Finance minister-designate Lim Guan Eng has declined to speculate on the future of his ongoing graft case, saying it is sub judice.

Lim said many cases would have to be reviewed but it is uncertain if his case, which is linked to the purchase of his bungalow on Jalan Pinhorn, Penang, would also go through a similar process.

The trial is supposed to resume on May 21 at the Penang High Court.

"As (prime minister) Dr Mahathir Mohamad said, the MACC chief (Dzulkifli Ahmad) has to be replaced for obvious reasons.

"We need to review all the cases thoroughly to see whether there were political motives involved against opposition politicians," Lim said.

"The victory of Pakatan Harapan on May 9 is akin to the judgement of the people on the veracity and reliability of these cases, not just those against me, but against others as well," he added.

Former second finance minister Johari Abdul Ghani had previously said he believes that Lim is innocent until proven guilty.

As DAP secretary-general, Lim was also asked about PKR vice-president Rafizi Ramli's complaint that the announcement of his post – along with those of Amanah's Mohamad Sabu as defence minister and Bersatu's Muhyiddin Yassin as home minister – did not get the blessings of PKR.

To this, Lim said, "Next question, please," drawing laughter from those present at a press conference at his Komtar office.

The outgoing two-term chief minister was also asked if would be dropping his defamation suits against state BN chief Teng Chang Yeow and state Gerakan acting youth chief Jason Loo.

In response, he asked the reporter cheekily, "Where are you from?"

Lim was also asked about BN assemblypersons defecting to Pakatan Harapan, after an lawmaker from his own party, Bukit Gelugor MP Ramkarpal Singh, and several NGOs voiced their disapproval over such “party-hopping.”

He was reminded that Penang had also passed an anti-party-hopping law after the 2013 polls.

Lim responded by urging for more time to access the situation, saying he had neither read Ramkarpal's comments, nor had information on the situation in the various states.

"Let me look at the situation first. I want to be hands-on in my ministry and have been devoting my time to that.

"I do not really have the time to look or scan all the reports so can you please give me an opportunity to look at these first before I comment?" he asked.
