In November 2012 Benjamin Pershouse bought a pair of women s indoor slippers through L L Bean s website Pershouse said that after a few years of indoor use the rubber soles of the slippers began to flake off in large chunks He did not say that the slippers were defective or that he was dissatisfied with their quality In February 2018 L L Bean s executive chairman posted a letter on the company s Facebook page announcing a change in founder Leon Leonwood Bean s longstanding policy of if something s not working or fitting or standing up to its task or lasting as long as you think it should we ll take it back The letter indicated that A small but growing number of customers has been interpreting our guarantee well beyond its original intent Some view it as a lifetime product replacement program expecting refunds for heavily worn products used over many years Others seek refunds for products that have been purchased through third parties such as at yard sales The letter then announced Based on these experiences we have updated our policy Customers will have one year after purchasing an item to return it accompanied by proof of purchase After one year we will work with our customers to reach a fair solution if a product is defective in any way In March 2018 Pershouse attempted to return the slippers to an LL Bean store in Burlington Massachusetts He had proof of purchase but the clerk refused to take the slippers back Pershouse then filed a class action lawsuit against L L Bean on several grounds including breach of contract breach of warranty and unjust enrichment Do you think Benjamin was in the right for filing suit Do you think LL Bean had an obligation here What could maybe have been a resolution without having to go to court This is a real court case but I m looking for your opinion on this issue No research needed just share your thoughts Be sure to meet minimum requirements for writing assignments
