Help please! I work for a furniture manufacturer. We offer a 10 year warranty on upholstered furniture. We were recently approached by a customer seeking a refund of the full purchase price due to a fault, but it transpires he obtained the sofa for free on Gumtree. The seller mentioned when selling that her dogs and kids had destroyed it hence giving it away. It was then transported interstate. We cannot reasonably conclude that the damage is a manufacturing fault but initially the customer was offered a repair under warranty prior to finding out the circumstances under which he acquired it. He claims ACL still applies as the item is a gift. The sofa is 6 years old and the condition was poor when purchasing as noted in the Gumtree ad. Does this still fall under a private sale and therefore the laws do not apply? Or does he receive the same rights as the gift giver? I have read a lot of resources and cannot be sure.
