Plaintiffs' attorney William Lerach, who made a name for himself representing shareholders in securities class action suits, announced he will retire Aug. 31 from the firm he founded in 2004, Lerach Coughlin Stoia Geller Rudman & Robbins.

Lerach is perhaps best known for representing defrauded investors in class actions against companies like Enron, Qwest, Dynegy, AOL/Time Warner and WorldCom.

For seven years Lerach has been under federal investigation for his role in plaintiffs' firm Milberg Weiss' kickback arrangements. Before founding Lerach Coughlin, Lerach was the head of Milberg Weiss's West Coast operations.

Prosecutors have said the firm paid out more than $11 million to people to recruit them as plaintiffs for class action and shareholder lawsuits. In July, former Milberg Weiss Managing Partner David J. Bershad pleaded guilty to conspiracy to obstruct justice and conspiracy to make false statements under oath in connection with the kickback scheme.

“I have appreciated the opportunity to fight for the victims of corporate fraud; however, I realize that my success has made me a target,” Lerach said in a statement. “These allegations have proven to be personally time-consuming, and I have decided to focus single-mindedly on putting the matter behind me once and for all.”

Upon Lerach's departure, his former firm will be known as Coughlin Stoia Geller Rudman & Robbins.
