Another problem is the lack of a defined term. Contracts must have terms that are sufficiently defined for a court to be able to determine where a breach has occurred. It would be difficult to determine whether the buyer in a requirements contract is falsely claiming that his needs are lower than they actually are as a ploy to achieve a renegotiation or rescission of the contract. Conversely, if market conditions make the contract price a windfall for the buyer, that buyer may decide to buy more than it actually needs in order to go into competition against the seller. Courts often look to the history of dealings between the parties and to the standards within the industry to determine if the buyer is acting in bad faith for breach of contract actions on requirements contracts.
