Criminal Law in Türkiye
Criminal proceedings affect some of the most fundamental rights of an individual, including liberty, reputation, and ability to travel. Whether the matter involves a minor offense, a complex financial crime, or a case with international implications, the Turkish criminal justice system operates through strict procedural rules that leave little room for error. Early and informed legal support is often decisive in the outcome of a case.
Legal Istanbul defends clients' rights throughout criminal investigations and proceedings, combining procedural precision with strategic defense planning.
Key Regulatory Framework
Criminal law in Türkiye is governed by a comprehensive legal framework:
- Turkish Penal Code (Law No. 5237) – Primary source of criminal offenses and sanctions
- Code of Criminal Procedure (Law No. 5271) – Rules governing investigations, trials, and appeals
- Law on the Execution of Sentences (Law No. 5275) – Rules on enforcement and conditional release
- Public Prosecutor's Offices, Criminal Courts, and Courts of Appeal – Institutions handling each stage of the process
Stages of Criminal Proceedings
Turkish criminal procedure follows a structured process, and each stage presents specific rights and risks:
- Investigation Phase – Led by the public prosecutor, including statements, evidence collection, and possible detention
- Indictment and Trial Phase – Formal charges, hearings, and presentation of defense before the competent court
- Appeal and Cassation – Review by regional courts of justice and, where applicable, the Court of Cassation
- Execution Phase – Implementation of final decisions, including imprisonment or alternative sanctions
- Constitutional and International Remedies – Recourse to the Constitutional Court and relevant international mechanisms
Legal Istanbul supports clients at each of these stages with tailored defense strategies.
