Debates in the Riksdag in 1950 saw women state that the primary cause of prostitution was male demand, echoing discourse outside of government in the 1880s and 1920s. By 1958, women parliamentarians were stating that prostitution was the most important social problem of all time, demanding a further commission (1958-1962). By now, there was yet another reconceptualisation of prostitution, from psychopathology to sociopathology, and the resulting legislation replaced the vagrancy law with the antisocial behaviour law in 1964. Regulation of prostitution passed to this Act, but retained the concept of normative social citizenship based on honest labour. In practice, the law was used less and less, was successfully challenged in court in 1967, and was replaced in 1969 by the Social Services Act of 1980, till the Prohibition of Purchase of Sexual Services Act of 1999 (amended 2005).
