Morgan Chase (Chemical Bank), where he was group counsel in the bank’s Middle Market/Financial Services group.

    • Japanese auto parts investigation by the Department of Justice, Antitrust Division – In a price fixing and bid rigging criminal antitrust investigation, represented the CEO (for US, Mexico and Canada) employed by a foreign auto parts manufacturer in a federal, criminal antitrust investigation.  The investigation involved allegations that the company participated in a conspiracy with competitors to fix prices and rig bids for auto parts sold in the U.S.  The plea agreement and judgment are public documents.  I was able to secure a “carve in” status for the client resulting in his non-prosecution and grant of immunity.  Twenty-six Japanese executives have received jail sentences as a result of the Japanese auto parts investigation, the largest investigation in the history of the Department of Justice.  Over $4 billion in criminal antitrust fines have been secured against all of the auto parts manufacturers.

Revision and Lovely Skin, U.S. District for the Central District of California (Judge Gary Feess) – Represented defendant, Lovely Skin, in a price fixing claim under California’s antitrust statute, the Cartwright Act.  After the first motion to dismiss was granted, the Plaintiff was given leave to amend his claim.  The case was then settled for a nominal amount.
