Which criteria do Russians use to evaluate the fairness of their judges, and how does perceived fairness of actual trials influence general beliefs about Russian courts? Lay assessors at courts in South Russia were asked about their experience serving on mixed courts. The justice of the verdicts rendered and the fairness of judges partly explain the respondents’ view of national courts. According to the results, the respondents are also using similar criteria for fairness as Americans or Germans. The social and psychological group effects in a Russian court of lay assessors exhibit a striking similarity to other Western tribunals.
