Study of Russian politics Researches the political and legal system and history of the Russian Federation from the point of view of the sociology of law. Based on the publications of Mykola Timashev, he writes that under the facade of "managed democracy" hides a regime of despotic power in a softened form, characteristic of the history of the Russian state. In the article "Russia as a fascist society" he proves that today Russia corresponds to the scientific and sociological criteria of a fascist society.
History of international law In the book "Russian Science of International Law during the First World War" (
Kyiv, 2014) he analyzed international law during the war and criticized the modern Russian doctrine of international law, which after the beginning of the temporary annexation of
Crimea by the Russian Federation turned into propaganda of the
Putin regime.
Views on Russia's aggression against other countries He is the author of numerous articles on the topic of Russian aggression against Ukraine, researches it from the point of view of international law. Justifies the right of the
Crimean Tatar people to self-determination as an indigenous people within
Ukraine. Conducts a critical analysis of the arguments of Russian international lawyers and shows the criminal nature of the annexation of Crimea by Russia. In 2008, in one of his journalistic articles, he interpreted the Russo-Georgian war as Georgian aggression by
Saakashvili's "imperial" regime against South Ossetia, which met the main criteria of statehood, and the Ossetian people themselves had the right, in Merezhko's opinion, to secession. In the same article, he expressed the opinion that Ukraine should recognize the legitimacy of the secession of both
Kosovo and
South Ossetia and
Abkhazia by analogy with the international recognition of Kosovo by most EU countries, as well as the US, Canada and Australia. In 2020, in a conversation with RadioFreeEurope/RadioLiberty, Merezhko stated that Russia, invading the territory of Georgia in 2008 under the guise of peacekeeping, actually carried out an armed aggression against Georgia with the occupation of part of its sovereign territory.
Study of Russia's status in the UN Justified the thesis that Russia, taking the place of the
USSR in the
UN Security Council, thereby clearly violated the UN Charter, since it cannot be considered the same state and the same subject of international law as the USSR; and therefore, from the point of view of international law, Russia cannot be considered a member of the UN.
Participation in international scientific conferences on the Crimea annexation In June 2014, he gave a speech "Ideology of Liberalism and International Law" at a scientific conference at the university of
Tartu (
Estonia), in which he criticized Russia's annexation of
Crimea from the point of view of international law. In September 2014, he gave a speech "The Collapse of the USSR and Territorial Consequences" at the Institute named after Plank in Heidelberg (Germany), in which he showed the illegality of Russia's annexation of Crimea. In December 2014, he spoke at the university of
Helsinki (
Finland) at the "Ukrainian Crisis" seminar with a report in which he presented international legal arguments against Russia's invasion of
Donbas. In March 2015, in
Warsaw, at the conference "The Case of Crimea in the Light of International Law", he raised the question of the forms and mechanisms of Russia's international legal responsibility for aggression against Ukraine. ==Political career==
