concurring:
I join the Chief Justice in holding that the hearings provided are too limited in the context of the present Act to afford due process of law. I also agree with the opinion of Mr. Justice Douglas that the scheme of classification set forth in the Act denies equal protection of the law. I disagree with the opinion of each in so far as it rejects or minimizes the grounds taken by the other.
Perhaps to employ a broad and loose scheme of classification would be permissible if accompanied by the individual hearings indicated by the Chief Justice. On the other hand, narrow classification with reference to the end to be accomplished by the Act might justify limiting individual hearings to the issue whether the individual belonged to a class so defined. Since this Act does not present these questions, I reserve judgment on them.
I also think the present plan to sterilize the individual in pursuit of a eugenic plan to eliminate from the race characteristics that are only vaguely identified and which in our present state of knowledge are uncertain as to transmissibility presents other constitutional questions of gravity. This Court has sustained such an experiment with respect to an imbecile, a person with definite and observable characteristics, where the condition had persisted through three generations and afforded grounds for the belief that it was transmissible and would continue to manifest itself in generations to come. Buck v. Bell, 274 U. S. 200.
There are limits to the extent to which a legislatively represented majority may conduct biological experiments at the expense of the dignity and personality and natural powers of a minority—even those who have been guilty of what the majority define as crimes. But this Act falls down before reaching this problem, which I mention only to *547avoid the implication that such a question may not exist because not discussed. On it I would also reserve judgment.
