Short answer

Turkish criminal law is structured around Penal Code 5237 (offenses and penalties), Code of Criminal Procedure 5271 (investigation and prosecution) and Execution Law 5275. Core principles include the presumption of innocence, the duty to gather evidence both for and against the suspect (CMK art. 160), right to counsel (art. 147) and nullum crimen sine lege (Penal Code art. 2).

Introduction to Criminal Law

Criminal law is one of the most critical branches of law that regulates criminal acts and their sanctions, directly affecting personal freedom. Under Turkish Penal Code No. 5237 and Criminal Procedure Law No. 5271, we defend our clients' rights most effectively in all processes from investigation to enforcement law.

⚠️ Critical Information

Legal assistance is a constitutional right and should be exercised from the beginning of the investigation. The first statement given during detention directly affects the course of the case.

Criminal Case Defense

As criminal defense attorneys, we undertake the duties of protecting the legal rights of suspects or defendants, monitoring the evidence collection process, being present during statements and interrogations, objecting to arrest and detention decisions, and providing effective defense throughout the prosecution process.

Investigation Phase

Investigation is a critical process that begins with learning of the suspicion of crime and ends with the acceptance of the indictment. The statements given, evidence collected, and procedures performed at this stage directly affect the course of the case. Detention period is 24 hours for individual crimes and can be extended up to 4 days for collective crimes. Legal assistance is a constitutional right and should be exercised from the beginning of the investigation.

Prosecution and Trial

In the prosecution phase that begins with the acceptance of the indictment, participation in hearings, cross-examination of witnesses and complainants, evaluation of evidence, and presentation of legal defense are critically important. At this stage, all evidence in favor of the defendant must be effectively presented to the court.

Major Crime Types and Penalties

Crime TypePenalty Range
Intentional Injury1-3 years imprisonment
Threat6 months - 2 years imprisonment
Insult3 months - 2 years or judicial fine
Theft1-3 years imprisonment
Fraud1-5 years imprisonment
Drug (Use)2-5 years or treatment
Drug (Trafficking)10-20 years imprisonment

Detention and Appeal

Detention occurs by judge's decision in case of strong suspicion of crime and detention reasons (escape, tampering with evidence). There is a right to appeal the detention decision, and the appeal must be filed within 7 days from notification. Release can be requested if detention exceeds reasonable time.

Legal Remedies

Appeal to Regional Court (İstinaf) and Supreme Court (Temyiz) can be made against local court decisions. Appeal period is 7 days for regional court and 15 days for Supreme Court from learning the decision. Extraordinary legal remedies include Chief Public Prosecutor's Objection and Retrial.

Enforcement Law

In the enforcement process that begins with the finalization of the conviction decision, we provide legal support on issues such as conditional release, probation, sentence deferral, and serving sentences in installments. We also stand by our clients in good behavior reduction and transition to open prison processes.
