I currently represent Panasonic Corporation and SANYO Electric Co., Ltd. in the defense of a consolidated multi-district antitrust litigation alleging price-fixing in the capacitors industry. I previously helped defend Panasonic Corporation in a consolidated multi-district antitrust litigation alleging price-fixing in the cathode ray tube industry. I also helped defend UnitedHealth Group, Inc. in a consolidated, multi-billion dollar, multi-district nationwide healthcare class action brought by plaintiffs’ lawyers on behalf of nearly all practicing physicians in the United States. After over six years of contentious litigation, I helped obtain a summary-judgment dismissal of all claims against UnitedHealthcare. I led a team of attorneys representing LMDC in a complex litigation in New York State court relating to the abatement and deconstruction of the former Deutsche Bank Building in lower Manhattan, which was seriously damaged in the terrorist attacks on September 11, 2001.I've also participated in a number of jury and bench trials in federal court. I participated in the representation of a white-collar criminal defendant in a highly-publicized three-month bribery, money laundering, and fraud jury trial in the Eastern District of New York. I also second-chaired a three-week tax evasion and tax structuring jury trial in the Eastern District of New York. I've also participated in a number of arbitrations, including the defense of the largest arbitration ever instituted before the International Chamber of Commerce. I currently represent CPB Contractors Pty Limited, one of the largest construction companies in the world, in separate multi-billion-dollar federal actions against Chevron Corporation and KBR, Inc., respectively, concerning disputes arising out of a liquefied natural gas project off the coast of Western Australia.
