In 1971, an act of the legislature transferred the EBNC to the newly created Department of Human Resources (DHR), and the secretary of that department was given managerial and executive authority over the board. Under a 1973 law, the Eugenics Board was transformed into the Eugenics Commission. Members of the commission were appointed by the governor and included the director of the Division of Social and Rehabilitative Services of the DHR, the director of Health Services, the chief medical officer of a state institution for the feeble-minded or insane, the chief medical officer of the DHR in the area of mental health services, and the state attorney general. In 1974 the legislature transferred to the judicial system the responsibility for any sterilization proceedings against persons suffering from mental illness or mental retardation.
The Eugenics Commission was formally abolished by the legislature in 1977.
The board sterilized about 7,600 people, many of them against their will, between 1929 and 1974, in an attempt to remove mental illness and "social misbehaviour" from the gene pool. Among the victims were 2000 young people, some as young as ten years old.
