Indonesia’s highest court has declined to enforce Singapore arbitral awards against a local company on the grounds that doing so would “interfere with the judicial process in Indonesia,” according to the Malaysian company seeking enforcement.

Astro Malaysia, a Kuala Lumpur-based conglomerate led by billionaire Ananda Krishnan, has been involved in a dispute since 2008 with the Lippo Group, an Indonesian conglomerate controlled by the Riady family, over a failed satellite television joint venture in Indonesia. In a series of decisions in 2010, a three-member panel of the Singapore International Arbitration Centre awarded Astro around $300 million.
