of the crime is different from prescription of the penalty. Prescription of the crime operates before final judgment and bars prosecution; prescription of the penalty operates after final judgment and bars enforcement of the sentence. The former concerns the criminal action, while the latter concerns execution of the punishment already imposed.
Prescription is also distinct from delay amounting to denial of the constitutional right to speedy disposition or speedy trial. Prescription is measured by statutory periods; speedy disposition and speedy trial depend on the reasonableness of delay under the circumstances. A prosecution may be timely under prescription rules but still vulnerable to a constitutional delay objection, and a prosecution may be free from unconstitutional delay but barred by prescription.
Governing Periods Under the Revised Penal Code
For felonies punished under the Revised Penal Code, the prescriptive period depends primarily on the penalty prescribed by law for the offense charged, not on the penalty actually imposed after trial. The controlling penalty is the legal penalty attached to the felony as properly alleged, taking into account the stage of execution and the nature of the felony charged when these affect the penalty provided by law.
| Felony or penalty class | Prescriptive period |
|---|---|
| Felonies punishable by death, reclusion perpetua, or reclusion temporal | Twenty years |
| Felonies punishable by other afflictive penalties | Fifteen years |
| Felonies punishable by correctional penalties, except arresto mayor | Ten years |
| Felonies punishable by arresto mayor | Five years |
| Libel and other similar offenses | One year |
| Oral defamation and slander by deed | Six months |
| Light offenses | Two months |
The period is fixed by the classification of the offense as punished by law. When the law prescribes imprisonment and fine, the imprisonment usually supplies the controlling classification because it is the principal punitive measure. When the offense is punishable only by fine under the Code, the fine is classified by its statutory amount as afflictive, correctional, or light, and the corresponding prescriptive period follows.
When the charge is for an attempted or frustrated felony, prescription is determined by the penalty legally prescribed for that stage, not by the penalty for the consummated felony. When the charge is for a complex crime, prescription follows the penalty prescribed for the complex crime as a single punishable offense. When the facts disclose separate offenses instead of a complex crime, each offense has its own prescriptive period.
Qualifying circumstances affect prescription when they change the legal identity and penalty of the offense, such as when killing is alleged and proved as murder rather than homicide. Ordinary aggravating or mitigating circumstances do not usually control prescription because they affect the period or degree of the imposable penalty after liability is established, not the basic statutory classification of the crime for prescription purposes.
For felonies by imprudence or negligence, the prescriptive period is based on the penalty prescribed for the quasi-offense charged. The resulting injury or damage matters because it determines the penalty for the negligent act, but the charge remains negligence or imprudence rather than the corresponding intentional felony.
Special Laws and Ordinances
When an offense is punished by a special law, the special law's own prescriptive period controls. If the special law is silent, Act No. 3326 supplies the default periods for offenses penalized by special acts and for violations of municipal ordinances.
| Offense under a special act or ordinance | Default prescriptive period |
|---|---|
| Offense punished only by a fine, or by imprisonment for not more than one month, or by both | One year |
| Offense punished by imprisonment for more than one month but less than two years | Four years |
| Offense punished by imprisonment for two years or more but less than six years | Eight years |
| Offense punished by imprisonment for six years or more | Twelve years, unless another law provides a different period |
| Violation of a municipal ordinance | Two months |
The Revised Penal Code governs felonies defined and punished by the Code. Act No. 3326 generally governs offenses created by special penal statutes when those statutes do not provide their own periods. A statute may expressly make an offense imprescriptible or prescribe a period longer or shorter than the default period; that specific legislative choice prevails over the general rule.
For special laws, the inquiry begins with the statute creating the offense. Some special laws define the prescriptive period, some adopt periods by reference to the penalty, and some are silent. The court should not import Code periods into a special-law offense when Act No. 3326 or the special law itself provides the applicable rule.
When a special law punishes an act by both imprisonment and fine, the term of imprisonment ordinarily determines the default period under Act No. 3326. When it punishes the act only by fine, the one-year default applies unless the statute fixes another period.
Commencement of the Prescriptive Period
For Code felonies, prescription generally begins to run from the day the crime is discovered by the offended party, the authorities, or their agents. Discovery, not mere commission, is the decisive starting point when the crime was concealed or could not reasonably have been known at the time it was committed.
