Criminal law regulates acts that constitute criminal offenses and the sanctions applicable to such acts. This field addresses investigation and prosecution procedures, the rights of suspects and defendants, and procedural rules governing criminal proceedings.

During the investigation phase, procedures such as taking statements, collecting evidence, detention, and arrest may be conducted. In the prosecution phase, matters including the examination of the indictment, court hearings, and the issuance of judgments are considered. Each stage of the process is evaluated in accordance with applicable legislation.

Criminal law also includes mechanisms such as reconciliation, effective remorse, and suspension of the pronouncement of judgment. These mechanisms are assessed based on the nature of the case and the statutory requirements.

Criminal law matters involving individuals residing abroad and relating to acts committed in Türkiye or subject to Turkish criminal law may require particular legal consideration. Such proceedings are carried out in accordance with Turkish legislation.
