THE appeal of former president PW Botha (83) against his conviction for ignoring a Truth and Reconciliation Commission subpoena was postponed to be heard in the Cape High Court on Friday. The postponement is to allow for outstanding matters. Botha was convicted last August for ignoring a summons to testify to the commission, thereby contravening the Promotion of National Unity and Reconciliation Act. If his appeal fails, he is liable for a R10000 fine or a year in jail.
