Authoritarian regimes regularly turn to the law to justify repression. This article examines whether invoking legal institutions has a persuasive effect on public perceptions of repression, and whether that effect is shaped by partisanship. The article uses the case of Cameroon's Special Criminal Tribunal, created in 2011 to prosecute high-profile corruption cases. A survey experiment was designed that describes the arrest and trial of a suspected corrupt oppositional minister and reminds a treatment group about the Special Criminal Tribunal. The results show that neither regime nor opposition partisans are swayed by legal justifications for repression. By contrast, nonpartisans respond negatively to autocratic legalism, particularly those with low levels of regime trust. The article clarifies when autocratic legalism might be used for public legitimation, suggests that partisanship is a useful lens for understanding public opinion in an autocracy, and elaborates upon the meaning of nonpartisanship in electoral authoritarian regimes.
