Following discussions over an extended period, the appellants (trustees of Prinia Heritage Trust and Prinia Investment Capital (Pty) Ltd (PIC)) and respondent (Zoviflo) contemplated a joint business venture to acquire, maintain, develop, let and alienate properties through a holding company structure. Two documents were prepared: a Joint Venture Agreement (JVA) and a Nominee Shareholders Agreement (NSA), allegedly concluded on the same day. The JVA was signed by Mr Prokas (first appellant, representing the trust) on 9 March 2020 at the office of an attorney, Mr Kyriacou, under pressure but viewing it as a working document. Mr Prokas immediately thereafter went to Mr Georgiou's office (representing Zoviflo) and expressed dissatisfaction with terms not accurately reflecting prior discussions, and indicated he was not proceeding with the JVA. Mr Georgiou promised the terms would be revised. On 26 March 2020, Mr Zissimides (representing ZJ) signed the JVA. Mr Mepha (claiming to represent Zoviflo) alleged he signed both the JVA and NSA on 26 March 2020, but his signatures were not dated on the documents. On 30 March 2020, Mr Prokas emailed Ms Malan (Mr Georgiou's assistant) requesting amendments to the JVA and that the NSA be drafted by a lawyer. On 12 May 2020, a revised second JVA was circulated but never signed by Zoviflo. On 6 October 2020, the trust and ZJ passed a resolution that the joint venture was null and void, which Mr Georgiou accepted. Mr Georgiou died on 10 September 2021. In 2022, Zoviflo claimed ownership of 80% of shares in PIC based primarily on the NSA. The Gauteng High Court found in favour of Zoviflo and declared it the owner of the 80% shareholding.
The appeal was upheld with costs, including costs of two counsel. The order of the high court was set aside and substituted with an order dismissing the application with costs, including costs of two counsel where so employed.
The binding legal principles established are: (1) Where two agreements are concluded on the same day and one expressly incorporates the other and requires simultaneous conclusion, they are interdependent and form a single agreement that cannot be enforced separately. (2) An offer contained in a written document signed by one party can be revoked before acceptance by communicating the revocation to the offeree. (3) Interpretation of contracts requires holistic consideration of text, context and purpose, and where agreements deal with different aspects but relate to the same prospective purpose, they must be interpreted together. (4) Where one agreement owes its existence and purpose entirely to another agreement, the former cannot be enforced if the latter fails to come into existence. (5) In motion proceedings, the Plascon-Evans principle applies: where material facts are disputed, they cannot be resolved on probabilities and the respondent's/opponent's version must prevail. (6) Subsequent conduct of parties is admissible and relevant to determine whether agreements were concluded and parties' intentions regarding enforceability.
The Court made several non-binding observations: (1) It noted the distinction between context and background circumstances in contract interpretation has been jettisoned, and courts have navigated away from restrictive narrow consideration of words in isolation. (2) The Court observed that to seek to enforce one agreement when an interdependent agreement has failed would be unconscionable and contrary to the purpose of the agreements in context. (3) The Court commented that signing incomplete agreements (with the JVA lacking appendix 'A' and dates not filled in) was opportunistic. (4) The Court noted that Mr Mepha's lack of personal knowledge of events meant his evidence constituted inadmissible hearsay except where confirmed by persons with personal knowledge. (5) The Court observed it was unnecessary to decide the issue of Mr Mepha's authority to sign on behalf of Zoviflo, though it noted he was not appointed director until 20 January 2022, well after the alleged signing date of 26 March 2020. (6) The Court did not consider whether Mr Prokas, as one of two co-trustees acting alone, had authority to bind the trust, as this issue was not raised by the parties.
This case is significant in South African contract law for its application of interpretive principles to determine interdependence between agreements concluded on the same day. It emphasizes that interpretation must consider text, context and purpose holistically. The judgment reinforces that where one agreement expressly incorporates another and requires simultaneous conclusion, they form a single vinculum and cannot be enforced separately. The case also demonstrates the application of fundamental contract formation principles: that an offer can be revoked at any time before acceptance, and that revocation must be communicated to the offeree. It illustrates the importance of subsequent conduct in determining parties' intentions and whether agreements were concluded. The case reinforces the Plascon-Evans principle that in motion proceedings, where material facts are disputed, they cannot be resolved on probabilities and the respondent's version must prevail. The judgment also clarifies that ownership of shares is a conclusion of law requiring proper factual pleading, not mere assertion or acknowledgement in an agreement.
