The present research explored the role of leader morality in the interaction effect of procedural justice and outcome favorability, and attempted to connect justice and morality construct in a new direction. Two studies in different settings and using different designs (a scenario experiment and a survey) yielded convergent results. When leader morality was high, the interaction effect of procedural justice and outcome favorability was significant, and fair procedures mitigated the negative effect of low outcome favorability. When leader morality was low, however, the interaction between procedural justice and outcome favorability was absent.
