The Supreme Court on Monday restored broad access to the abortion pill mifepristone, blocking a lower-court ruling that had threatened to upend one of the main ways abortions are provided across the nation.

The order signed by Justice Samuel Alito temporarily allows women seeking abortions to obtain the pill at pharmacies or through the mail, without an in-person visit to a doctor.

Those practices had been permitted for several years until a federal appeals court imposed new restrictions last week.
