The rules are spoken and unspoken, enforced by social pressure but also, in ways that some find increasingly disturbing, by the modesty committees. Their power is evident in the fact that of the half dozen women’s clothing stores along Lee Avenue, only one features mannequins, and those are relatively shapeless, fully clothed torsos.
The groups have long been a part of daily life in the ultra-Orthodox communities that dot Brooklyn and other corners of the Jewish world. But they sprang into public view with the trial of Nechemya Weberman, a prominent member of the Satmar Hasidim in Brooklyn, who last week was sentenced to 103 years in prison after being convicted of sexually abusing a young girl sent to him for counseling.
Mr. Weberman, an unlicensed therapist, testified during his trial that boys and girls — though not his accuser — were regularly referred to him by a Hasidic modesty committee concerned about what it viewed as inappropriate attire and behavior.
The details were startling: a witness for Mr. Weberman’s defense, Baila Gluck, testified that masked men representing a modesty committee in the Hasidic village of Kiryas Joel, N.Y., 50 miles northwest of New York City, broke into her bedroom about seven years ago and confiscated her cellphone.
The Brooklyn district attorney, Charles J. Hynes, who prosecuted the Weberman case, has now received allegations that members of a modesty committee forced their way into a home in the borough, confiscating an iPad and computer equipment deemed inappropriate for Orthodox children, officials say. Allegations have also surfaced that a modesty committee threatened to publicly shame a married man who was having an affair unless he paid the members money for what they described as therapy.
“They operate like the Mafia,” said Rabbi Allan Nadler, director of the Jewish studies program at Drew University in Madison, N.J.
Rabbi Nadler, who testified at Mr. Weberman’s trial, said that modesty committees did not have addresses, stationery or business cards, and that few people seemed to know where their authority originated, though it was doubtful, he said, that they could continue operating without the tacit blessings of rabbinical leaders.
