The scientific study deals with the issue of police interventions into fundamental rights and freedoms as a result of police activities connected to the execution of tasks and duties of police officers, and also with other provisions of the Act on the Police Force. The authors consider the rule of law to be synonymous with constitutional or legitimate governance and which also characterises the exercise of state authority on the basis of constitutionally issued laws. The authors associate police interventions with the protective function of the state, establish conditions for interference with fundamental rights and freedoms from the perspective of police activity which compliance with, or breaching of, indicates whether the particular rights and freedoms are violated or not by the intervention. Subsequently, the authors identified the concepts of prevention and prophylaxis, which they interpret on the basis of chosen international scientific results and conclusions.
