§ 1598 Void Unlawful Contracts
This law says that if a contract is about only one thing and that thing is illegal, impossible, or too unclear, then the whole contract is considered void.
A person hires a contractor to build an addition on their house, but the contractor promises to use a material that is banned by law.
Because the single goal of the contract (building the addition) includes an illegal part (using the banned material), the entire agreement is treated as void and cannot be enforced.
