The Supreme Court is reentering the abortion wars.

The justices announced Wednesday they will decide whether a widely used abortion pill can remain on the market nationwide for early-stage abortions.

In an order, the high court said it will hear a case brought by a conservative group seeking to revoke the FDA’s two-decades-old approval of the drug, known as mifepristone. Even if the justices don’t go that far, they could drastically curtail access to the drug by striking down other, more recent FDA policies that have allowed the pills to be prescribed online, mailed to patients, and dispensed at brick-and-mortar pharmacies.

The justices are likely to hear arguments in the case in the spring and to issue a decision by the end of June. Under an earlier order, current access to the medication will remain in place until the high court rules.
