§ 75 of the Turkish Penal Procedure Code and § 81a of the German Penal Procedure Code regulate taking of a blood sample from the body of the suspect or the accused. Even though the Turkish regulation is similar to the German regulation, there are important differences concerning the issue of order competence. In both systems of justice the competence of the judge is the rule. But exceptionally the prosecution is also competent to order taking of a blood sample. According to the German regulation beside of the prosecution the police is also secondarily authorized. While the German Penal Procedure Law provides that the order is legally superfluous in case of consent of the person concerned, in Turkish Penal Procedure Law a consent doesn’t take effect to the requirement of an order. Especially within the framework of traffic controls the consent of the person concerned is to handle with care if he stays under alcohol or narcotic substances. That’s why German law makes high demands on the consent. However the Turkish doctrine requires partially consent of the person concerned in spite of the existence of an order. This shows that the Turkish regulation makes great demands on taking blood and that this regulation is “safer”.
