The judicial system of commercial (arbitration) courts of Ukraine has undergone a difficult path of formation and approval. An active process of creating the system of arbitration courts in Ukraine began in 1991, with the adoption by the Verkhovna Rada of Ukraine of the Law of Ukraine ‘On the Arbitration Court’. This law defined the prerogatives of the arbitration court as one of the branches of the judiciary designed to administer justice in commercial relations. The main peculiarity of the arbitration court as a part of the judiciary was its specialization. Today we are the witnesses of the final stage of the reform of commercial courts and commercial justice as a whole within the adoption of the Law of Ukraine ‘On the Judiciary and Status of Judges’ in 2016.
