Roe v Wade dissent by Justice Byron White  

http://landmarkcases.c-span.org/pdf/Roe_White_Dissent.pdf 

 "With all due respect, I dissent. I find nothing in the language or history of the Constitution to support the Court's judgment. The Court simply fashions and announces a new constitutional right for pregnant mothers [410 U.S. 179, 222] and, with scarcely any reason or authority for its action, invests that right with sufficient substance to override most existing state abortion statutes. The upshot is that the people and the legislatures of the 50 States are constitutionally disentitled to weigh the relative importance of the continued existence and development of the fetus, on the one hand, against a spectrum of possible impacts on the mother, on the other hand. As an exercise of raw judicial power, the Court perhaps has authority to do what it does today; but in my view its judgment is an improvident and extravagant exercise of the power of judicial review that the Constitution extends to this Court.

The Court apparently values the convenience of the pregnant mother more than the continued existence and development of the life or potential life that she carries. Whether or not I might agree with that marshaling of values, I can in no event join the Court's judgment because I find no constitutional warrant for imposing such an order of priorities on the people and legislatures of the States. In a sensitive area such as this, involving as it does issues over which reasonable men may easily and heatedly differ, I cannot accept the Court's exercise of its clear power of choice by interposing a constitutional barrier to state efforts to protect human life and by investing mothers and doctors with the constitutionally protected right to exterminate it. This issue, for the most part, should be left with the people and to the political processes the people have devised to govern their affairs." Justice Byron White (a Democrat & JFK appointee).
