2 Factors influencing Consensus Parties reached consensus in a situation where they would not have concluded the contract had they been aware of the real circumstances.In such cases the contract is null and void or voidable if the prejudiced party elects do so.If the contract is null and void – no legal obligation is created.Factor which influence consensus are:ErrorMisrepresentationDuressUndue influence
3 ErrorThis is a misunderstanding / misconception by one or more of the parties regarding certain facts, events or circumstances.Error in motive (reason for conclusion of the contract:Party errors regarding the reason which motivated the conclusion of the contract.This does not influence the validity of the contract.If error was caused due to misrepresentation by the other party – such a contract is voidable due to misrepresntation and not error.
4 Error as to the contents / existence of the contract Error regarding the person with whom the contract is concluded eg. Employment contract. Error nullifies the contract.Error regarding the name of the person with whom the contract is concluded eg. Pete vs Peter. Error is irrelevant and contract remains valid.Error regarding the nature of the contract eg. Sale vs Lease. Error nullifies the contract.Error regarding the performance Error regarding the contents of the contract influences consensus. Eg. Siver vs copper. This type of error nullifies the contract provided it is also iustus error.
5 The Iustus-error approach We have to determine if the error was a reasonable and fair mistake / error before consensus will be set aside.The person claiming error must prove that error was both material and reasonable.Material = substantial enough to influence consensus.Reasonable = if it could objectively be excused in law.
6 MisrepresentationA false statement of fact made either expressly or tacitly. This can be done intentionally or negligently.Contracts = voidable if the misrepresentation has influence upon the motive or reason for the conclusion of the contract.Misrepresentation must be material and persuade the other party to conclude the contract.A person claiming misrepresentation must prove that a false statement was made.A mere expression of opinion however is not a misrepresentation. Puffing does not constitute misrepresentation.
7 RemediesIf the prejudiced party decides to elects to avoid the contract no contractual remedies are available.Restitution and Delictual damages can be claimed.Damages can be claimed for intentional and negligent misrepresentations, but not innocent misrepresentations.Eg. Contract of Sale:Actio quanti minoris – price reduction is claimed for damaged due to misrepresentation. If buyer wished to continue with the contract.Actio redhibitoria – prejudiced party claims full restitution and damages.
8 DuressDuress can cause a person to do something which they would normally not have done.It could be so serious that he acts without being aware of what he is doing – vis absoluta (loses contractual capacity temporarily, thus contract null and void)In less serious situations a person is influenced to do something he would not have done if he was not under duress. vis compulsiva (contractual capacity is retained , thus contract voidable)Requirements:Other party to the contract must be responsible for the duress.Duress must have caused the conclusion of the contract.Duress must consist of a wrongful threat of damage / harm.Contract must be prejudicial to party under duress.Threat must be of an imminent or inevitable evil.
9 Undue influence Consensus was improperly obtained. Requirements: One contracting party must have obtained influence over the other party.Influence must have weakened the prejudiced party’s resistance and rendered his will pliable and open to manipulation.Influence must have been used in an unconscionable manner.Influence must have convinced the prejudiced party to reach consensus to his own detriment.Prejudiced party reached consensus which he would not have done had there not been undue influence.
