The consideration or object of an agreement is lawful, unless—

it is forbidden by law1 ; or

is of such a nature that, if permitted, it would defeat the provisions of any law; or

is fraudulent ; or

involves or implies, injury to the person or property of another; or

the Court regards it as immoral, or opposed to public policy.

In each of these cases, the consideration or object of an agreement is said to be unlawful. Every agreement of which the object or consideration is unlawful is void.

(b) A promises to pay B 1,000 rupees at the end of six months, if C, who owes that sum to B, fails to pay it. B promises to grant time to C accordingly. Here, the promise of each party is the consideration for the promise of the other party, and they are lawful considerations.

(c) A promises, for a certain sum paid to him by B, to make good to B the value of his ship if it is wrecked on a certain voyage. Here, As promise is the consideration for Bs payment and Bs payment is the consideration for As promise, and these are lawful considerations.

The agreement is void, as it renders the transaction, in effect, a purchase by the defaulter, and would so defeat the object of the law.
