Indonesia's Supreme Court upholds 10-year sentence for ex-Taspen CEO in corruption case

Indonesia's Supreme Court has denied the appeal of former state pension fund (Taspen) CEO Antonius Nicholas Stephanus Kosasih, upholding his conviction and 10-year prison sentence for corruption. The ruling came after Kosasih challenged a lower court's decision that found him guilty in a case involving fictitious investments that allegedly caused Rp 1 trillion (approximately $61 million USD) in state losses.

The Supreme Court's decision, dated May 21, 2026, was announced on June 3. The panel of judges, led by Jupriyadi, dismissed Kosasih's cassation plea. This follows an earlier verdict by the Jakarta Corruption Court on October 6, 2025, which found Kosasih guilty of violating corruption laws.

In the initial ruling, Kosasih was sentenced to 10 years in prison and fined Rp 500 million. He was also ordered to pay state restitution amounting to Rp 29.15 billion, along with various foreign currencies. The court stipulated that failure to pay the restitution within one month of the verdict becoming final would result in an additional three years of imprisonment.

The DKI Jakarta High Court had previously upheld the Jakarta Corruption Court's decision but modified the additional prison term for non-payment of restitution from three to five years. The Supreme Court's rejection of his final appeal solidifies the conviction and sentence against the former Taspen executive.
