Criminal Statute of Limitations

What Is the Criminal Statute of Limitations?

The criminal statute of limitations is the time period within which a criminal case must be filed. Once the period expires, prosecution is barred — even with clear evidence, the prosecutor or victim can no longer file the case, and the matter is extinguished.

This principle reflects the legal idea that "justice should not be delayed indefinitely." Allowing prosecution forever would leave evidence and witness memories degraded, undermining fair trial. Old offenses also pose less danger, reducing the need for punishment.

Applicable Law

The Thai Criminal Code addresses this in Book 1, Title 6 (Sections 95–101), which distinguishes:

• Limitation for prosecution (Section 95) — Time within which a case must be filed, counted from the date of the offense.
• Limitation for compoundable offenses (Section 96) — Special period for offenses requiring a victim's complaint.
• Limitation on enforcement of penalty (Section 98) — After judgment but before execution of sentence.

Limitation Periods Under Section 95

The limitation period is calculated from the maximum penalty for the offense, not the actual sentence imposed.

Examples: Intentional murder carries the death penalty, so the limitation is 20 years. Theft carries up to 3 years' imprisonment, so the limitation is 10 years.

Compoundable Offenses (Section 96)

A "compoundable offense" requires the victim's complaint before prosecution can begin. The prosecutor cannot proceed without it, and the case may be terminated if the victim withdraws the complaint.

For these offenses, the complaint period is 3 months from the date the victim learns of the offense and the offender's identity. Failure to complain within 3 months extinguishes the criminal case.

Examples of compoundable offenses:

• Bounced cheque (Cheque Act)
• Defamation (Section 326)
• Fraud (Section 341 — in some forms)
• Embezzlement (Section 352)
• Trespass to dwelling (Section 364)
• Marital rape

Important Distinction

The general "prosecution" limit under Section 95 (e.g., 10 years) runs from the date of offense. The "complaint" limit for compoundable offenses under Section 96 (3 months) runs from when the victim learned of the offense. Both must be satisfied for the case to proceed.

Limitation on Enforcement (Section 98)

If a defendant is convicted but the sentence has not been carried out (e.g., the defendant flees), the sentence must be enforced within these periods:

• Death / life imprisonment / 20+ years — 20 years
• Imprisonment over 7 but not over 20 years — 15 years
• Imprisonment over 1 year but not over 7 years — 10 years
• Imprisonment up to 1 year / fine — 5 years

Beyond these periods, the state cannot enforce the sentence; the defendant is automatically discharged.

Suspension and Tolling of Limitation

Section 95 also defines events that suspend the running of the limitation period:

• Filing of the case — Once filed in court, the limitation stops running.
• Flight from justice — The limitation is tolled while the defendant is at large.
• Issuance of an arrest warrant — In some cases.

These rules prevent defendants from running out the clock by hiding.

Offenses Without Limitation

Special legislation exempts certain offenses from the standard limitations or imposes longer ones:

• Offenses against the monarchy — Some have no limitation.
• Terrorism-related offenses — Governed by special laws.
• Crimes against humanity, genocide — Per international conventions.

Hypothetical Case Studies (Educational)

Case 1 — Theft: Mr. A stole a motorcycle in 2020 (penalty up to 3 years imprisonment → 10-year limitation). The victim files a complaint in 2023, well within the limit. Prosecution may proceed. The limitation expires in 2030.

Case 2 — Bounced cheque: Ms. B learns the cheque bounced on 1 January 2023 (compoundable offense). She files her complaint on 5 May 2023 (4 months later) — past the 3-month complaint period. The criminal case is barred. Only the civil claim, within 1 year, remains.

Case 3 — Flight: Mr. C committed armed robbery in 2010 (15-year limitation). He fled abroad in 2011, suspending the limitation during his flight. He returns to Thailand in 2023. The limitation resumes; prosecution remains possible.

Common Mistakes

• Miscalculating the start date — Some assume limitation runs from when the victim learned, regardless of offense. General offenses run from the date of the act; only compoundable offenses run from discovery.
• Not realizing an offense is compoundable — Missing the 3-month complaint window.
• Assuming filing within limitation guarantees winning — Filing in time is necessary; the merits must still be proven in court.
• Believing a long absence ends the case — Flight tolls the limitation; the suspect does not escape liability.
• Not consulting a lawyer early — Missing the chance to gather evidence before witnesses forget or disappear.

Frequently Asked Questions

From which date is the limitation counted?
Generally from the date the offense was completed. For compoundable offenses, from the date the victim learned of the act and the offender's identity.

Can I file on the very last day of the limitation period?
Yes, but it is risky — any technical issue (missing documents, etc.) may push it past the deadline.

Are limitation periods the same for juvenile cases?
Generally yes, but procedure in juvenile and family courts differs.

Do other laws have different limitations?
Yes — the Narcotics Act, the Anti-Corruption Act, the Anti-Money Laundering Act, and others may have specific limitations. Check with a lawyer for your specific case.

If the victim dies, who can file the complaint?
Heirs or descendants may file the complaint for compoundable offenses within the remaining limitation period.

Conclusion

The criminal statute of limitations is a vital legal mechanism setting time boundaries for prosecution. Victims must complain or file within the period to preserve their rights. Suspects should understand that fleeing does not provide escape — the law tolls the limitation during flight. Early consultation with a lawyer is essential to assess the limitation and plan an appropriate course of action.
