In this article, the author examines the problems of legal regulation of public procurement in a state of emergency and quarantine measures. The purpose of this article is to study the changes that have appeared in the legislation of the Republic of Kazakhstan in connection with the introduction of the state of emergency and quarantine in the country. The author provides a legal assessment and analyzes the new norms of Kazakhstani legislation regulating public relations in the field of organizing public procurement. The closure of state borders, the violation of the usual, accumulated over the years, economic ties led to disruptions in the economic activities of state bodies. With all the disadvantages that took place, the positive factor was that the demand for the goods of Kazakhstani producers on the market increased. The introduced new method of public procurement using framework agreements made it possible, in turn, to ensure the guaranteed sale of products of Kazakhstani commodity producers, and also made it possible to apply import substitution of frequently purchased goods. In this article, the author, on the basis of a study of the current practice in this area, demonstrates the features of legal regulation of the sphere of public procurement in completely social new conditions with the help of novelties in legislation, and also reveals the features of the operation of legal norms regulating the sphere of public procurement of goods, works and services in conditions of a state of emergency and quarantine measures. The adoption of special measures by the Government of the Republic of Kazakhstan made it possible to transfer financial and economic relations in the state to a new format – "customer-supplier". The measures taken by the government have now been extended until the end of 2020. These measures on the part of the Government of the Republic of Kazakhstan made it possible to introduce a sparing legal regime for regulating this area for representatives of medium and small businesses, in order to minimize the losses of the latter arising against the background of the introduction of a state of emergency and quarantine measures. Taking into account the analysis of judicial practice in the consideration of cases on public procurement, the author emphasizes that in conditions of quarantine measures in Kazakhstan, as a rule, there are violations of the same type, both on the part of customers and on the part of suppliers.
