This chapter discusses a Norwegian criminal case (2010–12), which concerned the exploitation of a malfunctioning trading robot by two day-traders, in light of underlying narratives about the human–robot relationship. The central argument is that legal decision-making in this case is animated by two different underlying narratives about robots: In the first, the robot is seen as a real agent operating in the market. In the second, it is viewed as a mere tool in the hands of human agents. The outcome of the case depends to a large degree on which of these narratives the court chooses as the basis of its deliberation.
