How Is Sentence Execution Calculated for Offenses Against Sexual Inviolability? A Guide to Parole and Probation in Turkey

Once a criminal court judgment becomes final, the most concrete question facing the convicted person and their relatives is: "how long will this sentence actually take to serve?" Under Turkish sentence-execution law, how much of the sentence is actually spent in prison depends on special ratios that vary by the type of offense. Offenses committed against sexual inviolability form a category of their own, with rules that depart from the general regime. In this article, we examine — in a calm and technical framework — which legislative provisions govern the execution calculation for this category of offenses. Our aim is to explain the legal framework and the rights involved clearly to anyone seeking to understand the process.

The Legal Issue

The questions that must be answered in an execution calculation are these:

• What is the ratio required for conditional release (parole) in offenses against sexual inviolability, and how does it differ from the general regime?
• How does probation (denetimli serbestlik) operate for this type of offense?
• How do recidivism (repeat-offender status) or the 2023 legislative amendment affect this calculation?

What Do the Legislation and the Yargıtay (Court of Cassation) Say?

The conditional release ratio differs from the general rule. Under Article 107/2-d of the Law on the Execution of Sentences and Security Measures No. 5275, for offenses committed against sexual inviolability (excluding Turkish Penal Code (TCK) Article 102/2), the conditional release ratio is 2/3. This ratio is higher than the general 1/2 ratio applied to many types of offense and reflects the legislature's approach to this category of crime.

The calculation is made through a simple proportion. For example, the 2/3 ratio is applied to the total prison sentence expressed in months to find the minimum period the convicted person must spend in prison. Any time already spent in pre-trial detention is deducted from this period.

Probation is assessed separately. Under Article 105/A of Law No. 5275, one year (12 months) before the conditional release date, the convicted person may benefit from probation if they meet the conditions. In that case, the time the person must actually spend in prison is 12 months less than the period required for conditional release.

The 2023 amendment created an exception for this group of offenses. Under provisional Article 10 of Law No. 5275, offenses committed against sexual inviolability were excluded from certain execution advantages introduced in 2023. Those convicted of offenses in this category therefore cannot benefit from those general advantages.

Recidivism raises the ratio. The calculation is made on the assumption that the convicted person is not a recidivist (repeat offender). If, under Article 58 of the Turkish Penal Code (TCK), the court has ordered the application of the execution regime specific to recidivists, the execution ratio rises from 2/3 to 3/4, and the probation and conditional release periods change to the convicted person's disadvantage.

The good-conduct requirement applies at every stage. To benefit from conditional release and probation, the prison administration and observation board must separately determine that the convicted person has shown "good conduct" in prison. This is not an automatic process.

Yargıtay (Court of Cassation) practice confirms these calculation principles. In numerous decisions of the 9th Criminal Chamber of the Yargıtay concerning sexual assault offenses (for example E. 2021/17267, K. 2024/7969, dated 2024), judgments applying aggravated forms and discretionary reductions have been upheld; these decisions show that the determination of the base sentence and the reduction calculations are subject to review.

Points to Watch

• Calculate the total sentence correctly in months. Execution calculation is an area prone to year-month-day confusion; a professional check is important.
• Clarify your recidivism status. This can raise the execution ratio from 2/3 to 3/4 and significantly extend the time to be spent in prison.
• Have pre-trial detention periods deducted. Time spent in detention before the judgment became final must be deducted from the calculated prison term.
• Research the conditions for transfer to an open prison. The specific regulation provisions on this matter may require a certain portion of the total sentence to be served in a closed institution.
• Follow the good-conduct assessment. Since conditional release and probation depend on a separate assessment by the administration, this process should be monitored in advance.

Conclusion: What Should You Do?

Execution calculation for offenses committed against sexual inviolability is an area that differs from the general regime and involves technical details. The 2/3 conditional release ratio, the exceptions introduced by the 2023 amendment and the effect of recidivism are all factors that can lead to loss of rights if the calculation is not done correctly. For an accurate and up-to-date calculation regarding the execution of a final judgment, obtaining current information from a lawyer experienced in sentence-execution law or from the execution prosecutor's office is important for managing the process correctly.
