Law for the Prevention of Genetically Diseased Offspring (Ger. Gesetz zur Verhütung erbkranken Nachwuchses) or "Sterilisation Law" was a statute in Nazi Germany enacted on July 14, 1933, (and made active in January 1934) which allowed the compulsory sterilisation of any citizen who in the opinion of a "Genetic Health Court" (Gr. Erbgesundheitsgericht) suffered from a list of alleged genetic disorders – many of which were not, in fact, genetic. The elaborate interpretive commentary on the law was written by three dominant figures in the racial hygiene movement: Ernst Rüdin, Arthur Gütt and the lawyer Falk Ruttke. The law itself was based on a 'model' American law developed by Harry H. Laughlin.
The basic provisions of the 1933 law stated that:
The law applied to anyone in the general population, making its scope significantly larger than the compulsory sterilisation laws in the United States, which generally were only applicable on people in psychiatric hospitals or prisons.
The 1933 law created a large number of "Genetic Health Courts", consisting of a judge, a medical officer, and medical practitioner, which "shall decide at its own discretion after considering the results of the whole proceedings and the evidence tendered”. If the court decided that the person in question was to be sterilised, the decision could be appealed to "Higher Genetic Health Court". If the appeal failed, the sterilization was to be carried out, with the law specifying that "the use of force is permissible". The law also required that people seeking voluntary sterilizations also go through the courts.
There were three amendments by 1935, most making minor adjustments to how the statute operated or clarifying bureaucratic aspects (such as who paid for the operations). The most significant changes allowed the Higher Court to renounce a patient's right to appeal, and to fine physicians who did not report patients who they knew would qualify for sterilisation under the law. The law also enforced sterilization on the so-called "Rhineland bastards."
