Johannesburg to have four election sub-structures JOHANNESBURG August 4 Sapa The Electoral Court decided on Friday to adopt a four sub-structure model for Johannesburg's inner boundaries. The decision means local government elections can take place in the city on November 1 as scheduled. Appeal Court Judge John Smallberger said the model - favoured by the African National Congress - was chosen because it seemed better balanced than the three or seven sub-structure models proposed by other parties. The court on Thursday convened urgently to consider on the dispute. Its decision is final.
