Four times a week this summer — Mondays, Wednesdays and Fridays from 9:15 to 11 a.m., and Sunday afternoons from 2:45 to 4:45 — a public swimming pool on Bedford Avenue in Brooklyn will be temporarily unmoored from the laws of New York City and the Constitution, and commonly held principles of fairness and equal access.

The pool will instead answer to the religious convictions of one neighborhood group. At those hours, women (and girls, too, on Sundays) will have the pool to themselves. Men and boys will not be permitted. Orthodox Jewish beliefs demand modesty in dress, and a strict separation of the sexes, and those are the beliefs to which the taxpayer-owned-and-operated Metropolitan Recreation Center will yield.

Sex-segregated hours have been the rule at the pool since “sometime during the 90s,” according to a spokesman for the parks department. The policy was instituted at the request of Orthodox women, apparently without any serious community objections.

But a recent anonymous complaint led the city’s Commission on Human Rights to notify the parks department that the policy violated the law. Then a new pool schedule was issued, with the women’s hours removed. That alarmed female swimmers, who alerted politicians, including the local assemblyman, Dov Hikind.
