The offense of membership in a terrorist organization under the Turkish Penal Code No. 5237

The offense of Armed Organization is regulated under Article 314 of the Turkish Penal Code No. 5237, within the Fifth Chapter titled "Offenses Against the Constitutional Order and Its Functioning", which is part of the Fourth Section titled "Offenses Against the Nation and the State, and Final Provisions." Pursuant to this provision, the establishment and leadership of an armed organization with the aim of committing crimes listed under the Fourth Chapter titled "Offenses Against State Security" and the Fifth Chapter titled "Offenses Against the Constitutional Order and Its Functioning" within the same section of the Penal Code are defined as independent criminal offenses. The concept of "weapon" is explained in Article 6 of the Turkish Penal Code, which outlines definitions. This explanation is not exhaustive. According to the provision, any tool or instrument suitable for use in attack or defense falls within the scope of the term "weapon." The offense of armed organization constitutes a specific type of organizational crime. It differs in key respects from the general offense of forming an organization with the purpose of committing crimes, which is regulated under Article 220 of the Turkish Penal Code. The first key distinction is that the organization in question must be armed. The second is that the armed organization must have been established with the aim of committing crimes stipulated under the chapters "Offenses Against State Security" and "Offenses Against the Constitutional Order and Its Functioning". In this thesis, which focuses on the offense of "Armed Organization" as regulated under Article 314 of the Turkish Penal Code, the offense has been analyzed using the crime analysis method, based primarily on Law No. 5237, alongside scholarly opinions in Turkish legal doctrine and judicial decisions. Controversial and problematic areas have been identified, and personal evaluations and solution proposals have been presented accordingly.
