Jack is an art dealer that specializes in 17th century French Art. Jack hired chris as an agent to help locate and purchase Baroque painting. Chris was given the authority to purchase baroque paintings with a maximum of $15,000 per piece. Chris bought a Caravaggio style painting for $17,000 from Sam. Jack was shocked when he saw the cost of the painting, and he fired Chris. Not having a better idea of what to do with the painting, he put it on display in the shop with a $18,000 price tag. When the best offer he got for the desk was $14,500, Jack returned the desk to Sam. Jack told Sam that Chris had exceeded his authority in purchasing the desk, and he demanded that Sam refund the $17,000 that Chris had paid for the painting. Does Sam have to refund the money for the painting because Chris exceeded his authority? Do you think that is fair? Please I need the answer from business law book and the name of the topic.
