The House of Representatives on Monday officially adopted the revised 2010 state budget, despite opposition lawmakers walking out of proceedings to protest the appearance of Finance Minister Sri Mulyani.

Members of the opposition Indonesian Democratic Party Struggle (PDI-P) and People's Conscience Party (Hanura) factions left the meeting while it was still underway, causing proceedings to be adjourned temporarily.

When House Deputy Speaker Anis Matta of the government-aligned Prosperous Justice Party (PKS) was making the meeting's opening remarks, a number of House members interrupted him and asked why Sri Mulyani was present.

Before the walkout, a number of House members had proposed the meeting be adjourned temporarily to discuss matters related to Sri Mulyani's presence.

But Anis said the finance minister was attending the meeting at the invitation of the DPR and based on the decision of the House Consultative Body (Bamus). "The House invited Sri Mulyani on the basis of a Bamus decision," Anis Matta said.

House member from the PDI-P faction, Bambang Wuryanto, said the House's Budgetary Body had decided that the end result of the House's discussions on the revised 2010 state budget with the government was to be co-signed by the Coordinating Minister for Economic Affairs Hatta Rajasa (istead of by the finance minister-ed).

"This means there is a difference of views, and therefore it is better for the PDI-P faction to leave this plenary session," Bambang said before leaving the meeting.

After that, the other members of the PDI-P also left the meeting room, followed by members of Hanura. In response to the walkout, the speaker decided to adjourn the meeting to give House members an opportunity to hold inter-faction consultations or lobbying.
