The U.S. Supreme Court’s Casey Decision allowed states to pass laws requiring parental notification.

Typically, such a law requires the abortionist to notify one or both parents of an unemancipated minor daughter prior to an abortion, a “minor daughter” being under 18 and living at home. Under most state laws this only requires notification. In some states it also requires consent.

The court has also required a “judicial bypass.” This means that if the girl feels that she may be abused by her parents when they find out, she may go to a judge and ask for the court’s approval to abort without parental notification.
