"Legal scholars have long pointed to the shaky constitutional basis for a right to abortion. Blackmun referred to the 14th Amendment, which says that a state may not “deprive any person of life, liberty or property, without due process of law.” In earlier opinions, the court had said that liberty included the concept of personal privacy. “This right to privacy ... is broad enough to encompass a woman’s decision whether or not to terminate her pregnancy,” Blackmun declared. Earlier this year, 11 legal scholars, led by Yale’s Jack Balkin, tried to write a better opinion. Their book of essays, “What Roe v. Wade Should Have Said,” proposed several alternatives, such as saying sexual equality for women required a right to abortion."
