Sullivan & Cromwell, the law firm accused last month of sexual discrimination against their associate Aaron Brett Charney, is now filing their own complaint. Back in January, Charney filed a $15 million lawsuit in Manhattan Supreme Court, claiming he was ridiculed and tormented when his bosses at the firm learned he was gay. The firm denies these allegations. Last week, Sullivan & Cromwell said that Charney broke his attorney-client privilege by publicizing his complaint in the press and on an Internet discussion board called Greedy Associates. The firm also implied that Charney stole proprietary documents from a neighboring office and leaked them to the Wall Street Journal. The suit was filed in Manhattan Supreme Court by another New York firm, Paul, Hastings, Janofsky & Walker, requesting a judge force Charney to return the documents and award the firm damages. Hell hath no wrath like a law firm scorned.
