The Partial-Birth Abortion Ban Act of 2003 (Pub.L. 108–105, 117 Stat. 1201, enacted November 5, 2003, 18 U.S.C. § 1531, PBA Ban) is a United States law prohibiting a form of late termination of pregnancy called "partial-birth abortion," referred to in medical literature by as intact dilation and extraction. Under this law, "Any physician who, in or affecting interstate or foreign commerce, knowingly performs a partial-birth abortion and thereby kills a human fetus shall be fined under this title or imprisoned not more than 2 years, or both." The law was enacted in 2003, and in 2007 its constitutionality was upheld by the U.S. Supreme Court, in the case of Gonzales v. Carhart.

Partial-Birth Abortion Ban Act of 2003 - Amends the Federal criminal code to prohibit any physician or other individual from knowingly performing a partial-birth abortion, except when necessary to save the life of a mother whose life is endangered by a physical disorder, illness, or injury.
Defines a "partial-birth abortion" as an abortion in which the person performing the abortion: (1) deliberately and intentionally vaginally delivers a living fetus until, in the case of a head-first presentation, the entire fetal head is outside the mother's body, or, in the case of a breech presentation, any part of the fetal trunk past the navel is outside the mother's body; and (2) performs the overt act, other than completion of delivery, that kills the partially delivered living fetus.Authorizes the father, if married to the mother at the time of the abortion, and the maternal grandparents of the fetus, if the mother is under 18 years of age, to obtain specified relief in a civil action, unless the pregnancy resulted from the plaintiff's criminal conduct or the plaintiff consented to the abortion.Authorizes a defendant accused of an offense under this Act to seek a hearing before the State Medical Board on whether the physician's conduct was necessary to save the life of the mother.Prohibits the prosecution of a woman upon whom a partial-birth abortion is performed for conspiracy to violate this Act or under provisions regarding punishment as a principal or an accessory or for concealment of a felony.
