Dewan Rakyat speaker Pandikar Amin Mulia says it is sub judice to discuss the United States Department of Justice (DOJ) suit on 1MDB assets, because the Hansard could then be cited by the DOJ in the US hearing.

"Even if no one from Malaysia is called to testify in the trial in America, they can quote what is being said in the Malaysian Parliament in order to influence the trial in the America.

"This is why I did not allow the debate, because every argument made here can be used in the American trial, even if it is in a foreign land.

"What the minister said here can be quoted in the American trial. In my opinion, this can influence the trial," he said.

Pandikar Amin said this at a press conference at the Parliament lobby today.

Meanwhile, Pandikar also cited a Standing Order 23 (1)(g), 36 (2), 21 (1)(g), 36 (2), 21 (1)(a) and 23 (1)(g) to support his decision.

On Monday, Pandikar had ruled that the question need not be answered because of the DOJ's civil forfeiture suit in California that was filed in July.

The DOJ is attempting to seize about USD1 billion in assets through the FBI's Kleptocracy Asset Recovery Initiative in relations to 1MDB's assets.

The FBI had claimed that Malaysians were defrauded on an "enormous scale" in a scheme involving the misuse of 1MDB monies.

Among other contentious matters, the DOJ's filing alleged that 1MDB monies eventually made it into the bank accounts of one "Malaysian Official 1".

'Let us discuss ruling'

Prime Minister Najib Abdul Razak, who is the head of 1MDB's advisory board and a key decision maker in the company, said that the DOJ suit does not involve him.

In a related development, Puchong MP Gobind Singh Deo today filed a motion to appeal against Pandikar's ruling.

"In appears to me the rule does not apply to proceedings overseas, regardless of whether he has appraised himself of the facts of the case.

"The MP who proposes the question must be heard. If objections are raised from the other side based on sub judice, then a ruling can be made.

"(The speaker) can't place a blanket rule," said Gobind told reporters at the Parliament lobby today.

Gobind hope that his motion to seek the review be debated to allow MPs to discuss the speaker's ruling in order to establish a guideline.
