Representative Matters

Government Contractor Suspension Lifted – Agiltron, Inc.
McCarter & English successfully represented Agiltron, Inc., Nanotrons Corp., and Agiltron Development Corp. in their negotiations with the Department of the Air Force Suspension and Debarment Official of an Administrative Agreement providing for the July 26, 2013 termination of their suspension from federal government contracting.
Agency Appeal Before the D.C. Circuit Court of Appeals – LePage
Represented LePage’s in an agency appeal before the D.C. Circuit Court of Appeals and on remand before the Postal Regulatory Commission. Not only did the Court of Appeals rule in LePage’s favor, finding the agency’s decision to be arbitrary and capricious, but the Court also awarded LePage’s its attorneys’ fees under the Equal Access to Justice Act (EAJA), concluding that the agency’s decision was not substantially justified. Mr. Himelfarb then represented LePage’s before the PRC on remand and convinced the PRC to permit the licensing activities that were the subject of LePage’s license to continue.
Represented a Large Medical Device Manufacturer in Derivative and Federal Securities Class Action Lawsuits
Represented a large medical device manufacturer in several derivative and federal securities class action lawsuits, all of which were ultimately dismissed (and, in the case of the securities class action, the dismissal was affirmed by the U.S. Court of Appeals for the First Circuit).
