In 1973, and 1974, the practice of unpaid work in institutions was successfully challenged in the courts. In three separate court cases in Washington, D.C., Iowa and Maine, the courts ruled that unpaid resident labor in institutions is unconstitutional under the Thirteenth Amendment which prohibits involuntary servitude (peonage).
