Michael SpiegelMICHAEL I. SPIEGEL (1934-2012) Spiegel Liao & Kagay is saddened to announce that its senior partner Michael Spiegel passed away in August of 2012.

Mr. Spiegel was one of the founders of the Antitrust Section of the California Department of Justice, where he served as Deputy Attorney General and Supervising Deputy from 1963 to 1985.  In that position, he took a lead role in many major antitrust cases and achieved national prominence as an antitrust attorney.  He pioneered the development of modern day class action and other complex litigation.

Mr. Spiegel represented the State of California in the Western Pipe Antitrust cases; the Antibiotics Antitrust Litigation; the Western Liquid Asphalt Antitrust Litigation, MDL-50; and the Cement Antitrust Litigation, MDL-296, among many others.  He was consistently recognized by the courts and his peers as a leader in the fields of antitrust, class actions, and other complex litigation. See, e.g., In re Coordinated Pretrial Proceedings in Antibiotic Antitrust Actions, 410 F.Supp. 706, 717 (D.Minn. 1975): "Mr. Spiegel . . . [has] done an outstanding job throughout this litigation.  The Court has the highest esteem for [this man] as [an] individual and as [a] litigant."  He is best known for captaining the Petroleum Products Antitrust Litigation for all plaintiff states, an eighteen-year effort in a massive class action that ultimately netted over $140 million for four western states and their citizens.

In 1995, Forbes Magazine recognized Mr. Spiegel as one of the nation's 25 most successful trial lawyers.
