Peter's practice is focused primarily on defending major corporate clients in a variety of high exposure and noteworthy matters on both a class wide and individual basis. A substantial portion of his experience is in the area of consumer class actions in such diverse industries as insurance, pharmaceutical, medical devices and energy. Peter was the lead counsel in a case decided by the California Supreme Court which limited the application of one of California's significant consumer protection statutes, the Consumer Legal Remedies Act. As a result of the decision obtained in that case, Peter was honored in 2010 as a California Lawyer of the Year (CLAY Award) by the California Lawyer magazine. In addition, Peter co-authored "Consumer Actions and Fraud/Reliance-Based Torts," a chapter in the American Bar Association's A Practitioner's Guide to Class Actions (ABA July 2010).

Peter has enjoyed considerable success in defeating class certification in both federal and state court action. Many of those victories have occurred at the pleading stage of the lawsuit, while in other cases class certification was defeated based upon an extensive evidentiary record in connection with a class certification motion.

In addition to his class action expertise, Peter is an experienced trial lawyer who has successfully opposed at trial several well-known California plaintiff's attorneys. Peter's practice encompasses a wide range of complex commercial litigation matters including antitrust, unfair competition, products liability, and insurance coverage, marketing practices and bad faith.

Peter served as Partner-in-Charge of the Los Angeles office for more than a decade and was the head of the office's litigation practice for ten years prior to that.