If the offense is open, public, and immediately known to the offended party or authorities, the date of commission and the date of discovery ordinarily coincide. If the offense is secret, falsified, hidden through fraud, or discoverable only after investigation, prescription begins when the relevant person or authority actually or legally discovers the criminal act.
Discovery means knowledge of facts sufficient to indicate that a crime has been committed and that prosecution may be initiated. It does not require complete proof of guilt, final audit findings, or certainty as to every detail, but it requires more than suspicion unsupported by facts identifying the criminal nature of the act.
For continuing offenses, the period begins only when the criminal conduct has ceased or when the last essential act has been committed. The continuing effects of a completed offense do not by themselves make the offense continuing; the crime must involve a continuing unlawful act, omission, or state of affairs made punishable as such by law.
For special-law offenses under Act No. 3326, the period generally begins on the day of commission if the offense was known. If the offense was not known at the time of commission, the period is reckoned from discovery, and a legally instituted proceeding for investigation and punishment interrupts the running of the period.
Interruption and Suspension
Prescription is interrupted when proceedings are instituted against the offender. For offenses requiring preliminary investigation, the filing of a complaint with the office authorized to conduct preliminary investigation interrupts prescription because it commences the official process for determining probable cause and pursuing punishment.
For offenses filed directly in court, the filing of the complaint or information in court interrupts prescription. The important point is that the proceeding must be directed toward the investigation or punishment of the offense, not merely toward civil recovery, administrative discipline, or private demand.
A complaint filed with the barangay for conciliation may interrupt prescription for offenses covered by barangay conciliation rules, but the interruption is limited by the governing barangay justice provisions. The rule prevents the mandatory barangay process from consuming the short prescriptive periods of minor offenses while still preserving the statutory limits on interruption.
Prescription begins to run again when the proceeding terminates without conviction or acquittal, or when the proceeding is unjustifiably stopped for a reason not imputable to the accused. A dismissal that does not amount to an adjudication of guilt or innocence may allow the period to resume, subject to the remaining unexpired portion of the prescriptive period.
The period does not run while the offender is absent from the Philippines. Absence matters because the State's ability to proceed against the offender is impaired, and the accused should not benefit from the running of time while beyond the effective reach of local criminal process.
Delay attributable to the accused does not ordinarily support prescription. If the proceedings are stalled because the accused is evading arrest, seeking postponements, pursuing dilatory motions, or otherwise causing the delay, the accused cannot rely on that delay as the basis for extinction of criminal liability by prescription.
Institution of Proceedings
The phrase institution of proceedings is understood in a practical and functional sense. It includes the commencement of the criminal process before the proper officer or tribunal authorized to act on the offense, so long as the proceeding is aimed at investigation and punishment.
For offenses subject to preliminary investigation, a complaint-affidavit filed with the prosecutor, the Ombudsman when it has jurisdiction, or another officer legally authorized to conduct preliminary investigation may interrupt prescription. The interruption is justified because the complainant has invoked the machinery of criminal prosecution within the period fixed by law.
An administrative complaint does not automatically interrupt criminal prescription. It interrupts only when the proceeding is also the legally recognized mode of initiating criminal investigation or when the law treats that filing as part of the criminal process. Otherwise, administrative accountability and criminal liability remain distinct.
A civil action, demand letter, audit referral, media report, or internal company investigation does not interrupt prescription by itself. These may supply evidence of discovery or identify the persons involved, but interruption requires the institution of a proceeding contemplated by criminal law or procedure.
If a complaint is filed before an officer or body with no authority to investigate or prosecute the offense, interruption is not automatic. The filing must be before a forum that the law recognizes as capable of initiating the criminal process for that offense, or it must at least be transmitted into the proper criminal proceeding within the period required by law.
Dismissal, Refiling, and Effect of Prior Proceedings
When prescription has already run before the criminal action is instituted, subsequent filing cannot revive the State's right to prosecute. A prescribed offense is not cured by amendment of the information, by later discovery of stronger evidence, or by the accused's participation in trial.
When a timely filed proceeding is dismissed without conviction or acquittal, the prescriptive clock resumes from the point where it was interrupted. The State does not receive an entirely new full period unless the governing law so provides; it generally retains only the unexpired balance.
