Kgaswane Country Lodge (Pty) Ltd constructed a hotel and conference centre within the Magaliesberg Protected Environment without first obtaining environmental authorisation as required under the National Environmental Management Act 107 of 1998 (NEMA). After construction had substantially progressed, Kgaswane applied for ex post facto environmental authorisation in terms of s 24G of NEMA. The Chief Director granted the authorisation, and the MEC dismissed an internal appeal by the Magaliesberg Protection Association (MPA), a conservation body acting in the public interest. The MPA sought judicial review to set aside the MEC’s decision, contending that the environmental impact assessment, public participation process, and mitigation measures were flawed, that relevant planning frameworks were ignored, and that the development should be demolished and the environment rehabilitated.
