The Influence of Police Treatment and Decision-making on Perceptions of Procedural Justice: A Field Study

Objectives: This study examines whether police behavior that signals higher quality of treatment or decision-making leads to higher perceived procedural justice. Methods: Analyses are based on data collected during police traffic controls of moped drivers in two Dutch cities over a period of six months. Police behavior was measured through systematic social observation (SSO), and data on perceived procedural justice were collected through face-to-face interviews immediately after the encounters. Linear regression analysis with bootstrap estimates was used (n = 218), with an overall perceived procedural justice scale as the dependent variable in all regressions. Independent variables included an overall observed procedural justice index and four separate scales of police treatment and decision-making. Results: We find no evidence that police behavior that signals fairer treatment or decision-making leads to higher perceived procedural justice. Conclusions: Our findings add to the currently very limited empirical evidence on an important question, and raise questions about a central idea, that more procedurally just treatment and decision making by authorities leads to an increase in perceived procedural justice and enhanced compliance. The first of these requires more research.
