MEC for Agriculture, Conservation, Environment & Land Affairs v Sasol Oil (Pty) Limited

Sasol Oil (Pty) Ltd (first respondent) and Bright Sun Developments CC (second respondent) identified a property in 2000 for construction of a filling station and convenience store. They entered into an agreement whereby Sasol would supply petroleum products for sale after construction. The second respondent applied to the Gauteng Department of Agriculture, Conservation, Environment and Land Affairs for authorisation under section 22(1) of the Environment Conservation Act 73 of 1989 (ECA), as required for activities potentially detrimental to the environment. The application was supported by a scoping report. The Department had issued guidelines stating that new filling stations would generally not be approved if within 100m of residential properties, schools or hospitals, or within 3km of an existing filling station in urban areas. In September 2002, the Department refused the application primarily because it failed to comply with spatial stipulations in the guidelines - there were already two filling stations within 3km and the proposed site was within 100m of a residential area. Sasol appealed to the MEC who dismissed the appeal in April 2003. The respondents applied to the High Court for declaratory relief that the guidelines were ultra vires the ECA, or alternatively to review and set aside the decisions. Willis J refused declaratory relief but reviewed and set aside the decisions of the Department and MEC. The MEC appealed and the respondents cross-appealed.

• Whether a filling station constitutes a 'storage' and 'handling' facility for dangerous and hazardous substances within the meaning of the Minister's notice issued under section 21(1) of the ECA, thereby falling within the regulatory power of the competent authority
• Whether the policy guidelines issued by the Department were ultra vires the ECA
• Whether the decision to refuse authorisation was irrational because the guidelines were applied mechanically and inflexibly, thereby constituting a fettering of discretion
• Whether section 36(2) of the ECA creates a time bar for institution of review proceedings after internal remedies (appeals) have been exhausted
• Whether PAJA's 180-day time period prevails over section 36 of the ECA

The appeal succeeded with costs. The cross-appeal was dismissed with costs. The order of the court a quo was set aside and replaced with: 'The application is dismissed with costs.'

The binding legal principles established are: (1) The words 'storage' and 'handling' facility for dangerous and hazardous substances in the Minister's notice issued under section 21(1) of the ECA are broad enough to include filling stations as a whole, not merely isolated storage tanks and pumps. Environmental legislation must be interpreted purposively, consistent with section 24 of the Constitution and NEMA's principles of sustainable development. (2) Policy guidelines issued by environmental authorities to guide discretionary decisions are legally valid where compatible with enabling legislation, provided they are not applied rigidly and inflexibly. An affected party must demonstrate exceptional circumstances to warrant departure from policy. (3) A decision based on policy guidelines is not irrational merely because it applies such guidelines; rationality requires consideration of the specific circumstances and environmental impacts of the proposed activity. (4) Section 36(2) of the ECA, read contextually with section 35, does not constitute a time bar to institution of review proceedings after internal appeal remedies have been exhausted. The 30-day period applies only where review is pursued without first exhausting the internal appeal remedy.

The court declined to decide whether national legislation enacted as a constitutional requirement (such as PAJA) enjoys 'formal supremacy' over other Acts of Parliament, noting this was a novel question subject to academic debate but unnecessary to decide on the facts. Cachalia AJA referenced the academic debate on this point citing G Devenish 'The application of the generalia specialibus non derogant principle in the interpretation of statutes' (2005) 112 SALJ 72 at 75. The court also observed that simultaneous pursuit of both internal appeals and judicial review would be an absurdity involving wastage of costs, with no support in the statutory language. The judgment affirmed the longstanding principle from Shames v South African Railways and Harbours 1922 AD 228 that resort should not be had to courts when other specific remedies are provided, now codified in section 7(2) of PAJA.

This case is significant in South African environmental law for establishing the broad scope of environmental regulatory powers under the ECA. It confirms that environmental authorities have power to regulate entire facilities that handle hazardous substances, not merely isolated aspects of such facilities. The judgment emphasizes purposive interpretation of environmental legislation consistent with the constitutional right to environmental protection in section 24 of the Constitution and NEMA's principles of sustainable development. It validates the use of policy guidelines by administrative decision-makers in complex environmental assessments, provided they are applied flexibly. The case clarifies the relationship between internal appeal remedies and judicial review under the ECA, establishing that time limits for review do not apply where internal remedies are first exhausted. It contributes to the development of administrative law principles in the environmental context, particularly regarding rationality review and the proper application of policy guidelines.
