Why won’t you complain? Consumer rights and the unmet product lifespan requirements

Authors: Kirsi Laitala, Lisbeth Løvbak Berg and Pål Strandbakken. Abstract The Consumer Purchases Act is one of the cornerstones for ensuring that businesses are liable for defective or faulty products that do not meet the minimum requirements for lifespans. However, this right is too seldom used by consumers. This paper discusses the reasons for not…
