Section 178 of Indian contract Act

Pledge by mercantile agent.— Where a mercantile agent is, with the consent of the owner, in possession of goods or the document of title to goods, any pledge made by him, when acting in the ordinary course of business of a mercantile agent, shall be as valid as if he were expressly authorised by the owner of the goods to make the same; provided that the pawnee acts in good faith and has not at the time of the pledge notice that the pawnor has not authority to pledge.

Explanation.— In this section, the expressions “mercantile agent” and “documents of title” shall have the meanings assigned to them in the Indian Sale of Goods Act, 1930 (3 of 1930).

178A. Pledge by person in possession under voidable contract.— When the pawnor has obtained possession of the goods pledged by him under a contract voidable under section 19 or section 19A, but the contract has not been rescinded at the time of the pledge, the pawnee acquires a good title to the goods, provided he acts in good faith and without notice of the pawnor’s defect of title.
