"An expansion of the right to privacy to include the right of a woman to have an abortion without considering the interests of the unborn person decides this question against the unborn. The necessary consequence of that expansion would be a direct and unavoidable conflict between the unborn person’s right to life and the woman’s extended right of privacy. Assuming such a conflict, it is the position of the amici that the more fundamental and established of the conflicting rights must prevail where they clash. The right to life is most certainly the most fundamental and established of the rights involved in the cases facing the Court today."
