Although this opinion and eugenics remain controversial, the decision in this case still stands. Buck v. Bell was cited as a precedent by the opinion of the court (part VIII) in Roe v. Wade, but not in support of abortion rights. To the contrary, Justice Blackmun quoted it to justify that the constitutional right to abortion is not unlimited.[27] Blackmun claimed that the right to privacy was strong enough to prevent the state from protecting unborn life in the womb, but not strong enough to prevent a woman being sterilized against her will.
