"Texas’s criminal prohibition bans virtually all abortions performed by a licensed physician at any point in a pregnancy, except when necessary to save the mother’s life. For this reason alone, it is overbroad and therefore unconstitutional. The Georgia statute, by contrast, imposes a number of substantive and procedural restrictions on abortions. The three-judge District Court in the Georgia litigation struck down the three staturorily specified reasons for permitting an abortion, so that p .2226-1202(a) of the statute now provides that it is criminal for a physician to perform an abortion except when it is “based upon his best clinical judgment that an abortion is necessary.” Appellants argue that because of the way that the District Court severed portions of the statute, the law no longer gives fair warning as to what conduct is required and therefore is unconstitutionally vague. We need not decide that question, because the Georgia statute is unconstitutional for other reasons."
