Irawady Joenoes, a member of the powerful Judicial Commission, is the latest official jailed as part of a government campaign to tackle endemic corruption.

'The action of the defendant is in contradiction with his obligations as a member of the Judicial Commission,' said Mr Masrurdin Chaniago, a judge at the special anti-corruption court.

Joenoes was found guilty of receiving the cash from a businessman as a bribe linked to a land deal for the commission's new office.

Joenoes was the coordinator of a division in the commission tasked with monitoring judges' behaviour and integrity.

The judge also ordered him to a pay a fine of 400 million rupiah or serve an additional six months in jail.

Joenoes denied any wrongdoing to reporters and said he would appeal the verdict.

Experts consistently rate Indonesia as among the world's most corrupt nations, with legal uncertainty and perceived graft in the judicial system among some of the most frequent complaints of foreign investors operating in Indonesia.

President Susilo Bambang Yudhoyono won Indonesia's first direct presidential vote in October 2004 on a pledge to end corruption.

Since Dr Yudhoyono's anti-graft campaign started, officials ranging from governors and former ministers have been jailed on corruption charges. But some critics argue the anti-graft campaign has tailed to take on some powerful vested interests. -- REUTERS
