Appearing before Planned Parenthood’s annual convention last Friday, President Obama pledged his continuing support for women’s reproductive rights. In a speech before the National Academy of Sciences on Monday, Mr. Obama promised to keep science a sphere “not subject to politics” or “skewed by an agenda.”

On Wednesday, his administration betrayed both reproductive rights and science. The Justice Department announced that it would appeal a federal court ruling that would make morning-after pills available without a prescription for girls and women of all ages.

In 2011, the secretary of health and human services, Kathleen Sebelius, overruled the Food and Drug Administration, which had decided, based on scientific evidence, that the pills would be safe and appropriate “for all females of child-bearing potential.” Ms. Sebelius arbitrarily determined that only women 17 and older should have access to the drug.

Then, last month, citing the political nature of Ms. Sebelius’s intervention and finding no “coherent justification” for it, Judge Edward Korman of United States District Court for the Eastern District of New York ordered the F.D.A. to make emergency contraceptives available over the counter to all women, with no age restrictions.
