ENThe authors of this research paper analyse the impact of declared state of emergency measures on social relations in the Republic of Lithuania within the entire area at the state border of the Republic of Lithuania with the Republic of Belarus and 5 kilometres inland from the border area from 10 November 2021, 24.00 (midnight). Influx of migration as part of the hybrid attack against the Lithuania, Poland, Latvia supported by the Belorussian authorities in 2021 requires Lithuanian institutions to take immediate coordinated contra measures to stop the hybrid attack on the European Union (hereinafter – the EU). The Republic of Lithuania has 679 kilometres eastern external border of the European Union with the Republic of Belarus. Accordingly, Lithuania is in charge for ensuring protection of the border and as sovereign state has the exclusive and discretionary right to make final decisions in a given situation and employ the best suitable and effective measures to handle threats to the national security. Lithuania declared the state emergency at the border with the Republic of Belarus. The territory which falls under the state of emergency obtained a new legal status and concurrently became the object of the specific legal regulation. Also, this gives rise to several questions. How the new legal status of the given territory impacts the four freedoms of the EU, i.e., the free movement of goods, the free movement of capital, the freedom to establish and provide services, the free movement of persons.It affects many parts of the economic activity, the human behaviour, the status of psychological health, the international cooperation between neighbouring countries and between different players in both countries. This research mainly focuses on the economic part of social relations. The object of the research might seem simple at first sight. However, suppression in economic relations affects both legal and shadow economy, and border crossing procedures and finally it interferes with the communication sphere at trans-border and within the affected territory. Keywords: state of emergency, four freedoms, social relations, human being, economic activity. [From the publication]
