"The holding in Roe v. Wade, ante p. 410 U. S. 113, that state abortion laws can withstand constitutional scrutiny only if the State can demonstrate a compelling state interest, apparently compels the Court's close scrutiny of the various provisions in Georgia's abortion statute. Since, as indicated by my dissent in Wade, I view the compelling state interest standard as an inappropriate measure of the constitutionality of state abortion laws, I respectfully dissent from the majority's holding."
