Procedural justice is concerned with the perceived fairness of authorities. A person’s perception of just processes derives from being given voice and respect, as well as being treated in a manner that is neutral and trustworthy. Research finds that procedural justice increases the perceived legitimacy of authority and subsequent compliance with the law. Although the causal link and potential other factors predicting these outcomes can be debated, there is a large amount of evidence connecting procedural justice to positive interactions between citizens and authority figures. Beyond interactions with and relationship to authority, emerging research further suggests that procedural justice may foster motivation for citizens to engage with and actively support their communities.
