Is this women-only co-working club violating the city’s human rights law?

Article here. Excerpt:

'Officials are investigating whether or not a women-only co-working club, the Wing, has violated the city’s Human Rights Law.

The New York City Commission on Human Rights has opened a “commission-initiated investigation,” into whether the Wing has violated the law, Jezebel reported. The city bars “businesses that furnish public accommodation, including most private clubs” from discriminating against customers based on gender.

“All that’s happened is that the Wing and the commission have agreed, mutually, to sit down and have a conversation,” said Karen Dunn of Boies Schiller Flexner, who is representing the Wing.'
