"Roe v. Wade involved Texas statutes making it a crime to "procure an abortion," except when attempted to save the pregnant woman's life. 410 U.S. at 410 U. S. 117-118. Doe v. Bolton involved the somewhat less onerous Georgia statutes making abortion a crime in most circumstances, the exceptions being abortions to save the pregnant woman from life or permanent health endangerment, cases in which there was a very likely irremediable birth defect in the child, and cases in which the pregnancy was the result of rape. Those exceptions were subject to burdensome prior medical approvals, which were held to be unconstitutional. Subsequent cases have invalidated other burdens on the pregnant woman's free choice to abort. See Planned Parenthood of Central Missouri v. Danforth, supra, (consent required of husband or, for an unmarried woman under 18, of a parent); Bellotti v. Baird, 443 U. S. 622 (consent required of either parent or superior court judge for an unmarried woman under 18)."
