"The Casey decision had partly reaffirmed the basic abortion rights ruling of 1973, Roe v. Wade, but still protected a wide range of choice for a women to seek an abortion up to “viability” — the point at which the fetus would be capable of living if delivered from the woman’s body. Many state legislatures have recently tried to ban abortions before that point, but the Supreme Court has refused to hear defenses of those new laws, and Breyer’s opinion noted that the Court still follows the 1992 standard."
