T The criminal offense of *pengeroyokan* (group assault) is a form of communal violence that remains prevalent in national crime statistics, characterized by a wide disparity in sentencing—ranging from four months to twelve years of imprisonment. this study aims to analyze the accuracy of the legal classification regarding the injuries sustained by the victim based on the elements of the offense, as well as the appropriateness of applying article 56 of the criminal code (*kuhp*) to classify the defendant\\\'s role as an accomplice (*pembantu*) in court decision number 508/pid.b/2023/pn.smg. employing a normative-juridical method with a descriptive-analytical approach, the study utilizes secondary data—comprising primary, secondary, and tertiary legal sources—and conducts a qualitative analysis leading to deductive conclusions. the findings indicate that classifying the victim\\\'s injuries as \\\"minor injuries\\\" under article 170 paragraph (2) point 1 of the criminal code was legally sound, as the injuries did not meet the criteria for \\\"serious injuries\\\" defined in article 90 of the criminal code (i.e., there was no life-threatening danger, permanent disability, or continuous inability to work). furthermore, the application of article 56 of the criminal code to classify the defendant as an accomplice aligns with the concept of criminal participation (*penyertaan*) in criminal law doctrine; the defendant did not personally commit the core act of violence against the victim but instead provided assistance by obstructing those attempting to aid the victim. the study concludes that the judicial decision was legally sound and proportionate, notwithstanding the scope for academic debate regarding the distinction between aiding (*pembantuan*) and co-participation (*turut serta*) in the offense of group assault.
