Final answer:
In general, a vendor cannot be exempted from warranty against hidden defects. However, in some cases, an exemption clause may be included in the sales contract.
Step-by-step explanation:
In general, a vendor cannot be exempted from warranty against hidden defects. A hidden defect is a defect that is not easily visible or detectable, and it is the responsibility of the vendor to disclose any hidden defects to the buyer. However, there are cases where a vendor may include an exemption clause in the sales contract, absolving them from liability for hidden defects. This is usually done when the buyer has been given the opportunity to inspect the goods thoroughly before purchasing or when the buyer has knowingly accepted the goods in their current condition. It's important for buyers to carefully review the terms and conditions of any sales contract or warranty to understand their rights and protections.
