Indonesia’s anti-monopoly agency is evaluating Temasek Holdings Pte’s assets in the country and said the government has the right to seize them if a court-imposed fine isn’t paid.

The Singapore state-owned investment company lost its final appeal in the Supreme Court on May 24 for violating antitrust laws, the Indonesian court said on its website at the time. A fine of 150 billion rupiah ($22.4 million), which includes 15 billion rupiah for each of 10 Temasek-linked companies involved in the case, was set, the anti-monopoly agency said.

“We’re now inventorying Temasek’s assets and expect to complete that in 2011, and they will be seized if the fine isn’t paid,” Tresna Soemardi, agency’s chairman, said in a phone interview today.

The Indonesian competition regulator KPPU has said Temasek breached antitrust laws by using indirect stakes in PT Telekomunikasi Selular, known as Telkomsel, and PT Indosat, the country’s top two mobile-phone service providers, to fix prices.

“Temasek has not received official notification from the Supreme Court,” Goh Yong Siang, Temasek’s senior managing director of strategic relations, said in an e-mailed response to queries.
