During the past decade the study of the psychology of procedural justice has become well established within the field of justice. It has been widely found that people are as concerned with the fairness of the way decisions are made as they are with the fairness of those decisions (i.e., distributive justice). This paper identifies the questions which have dominated research on procedural justice during the past decade, discusses the conclusions which have been reached about those questions, and suggests important areas for future exploration by procedural justice researchers.
