Caveat venditor is Latin for "let the seller beware." It is a counter to caveat emptor and suggests that sellers can also be deceived in a market transaction. This forces the seller to take responsibility for the product and discourages sellers from selling products of unreasonable quality.
In the landmark case of MacPherson v. Buick Motor Co. (1916), New York Court Appeals Judge Benjamin N. Cardozo established that privity of duty is no longer required in regard to a lawsuit for product liability against the seller. This case is widely regarded as the origin of caveat venditor as it pertains to modern tort law in US.
