Five months after ordering the Food and Drug Administration to allow the marketing of the emergency contraceptive Plan B to 17-year-olds without a prescription, a Brooklyn federal judge has refused to allow three Christian lobbying groups who oppose abortion to challenge the ruling.

In his latest decision in the case, Eastern District Judge Edward R. Korman held that Concerned Women for America, Christian Medical & Dental Associations and Christian Pharmacists Fellowship International failed to show they were harmed by his March 23 ruling and thus lacked standing to challenge his decision to allow over-the-counter sales of the pill.
