KYOK in Turkey: short answer

A victim harmed by the alleged offence may object to a Turkish prosecutor's decision of no prosecution, commonly called KYOK, within two weeks after service. Under CMK Article 173, the petition goes to the criminal peace judgeship located at the assize-court centre for the judicial district in which the issuing prosecutor works.

Scope of review: A foreign complainant challenging a decision of no prosecution, known as KYOK, through the CMK Article 173 two-week objection with specific investigative requests.

Law checked through: 6 September 2026. Responsible lawyer: Attorney Emirhan Keskin.

KYOK in Turkey

A KYOK objection is different from reporting a new offence, objecting to an administrative decision, suing for damages or appealing an acquittal after trial. It reviews whether prosecution should follow the investigation; it does not convict the suspect or award compensation. A decision transferring the file or declaring lack of venue may require a different remedy.

The judgeship may reject the objection and charge the objector with expenses, order completion or expansion of investigation, or sustain it so that the prosecutor files an indictment. A sustained objection does not predetermine guilt. After rejection, reopening on the same event ordinarily requires new evidence and the statutory procedure, so missing readily available evidence at this stage is costly.
