The Supreme Court on Monday announced that justices will hear oral arguments regarding mifepristone, the commonly used abortion pill, on March 26, and will decide later this year how patients can access the medication.

In December, the high court said it would hear the case brought by a conservative group challenging policies expanding access to the drug mifepristone. Those policies, issued in recent years by the FDA, have allowed the pills to be prescribed online, mailed to patients and dispensed at brick-and-mortar pharmacies.

The case, which is to be the Supreme Court’s first significant return to the abortion issue since it overturned Roe v. Wade in 2022, could affect health care for millions — including those in states that protect abortion rights — because the abortion pill is the most common method of terminating a pregnancy.
