In this article, the problem of terrorism is discussed in view of the peculiarities of legal nature. The phenomenon of terrorism is being analyzed by scientists in the political, economic, socio-psychological point of view and more attention is paid to the legal theoretical characteristics of this phenomenon. A more detailed analysis of terrorism in the article shows that use of concept of terrorism, regardless of reasons for this, makes the fight against terrorism an ideological tool, posed together as a growing threat to human rights. Furthermore, this article analyzes the reasons of terrorism and provides tendencies for further development of global terrorism. When there is no clear definition of terrorism and its causal relations are acceptable to all, questions concerning the scope of the fight against terrorism arise. In this case, we cannot be sure that modern democratic countries use the correct definition of terrorism in all cases and do not violate the human rights when fighting against terrorists. Even more doubts about the actions of democratic countries participating actively in fight against terrorism arise. The uncertainty of terrorism concept is being used to conceal violations of the human rights.
The objective of the research is to define the development of constitutionalism and socio-cultural challenges related to the formation process of the European Union’s legal identity. To achieve this goal, the concept of constitutionalism and its changes during the period of the European Union’s development are examined. Tendencies of the European Union Member States’ constitutionalism process are analysed and socio-cultural tensions of the formation of the contemporary European Union’s legal identity, which arise between security and freedom, order and justice and government and society are identified. The article states that the sustainability of public democratic processes and the functioning of the European Union is possible only if the constitutional values are protected. The reseach also reveals that the further evolution of European constitutionalism and legal identity still needs to enhance the development of the rules which could influence the creation and activities of the independent, self-governing EU’s political community.
