Peter S. Linden is a partner in our New York office. Mr. Linden’s practice concentrates on securities, commercial, and healthcare fraud litigation. He joined the firm in 1990 and provides litigation, arbitration and advisory services to his clients, which include: government pension funds and other institutional investors, as well as to corporate and individual consumers. He has been appointed a Special Assistant Attorney General for the State of Michigan and is a member of the National Association of Public Pension Plan Attorneys.

Mr. Linden has obtained numerous outstanding recoveries for investors and consumers during his career. His advocacy has also resulted in many notable decisions, including in In re Matsushita Securities Litigation, which granted partial summary judgment under Section 14(d)(7) of the Securities Exchange Act, and In re Ebay Inc. Shareholders Litigation, which found that investment banking advisors could be held liable for aiding and abetting insiders’ acceptance of IPO allocations through “spinning.”

Some of Mr. Linden’s relevant experience includes:
  • Representation of municipal issuers of Auction Rate Securities in FINRA arbitrations alleging misrepresentations by underwriters.
  • Lead counsel in In re Citigroup Inc Securities Litigation, a class action arising out of Citigroup’s alleged misrepresentations regarding their exposure to losses associated with numerous collateralized debt obligations.  This case settled for $590 million.
  • Representation of the State of Michigan in a lawsuit filed in Michigan State Court against McKesson Corporation, Hearst Corporation, and First DataBank, a case arising out of the defendants fraudulent scheme to increase the Average Wholesale Prices of hundreds of brand name drugs, thereby causing false claims to be submitted to the Michigan Medicaid program, and the overpayment of Medicaid pharmacy claims for such drugs and their generic counterparts.
  • Representation of the City of New York and 43 New York counties in federal Medicaid fraud actions.  KM has settled or reached agreements in principle with all defendants in these matters.  We have recovered over $225 million for the New York and Iowa Medicaid programs.
  • Representation, as lead counsel, of two major insurance companies and a bondholders class in In re Laidlaw Bondholder Litigation, a securities class action resulting in a $42.275 million recovery.
  • Chairman of the Plaintiffs’ Steering Committee in In re MCI Non-Subscriber Litigation, a consumer class action resulting in an approximately $90 million recovery for the class.
  • Co-lead counsel in Reynolds v. Beneficial National Bank.  In this case, Mr. Linden and KM successfully persuaded the 7th Circuit U.S. Court of Appeals and ultimately the district court to overturn a questionable settlement, and were then appointed co-lead counsel to the class.  Mr. Linden and KM were lauded by the district judge for their “intelligence and hard work,” and for obtaining “an excellent result for the class.”

Prior to joining KM, Mr. Linden worked as an assistant district attorney in the Kings County District Attorney’s Office from 1984 through October 1990 where he served as a supervising attorney of the Office’s Economic Crimes Bureau.
