The Function of Good Faith in Commercial Contract Performance
Quick fact
In many common law jurisdictions, courts have implied an obligation of good faith in commercial contracts, meaning parties must act honestly and not undermine the other's expected benefits, even when the contract doesn't explicitly say so.

Understanding The Function of Good Faith in Commercial Contract Performance
Imagine you lease a storefront and agree to pay a percentage of your sales as rent. If the landlord then opens a competitor next door, that could directly hurt your sales and their rent. In such situations, courts often say that each party has a duty of good faith. This duty means you can't sabotage the very thing you're getting paid for. It's a background rule that fills the gaps in a written agreement. When we make a contract, we typically don't spell out every possible scenario. Good faith provides a baseline of honesty and reasonableness, ensuring that both sides get the benefit they bargained for. This is especially important in long-term commercial deals where flexibility and trust are key.
A deeper explanation
The underlying mechanism is that good faith operates as an implied term or a general principle that supplements the explicit terms of a contract. Courts use it to prevent one party from taking advantage of unforeseen loopholes or engaging in opportunistic behavior that would deprive the other party of their expected benefit. In commercial contexts, this is crucial because contracts are necessarily incomplete—they cannot anticipate every future event. Good faith provides a standard of conduct that requires parties to act honestly, not to misrepresent, and to refrain from conduct that destroys or undermines the purpose of the contract. It also fills gaps when the contract is silent on a particular matter, by requiring a party to exercise discretion reasonably. For example, if a contract gives one party the discretion to set the quantity of goods to purchase, that party must exercise that discretion in good faith, not arbitrarily to harm the other. This duty is not a relic; it is a modern tool for courts to balance flexibility and fairness in commercial relationships, preventing abuse of power and encouraging cooperation.
