The applicants were joint owners of Remainder Erf 5216 Hartenbos in the Western Cape and intended to develop the property as a group housing scheme with 22 dwelling units. The development would involve various activities listed under NEMA, including construction within 100 metres of the high-water mark, removal of indigenous vegetation, planting of lawns on dunes, and transformation of undeveloped land. In April-May 2006, the applicants filled in and compacted a depression on the property as partial construction of an access road, completing this work before the NEMA listing regulations came into effect on 3 July 2006. The applicants contended that by commencing this earthwork before 3 July 2006, they had already "commenced" all listed activities associated with their development and were therefore exempted from obtaining environmental authorisation under section 24F(1) of NEMA. The municipality indicated that environmental authorisation was required before the development could proceed. The area had previously been regarded as environmentally sensitive, with a 60-metre setback line imposed in earlier authorisations.
