Chief amongst these is the immediate recall of Cde Jacob Zuma as the President of the South Africa.
Zuma has been South Africa's most controversial president since the end of white minority rule in 1994, enwrapped in scandal during a tumultuous nine years in power.
Ruling party leaders are uncomfortable with the idea of backing an opposition-sponsored vote against Zuma in parliament, fueling speculation that the ANC will make an internal decision to remove him in the same way that President Thabo Mbeki was ousted in 2008 with less than a year left in his second term.
Mr Zuma has repeatedly denied corruption allegations.
"Cyril Ramaphosa has postponed the special NEC (national executive committee) meeting", the ANC said in a statement.
"We are not going to discuss the outcome with you because we don't know what the outcome will be, " she said.

The Fed has prohibited the bank from becoming any larger than its 2017 end of year total assets until there have been sufficient improvements made.
The allegations reported in the media that President Jacob Zuma wishes to fire Deputy President Cyril Ramaphosa and replace him with Dr Nkosazana Dlamini Zuma are preposterous and outrageous.
He waved to reporters after meeting Ramaphosa at the president's office in Cape Town, where the president also chaired routine meetings, his spokesman said.
Some ruling party members have pushed for ANC leaders to demand that Zuma resign.
BLF members had meant to protest outside the ANC headquarters and hand over a memorandum demanding that beleaguered President Jacob Zuma serve out his term, which ends next year. Other options for his removal include impeachment proceedings in parliament or a vote on an opposition-sponsored motion of no confidence that is scheduled for February 22. This was contrary to reports that the party's leadership was working on a plan for Zuma to leave peacefully.
But an address by Zuma would leave some ANC lawmakers in a hard situation - whether to visibly support him, adopt a critical pose, remain neutral or boycott the address.
"This we have done and we are satisfied that insisting on Sona on Thursday will not serve any objective", said Modise explaining why they changed their stance from last Thursday's position where they were adamant that there will be no postponement.
The NEC will also discuss preparations for the annual state of the nation address on Thursday evening, the speech at the opening of parliament during which the president outlines the government's legislative agenda for the year.
