The US Supreme Court on Thursday, June 13, rejected restrictions imposed by a lower court on an abortion pill widely used in the United States to terminate pregnancies. The court, in a unanimous opinion, said the anti-abortion groups and physicians challenging the medication, mifepristone, lacked the legal standing to bring the case. The case had threatened to restrict access to mifepristone across the country, including in states where abortion remains legal.

Justice Brett Kavanaugh wrote for the court that "federal courts are the wrong forum for addressing the plaintiffs' concerns about FDA's [Food and Drug Administration] actions." Kavanaugh was part of the majority to overturn Roe. The high court is separately considering another abortion case, about whether a federal law on emergency treatment at hospitals overrides state abortion bans in rare emergency cases in which a pregnant patient’s health is at serious risk.

More than six million people have used mifepristone since 2000. Mifepristone blocks the hormone progesterone and primes the uterus to respond to the contraction-causing effect of a second drug, misoprostol. The two-drug regimen has been used to end a pregnancy through 10 weeks gestation.
