Section 233 in The Indian Contract Act, 1872
Title: Right of person dealing with agent personally liable.
In cases where the agent is personally liable, a person dealing with him may hold either him or his principal, or both of them, liable.
A enters into a contract with B to sell him 100 bales of cotton, and afterwards discovers that B was acting as agent for C. A may sue either B or C, or both, for the price of the cotton.
Title: Consequence of inducing agent or principal to act on belief that principal or agent will be held exclusively liable.
When a person who has made a contract with an agent induces the agent to act upon the belief that the principal only will be held liable, or induces the principal to act upon the belief that the agent only will be held liable, he cannot afterwards hold liable the agent or principal respectively.
Title: Liability of pretended agent.
A person untruly representing himself to be the authorized agent of another, and thereby inducing a third person to deal with him as such agent, is liable, if his alleged employer does not ratify his acts, to make compensation to the other in respect of any loss or damage which he has incurred by so dealing.
Title: Person falsely contracting as agent, not entitled to performance.
A person with whom a contract has been entered into in the character of agent, is not entitled to require the performance of it, if he was in reality acting, not as agent, but on his own account.
Title: Liability of principal inducing belief that agent's unauthorized acts were authorized.
When an agent has, without authority, done acts or incurred obligations to third persons on behalf of his principal, the principal is bound by such acts or obligations, if he has by his words or conduct induced such third persons to believe that such acts and obligations were within the scope of the agent's authority.
(a) A consigns goods to B for sale, and gives him instructions not to sell under a fixed price. C, being ignorant of Bs instructions, enters into a contract with B to buy the goods at a price lower than the reserved price. A is bound by the contract.
(b) A entrusts B with negotiable instruments endorsed in blank. B sells them to C in violation of private orders from A. The sale is good.
