In 1985 the eThekwini Municipality sold immovable property to Mounthaven (Pty) Ltd. The deed of transfer (1986) contained a reversionary clause requiring Mounthaven to erect buildings worth at least R100 000 within three years, failing which ownership would revert to the Municipality, which could demand re-transfer. Mounthaven failed to comply. The Municipality only instituted proceedings in 2014 to compel re-transfer. The High Court and Supreme Court of Appeal dismissed the application on the basis that the Municipality’s claim was a ‘debt’ that had prescribed under the Prescription Act 68 of 1969. The Municipality sought leave to appeal to the Constitutional Court.
