  • Successful defence of PT Coca-Cola Bottling Indonesia (CCBI) in a criminal investigation process by the West Java Provincial Prosecutor's Office for the allegation of crime which causes losses to the state. A decree to halt the investigation of the case (surat perintah penghentian penyidikan) was later issued by the Prosecution Service on account of the fact that there is no criminal intention.

In fact, the extraction license was in process of renewal at the time when the charges were laid.
  • Successful representation of the winners of Indonesia's 2014 Presidential Election, President Joko Widodo and Vice President Jusuf Kalla, against an action by opposition parties in the Central Jakarta District Court challenging the results of the Presidential Election on the ground that the General Elections Commission had prematurely opened ballot boxes in many constituencies. We argued that the District Court had no jurisdiction to hear the case, as under the electoral legislation all electoral disputes should be heard by the Constitutional Court. The judicial panel accepted our arguments and threw out the case. The plaintiffs did not exercise their right to appeal to the Constitutional Court.
  • Successful defence of Garmin USA Inc, a US-based air navigation technology company, as Third Defendant in a civil action filed by the heirs of 4 (four) deceased passengers of the Mimika Air crash of 17 April 2009. The plaintiffs each claimed USD 150,000 in damages. The District Court found in Garmin's favor as the action had not been brought within 2 years and was thus statute-barred under the Aviation Act. The trial court's decision was upheld on appeal by the Jakarta High Court.
