"The right to live is more basic even than the right to procreate. And there is “no redemption” for the aborted child in the womb. The abortion is to his “irreparable injury” and by it he “is forever deprived of a basic liberty.” Any law which interferes with the right to live must therefore be carefully scrutinized. It is appropriate to apply here the principles which govern the application of the Equal Protection Clause to another basic right—the right to be free from racial discrimination.... There is no sufficient necessity which justifies a law which permits the killing of the child in the womb where it is not necessary to save the life of his mother. We are not concerned in this appeal with the question of whether a state law can constitutionally allow abortion where it is necessary to save the life of the mother. Rather the issue is whether the constitution permits the child in the womb to be killed where it is not necessary to save the life of his mother. To permit the child in the womb to be killed in such a case improperly discriminates against him on account of his age and situation. For the law does not allow a born child or an adult to be killed at the discretion of another or in any other situation where his killing is not necessary to save the life of another."
