The first respondent, through the second respondent, leased a helicopter landing site at the Victoria and Alfred Waterfront to the first applicant. The lease required compliance with the rules of the South African Civil Aviation Authority (CAA). In January 2004, the CAA issued a grounding order under the Aviation Act 74 of 1962 pending an airworthiness assessment. Fearing non-compliance, the respondents sought an urgent interdict to restrain the applicants from operating the helicopter in breach of both the lease and the grounding order. The Cape High Court dismissed the application, but the Supreme Court of Appeal overturned that decision and granted a final interdict. The applicants then sought leave to appeal to the Constitutional Court.
