The article presents the administrative and legal regulations for the organization of public assemblies in relation to the state’s competence in the field of security logistics. The aim of the article is to indicate the legal possibilities of the state in the field of organizing public assemblies. The research problem was formulated in the form of a question: How do public authorities performing tasks in the field of state security logistics fulfill the constitutional norm granting a person the freedom of assembly. The research hypothesis that has been verified is: The public authority has a wide range of possibilities both in terms of organizing public assemblies and ensuring their safety. The period between its notification and its holding is not without significance for the security logistics of a public assembly. Considerations on the topic will be based on the available literature on the subject, normative acts, personal observations, as well as other sources of information illustrating the course and control of public assemblies. The assessment of local government authorities evaluating the registered manifestations, as well as their applications for permission to hold an assembly or its prohibition, will also be of key importance for the consideration of the subject. Conclusions from the conducted research were formulated in the last part of the article. The most important conclusions include that Public authorities have a wide range of competences both in terms of organization and the ability to ensure public security. In addition, the amended Act on Public Assemblies introduced in 2015 significantly contributed to increasing the powers of local governments.
