Yeah ICC and CSA don't want this and will try to avoid such scenario, as of now CSA first option is to challenge The South African Sports Confederation and Olympic Committee (SASCOC) legally and see what happens, if things goes south then CSA is $%ked for sure
No idea about the political climate in the region and it sounds like things are getting worse in terms of quality of players produced and the cricket board is in a power struggle at the moment which it is not a good sign for the future of the sport, just like the Zimbabwe issue if things gets worse then we might see a partial ban for them and none of the teams will tour them, since there are T20 leagues around the world some of the players would not mind migrating if the political situation gets worse.
To be frank i was not to keep on these power struggles and the inside stuff behind the scene, where ever there is money people will try to grab their position is what is see from these situations.
