Helicopter & Marine Services (Pty) Ltd and Another v V & A Waterfront Properties (Pty) Ltd and Others

The first respondent leased a helicopter landing site at the Victoria and Alfred Waterfront in Cape Town to the first applicant. The lease required the first applicant to comply with the rules of the Civil Aviation Authority. In January 2004, the Civil Aviation Authority (third respondent) issued a grounding order under the Aviation Act 74 of 1962, suspending the helicopter's operations pending an airworthiness assessment. In February 2004, fearing the applicants would ignore the grounding order, the first and second respondents launched an urgent application seeking an interdict to restrain the applicants from operating the helicopter in breach of the lease terms and the grounding order. The Cape High Court dismissed the application, but the Supreme Court of Appeal overturned this decision and granted a final interdict in favour of the respondents.

• Whether the SCA wrongly refused to allow the applicants to collaterally attack the validity of the grounding order made by the Civil Aviation Authority
• Whether the principles for permitting collateral challenges to administrative acts as set out in Oudekraal Estates (Pty) Ltd v City of Cape Town were too narrowly drawn
• Whether the requirements for granting a final interdict were satisfied

The application for leave to appeal to the Constitutional Court was dismissed with costs. The Supreme Court of Appeal's order granting a final interdict in favour of the first and second respondents was upheld.

Where a contract requires compliance with regulatory decisions or orders, the contracting party is entitled to rely on the mere factual existence of such decisions or orders to enforce contractual compliance, even if the validity of the regulatory decision has not been challenged or determined. The proper remedy for a party disputing the validity of an administrative decision is to seek to have it set aside by a competent court, not to ignore it and rely on a collateral challenge when sued for breach of contract. A party cannot avoid contractual obligations to comply with regulatory requirements by raising a collateral challenge to the validity of those requirements where nothing prevented the party from directly challenging the decision.

The Court noted that it was not necessary to decide whether the circumstances for permitting a collateral attack as identified by the Supreme Court of Appeal in Oudekraal Estates (Pty) Ltd v City of Cape Town were too narrowly drawn, and expressly refrained from doing so. The Court also indicated, without deciding, that even if the second issue raised by the applicants (regarding the grant of a final interdict) was a constitutional matter, the applicants would have no prospects of success on that ground. The Court quoted extensively from the Oudekraal judgment, setting out the test for when collateral challenges may be permitted, particularly in cases where a subject is sought to be coerced by a public authority into compliance with an unlawful administrative act, though it did not need to apply or critique this test in the present case.

This case affirms the Constitutional Court's approach to collateral challenges of administrative decisions and clarifies the distinction between enforcing administrative decisions directly and enforcing contractual obligations that reference administrative requirements. The judgment reinforces that parties cannot use collateral challenges to avoid contractual obligations to comply with regulatory decisions. It also demonstrates judicial restraint, as the Court declined to rule on the broader constitutional question of whether Oudekraal's limits on collateral attack were too narrow, instead deciding the case on narrower contractual grounds. The case is important for understanding when parties may rely on the factual existence of administrative decisions in contractual disputes without being subject to collateral attacks on the validity of those decisions.
