STORY: The court, in a 6-3 ruling powered by its conservative majority, upheld a Republican-backed Mississippi law that bans abortion after 15 weeks of pregnancy. The vote was 5-4 to overturn Roe, with conservative Chief Justice John Roberts writing separately to say he would have upheld the Mississippi law without taking the additional step of erasing the Roe precedent altogether.The reverberations of the ruling will be felt far beyond the court's high-security confines - potentially reshaping the battlefield in November's elections to determine whether Biden's fellow Democrats retain control of Congress and signaling a new openness by the justices to change other long-recognized rights.The decision will also intensify debate over the legitimacy of the court, once an unassailable cornerstone of the American democratic system but increasingly under scrutiny for its more aggressively conservative decisions on a range of issues.The ruling restored the ability of states to ban abortion. Twenty-six states are either certain or considered likely to ban abortion. Mississippi is among 13 states with so-called trigger laws to ban abortion with Roe overturned.In a concurring opinion that raised concerns the justices might roll back other rights, conservative Justice Clarence Thomas urged the court to reconsider past rulings protecting the right to contraception, legalizing gay marriage nationwide, and invalidating state laws banning gay sex.The justices, in the ruling written by conservative Justice Samuel Alito, held that the Roe decision that allowed abortions performed before a fetus would be viable outside the womb - which occurs between 24 and 28 weeks of pregnancy - was wrongly decided because the U.S. Constitution makes no specific mention of abortion rights.Women with unwanted pregnancies in large swathes of America now may face the choice of traveling to another state where the procedure remains legal and available, buying abortion pills online, or having a potentially dangerous illegal abortion.Empowering states to ban abortion makes the United States an outlier among developed nations on protecting reproductive rights, the Democratic president added.Biden urged Congress to pass a law protecting abortion rights, an unlikely proposition given its partisan divisions. Biden said his administration will protect women's access to medications approved by the U.S. Food and Drug Administration including pills for contraception and medication abortion, while also combating efforts to restrict women from traveling to other states to obtain abortions.Britain, France and some other nations called the ruling a step backward, although the Vatican praised it, saying it challenged the world to reflect on life issues.U.S. companies including Walt Disney Co , AT&T and Facebook parent Meta Platforms Inc said they will cover employees' expenses if they now have to travel for abortion services.The number of U.S. abortions increased by 8 percent during the three years ending in 2020, reversing a 30-year trend of declining numbers, according to datareleased on June 15 by the Guttmacher Institute, a research group that supports abortion rights.
