Effectiveness of Law No. 5 of 1999 in Handling Cross-Border Business Competition

This paper examines the issues of business competition in an extraterritorial context and its implications for the authority of the Indonesian Business Competition Supervisory Commission (KPPU). The research focuses on the extent to which the KPPU can enforce its duties beyond the borders of Indonesia, particularly concerning the effective application of Law No. 5 of 1999. Analysis of KPPU's decisions in extraterritorial cases, especially those involving share acquisitions, provides insights into the approaches and solutions adopted. The study aims to foster discussion on the role of KPPU in addressing extraterritorial challenges, along with the application of international cooperation and principles of international law in enforcing competition law. The research findings are expected to offer recommendations to enhance the effectiveness of KPPU's enforcement of competition law in a global context.
