Limitation periods in Turkish criminal law serve a practical purpose: after sufficient time has passed, the state’s power to prosecute or enforce a sentence must yield to legal certainty. Two separate institutions govern this — the prosecution limitation period (dava zamanaşımı), which bars bringing a case, and the enforcement limitation period (ceza zamanaşımı), which bars executing a sentence already given. They operate differently and produce different outcomes.
Prosecution Limitation (Dava Zamanaşımı)
The prosecution limitation period begins when the offence is committed. Once expired, the criminal case must be dismissed — the prosecution cannot proceed regardless of how strong the evidence is.
The period is determined by the statutory maximum sentence for the offence:
| Statutory Maximum Penalty | Limitation Period |
|---|---|
| Aggravated life imprisonment | 30 years |
| Life imprisonment | 25 years |
| More than 20 years | 20 years |
| 5–20 years | 15 years |
| 1–5 years | 8 years |
| Less than 1 year, or fine only | 4 years or shorter |
The qualifying penalty is the maximum in the statute, not the sentence actually expected for the individual case.
Enforcement Limitation (Ceza Zamanaşımı)
Where a sentence has been handed down but is not yet being executed — because the convicted person has fled, or enforcement was deferred — the enforcement limitation period runs from the date the sentence became final. Once expired, the sentence can no longer be enforced. However, the conviction itself remains on the criminal record. Enforcement limitation extinguishes the right to punish, not the fact of the conviction.
The enforcement periods are generally longer than the prosecution periods, scaled to the length of the sentence.
Interruption and Suspension
Interruption (Kesilme)
Certain events reset the limitation clock entirely — the period begins running afresh from zero. Interrupting events include:
- Arrest of the suspect
- Filing of the indictment
- A court hearing at which the accused is present
- A conviction, even if subsequently appealed
One critical constraint: following interruption, the new period may not exceed one and a half times the original period. This cap prevents perpetual extension through repeated interruptions.
Suspension (Durma)
Suspension pauses the clock without resetting it. Time already elapsed is preserved; the period resumes when the reason for suspension ends. Grounds for suspension include:
- The suspect cannot be held criminally responsible due to a mental condition
- The resolution of a preliminary or prejudicial legal question is pending
- The accused is abroad and cannot be brought before the court
What Expiry Means in Practice
Prosecution limitation: the court must dismiss the case. If the limitation is reached mid-trial, the proceedings terminate without an acquittal — which means no criminal conviction but also no formal finding of innocence. Civil claims arising from the same events may remain available.
Enforcement limitation: the sentence cannot be executed, but the conviction stands. The person cannot be imprisoned or fined under that judgment, but the criminal record entry remains.
No limitation for certain offences: genocide, crimes against humanity, and certain war crimes are not subject to any limitation period under Turkish law and international treaties.
Frequently Asked Questions
The offence was committed years ago. Has the prosecution limitation expired? It depends on the statutory maximum for the offence — not the sentence you expect to receive. Identify the relevant article of the Turkish Criminal Code, find the statutory maximum penalty, and match it to the table above. Bear in mind that if the limitation was interrupted by an arrest or indictment, the period may have restarted.
The trial went on for many years. Can the case be dismissed for exceeding the limitation period? Yes. Even if a case has been in progress for a long time, the limitation period continues to run. If the proceedings drag on and the period expires before a final conviction, the case must be dismissed. Defense lawyers track this and can raise the issue at any stage of proceedings.
I was convicted years ago but the sentence was never enforced. Is it still valid? Check the enforcement limitation period for the type and length of sentence. If that period has expired, you can no longer be required to serve the sentence. The conviction, however, remains on your record and does not disappear.
Does an arrest always reset the limitation clock? Yes — arrest is one of the events that interrupts the prosecution limitation period and restarts it from zero, subject to the one and a half times cap. This is why early arrest by the authorities often effectively extends the viable prosecution window.
