The Partial-Birth Abortion Ban Act of 2003 is constitutional because it is less ambiguous than the law that was struck down in Stenberg. It is not vague or overbroad, and it does not impose an undue burden on a woman's right to choose to have an abortion. Decided April 18, 2007 (argued November 8, 2006). Opinion of the Court: Anthony Kennedy → go there Dissenting: Ginsburg. Applied: the Fifth Amendment → go there Topic: Birth control and abortion. Gonzales v. Carhart, 550 U.S. 124 (2007), is a landmark decision of the U.S. Supreme Court that upheld the Partial-Birth Abortion Ban Act of 2003. The case reached the high court after U.S. Attorney General, Alberto Gonzales, appealed a ruling of the U.S. Court of Appeals for the Eighth Circuit in favor of LeRoy Carhart that struck down the Act. Also before the Supreme Court was the consolidated appeal of Gonzales v. Planned Parenthood from the U.S. Court of Appeals for the Ninth Circuit, whose ruling had the same effect as that of the Eighth Circuit. Wiki link
