Using detailed vignettes and scale measures, concepts of laws regulating domain‐specific issues and engagement in delinquency were assessed among 340 9th through 12th graders (Mage = 16.64, SD = 1.37). Adolescents distinguished between laws that regulate moral, drug‐related prudential, conventional, personal, and multifaceted issues in their criterion judgments and justifications. Youths’ ratings of the importance of laws, obligation to obey laws, and deserved punishment for breaking different laws also followed domain‐consistent patterns. Adolescents’ engagement in moral, drug‐related prudential, and multifaceted forms of delinquency was associated with less supportive judgments about laws within the same domain. Findings contribute to civic development research by demonstrating domain specificity in adolescents’ beliefs about laws and suggest that these beliefs are linked with engagement in similar types of delinquency.
