What removes the possibility of a contract being enforced due to lack of legality?

A contract is defined as an agreement between parties that creates an obligation to perform specific duties. For a contract to be enforceable, it must meet certain legal requirements, one of which is legality. If a contract is deemed illegal, it cannot be enforced by law. This is because the subject matter of the contract contravenes public policy or statutory law, making any agreement stemming from it void.

When we refer to an illegal contract, we are talking about an agreement that involves illegal activities or violates laws and regulations. Since contracts are meant to uphold legal and ethical standards, no court can enforce an agreement that pertains to illegal acts, such as drug trafficking or fraud. Thus, the concept of legality is critical in determining whether a contract can be enforced.

In contrast, a void contract is one that is null from the beginning and has no legal effect. A voidable contract, on the other hand, is valid until one party chooses to void it, typically due to certain conditions or circumstances (like misrepresentation). An enforceable contract is a valid agreement that meets all legal criteria, including legality.

Hence, in this context, the correct option is the illegal contract, as it directly negates the possibility of enforceability due to its unlawful nature.
