But in an interview on Talk Radio 702, CSA President Mtutuzeli Nyoka dismissed suggestions of possible big IPL bonus payments to CSA officials being the reason for the refusal to share the contract.
After a meeting of affiliates a fortnight ago, CSA announced that GCB should apologise to the national authority for the game, as well as the BCCI and IPL for allegedly defamatory remarks made in the documents. Until such an apology, no international games would be permitted at the Wanderers.
Remaining resolute not to apologise until it had seen the contract between the IPL and CSA, GCB has already lost three matches in the coming England tour to other venues in the country as CSA carried out its threat.
CSA also announced Thursday that South Africa will not play at the Wanderers during the International Cricket Council's Champions Trophy in September.
The ICC earlier said scheduling decisions vested with the national authority of the host country, although the English Cricket Board had earlier expressed concern on behalf of fans about travel and accommodation arrangements that had already been made for the previously announced games at Wanderers.
South African fans were also irate at the possibility of never seeing any international games at Wanderers again.
