    John Libby is an experienced trial lawyer, working in the firm’s Los Angeles and Washington D.C. offices, who represents business entities (and their officers and directors) in criminal investigations and complex civil litigation. A former Assistant United States Attorney, Mr. Libby is uniquely positioned to advise and represent clients in litigating, through trial and appeal if necessary, complex disputes with the government and private parties, including in particular False Claims Act cases that often straddle the civil and criminal arenas.

    Mr. Libby's white collar defense practice includes the representation of corporations and their officers and directors at all phases of government investigations, including responding to search warrants, grand jury and administrative subpoenas and civil investigative demands; representation before grand juries; pre- and post-indictment plea negotiations; and all phases of post-indictment proceedings, including motions, trials and sentencing. Mr. Libby also handles complex civil litigation, including a wide variety of business torts and contact disputes for clients in the healthcare, financial services, high technology and apparel industries. 

    A significant part of Mr. Libby's practice involves conducting internal corporate investigations for corporations in response to government inquiries or internal allegations of misconduct.  In view of recent court rulings and U.S. Department of Justice guidance involving preservation of privileges and ethical considerations, such investigations must be conducted carefully and professionally.  Mr. Libby has also advised clients in making voluntary disclosures of wrongdoing to government authorities where appropriate.

    Mr. Libby's representation of clients often begins before the initiation of a government investigation or criminal or civil proceeding.  Mr. Libby is also frequently called upon to assist other attorneys in the Firm in structuring transactions to comply with applicable laws.  Mr. Libby has assisted clients in the formulation of compliance programs and has conducted compliance training.
