"Has the arbitrariness of Roe v. Wade been overcome since 1973? No. Here the discussion must focus on the 1992 decision of the Court in “Planned Parenthood v. Casey”, which reaffirmed “the central holding” of Roe. In Casey we hear the Court (the “joint opinion” of Justices Kennedy, Souter, O’Connor) note the disagreement among us about the “profound moral and spiritual implications” of abortion. “[B]ut that cannot control our decision. Our obligation is to define the liberty of all, not mandate our own moral code.”"
