Administrative justice receives varying emphasis in different jurisdictions. This article explores empirical legal studies, which fall on either side of the decision making-and-review dividing line. It then seeks to link research on the impact of dispute resolution and on-going administrative practices. The article also highlights limitations in existing impact research, focusing on the tendency to examine single dispute resolution mechanisms in isolation from others. Furthermore it suggests some future directions for empirical administrative justice research. It also explores the potential of legal consciousness research for empirical administrative justice scholarship, and suggests new territories for administrative justice researchers: criminal justice processes and administrative activities of private agencies. It concludes by presenting an argument that a mapping of administrative justice institutions, both historically and cross-jurisdictionally, can reveal much about how relationships between citizens and administrative agencies may shift across time and space.
