The justices could effectively overturn the landmark Roe v. Wade decision.
The U.S. Supreme Court on Wednesday is hearing arguments over a Mississippi law that would ban most abortions after 15 weeks of pregnancy and whether decades of legal precedent since Roe v. Wade should be overturned.
Since the 1973 landmark Roe ruling and a 1992 case that affirmed the decision, the court has never allowed states to prohibit the termination of pregnancies prior to fetal viability outside the womb, roughly 24 weeks.
Mississippi argues Roe was wrongly decided and that each state should be allowed to set its own policy.
The sole abortion clinic in the state, Jackson Women’s Health, and its allies say the high court’s protection of a woman’s right to choose the procedure is clear, well-established and should be respected.
The arguments are being heard by a court with a 6-3 conservative majority widely considered more sympathetic to abortion rights opponents than any in a generation.
Audio of the arguments can be heard live on the court’s website.
Legal scholars say the case is the most significant for abortion rights in 30 years. If the justices uphold the Mississippi law, they would be reversing a key precedent that could clear the way for stringent new restrictions on abortion in roughly half the country.
Majorities of Americans support the Supreme Court upholding Roe v. Wade and oppose states making it harder for abortion clinics to operate, according to an ABC News/Washington Post poll this month. Three in four Americans, including majorities of Republicans, independents and Democrats, say the decision of whether or not to have an abortion should be left to a woman and her doctor.
But Americans appear more sharply divided on the type of ban at issue in Mississippi. A Marquette University Law School poll this month found 37% favored upholding a 15-week ban, with 32% opposed.
Overshadowing the case is the Supreme Court’s still-pending decision in a separate dispute over Texas’ unprecedented six-week abortion ban, SB8, which has been in effect for nearly three months and dominated national headlines.
The justices gave the Texas law a highly expedited hearing, during which a majority appeared skeptical of its enforcement scheme that encourages citizens to sue anyone who aids or abets an unlawful abortion for the chance at a $10,000 bounty. Many observers assumed the court would quickly move to put the law on hold, but it has not done so.
A decision in the Mississippi and Texas cases are expected by the end of the court’s term in June 2022.
The abortion rights battle at the Supreme Court comes as Republican-led states have enacted more than 100 new abortion restrictions so far this year, according to the Guttmacher Institute, a research organization that supports abortion rights.
Twenty-one states have laws in place that would quickly impose abortion bans in the event the Supreme Court overturns Roe.
Fourteen states plus Washington, D.C., have laws explicitly protecting access to abortion care, according to Guttmacher.
