Nyoka has called for an inquiry into IPL bonuses paid to CSA Chief Executive Gerald Majola and other staffer.
Nyoka was fired by CSA but reinstated as President after he took the matter to the high court.
CSA initially converted Nyoka's external inquiry call to an internal one which cleared Majola after rapping him over the knuckles for not advising the CSA Board of the IPL bonuses.
After Nyoka's return, he initiated an external inquiry through auditors KPMG. At a meeting not attended by Nyoka, the Board considered advice on the KPMG report from advocate Azhar Bham and again cleared Majola after a "serious reprimand."
CSA then declared that it considered the matter closed.
CSA however has consistently refused to make public the full KPMG report, which reportedly put fingers at Majola of being in contravention of the Companies Act, according to leaked reports.
Nyoka has also been denied access to the report or Bham's advice.
Nyoka has acknowledged receiving notice of the 15 October special general meeting, called by the Members' Forum of CSA.
The Members' Forum is the supreme authority of CSA, consisting of the 11 presidents of the affiliates of Board.
The Member's Forum request for the meeting cites several reasons for the no confidence motion.
These include that Nyoka "brought the organsiation into disrepute by disregarding majority decisions of the Board" and that his actions "in the past year have brought serious damage to the reputation of CSA."
The allegations further state, "(Nyoka) has treated the Board in a contemptuous manner and has continued with his vilification of the board and its employees in the media."
Nyoka appears to be fighting a lone battle to clear up the controversy around the IPL bonuses, as other Board members who had flagged it at the time as irregular before resigning are now remaining very silent on the matter.
The CSA crisis previously prompted the attention of Sports Minister Fikile Mbalula, who is reported to be seriously concerned about the impact of the spat at board level on cricket in the country.
