The Am Law Daily has learned that Cohen, Milstein, Hausfeld & Toll name partner Michael Hausfeld will be striking out on his own. The reasons for his departure were unclear but on Friday he sent a brief e-mail to attorneys he had been working with indicating that he had been “expelled” from the firm, an action he described as “abrupt and unceremonious.”

“In the meantime, I will be launching a new firm, Hausfeld LLP,” he wrote in the e-mail. “Hausfeld LLP will handle competition and other complex litigation in the United States, and throughout the world. Along with my partners and colleagues, I look forward to speaking with you in the near future.”
