As between two constructions, each reasonable, one of which will make the contract enforceable, and the other of which will make it unenforceable, that construction which makes the contract enforceable will be preferred.1 Thus if a contract is fairly open to two constructions, one of which will accomplish the intention of the parties and the other of which will defeat such intention2 or will make the contract meaningless,3 the former construction is to be preferred. So if one construction will make a contract legal and another will make it illegal the former is to be preferred.4 So a construction which will accord with public policy is to be preferred to one contrary thereto.5 If the interest of the public is affected by a contract, it should be construed so as to protect such interest.6
