Haralambos Prokas N O and Others v Zoviflo (Pty) Ltd

Zoviflo (Pty) Ltd applied to the Gauteng Division of the High Court for an order declaring it the beneficial owner of 80% of the issued shares in Prinia Investment Capital (Pty) Ltd (PIC), relying primarily on a Nominee Shareholders Agreement (NSA) and, secondarily, on a Joint Venture Agreement (JVA), both allegedly concluded on 26 March 2020. The trust owning PIC disputed that any binding agreements came into existence. It contended that the JVA was only a working document, that it was revoked before acceptance, never implemented, and later abandoned, and that the NSA was ancillary to and dependent on the conclusion and implementation of a valid JVA. Material disputes existed regarding the circumstances of signature, authority of Zoviflo’s deponent, and whether the agreements were intended to be binding. The High Court upheld Zoviflo’s claim, but the trustees and PIC appealed to the Supreme Court of Appeal.

The appeal was upheld with costs, including the costs of two counsel. The High Court’s order was set aside and replaced with an order dismissing Zoviflo’s application with costs.

The judgment reinforces South African principles of contract interpretation by emphasising context, purpose, and the interdependence of related agreements. It confirms that ancillary agreements cannot be enforced in isolation where their validity depends on a principal agreement. The case also reaffirms the strict application of the Plascon‑Evans rule in motion proceedings and cautions against resolving contested contractual formation disputes on affidavit.
