The article is devoted to commenting on the decision of the Supreme Court of the Russian Federation, which addresses a number of significant problems of arbitration practice.

The approaches of the Supreme Court to the arbitration decision on the basis of re-evaluation of the circumstances of the case are also contradictory.
