This chapter looks at the Geneva (Switzerland) juvenile court in its first decade (1914–1925). The 1913 Act that established this court arose from ambiguous, apparently contradictory, ambitions: removing minors from the ambit of the criminal law, re-educating them, and repressing delinquency. The practice of the court shows—among other things—that the concern for re-education and other pragmatic factors were present in daily decisions. The introduction of ‘persistent misconduct’ as a basis for intervention that aimed to prevent future delinquency led to the imposition of important measures that can be viewed both from a welfare and from a repressive standpoint. The proactive role of some parents suggests that families were not mere subjects of repression but could take an active part in procedures.
