U radu se razmatra složenost pravnog okvira za borbu protiv terorizma na univerzalnoj razini i na razini Europske Unije te njihov međuodnos.

Jednako tako, razmatra se pravni položaj međunarodnopravnih instrumenata UN-a za borbu protiv terorizma u Europskoj Uniji.This paper considers the complexity of the legal frameworks in the fight against terrorism at a universal level and at the level of the European Union, as well as their mutual relationship.
