NEW YORK — Reproductive rights advocates have asked a New York City judge not to delay a plan to let women and teenage girls buy morning-after birth control without a prescription.

The delay has been requested by the U.S. Justice Department.

The plaintiffs’ attorneys filed papers Monday urging federal Judge Edward Korman in Brooklyn to require the government to immediately follow his order.

Korman ruled last month that women of any age could buy both Plan B and its cheaper generic competition as easily as they can buy aspirin.

The government appealed the order and asked Korman to postpone the effect of his decision until appeals can be heard.
