Opposition leader Dr Wan Azizah Wan Ismail's no confidence motion against attorney-general Mohamed Apandi Ali is a political move, constitutional expert Abdul Aziz Bari said today.

"The motion only has political significance because he (Apandi) is technically appointed by the prime minister," Aziz told Malaysiakini when met at the DAP headquarters in Kuala Lumpur today.

Under the law, Aziz said the motion will have little impact on Apandi's position.

"The Malaysian Bar's decision to file a judicial review is also a similar move.

"It (the motion and judicial review) will have little impact but can give some weight and put pressure on the fact that position of AG is becoming more and more untenable," he said.

Wan Azizah had earlier today said Dewan Rakyat speaker Pandikar Amin Mulia had rejected the no-confidence motion against Apandi.

Wan Azizah, who submitted the motion on Feb 25, told reporters in Parliament that the motion was deemed unconstitutional.

The Malaysian Bar, meanwhile, has filed for a judicial review on Apandi's decision not to press charges against Prime Minister Najib Abdul Razak.

Malaysian Bar president Steven Thiru in a statement yesterday said the Bar is of the view that the discretionary prosecutorial powers conferred on the attorney-general by Article 145(3) of the Federal Constitution are not absolute or unfettered, and can be challenged in a judicial review action.

In its application, the Bar is seeking orders from the High Court to set aside Apandi's Jan 26 decision exonerating Najib and his instructions to the Malaysian Anti-Corruption Commission (MACC) to close its investigations.

It also wants the court to bar the attorney-general from making any further decisions on the matter, and allow the solicitor-general to make those decisions instead, including on whether or not to prosecute Najib.
