MISTAKE IN A CONTRACTUAL SENSE |
Where a contracting party acts while under an incorrect impression regarding some other fact that relates to or affects the contract between the parties. |
Declared Intention vs. Subjective Intention |
All contracts are based on consensus between the parties to it. Often, the parties think that they are in agreement and have reached consensus, but in fact are mistaken. If the contract is concluded and it later turns out that it was based on the mistaken belief that a certain state of affairs existed when in fact it did not, the aggrieved party may want to opt out of the contract, or claim relief from the other party. |
MISTAKE |
- Parties APPEARED to have reached an agreement. However, one/both parties have different subjective intentions. |
CASUAL MISTAKE |
-Affects the mistaken party's decision to contract. |
-The party would either: |
a) have not contracted at all OR |
b) would have contracted on different terms |
Relevant |
NON-CASUAL MISTAKES |
-The party would have still contracted regardless of the mistake |
Irrelevant |
MISTAKE IN MOTIVE |
-Only affects a party's reasons for contracting |
-Despite the mistake, there is still subjective consensus between the parties on the terms, parties and animus contrahendi |
ESSSENTIAL (MATERIAL) MISTAKE |
A mistake is essential (material) if it is casual AND it leads to dissensus (a lack of subjective consensus) between the parties on any of the following aspects |
a) Terms |
b) Parties, or |
c) Animus Contrahendi |
*Khan v Naidoo 1989 (3) SA 724 (N) |
TYPES OF MISTAKES |
Unilateral Mistake |
Where only one party makes a casual mistake. |
Effect: Dissensus (lack of consensus): VOID |
Mutual Mistake |
Both parties make casual mistakes, but they make different mistakes. |
Effect: Dissensus: VOID |
Common Mistake |
Both parties make the same mistake and the mistake is casual for both of them. |
Effect: Consensus based on common false supposition (STILL VOID) |
*Allen v Sixteen Stirling Investment (Pty) Ltd |
*Shepherd v Farell's Estate Agency |
MATERIAL AND NON-MATERIAL |
Material |
1) Goes to the heart of the contract |
2) Completely negates consensus |
3) No contract can be said to have existed |
Non-Material |
1) Does not exclude actual agreement |
2) A valid contract comes into existence |
3) The contract is voidable (rescindable) if consensus was reached improperly: by way of duress, undue influence or commercial bribery. |
Material Mistake: |
Parties must: |
1) serious intention to contract; |
2) be of one mind as to material aspects; and |
3) be aware that all parties are of the same mind |
If one or more of the above is lacking = MATERIAL MISTAKE |
(a) Mistakes re parties to a contract |
National and Overseas Distributors Corporation (Pty) Ltd v Potato Board 1958 (2) SA 473 (A) |
(b) Mistakes re material terms |
Allen v Sixteen Stirling Investments (Pty) Ltd |
(c) Lack of understanding of legal consequences of a contractual provision - usually unaware |
- where a party is mistaken as to the contents of the obligations that the parties wish to create. Any mistake arising therefrom is material. |
Du Toit v Atkinson's Motors Bpk 1985 (2) SA 889 (A) |
Non-material mistake: |
- Does not affect the consensus. |
Error in motive: |
- Mistake regarding the reason/motive for the mistaken party agreeing. |
Mistake - The Roman System of Classification |
(1) error in corpore: mistakes can relate to the subject matter of the contract (material) |
(2) error in negotio: mistake re the true nature of the contract. *Khan v Naidoo 1989 (3) SA 724 (N). (material) |
(3) error in persona: mistake re the identity of one of the parties to the contract. (sometimes material) |
(4) error in substantia: mistake re an attribute or characteristic of the subject matter of the contract, i.e. it does not render the contract void. (usually not regarded as a material mistake) |
(5) error in motive: mistakes as to the party's reasons for entering into the contract. (not material) |
Kok v Osborne 1993 (4) SA 788 (SE) |
The seller accepted an offer ostensibly made by two buyers jointly. However, the offer was actually from only one buyer. It was clear that the defendant in that instance would not have accepted the offer had he known the true position (error in persona) |
HOWEVER... in Venter and Others v Credit Guarantee Insurance Corporation of Africa Ltd. 1996 (3) SA 966 (SCA) - error in persona is material only if the identity of a party is of vital importance to the mistaken party. |
JUSTUS ERROR |
1) material error |
2) reasonable error |
Allen v Sixteen Stirling Investments (Pty) Ltd. |
Sonap Petroleum SA (Pty) Ltd (formally known as Sonarep (SA) (Pty) Ltd) v Pappadogianis. |
FACTS: |
S and P entered into a finance lease. The agreement was supposed to provide for a lease of the premises for a period of 20 years, after which P would be the owner of the property. However, when S submitted the written offer to P, the period of the lease was accidentally given as 15 years instead of 20 years. P, fully aware of the discrepancy, readily accepted as the 15-year lease period as it meant that he would acquire ownership of the property sooner. When S realised the mistake and tried to change the lease period to 20 years, P refused. |
COURT HELD: |
S was the mistaken party, since its declaration (the written contract of lease of 15 years) differed from its true intention (that it wanted to lease the property for 20 years). There was therefore a misrepresentation of contractual intention by S. However, P knew that S wanted to lease the property for 20 years and not 15 years. P had not honestly relied on the impression created by S signing the contract. P was 'snatching at the bargain' - even though he knew what S' true intention was, he was trying to enforce the written contract. S was not bound by the written contract because there was no reliance by P. |
Rectification: |
- sometimes, when committing negotiated terms to a written format, a failure to correctly indicate the common intention of the parties occurs. (unintentional) |
- remedy for correcting mistakes in written contracts. |
- generally, parties can correct themselves (by agreement) or simply perform as per the correct intention. |
(1) in the event of a dispute - a party may apply to court for rectification or correction of the written document - allows for the correct actual common intention of the parties to be reflected |
(2) where a person applies to court to 'rectify' a contract that he has entered into, he is asserting that the written contract, as it stands, does not accurately reflect the true intention of the parties, and he is asking the court to order that the contract be rephrased so as to accurately reflect the true mutual agreement of the parties at the time they entered into their agreement. |
(3) remedy available only where all the parties to the contract were in fact of one mind, but the written contract failed to accurately express their consensus. |
(4) rectification is therefore not a remedy that is available where only one or some of the parties were under a misapprehension or mistaken impression |
(5) rectification does not create a new contract, nor does it amend an existing contract; it merely serves to correct the written memorial of the agreement so as to accurately express the true intention of the parties. (Boundary Financing Ltd v Protea Property Holdings (Pty) Ltd [2009] (3) SA 447 (SCA)) |
