Busisiwe Mkhwebane's Bankorp-CIEX report, in which ABSA was ordered to pay R1,125-billion, was set aside by the Pretoria High Court on Friday.
Public Protector Busisiwe Mkhwebane's report is "absolutely disgraceful," says opposition leader Mmusi Maimane.
MPs want Mkhwebane to explain remarks about aspects of her investigation.
The SACC would also write to the chair of the commission to 'solicit his understanding of the status of the Public Protector's recommendations on the terms of reference'.
But former Public Protector Thuli Madonsela says the inquiry must keep to the scope of her investigation.
It emerged that the Eastern Cape government had no plans in place for the funeral, and scrambled to plan one when Mandela died in 2013.
"It appears as if the Reserve Bank is trying to have Mkhwebane removed from her office."
Corruption, maladministration and greed overshadowed the former statesman's funeral.
A report in May 2016 revealed that R22m was used for T-shirts, food and transport.
The Public Protector wants to have her cake and eat it. Not possible, says Absa.
