A court last month acquitted the three companies – Wilmar Group, Musim Mas Group, and North Sumatra-based Permata Hijau Group – of charges of misconduct in obtaining export permits in 2022.

The three judges who made the ruling were arrested yesterday night, a spokesman for the Attorney General’s office Harli Siregar told Reuters in a text message today.

On Saturday, prosecutors arrested Arif Nuryanta, chief judge of South Jakarta district court.

“He was allegedly paid Rp60 billion (US$3.57 million) to arrange for a favourable verdict by two lawyers for the companies,” Siregar said in a statement, adding that US$1.07 million was then allegedly paid to the three other judges.

“The bribe was given so that the judges would rule that it’s not a crime,” Siregar said, adding that a court clerk and two lawyers had also been arrested.

Reuters could not immediately reach the three judges or their lawyers for comment.

Siregar said the Attorney General’s office had filed an appeal against the court’s March acquittal of the companies.

Wilmar Group, Musim Mas Group and Permata Hijau Group did not immediately respond to a request for comments.

Nuryanta was the deputy chief of the court when the verdict was announced. He did not hear the case directly.

Indonesia, which accounts for about 60% of global palm oil supply, imposed severe export measures in 2022, including a three-week ban on shipments, in an attempt to rein in soaring prices of local cooking oil.

When the corruption charges were first brought against the companies, prosecutors were seeking fines and payments of up to Rp11 trillion.
