His progression from senior associate to partner reflects sustained client work on multi-jurisdictional deals and regulatory matters.

Competition Practice & Areas Of Expertise

As a Competition lawyer in Indonesia, Jonathan handles the full lifecycle of antitrust work: merger notifications and risk assessments, clearance strategy, KPPU investigations and defence, cartel and abuse-of-dominance matters, and compliance programme design. He is experienced in pre-transaction risk-scoping, post-transaction notification strategy, and interfacing with the Komisi Pengawas Persaingan Usaha (KPPU) on substantive and procedural reviews.

What Distinguishes His Competition Practice

Jonathan combines hands-on transactional experience with regulatory defence work, which allows him to advise clients on structuring deals to minimise KPPU exposure while preserving commercial value. His approach is data-driven and pragmatic: early market-definition analysis, clear assessment of jurisdictional thresholds, and coordinated stakeholder management during KPPU reviews. The combination of M&A transaction experience and specialist competition advisory work is particularly valuable for financial buyers, strategic acquirers, and domestic groups expanding by share or asset acquisition.

Competition Law In Indonesia: Landscape & Key Challenges

Indonesia’s competition regime is enforced by the Komisi Pengawas Persaingan Usaha (KPPU) and is principally governed by Law No. 5 of 1999 on the Prohibition of Monopolistic Practices and Unfair Business Competition, supported by various implementing regulations and KPPU rules. Recent regulatory updates — including KPPU Regulation No. 3 of 2023 (which clarified threshold calculations, local effect test, and introduced modernised electronic notification) and ongoing guidance on market-definition and digital platforms — make specialist advice essential for cross-border transactions and platform-driven markets.

Key practical challenges for businesses include Indonesia’s mandatory post‑merger notification regime in certain cases, evolving thresholds and local effect test, and the KPPU’s increased focus on digital markets and concentration risks. These developments mean parties must plan M&A risk and compliance work earlier in the transaction timetable and be prepared for data-driven market assessments.

Representative Workstreams & Client Types

Jonathan regularly advises acquirers and sellers on merger-reportability and notification strategy, conducts competition assessment, drafts and implements antitrust compliance programmes, and assists clients in KPPU process.
