<![CDATA[Corruption in natural-resource governance presents distinctive challenges because criminal liability may arise from complex commercial arrangements involving public resources, state revenues, and private actors. The tin trading case examined in Supreme Court Decision No. 5009 K/Pid.Sus/2025 provides an important context for analysing how judicial reasoning determines individual criminal responsibility in large-scale economic crimes. This study aims to examine the ratio decidendi employed by the Supreme Court in assessing the defendant's criminal liability and the relationship between commercial conduct, state financial losses, and the elements of corruption. A normative juridical method is employed through statutory, conceptual, and case approaches. The analysis focuses on the construction of unlawful conduct, causation between the defendant's conduct and state losses, the evidentiary basis for attribution of responsibility, and the judicial assessment of punishment. The study argues that corruption cases involving natural resources require courts to distinguish carefully between legitimate business activities and conduct that constitutes criminal participation in the misuse of public resources. The decision is particularly relevant because the Supreme Court rejected the cassation applications, thereby maintaining the legal consequences of the lower courts' adjudication. The research demonstrates that judicial reasoning in resource-related corruption cases must integrate criminal-law principles with the regulatory structure governing natural-resource commerce. The study contributes to discussions on corporate-related corruption, state-loss doctrine, and judicial accountability in the governance of strategic natural resources.]]>
