Abstract: The object of this research is the public relations arising when the prosecutor is involved in court hearing of civil cases by intervening into a case for delivering an opinion in the appellate, cassation and supervisory bodies, as well as problematic aspects of the application of his powers to deliver an opinion in the aforementioned bodies. The subject of this research is the materials of prosecutorial law enforcement and judicial practice, norms of civil procedural legislation of the Russian Federation that regulation these public relations, as well as positions formulated on the matter. Despite the fact, that the scientific literature paid attention to the separate aspects of submission of prosecutorial decision, the questions of submission of prosecutorial decision in the retrial of civil cases did not receive due coverage. Such situation led to a contradictory approach towards the question on possibility of delivering an opinion by the prosecutor in retrial of civil cases in the theory and case law. Therefore, based on the conducted research, the author makes recommendation with regards to exercising prosecutorial powers in submission of decision in retrial of civil cases by the courts, as well as the changes in current legislation that would bring certainty into these legal relations and contribute to elimination of the emerged contradictions.
