"It is often said that if men could become pregnant or if women sat in the legislatures there would no longer be laws prohibiting abortion. This is not said in jest. It reaches to the heart of the unequal position of women with respect to the burdens of bearing and raising children and the fact that they are robbed of the ability to choose whether they wish to bear those burdens. And the woman carries an unequal and greater share of the burden, not merely for nine months, but for many years, all in violation of the equal protection of the laws, as we shall discuss below. The abortion laws therefore present a rather unusual constitutional situation. At first glance, it would appear that the concept of equal protection of the laws might not even apply to abortion since the laws relate only to women. However, when we look beyond the face of the laws to their effect, we see that the constitutional test of equal protection must be applied. For the effect of the laws is to force women, against their will, into a position in which they will be subjected to a whole range of de facto forms of discrimination based on the status of pregnancy and motherhood."
