This chapter outlines the Sale of Goods Act 1979 (SGA), which is the set of legal rules primarily concerned with the sale of goods. It presents the history of sales law, acknowledging that the modern law of sale is largely found in the SGA. The SGA primarily aims to remove the need to consult prior case law. Thus, decisions of courts in cases prior to the Act should only be examined for guidance in cases where the language of the Act is unclear or ambiguous. The chapter then reflects on the future of sales law, which is considered to be the heart of commercial activity.
