Przyłączenie Krymu przez Rosję w świetle prawa międzynarodowego

The article describes the most important international law issues related to the annexation of the Crimea by the Russian Federation. The first part of the text concerns with the infringements of the international law made by Russia (infringement of the principle pacta sunt servanda, the principle of non-intervention and the principle of the prohibition of aggression). The second, essential part of the text concerns the inadmissibility of self-determination of people in the case of the Crimea. Russian involvement in the Crimea results the illegality of self-determination in this case. It is also impossible because the case of Crimea does not meet the required conditions. This causes the inadmissibility of the secession of this territory.
