The court judgment plays an important role in the mechanism of judicial protection of the rights and legitimate interests of citizens, organizations and the state. Being the result of judicial proceedings, it governs the further development of public relations. Not any, but only an effective court judgment ensures the real achievement of both private and public goals of civil litigation with minimal costs.

Using the advanced methods of law and economics and sociology analysis, the main aspects of judicial acts issued by court because of civil case resolution are analyzed. Doctrinal issues of the judgment’s efficiency in all its manifestations have become the basis for practical-oriented conclusions, which implementation will increase the effectiveness and efficiency of civil justice system. The author also notes that when the legal goal has been achieved by the court, legality has been ensured, but an undesirable social effect has occurred, which was caused by law enforcement activities, it is necessary to pay attention to the complex inefficiency of the proceedings, and not to the negative effectiveness of the judicial act.
