KUALA LUMPUR, May 6: DAP has backed a proposal by Kelantan Exco member Husam Musa for a citizens' suit against the Federal Government over  the signing away of two oil-rich offshore blocks in South China Sea to Brunei.

DAP's veteran leader and Ipoh Timur MP Lim Kit Siang said Husam should head a special committee by Pakatan Rakyat to prepare for such a suit.

"I will propose the establishment of such a special committee headed by Husam at the next meeting of the Pakatan Rakyat leadership council," Lim said in a statement today.

In proposing the citizens' civil suit yesterday, Husam, who is a member of PAS central committee, invited all Malaysians to join him in the suit.

"Everyone, including members of parliament, lawyers, NGOs and individual members of the public including from Sabah and Sarawak is invited to join me in filing this suit in the court," said Husam in a statement today.

He also said those interested may get in touch with him or his assistant at email gadailautmalaysia@gmail.com .

Husam also called on the establishment of a royal commission of inquiry to investigate the government's action in surrendering its jurisdiction to Brunei without going through parliamentary debate as required by the Constitution.

The controversy erupted following a report by The Edge Financial Daily on April 22 that the Malaysian government had given away two disputed oil-rich blocks off Sarawak's Limbang, incurring a loss of more than RM320 billion in oil earnings.
