28 December 1989
On 28 December 1989, a document officially banning nine members of the African National Congress (ANC) was circulated at Dakawa in Tanzania. The nine members were from different ANC communities in Dakawa. The decision to ban these members followed the announcement made during meetings held by Chris Hani and Stanley Mabizela at Mazimbu and Dakawa on 24 December 1989. During the meetings, Mabizela revealed the ANC’s National Executive Committee’s (NEC) decision on the three groups of people detained by the organisation. These three groups were: (a) self-confessed enemy agents who had been imprisoned and released unconditionally. This group was allowed to take part in and occupy positions in the ANC structures; (b) enemy agents who had been imprisoned and released conditionally. This group was not allowed to take office in the ANC structures; and (c) a group of 1984 mutineers who had been imprisoned by the ANC and forbidden from taking office in the organisation’s structures. The angry Hani had to shout during the meeting at Dakawa stressing that “this decision is not to be challenged; it is an order from the NEC.”
