The Supreme Court (SC) of the Russian Federation gave an expanded interpretation of the norm of the law on trade, which prohibits grocery chains with a share of more than 25% in the settlement to open new stores there. The precedent decision was made in the framework of the dispute between Pyaterochka and the Federal Antimonopoly Service. The Economic Collegium of the Armed Forces recognized that it is necessary to take into account not only the nominal retail space, but also how much profit they bring. Thus, the replacement of a non-working store with a working one can lead to an increase in the share in the local market, and it is the chain that must prove that this did not happen. Lawyers believe that the decision will make it more difficult for chains to manage stores and open new outlets. .
