The Swedish Sex Purchase Act has sparked considerable interest and debate internationally since it was introduced in 1999. This chapter describes and contextualizes the political process preceding the introduction of the Swedish Sex Purchase Act. We then describe its implementation and existing knowledge and assessments of its consequences. One key point is that analyses of legislation in the field of prostitution must consider the relationship between the expressed intentions of the law, the formulation of the law, and how the law is implemented. Legal measures are taken based on specific agendas, but their symbolic value and implications are transformed by the way in which the criminal law interacts with other policy domains. With the Swedish Sex Purchase Act, there has been an interaction between the feminist abolitionist agenda, which was the original basis for the policy, and other agendas. Laws are not made once and for all but are continually revised and readily appropriated by new aims, agendas, and actors.
