This usually occurs when the parties to a contract negotiation use a third party, such as an interpreter or typist, to convey messages in both directions, and the third party makes a communication error. If a party can prove that his false belief justified errors, the contract becomes invalid. A court may also decide that a new contract is negotiated by mutual consent or that compensation will be made for the error, depending on the specific case of the error. Mutual error – each party makes a different mistake and the right to make a mistake in a particular contract is governed by the law governed by the contract. The law can vary considerably from country to country. For example, contracts concluded on the basis of a relevant error are not voidable under English law since Great Peace Shipping v. Tsavliris (International) Ltd (2002). Drafting a deal seems easy enough – until you actually do it. One of the reasons why contracts drafted by lawyers seem stilted and redundant is precisely because it is important to develop language that could be applied a decade later by strangers who were not part of the negotiations and who only have the words on the side to guide them. What is « understood without saying » by the parties cannot be understood in this way by a judge and jury interpreting the agreement a decade after the death of a contracting party. If only one of the parties is wrong, that party has no right to withdraw unless (1) the non-erroneous party knew of the error and it was his fault that caused the error, or (2) the effect of the error is such that the application of the Contract would be « unscrupulous ». See Larsen v.
John (1970) 7 Cal. App.3d 491,503; Rest. 2d, Contracts §153(a). However, most agreements are informal matters created by laymen, and the issue of vague wording, confusing wording or errors by a party regarding the purpose or intentions of the parties is common. One aspect concerns the effect of an error made by one or more parties in relation to an important fact inherent in the contract. Error of fact. This is a misconception other than an error of law. Examples include false beliefs about the meaning of a term or the identity of a person or place.
There are two types of factual errors: An error of fact is an error that was not caused by the negligence of the party making the error, that is, it does not know a fact essential to the contract. Approximate Civil Code § 1577. These categories of errors also exist in the United States, but it is often necessary to determine whether the error was a « decision error », which is a mistake from a legal point of view (given two decisions known to make the wrong one) or an « ignorant error » without knowing the true situation of things. A unilateral error is a mechanical error of calculation or perception in relation to a basic assumption on which the contract is based. For example, if the aggrieved party has assumed the risk that the assumption is erroneous, it cannot terminate the contract. For example: The law of unilateral error contracts offers two ways to correct a unilateral error in contracts. Either it can be resolved by a reform of the contract so that both parties fully understand the terms, or either party can terminate the contract completely. An error is a misconception held by one or both parties to a contract at the time of its conclusion. An error of fact may occur in the following cases: An error of fact is different from an error of law. An error of law occurs when a party makes an error in the application of contract law.
Later, in Solle v. Butcher, Lord Denning added requirements for common fairness errors, relaxing the requirements to show common errors. Since then, however, the case has been heavily criticized in cases such as Great Peace Shipping Ltd v. Tsavliris Salvage (International) Ltd.  For the Australian application of Great Peace Shipping (except in Queensland), see Svanosio v McNamara.  For Queensland, see Australian Estates v Cairns City Council.  For a discussion of the terminology used in relation to different types of errors, see: Error Categories and Terminology: Contract: Contract Law (Common Law Series) [4.79]. Common mistake – both parties make the same mistake Please note that obvious unilateral errors will only make a contract voidable if it is a mechanical error (for example, a calculation or perception error). Errors in judgment about the value or quality of an object do not make the contract questionable. For example: In contract law, an error is an error in the conclusion of a contract that certain facts are true. It may be invoked as a defence and, if successfully pursued, may result in the nullity or nullity of the agreement in question from the outset, or equitable relief may be provided by the courts. The common law has identified three different types of contractual errors: « unilateral error », « mutual error » and « common error ».
The distinction between « common fault » and « mutual error » is important. In this case, both parties believed that there had been a « meeting of spirits », but found that they had mistaken about the different meaning of the other party. This is not a mutual error, but a failure of mutual consent. In this situation, no contract has been concluded, as mutual consent is required at the conclusion stage. Restatement (second) of contracts Article 20 deals with this scenario. An error of fact is more often used as grounds for cancellation or withdrawal. This happens when the contracting parties involved unknowingly conclude the contract using false information or different meanings. If the actual information is revealed, the contract may be declared invalid or amended. An example of a common mistake would be when two parties enter into a contract in which one person agrees to carry goods for the other person at a certain cost. Later, both sides might find that the price of gas was higher than what both had negotiated, which increased transportation costs.
They could make a common mistake and renegotiate the contract with the new gas prices. Mutual mistakes in contractual affairs usually end with the contract being cancelled, so it can be renegotiated so that both parties agree on the terms of the contract. Please note that if mutual errors of acceptance make a contract voidable, an error in judgment or prediction is not. For example, in the case of errors of fact on both sides, the usual remedy is for the courts to declare the contract null and void. The parties are not bound by their terms and neither party is obligated to perform the obligations set forth in the Agreement. As in the case of a unilateral error, if the non-breaching party knew or should have known of the error, the resulting contract may be avoided by the erroneous party.
