To preserve nature, it is necessary to carefully monitor the state of the natural environment, normalize and prevent industrial emissions, and develop and implement waste-free and resource-saving technologies. Chemical safety is an important element of the national security of the Republic of Kazakhstan in “green economy” conditions. The main goals of safe management are prevention, reduction, minimization of toxic substances’ potentially harmful effects on public health and environment. Today, humanity has begun to realize that any economic branch first of all affects the environment. Therefore, the world community is considering various mechanisms for preserving the environment, and certainly, the idea of a green economy is one of them. A green economy is not just an opportunity, but a mandatory path of development for all countries which strive to ensure a secure future for their citizens. The present research aims to suggest recommendations concerning the legal issues of the transition to a green economy and to improve the regulatory framework of the Republic of Kazakhstan. In the course of the study, the authors propose theoretical and practical recommendations for improving the current state mechanism for the transition to a green economy.

By destroying the environment, any modern society destroys its own future. For the prosperity of future generations, the environment must be preserved. To preserve nature, careful monitoring of the state of the environment, rationing and prevention of industrial emissions, development and implementation of waste-free and resource-saving technologies are required. The use of natural resources by a person with complete ignorance of the laws of nature often leads to dire, irreparable consequences. At present, humankind has begun to realize that any sector of the economy primarily affects the environment. And therefore, the world community is considering various mechanisms for preserving the environment. And of course, the idea of a green economy is one of them. A green economy is not just an opportunity, but an indispensable development path for all countries and states that aspire to ensure a reliable future for their citizens. The purpose of the study is to investigate the need and importance of the country's transition to a green economy; to research the experience of foreign countries in the transition to a green economy; to consider the ‘green economy’ as a legal phenomenon, as well as to investigate the legal issues of the transition and improvement of the regulatory framework of Kazakhstan for the transition to the green economy. The research methodology consists of materialistic dialectics, formal logical, historical law, system-analytical, comparative law and specific sociological research methods. Theoretical and practical recommendations for improving the current state mechanism for the transition to a green economy were proposed in the course of the study.

A number of new economic, political and social conditions, among which are the updated legal framework for ensuring a market economy and establishing private ownership of land, explain the significant changes in the concept and content of land acquisition in Kazakhstan. The public and the private in the property rights are undoubtedly mutually conditioned, these concepts have not only many intersections, but also clashes that reach their climax in the situation of compulsory turning the private property in the public. This article considers the main theoretical aspects of land seizure under the legislation of foreign countries. Determining the general aim of the legislation, the authors made objective scientific conclusions for improving the state-legal regulation of this area.

In the process of reforming the criminal procedure legislation, the institution of the prosecutor’s office has become one of its important aspects. The judiciary, being one of the independent and autonomous branches of power in criminal proceedings, which is a system of protecting the rights and freedoms of citizens, is by far the most effective structure for protecting human rights. The article reveals the essence of judicial control and prosecutorial supervision, identifies a number of problems in the form of potential threats to ensure the rights and legitimate interests of a suspect (accused) in this form of preliminary investigation. As a result of the study, the following was stated. The current provisions of the CIS constitutions regulating the sphere of human rights and freedoms have made it possible to single out separate independent areas in the activities of the prosecutor’s office. Based on the practical problems that arise in the conditions of the new Criminal Procedure Code in the CIS countries, the authors consider it reasonable that the current oversight functions assigned to the prosecution authorities in ensuring the rights and freedoms of a suspect and an accused during the investigation, necessitate further special studies with the aim of development of evidence-based proposals for their resolution.
