U.S. Supreme Court justices brought tough questions to a Tuesday hearing in the case of an anti-abortion group challenging recent Food and Drug Administration actions loosening restrictions on the abortion drug mifepristone, with the chief inquiry being: How did the FDA hurt you?

The question of the group’s standing to sue dominated the hearing in a pair of consolidated cases over the FDA’s 2016 and 2021 decisions to relax regulations of mifepristone, the abortion pill first approved by the agency in 2000 as safe and effective. In those actions, the FDA increased the gestational limit from seven to 10 weeks and eliminated a requirement that the mifepristone be dispensed in person during the pandemic, allowing the drug to be sent through the mail for the first time.
