This chapter explores the legal order constructed and applied by the Russian Arbitrazh Courts. Based on empirical data, it scrutinises the way in which commercial courts in Russia operate, identifies the users of the courts, describes what those users expect to happen when they go to the courts, and discusses how the cases are processed. The chapter continues with a discussion of the balance between the different types of cases and analyses the consequences of the case structure for the operation of the Arbitrazh Court as an institution. It suggests insights into the way in which separate ‘rules of the game’ have emerged to reflect the types of cases and the different sets of actors involved. This distinction allows the authors to elaborate on the issue of corruption in the Arbitrazh Courts, describing its extent and the forms that it takes, and assessing the capacity of the institution as a whole to limit extra-legal activities. We conclude with a broad evaluation of the capacity of the Arbitrazh Court to contribute to the environment of legality within which business firms operate in Russia.
