Rand Airport Holdings (Pty) Ltd, the owner of Rand Airport, leased portions of its property to Business Aviation Corporation (Pty) Ltd and Mr Orpheus Panayiotou under an oral lease. The owner terminated the lease on one month’s notice and sought eviction. The lessees raised two defences: first, that the lease was a long-term lease still in force; alternatively, that they had effected necessary and useful improvements costing several million rand and were entitled to retain possession under an enrichment lien until compensated. The magistrate rejected both defences and granted eviction, holding that enrichment liens for lessees had been abolished by 17th-century Dutch placaeten. The High Court dismissed the appeal. Leave to appeal to the Supreme Court of Appeal was granted only on the question whether an enrichment lien exists in law for urban leases.
