Bars and restaurants in New York are not allowed to refuse alcohol to pregnant women since that would violate their basic rights, the mayor's office said, according to AFP.
Pregnancy discrimination under New York City Human Rights Law "is discrimination based on gender," according to new guidelines released last week.
In 2003, a New York court found that child protection law does not apply to pregnant women whose actions could influence the health of a fetus.
Meanwhile, across the United States, restaurants, bars and any establishments serving alcohol are required to post warnings about the dangers of drinking while pregnant.
