KUALA LUMPUR (Nov 13): The Public Accounts Committee (PAC) will, on the first week of December this year, kick-off its investigation into allegations that the 2016 Auditor-General's (A-G's) report on 1Malaysia Development Bhd (1MDB) had been tampered with.

As for other proceedings relating to allegations of wrongdoing at the fund, those will be postponed until the criminal charges in relation to the matter that have been brought to court are disposed of.

"The PAC has made the decision to set three days for the proceedings [on the audit report] on Dec 4, 5, and 6," PAC deputy chairman Wong Kah Woh told reporters at the parliament lobby today.

Witnesses the PAC will be calling during the proceedings include former A-G Tan Sri Ambrin Buang and current A-G Tan Sri Madinah Mohamad, said Wong.

"As to the core issue of the 1MDB scandal, we will take it when the time comes, depending on the progress of the case prosecution by the Attorney-General's Chambers," he said.

PAC chairman Datuk Seri Dr Ronald Kiandee told reporters the PAC decided to delay its reinvestigation into 1MDB as Attorney-General Tommy Thomas has advised that reopening the case now may be prejudicial due to the 1MDB-linked criminal charges that have been brought to court. Hence, the PAC has postponed its proceedings on the matter indefinitely, while the law takes its course.

In March 2015, the previous government ordered the National Audit Department to audit 1MDB accounts, and the resultant audit report was submitted to PAC two months later. But in March 2016, it was revealed the report had been classified as state secret under the Official Secrets Act, before the PAC tabled its own 1MDB report in Parliament. The report was declassified in May this year.

Last month, Wong claimed that the A-G's report on 1MDB had been tampered with on the instruction of certain individuals, as he slammed the previous PAC for failing to re-open investigations into the investment fund despite the civil suits filed by the United States' Department of Justice alleging that money had been siphoned from it.

Ambrin has previously denied that his report was tampered with.
