Various opinions have been expressed on how law enforcement should be organised. In this context, theses about law enforcement forces being organised together or occurring in different institutions are defended for diverse reasons. However, it is not common to examine this fundamental issue regarding law enforcement from the perspective of constitutional law. This study aims to examine the aforementioned debate from a different perspective by examining some of the decisions of the Constitutional Court during the practices of individual application, which is a tool of the constitutional jurisdiction. As a result of the examination of the individual application decisions, it can be determined that the judicial police could not conduct an adequate and effective investigation of the incidents in which the administrative police officers were suspicious. After discussing these decisions in detail, it is concluded that the separate organisation of the judicial and administrative police will be extremely beneficial in terms of conducting an independent and effective investigation and thus protecting constitutional principles.
