Clarke D. Forsythe, president of Americans United for Life, said the decision would restore power to the states and make it easier to enact “common-sense regulations” on abortion. The “partial-birth” ban, aimed at a type of abortion known medically as intact dilation and extraction, was the product of years of effort by abortion opponents in states and on Capitol Hill. The legislation was twice vetoed by President Bill Clinton and, in a previous version, ruled unconstitutional by a different makeup of the Supreme Court.
Abortion rights advocates said they were shaken by the 5-to-4 ruling upholding the ban and asserted that the ruling cut to the heart of the protections of Roe v. Wade, the 1973 decision recognizing a constitutional right to abortion. They said it also underscored the stakes of the 2008 presidential election, arguing that the next president will almost certainly appoint a justice who could shift the balance of the court on Roe itself.
