Now that's changing. Following Mahathir Mohamad's surprise defeat of prime minister Najib Razak in the May 9 election, Malaysia's new government is acting quickly to address the 1MDB case.
Mahathir announced the task force's formation the same day that Malaysia's king, Sultan Muhammad V, presided over an oath-taking ceremony for 13 ministers in the prime minister's cabinet during an evening ceremony at the National Palace.
Najib has consistently denied any wrongdoing since the 1MDB scandal erupted in 2015, but he replaced an attorney-general and several MACC officers to shut down an initial investigation.
Najib, 64, has been summoned by the Malaysian Anti-Corruption Commission for questioning on Tuesday.
Abdul Razak Idris, a former senior officer with the anti-graft agency who last week lodged reports against Najib, praised the body for quickly hauling in Najib.
New MACC chief Mohd Shukri Abdull told reporters to expect a "special briefing" tomorrow. Police have raided his home and other properties linked to him, seizing hundreds of expensive designer handbags and luggage stuffed with cash, jewelry and other valuables. Mahathir, 92, was prime minister for 22 years until 2003 but emerged from retirement to join hands with former political foes amid anger over the 1MDB scandal.

The summons by the Malaysian Anti-Corruption Commission (MACC) comes as part of a widening investigation into Najib. It is up to those conducting the investigations.
At a party event Sunday in Pekan, Najib reiterated that he "didn't steal money from the people" and that the loss of his coalition which had led Malaysia since independence from Britain in 1957 was due to a vicious personal attack against him based on slander and lies.
These complaints alleged that more than US$4.5 billion was diverted from 1MDB and laundered through a web of shell companies and bank accounts located in the United States and elsewhere.
Bukit Aman CCID director, Datuk Seri Amar Singh Ishar Singh, said 284 boxes of luxury handbags were also confiscated from three more residential condominium units in the same area. "I am not a rogue", he said.
Mansor says the family will cooperate, but that authorities should not "be feeding social media trolls".
"The police urge the relevant parties to provide the details of the leaked photographs if any, to enable us to conduct an investigation to verify if in fact the photographs came from the police", Singh said, adding that Najib's family members and friends were present during the searches.
Mahathir has vowed to fully investigate the financial scandal.
