Explaining Police Procedural Justice in a Democracy: An Expanded Internal-External Model

Since procedural justice was proposed, this vein of research has gained much popularity in scholarship, empirical supports, and theoretical advancement. Yet, research on the procedural fairness within police organizations, particularly on the underlying and mediating mechanisms between internal and external procedural justice, remains understudied. Relying on survey data collected from Taiwanese police officers, this study expands the current literature by testing the direct relationships between supervisor, organizational, and social supports and external procedural justice and their indirect connections through supervisor trustworthiness and self-legitimacy. Supervisor and social supports were found to directly boost officers’ commitment to external procedural justice. Perceived organizational support promotes external procedural justice through cultivating officer self-legitimacy. This study concludes by discussing cross-border research and pragmatic implications for police training and management.
