Mr. Doyle also played a lead role in developing the firm’s first portfolio monitoring program for institutional investors.
In 2003 Mr. Doyle filed the first case against the New York Stock Exchange and its seven specialist trading firms for illegal trading practices and market manipulation. While at his prior firm, Mr. Doyle had the privilege of representing the California Public Employees’ Retirement System (CalPERS) as lead counsel in the NYSE securities litigation.
In the Trans Union Corp. privacy litigation Mr. Doyle served as co-lead counsel representing millions of consumers whose private credit information was alleged to have been unlawfully disclosed to third parties. Mr. Doyle successfully certified a statutory damages class action of approximately 9 million Illinois consumers and helped negotiate a nationwide settlement for consumers valued at over $109 million.
Mr. Doyle has been appointed by federal judges to be lead or co-lead counsel in numerous multidistrict litigation proceedings, including, MDL-1329 In re RealNetworks, Inc.
