T The development of information technology has brought significant changes in digital-based banking transaction and service systems. however, this progress has also given rise to various forms of cybercrime, one of which is the breach of banking security systems. legal problems arise when perpetrators claim their actions were carried out in the context of implementing statutory provisions, thus giving rise to debate regarding the application of article 50 of the criminal code as a justification. this study aims to analyze the appropriateness of imposing criminal sanctions on perpetrators of breaches of banking security systems and examine the judge\\\'s legal considerations in decision number 48/pid.sus/2023/pn.nga. the problem formulation focuses on the application of article 50 of the criminal code in cybercrime cases and the basis for the judge\\\'s considerations in issuing criminal sentences. the research method used is a normative legal research method with a statutory approach, a conceptual approach, and a case approach, using primary, secondary, and tertiary legal materials. the results of the study indicate that the application of the criminal sanctions imposed is relatively light. the judge\\\'s considerations are considered to reflect the principles of legality, legal certainty, and substantive justice.
