Abstract
Psychological justice research has mainly focused on the citizen, not judicial officers, and found that they evaluate and react to judicial events from the viewpoint of not only self-interests but also justice and fairness. Based on the empirical methodology, psychologists have addressed three basic issues of justice: By what cognitive processes do people shape a justice perception, what kinds of behavioral or psychological responses does the perception of justice or injustice motivate, and why are people concerned with justice, that is, what is the source of justice concerns? Whereas the citizen is regulated by the law and enjoys its service, they also support or criticize the law based on their social norms. Since justice is a part of the social norm, it can be argued that justice endorses and underlies the law. On the other hand, the social norm is formed through people’s social experiences, including culture and the developmental environment, which are determined by the law events, suggesting a cyclic relationship of justice and the law in which both influence each other. From this point of view, comments to presentations by three symposiasts were made.
