The procedure called “partial birth abortion” has lately become the subject of numerous state statutes in the wake of the controversial vetoing by President Clinton of a federal bill that would have banned the procedure. The term means an abortion in which the person performing the abortion deliberately and intentionally delivers a living fetus or a substantial portion thereof into the vagina for the purpose of performing a procedure the person knows will kill the fetus, performs the procedure, kills the fetus and completes the delivery. In the last two years, twenty-one states have enacted legislation banning or limiting the practice of this procedure. Recently, the Supreme Court held that Nebraska’s attempt to ban partial-birth abortion was unconstitutional.
