There are, of course, numbers of mental defectives who can never be allowed their liberty, and in the case of these the question of sterilization need not be considered. There are many cases of mentally defective girls, liberated from institutions in New Zealand for the purpose of engaging in domestic service or other work, returning afterwards the mothers of illegitimate children, probably also mentally defective. Unless such are to be maintained for years as wards of the State in institutions, should they ever again be allowed their liberty unless they undergo the operation of sterilization?

This is the question: Can the propagation of mental defect by mental defectives and the debasing of the race thereby be greatly checked if not completely prevented? The answer is assuredly, Yes, by segregation and by sterilization.

The Committee recommends that both methods be placed in the hands of the Eugenic Board, with powers to discriminate as to which method is the more suitable for each individual case. The two methods are complementary, not antagonistic, and suitable safeguards for the liberty of the subject are provided.

The Committee recommends that the Eugenic Board should be given the power in suitable cases to make sterilization a condition of release from any of the institutions under the charge of the Department of Mental Hospitals or removal of their names from the register on probation, but that in no case should the operation be performed without the consent of parents or guardians of the persons concerned.

The Committee consider that the persons so operated upon and liberated should be released on probation and kept under supervision for a reasonable period, and that they should be returned to institutional care if found to be leading an immoral life, or unable to support themselves, or for any other reason which the Eugenic Board may consider sufficient.

If the recommendation as to sterilization being authorized under the conditions specified is adopted, the Committee think it would be advisable to introduce some provision as in the American Acts, making it unlawful to perform operations whose object is the prevention of reproduction in cases not authorized by the Board unless the same shall be a medical necessity.

Section 11.—Segregation.

It will be neither possible nor desirable to segregate all mental defectives. Feeble-minded children who are receiving adequate care and training in their own homes will, of course, be left there. When they reach the age of adolescence the question of their disposal should be considered by the Board. In many cases the inmates of special schools, after they have received some training, would do well if returned to their homes or boarded out in selected foster-homes under supervision.

The real difficulty arises, especially in the case of girls, when the age of adolescence is reached.

In the opinion of the Committee it is of the utmost importance that mental defectives should be prevented from reproducing. No person who has been placed on the register should be allowed to marry until the Eugenic Board has given its consent by removing the name from the register.
