The Gauteng Department of Public Transport, Roads and Works invited tenders for a major road construction project, specifying that only contractors with a CIDB classification of 8CE PE or 9CE (for contracts exceeding R100 million) could tender. King Civil Engineering Contractors (Pty) Ltd, in a joint venture, did not initially qualify under the advertised criteria. At a compulsory site meeting, departmental officials incorrectly informed tenderers that contractors with a lower classification could also tender, and an addendum to the tender documents reflected this. King tendered, scored the highest points, and was recommended during technical evaluation. At final adjudication, however, the Departmental Acquisition Council disqualified King’s tender on grounds of unfair competition and awarded the contract to Moseme Road Construction CC, reasoning that the original advertisement had not been properly amended and that other contractors may have been prejudiced. King sought review and substitution of the award in the High Court, which set aside the award to Moseme and substituted it with an award to King. Moseme and the MEC appealed to the Supreme Court of Appeal.
