HTF Developers (Pty) Ltd owned property in Pretoria which it intended to subdivide and develop for residential purposes. The Gauteng Department of Agriculture, Conservation and Environment identified the land as virgin ground and considered the clearing and construction activities to be unlawful and environmentally harmful without prior authorisation under the Environment Conservation Act 73 of 1989 (ECA). After a site inspection, the Head of Department issued a directive in terms of section 31A of the ECA ordering HTF to cease development and to submit an environmental management plan. HTF challenged the directive, contending that the land was not virgin ground and that the directive was unlawful. After litigation in the High Court and Supreme Court of Appeal, the core dispute became whether the exercise of powers under section 31A was subject to the 30-day notice-and-comment procedure in section 32 of the ECA.
