any of the said requirements is not present or doubt exists as to the genuineness
thereof, it may be declared void or voidable by a court of law.110
2.3.2.1 Consensus
The question of whether a contract exists, depends on whether there is an agreement
or consent of two or more parties.111 An agreement is reached when the parties
consent to be bound by contractual obligations.112 The agreement as an essential
element of a contract, must be true agreement in the sense of meeting of the minds
or coincidence of the wills of the contracting parties, that is referred to as consensus
ad idem.113 The case of SAR & H v National Bank of South Africa Ltd114 enunciated
the principle that consensus ad idem entails that the law does not concern itself with
the working of the minds of parties to a contract, but with the external manifestation of
their minds, parties shall be bound by a contract in so far as there is actual meeting of
the minds, and consensus is normally evidenced by offer and acceptance. 115
Consensus cannot be obtained through improper means.116 The quasi mutual assent
doctrine has been expressly adopted as part of South African Law.

In the
unanimous decision of Pieters & Co v Salomon, 118 which found application in Sonap
Petroleum (SA) (Pty) Ltd v Papadogianis,119 the doctrine was canvassed in the
following terms:
“…If whatever a man’s real intention may be, he so conducts himself that a reasonable man would
believe that he was assenting to the terms proposed by the other party, and that other party upon that
belief enters into the contract with him, the man thus conducting himself would be equally bound as if
he had intended to agree to the other party’s terms.”