If dismissal amounts to an acquittal or otherwise places the accused in jeopardy, refiling may be barred by double jeopardy rather than merely by prescription. If dismissal is without prejudice and no jeopardy attaches, refiling may still be barred if the remaining prescriptive period has already lapsed.
An amended information that merely corrects, clarifies, or amplifies the same offense relates to the original timely filing for prescription purposes. An amendment that charges a different offense, especially one with different essential elements or a graver penalty, must be tested against prescription as to that offense.
Misdesignation of the offense is not controlling; the allegations of ultimate facts determine the offense charged. Prescription should therefore be assessed from the facts alleged and the penalty legally attached to those facts, not from an inaccurate label used by the prosecution.
Procedural Use of Prescription
Prescription may be raised through a motion to quash when the facts alleged in the information and matters properly considered by the court show that the offense has prescribed. The ground is the extinction of criminal liability or the extinction of the criminal action before trial.
If prescription is not apparent on the face of the information, the accused may raise it as a defense and present evidence on the date of commission, date of discovery, date of filing, interruption, suspension, and other facts necessary to compute the period. The court may deny a motion to quash without prejudice to proving prescription at trial when factual matters remain disputed.
Once the relevant dates are established, prescription is a question of law. The court must apply the statutory period to the proved or admitted facts and dismiss the criminal action when the State's right to prosecute has been extinguished.
Because prescription affects the State's authority to punish, it may be considered even at a late stage when the record clearly shows that the offense has prescribed. However, a party invoking prescription must still point to facts from which the court can compute the period, unless those facts are already admitted or judicially noticeable.
The prosecution may defeat a prescription defense by showing timely institution of proceedings, lawful interruption, suspension due to the offender's absence, delayed discovery, or that the applicable period is longer than the accused claims. The accused may defeat interruption by showing that the proceeding was not legally instituted, was directed at a different offense, or was stopped for a reason not imputable to the accused after the period had resumed.
Computation Principles
The computation starts with the legally relevant date of discovery or commission and ends with the valid institution of proceedings. The period is measured by the prescriptive period attached to the offense, and the court must account for any interval during which prescription was interrupted or did not run.
In offenses involving several acts, the court should identify the moment when all elements of the crime were present. A crime cannot prescribe before it is complete, and the period cannot begin before the offense is discoverable in the legally relevant sense.
In conspiracy, prescription is generally computed from the commission or discovery of the offense committed pursuant to the conspiracy, not from the earlier agreement alone, unless the agreement itself is independently punishable. The conspiratorial character of liability does not erase the need to identify the offense and the date it became complete.
In crimes involving public documents, fraud, public funds, or official acts, discovery may occur through audit, official examination, registration, inspection, or disclosure, depending on when the offended party or competent authority acquired enough facts to identify the criminal act. Formal completion of an audit is not always required if the offense was already known earlier, but mere rumor is not enough to start the clock.
For offenses with short periods, such as light offenses, oral defamation, slander by deed, and ordinance violations, prompt filing in the proper forum is essential because even brief delay can extinguish criminal liability. The shortness of the period reflects the law's judgment that minor offenses should be prosecuted quickly or not at all.
Result of Complete Prescription
Once prescription of the crime is complete, the criminal action must be dismissed and the accused cannot be convicted of the prescribed offense. The extinguishment is substantive because the right of the State to punish has ended, not merely because a pleading rule was missed.
Prescription of the crime does not necessarily settle all civil consequences of the act. Civil liability may be governed by separate rules when it arises from sources other than the criminal conviction, such as contract, quasi-contract, law, or quasi-delict. The criminal court's dismissal on prescription should therefore be distinguished from an adjudication that no civil wrong occurred.
The benefit of prescription applies only to the offense that has prescribed. If the same facts also constitute a separate offense with a different prescriptive period and that offense is properly charged within time, prosecution for the unprescribed offense may proceed, subject to rules on double jeopardy, due process, and sufficiency of allegations.
Prescription implements finality in criminal law. It balances the public interest in punishment with the accused's interest in repose, and it requires prosecutors, offended parties, and courts to treat time limits as part of the substantive boundaries of criminal liability.
