The Supreme Court is set to rule on the legality of the abortion pill mifepristone. If the court rules in favor of the plaintiffs, other drugs could be challenged.

Vaccines, birth control pills, hormone therapies and fertility drugs would be the subject of new litigation. The pharmaceutical industry has expressed alarm and has told judges and anyone who will listen that giving federal judges the power to overturn the agency's scientific conclusions on health and safety would create chaos in the sector. The Supreme Court has a 6-3 conservative majority that has been hostile to abortion rights.
