rescind the contract on the basis of a mistake of value.
rescind the contract on the basis of a mistake of opinion.
The Correct Answer and Explanation is:
Correct Answer: not rescind the contract.
Explanation:
In contract law, a mistake can be grounds for rescission (canceling the contract) in certain circumstances. However, courts distinguish between different types of mistakes — such as mistake of value, mistake of fact, mistake of quality, and mistake of opinion — and whether they are mutual or unilateral.
In this case, both Open Range and Pinewood Ranch believed the land to be worthless, but in reality, the land is sitting atop shale rock containing valuable oil. This is a mutual mistake, but the nature of the mistake is important: it is a mistake of value, not a mistake of fact.
A mistake of value occurs when both parties are mistaken about the worth or economic value of the subject matter. Courts typically do not rescind a contract based on a mutual mistake of value, because the law expects parties to assess the value and take the risk of being wrong. If contracts could be undone just because one party later found out the deal was more or less valuable than anticipated, the stability of business transactions would be compromised.
On the other hand, a mistake of fact could be grounds for rescission if the mistake relates to a basic assumption on which the contract was made and has a material effect on the agreed exchange. But in this case, both parties knew they were buying and selling a specific parcel of land — the physical identity of the land wasn’t in question.
The discovery of oil beneath the land is a change in perceived value, not a change in the land itself. Since courts treat mistakes of value as a normal risk of doing business, they would not rescind the contract in this case.
Thus, “not rescind the contract” is the correct and legally supported answer.
