WASHINGTON — A majority of Supreme Court justices appeared skeptical Tuesday of the idea of a nationwide ban or new limits on mifepristone, the primary drug used for medication abortions.

The case was the first abortion-related hearing since the court reversed Roe v. Wade and the proceedings at time went into detail of the process and any complications of the use of medication abortion.

At issue in the case are lower-court rulings that would have rolled back recent Food and Drug Administration decisions to ease access to the mifepristone. A district court had instituted a nationwide ban as well.

But the case may simply be determined on whether the doctors who brought the original lawsuit had the ability to bring the case in the first place.

Conservative and liberal justices demanded to know why access to mifepristone needed to be limited if the small number of doctors involved could simply exercise their own religious and conscientious objections individually.

A decision is expected by July.
