Hamilton, which has been over-praised for its “bold” and ahistorical casting of using ethnically diverse actors play the Founding Fathers has finally crossed over the line (it was bound to happen) in a recent casting notice, according to a civil rights attorney.

According to CBS News, the attorney, Randolph McLaughlin of the Newman Ferrara Law Firm called out a recent casting notice specifying that the show was seeking “non-white” performers. He said the notice may violate the New York City Human Rights Law that forbids discrimination in hiring based on race. McLaughlin told CBS, “What if they put an ad out that said, ‘Whites only need apply? Why, African-Americans, Latinos, Asians would be outraged.”

It is possible that the ad violates the New York City Human Rights Law, which makes it unlawful “for an employer… because of the actual written or perceived… race of any person, to discriminate.”

CBS quoted a show press representative saying the wording had been approved by Actors Equity Association, the actors union, but the union was quoted denying that.

Producer Jeffrey Seller as quoted saying, “I stand by it and believe it to be legal.” The production is cast by the geniuses at Telsey + Co.

A return to the casting website Backstage.com show the modified casting notice as “extremely skilled rapper-singer-actors.”
