Currently, organ trafficking occupies a leading position among transnational organized criminal groups due to the high demand for illegal services and the relatively low rates of detection of illegal actions by law enforcement agencies. In this context, the purpose of the paper was to conduct a comparative analysis of the foundations of the legal regulation of criminal liability for organ trafficking and trafficking in the Russian Federation, Kazakhstan, and the European Union to form scientifically substantiated conclusions and suggestions for improving existing national legislation. To achieve this purpose, general scientific and special methods were used. The study also uncovers vectors and substantiates the feasibility of implementing EU legislation in the field of organ trafficking and trafficking in the criminal legislation of the Russian Federation and Kazakhstan, predicts the prospects for improving legal regulation on the subject matter and outlined the priority actions of legislative bodies. At the same time, promising areas of research in this matter are the issues of punishability of such acts and the appointment of the appropriate punishment. Furthermore, the creation of a highly regulated transplantation system at the national level was proposed, which is to be managed by a national transplantation authority with broad oversight powers. The creation of such a centralised competent authority will ensure the implementation of the scope of measures that would effectively reduce the risk of organ trafficking and trafficking and protect potential victims.

Convention for the Protection of Human Rights and Fundamental Freedoms simultaneously complements the content of European public order, introducing human rights as a new component and providing two powerful mechanisms for implementing and guaranteeing this order, namely the Convention and a judicial body -the ECtHR. The results obtained allow us to formulate new concepts of unification of terms and approaches to the public order in Europe, which will integrate this region even more into the common legal space and provide the protection of human rights and freedoms at a new, higher level.

Topicality. The relevance of this topic is determined by the study of problematic issues related to the optimization of the activities of national state authorities in the conditions of martial law. The purpose of the article is to highlight the peculiarities of the constitutional and legal regulation of the functioning of the public power mechanism of European states in the conditions of martial law based on the analysis and synthesis of scientific works and constitutional and legal acts regarding the content of special legal regimes that are introduced during crisis situations. Research methods. To achieve the specified goal, a set of methods was used: dialectical (for the objectivity and comprehensiveness of knowledge of state-legal phenomena in foreign countries, taking into account various factors, in development), systemic approach (when considering public authorities as a whole ordered system), formal-legal method (for establishing the content of legal norms and analyzing the practice of their application) and others. The comparative legal method was used as the leading method (to compare the legal and organizational aspects of the functioning of authorities and to develop practical recommendations for improving the activities of public authorities in Ukraine). Results. The constitutional and legal norms regulating the special legal regime (in particular, the martial law regime) in European countries are analyzed, and the key features of the mechanism of public power functioning in emergency conditions are highlighted. It is emphasized that the study of European experience is relevant and appropriate from the point of view of possible further implementation in national legislation. It is noted that special legal regimes are introduced when a certain situation of an extraordinary nature arises in the state, threatening the development of the state and society, the rights and freedoms of citizens. The constitutional and legal institution of the emergency regime is a system of legal norms that establish the grounds and procedure for its introduction, the state authority authorized to introduce it. A special mode of activity of state authorities and local self-governments, enterprises, institutions and organizations is also established. The limits of the special legal regime in time and space are fixed. In the states, temporary changes in the demarcation of competence between the authorities of different levels are usually foreseen. As a rule, executive authorities are temporarily granted certain powers that normally belong to the legislative body, on a clear legal basis. Four variants of implementation of the procedure for the introduction of special legal regimes (in particular, martial law) in the practice of European states are distinguished, which are differed by the degree of involvement of the parliament. The significance of the results. The possible ways and methods of optimizing the activities of the higher state authorities of Ukraine in the conditions of martial law are proposed.

Transplant tourism is a negative consequence of the globalization of society. Trafficking in human organs has reached all countries and threatens their security. This international problem requires a response from states, their legislative institutions and international organizations. The purpose of this article is a comprehensive study and systematization of the norms of international law and national legislation, which determine the legal regime of the circulation of human anatomical materials, as well as the identification of shortcomings in the criminal-legal protection of the field of transplantology in Ukraine and the search for ways to improve domestic criminal legislation in the context of the European integration of our country. Various research methods were used to achieve this goal. In particular, the elements and features of the composition of criminal offenses of the current legislation and the relevant novels were analysed using the dialectical method of cognition. Thanks to the use of the historical method, a number of international legal acts have been established that prohibit the trade in human organs. The dogmatic method made it possible to reveal the actual content of legal norms that regulate the circulation of human anatomical materials. The system-structural method was used during the study of normative legal acts of a universal, regional and national nature. Using the comparative legal method, norms of international law and national legislation of Ukraine in the field of transplantology were compared. The paper proves that the most important international legal standard dedicated to the fight against the illegal circulation of human anatomical materials is the Council of Europe Convention against Trafficking in Organs, which provides for criminal law prohibitions that must be implemented by the participating states in their national legislation. All conventional prohibitions are combined into four related groups and compared with criminal offenses provided for by the Criminal Code of Ukraine. Novels of the draft criminal law, which provide for responsibility for illegal transplantation, trafficking in human organs and other illegal circulation of human anatomical materials, were also studied. A comprehensive analysis of the legal regime in the field of transplantology gave grounds for the conclusion of the need to ratify the Council of Europe Convention against trafficking in human organs on the way to the European integration of Ukraine. The research also established that some conventional prohibitions in the field of transplantology are at the same time types of corruption offenses, which are provided for in the current Criminal Code. This indicates the further need for a detailed analysis of such norms, establishing their features, interrelationship and correlation with the relevant provisions of the legislation of Ukraine.

Transplantation of human anatomical materials is an important method of treatment aimed at restoring human health, so improving the criminal law regulation of combating illegal transplantation is certainly important. This article provides a comprehensive scientific and practical analysis of the formation, development and reform of legislation that provides transplantation of anatomical materials to humans. To do this, the author systematically studied the regulatory legislation in the field of transplantation and the changes that have taken place in it, identified all the changes made to Art. 143 of the Criminal Code of Ukraine during its validity, the impact of these changes on the practice of application of Art. 143 of the Criminal Code of Ukraine. The study of the legal support of transplantation was conducted through three main stages of transformation of legislation during the independence of Ukraine. This allowed us to draw the following conclusions: 1) the subject of the crimes under Art. 143 today is human anatomical materials. This means that, in addition to human organs or tissues, it covers anatomical formations, human cells and human fetal materials; 2) the systematic change of regulatory legislation in the field of transplantation complicates the establishment of the current procedure and conditions of transplantation of human anatomical materials, and, as a consequence, complicates the detection of signs of illegal transplantation; 3) the current corpus delicti provided in Part 1 of Art. 143 of the Criminal Code, is material, which requires the establishment, in addition to the act, socially dangerous consequences (significant harm to the victim) and the causal link between the act and the consequence; 4) the subjective side of the crime provided by part 1 of Art. 143 of the Criminal Code, from the moment of adoption of the Criminal Code of Ukraine until December 28, 2019, both intentional and negligent violation of the statutory procedure for transplantation of human anatomical materials was criminally punished, and from December 29, 2019, the act can only be intentional and the attitude to consequences only negligent; 5) since the adoption of the Criminal Code of Ukraine and until now, the legislator has twice increased the penalties for crimes under Art. 143 of the Criminal Code. In the final case, the penalty was increased for all sanctions under Art. 143 of the Criminal Code without exception.
