"The appellants attack on several grounds those portions of the Georgia abortion statutes that remain after the District Court decision: undue restriction of a right to personal and marital privacy; vagueness; deprivation of substantive and procedural due process; improper restriction to Georgia residents; and denial of equal protection. A. Roe v. Wade, supra, sets forth our conclusion that a pregnant woman does not have an absolute constitutional right to an abortion on her demand. What is said there is applicable here, and need not be repeated."
