Introduction
Error is often described as one of the most complex parts of the law of contract. The reason for this is the clash between two opposing interests. On the one hand, a will-based theory of contract focuses on the parties being bound by having, of their own will, chosen to enter into the contract. As such, subjective will is significant. If, due to an error, a party entered into a contract believing something about the contract to be true which was not, she did not intend to be bound to the contract she ultimately entered into. On a will-based approach then, the party in error should not be bound by the contract. On the other hand, however, is the need to uphold contracts that have objectively been entered into. This is important for reasons of certainty. Parties need to be able to arrange their affairs on the basis of what the contract seems to require. It also protects the interests of the party who was not in error in entering into the contract. In framing and shaping the rules on error a legal system must thus seek to balance both positions and to adequately protect the interests of both parties.
In most legal systems it is not any error that can be used as a basis to challenge the validity of a contract. The error must generally relate to something important in relation to the contract. [1] For instance, the DCFR provides for avoidance where, but for the mistake, the mistaken party would not have concluded the contract, or would have done so only on fundamentally different terms (Art II-7:201). Many legal systems provide that an error by one party is not of itself enough to challenge the contract and they require something more, such as the mistake being shared or caused by the other party to the contract.[2] In order to protect the interests of both parties some systems, such as Germany and Greece, allow a party in error to avoid the contract but require her to pay damages to the other for losses caused due to the latter’s reliance on the contract.[3] There is therefore a spectrum between requiring full subjective consent to a contract for it to be upheld, on the one hand, and upholding all contracts objectively entered into, on the other.
