The general rule that a person cannot convey to another a BETTER TITLE to the goods than he himself has - 'nemo dat quod non habet' - is stated in which section of the Sale of Goods Act, 1930?

Section 27 of the Sale of Goods Act states the maxim 'nemo dat quod non habet': subject to the exceptions provided, where goods are sold by a person WHO IS NOT THE OWNER, and who does not sell them under the authority or with the consent of the owner, the buyer acquires NO BETTER TITLE than the seller had, even if he buys in good faith and without notice. The mandatory exceptions (mercantile agent's disposition, sale under a voidable title, seller/buyer in possession after sale, estoppel, etc., under Sections 27-30) carve out some protections. Section 30 states the 'seller/buyer in possession' exceptions. The rule protects the true owner's title.
